That's cool. I like all the labels for the lines. Have you taken it out yet?  

Rick D

I saw quite a few running around Marina del Rey (CA) a few decades ago. Have not seen any recently, but I'm sure they are still around. Looks like a very fun boat.

The Lake Harriet Yacht Club here in Minneapolis has a number of them that they use for their adaptive sailing program for sailors with physical challenges. They are really cool boats and I'd love to get in one. Scroll down to the bottom of the page to get to this program. https://www.lhycsailing.com/racing/

I watched Dennis Conner and Terry McLaughlin match race mini-12's in Bedwell Harbour, South Pender Island many years ago.Brings back memories!

Congratulations on your acquisition. Many years ago there were a couple of mini 12s at a local club. A friend was a member there and invited me to sail with him. We had a blast racing around the bay in them for a few hours one afternoon. The ones I sailed had a tiller in front of the seat rather than foot pedals. The tiller controlled the rudder through ropes so I can see how you could adapt either way. I believe they were set up for paraplegics without use of their legs. Very fun boats with a lot of strings to pull so they can be quite technical to race.

It a 2.4M class boat. The illusions (I think) were made in the UK. Norlin also made them in Sweden. Quite the blast. Busy slow. As Danny notes the are a good AS boat, as long as the student has the mobility to get in, and the motor control to use the controls solo. At WYC we use adapted Solings.  

Brian, Toyed around with it last year. It's a real blast to sail. Remarkably fast and turns on a dime. Takes a little while to get use to it. Foot pedal steering is a little strange at first. I haven't used the spiniker yet because that halyard was not working last year. Over all this thing really is awesome to sail. Last year had a few learning curves to work out. One thing I did learn right out of the gate was how to launch it from the trailer. 1st attempt didn't go as planned. Put the mast up and all the standing and running rigging up with out any issues. Removed all the tie down straps from the trailer. Rolled it back down the ramp, so far so good. It started to float, and had to give it a little push to clear the trailer pads. Then it slipped off the trailer and floated back about six feet. Few seconds later it capsized and sank. I forgot to put the lead waight sin the keel, was a little top heavy. Fortunately nobody was around to see that, but I still thought it was pretty funny nevertheless. What guy ever reads a manual. After about an hour trying to get it floating again. Went sailing for hours, and had a blast. My wife said that I told her that I was only going to be out on the water for an hour. I was gone for two, but when I told what had happened, the one hour it took to re-float it doesn't count for my sailing time.

Hi, I looking at a mini 12 mtr. on trailer. I am glad I read about the chap who launched his off the trailer fully rigged and it rolled over. I would have done the same.  

Looks like a fun boat. All the skippers looked to be wearing dry suits. Makes me think it is a wet boat to sail. With so much of the hull beneath the water and so little free board, how do you keep it afloat? It looks like it could easily become a submarine. A fun one.  

⛵

It looks like a blast to sail. I would be up for a test sail If I found one.  

Tom J

Capt Robbie said: JSsailem, Very little freeboard, and you do get wet a lot, but that's half the fun!! It has air tight compartments to prevent it from sinking, however you can submerge the stern. That makes it a little chalanging to get going again. Just learned how to pump out fast Over all still a blast to sail. Click to expand

The International 2.4mR Class Updated February 22, 2005

   

Background:

After the 1980 America's Cup in Newport, Rhode Island a new "class" of boats was introduced to the sailing world. Because of their resemblance to the 12 Meter yachts sailed in the America's Cup they were called "Mini 12's".

Mini 12's became popular as many sailors discovered that family and business commitments prevented them from using their larger yachts. Mini 12's offered an excellent opportunity to resume racing without investing large amounts of money and available leisure time.

The International 2.4mR Class:

Within two years of the debut of the "Mini-12", the Scandinavian Peninsula became the development site of an even more sophisticated yacht -- the 2.4mR yacht. Designed by Peter Norlin , Sweden's renowned naval architect, along with a number of other designers, these boats met the design criteria of the International Meter Rule. Peter Norlin’s design also enabled physically challenged sailors to adapt the sailboat to their specific needs. This has provided disabled and able-bodies sailors an opportunity to successfully compete against one another.

Organized in 1986, the International 2.4mR Class is well established in the Scandinavian countries and around the World. It is not unusual to see 50 or more 2.4mR boats at the starting line of a race.

The 1996 2.4mR World Championship in Cannes, France (October 1996) had seventy-five (75) Norlin yachts starting in a seventy-nine (79) yacht fleet. Peter Norlin won the 1996 2.4mR World Championship, and placed second in the 1997 2.4mR World Championships. Eighty-one (81) of eighty-six (86) yachts were Norlin designed.

The 1998 World Championships had over 100 boats registered. What a start line that proved to be. 1999 was another banner year for the World Championships with over 90 boats registered.  With many World Championships sailed in Europe, where most of the fleets reside, 100 or so boats are not uncommon at the start.  The United States hosted the 2002 World Championship with 55 boats representing more than seven nations at the start.

The International 2.4mR Class is a "development class". It is not yet strictly defined as a "one-design" class. Subtle changes may be made if the modifications remain within the Meter Rule. There is considerable discussion within the International Sailing Federation (ISAF), formerly the International Yacht Racing Union (IYRU), and other organizations around the world to make the class a true "one-design".

The Swedish 2.4mR Class has asked many 2.4mR owners, racers and builders, for their position on the 2.4mR Class becoming a true One-Design Class. See Standardization below.

Characteristics:

The International 2.4mR Class is growing worldwide. In November 1992, the International 2.4mR Class, and the Norlin Mark III, was adopted into the IYRU. This has provided an additional measure of acceptance and strength to the popularity of the design.

The Norlin Mark III is ideal for either the beginning, physically challenged and experienced sailor. Due to its design, it’s an excellent "racing machine". It incorporates all of the major sail control features of other meter yachts such as a boom vang, backstay tensioner, outhaul, traveler, cunningham, etc. All sail trim controls are led to a console forward of the helmsman’s seat, below the main deck. Steering is controlled either by foot pedals or hand controls. The hallmark of the Norlin Mark III is its unique design and versatility. As a fixed-keel yacht it is virtually non-capsizable. If it is swamped, it will not sink as a result if its built in positive foam flotation.

Simple, yet thrilling to sail, the majority of your body remains below the waterline. The Norlin Mark III provides an incredible rush of excitement. Many racers describe it as the Formula 1 race car of sailing. There is nothing you can’t learn from sailing a Norlin Mark III, as you are the skipper, tactician and crew.

Sailing Diversity:

The characteristic features of the fixed keel, displacement yacht makes the size of the skipper meaningless. Men, women, disabled and beginning sailors are at no disadvantage due to weight or other body characteristics. The Norlin Mark III requires little physical exertion to sail, allowing each sailor to compete evenly. Sailing ability is the critical factor to winning, not strength . The Norlin Mark III provides one of the few forms of competition where disabled and able-bodied persons can compete on an equal basis.

Standardization:

A strong class association is important for active sailboat racers. This will protect their fleet through standardization of design and promotion of the design to increase the popularity of the class. Standardization enables owners to compete throughout the world with other racers who own boats sharing identical specifications.

Peter Norlin, designer of the Norlin Mark III, will propose to the ISAF that this boat become a one-design class, still adhering to the Rules of the International 2.4 Meter Class. This proposal, when approved, will protect the owner’s investment for many years to come. It will also allow the Norlin Mark III to be a candidate for the Olympics, as one of the considerations for selection is a one-design class boat. The results were not favorable for a One-design Class so it will be tabled until a majority of National Class Associations vote in favor of the One-design concept.

One-design standardization:

As stated above, a strong class association is important for active sailboat racers. On July 14, 2000, the US 2.4mR Class voted to abandon the US 2.4mR Class and start a new One-design Class with the Norlin Mark III as the basis. This was done after a worldwide vote to allow this One-design Class to be implemented and administered by the International 2.4mR Class.

The new Class is the United States N3 Class Association. All current memberships were transferred to the new Class. A number of other countries have already voted for a One-design Class and may follow the lead of the United States.

At the ISAF Annual General Meeting in November 2000, the International 2.4mR Class put off the petition to the ISAF to infer International status to the N3 Class boats, even though a number of countries were in favor of this development and the fact that N3 Class boats are being built in four countries on four continents.  Since the vote was put off, the One-design issue has been tabled.

In lieu of this, the United States reverted back to the development class status and renamed itself the United States 2.4mR Class Association at the July 2004 Annual General Meeting.

Transportation:

The Norlin Mark III can be transported as an entire unit on a specially designed road trailer or small utility/yard trailer. With the lead ballast removed, the Norlin Mark III weighs approximately 145 pounds. Car topping is possible. These features provide the opportunity to keep the yacht at home and travel easily from one sailing site to another.

Fleet Sites:

The US fleet was started in Florida and congregated in the St. Petersburg, Sarasota, Fort Lauderdale and Miami areas. A number of new fleets have recently been created and are growing in number of boats in Darien, CT, Stamford, CT, Bangor, ME, Northeast Harbor, ME, Lake Norman, NC, Savannah, GA, San Diego, CA and Sylvania, OH.

Norlin Mark III:

The Norlin Mark III is the current World Champion 2.4mR yacht. It has not lost a World or National championship since 1990. SAILINGWORLD TM magazine selected it as the 1994 BOAT OF THE YEAR in the One-Design/Day Sailer category. Numerous articles in many separate publications have since been written and published about the boat.

The Norlin Mark III is sailed by more than 80% of the active 2.4mR sailors in the world and it makes up 95% to 98% of the boats registered in the World Championships. It is the boat of choice in this class. It is manufactured on four continents: Europe; North America; South America; and Australia.

In November 1997 the ISAF chose the Norlin Mark III as the boat raced in the 2000 Paralympics, Sydney, Australia, the 2004 Paralympics, Athens, Greece, the 2008 Paralympics, Beijing, China and the 2012 Paralympics.

There is a movement underway to introduce the boats as a Demonstration Class at the Summer Olympic games. The introduction of the Norlin Mark III and its inevitable International Class status as a true One-design boat, should help move this project along.

Just wondering about this. A local boatyard has one of these things sitting around, trying to sell it for the owner. About 10' long, with the lines of an old America's Cup racer. Supposedly has the rigging and other important parts, plus a cradle. So-so condition overall. Originally they said $100, when they called the owner he said $300 and I sort of blew it off. Now looking around the internet I'm wondering if it might be worth going back and haggling for.  

Mr. Snoid

Feats Don't Fail Me Now

Would love to see a pic of that boat...sails would probaly run $2K just for an average main and jib...not to mention what TLC the rigging needs...I would bet it would be a beautiful one off when its done but it will cost $$$ to get into that game.

They are very attractive, but more like toys than real boats. Then again, for a couple of hundred bucks, it may be worth picking up. You'll pay far more that the purchase price to bring her back to proper sailing trim, I suspect. Wood hull or fiberglass?  

Fiberglass hull, has a few chips and a crack on the deck. Not sure of the brand but I think it's an Illusion. I gather most of these were made in the '80s before the 2.4m class was developed. It has at least a mainsail and probably the full kit. They had the rigging stashed inside and I didn't look at it. It's outfitted with a tiny little roller furler for the jib. The ballast was also out of the boat when I saw it. Not sure if it's missing or what. All the rest of the hardware is there, including a big bilge pump. Here's the general style: http://www.sailingtexas.com/sillusionmini12b.html

Mini 12 I have one of these they are lots of fun to sail. Mine is an Oberg & Davis they were in Bristol Rhode Island and are since gone. Gavia yachts still makes them they are in Conn. I live in Hopedale Ma. Here is a link to the only U.S manufacterer http://www.gaviayachts.com/leader.htm  

Thanks. What do you figure one needing TLC might be worth?  

  • Jun 15, 2007

2.4 metre It depends really on the condition if the keel ballast is still there as well as the rigging and all it needs is cosmetics $1500 $2000 if there is significant peices missing it could turn into an expensive project. I've seen these go on ebay for anywhere from $1500 to $4500. Let us know what you decide to do I may be interested in it if your not.  

  • Jun 22, 2007

Talked to the owner today, going to look at it tomorrow. Needs a couple cracks in the deck fixed (minor, I've seen them), needs sheets and halyards, and a coat of paint. It has full gear and hardware, has both sails but in unknown condition. Might have a whisker pole, not sure. Comes with a little cradle. Ballast is missing but this series used bags of lead shot to adjust to the pilot. Over the phone he said $200, but I think he'd take less. Has that sound to his voice. I figure I can't go wrong for that price.  

Look forward to some pics...heck at that price you can't go wrong...those look like they may be a lot of fun to play in the wind...a  

  • Jul 6, 2007

Looks like I bought it. The owner's opinion of the boat appears to have gone down since I last talked to him. 60 cans of Budweiser for his boatyard buddies and its mine. Pics to follow over the weekend, hopfully.

Not much progress on the boat. I've discovered how the mast was made and hopfully how to make a new one with what I have. Also found a few former and current owners of these things in town. Turns out there used to be a big fleet back in the '80s but the fad passed.  

  • Sep 14, 2007

Started tearing it apart last week. Stripped down to a bare hull, sanded everything, even removed the rudder tube and fittings. I have a all-new steering system waiting to go in. Now I'm starting to reassemble things, and just today I started repairing the deck crack and fairing the hull. Looks like it was a small builder's product. Hull seems copied from an Illusion, the rigging is Illusion, but the deck and interior combine features from many boats and original ideas. It's not made as well as a real Illusion I looked at a few days ago.  

keep em' coming John (the updates)!!...and good luck with the overhaul...a

Very cool looking. Looks like only a small person could sail her comfortably. How about retrofitting the keel to a winged version for improved windward performance? Like to see pics when fully rigged...

Over here they are mainly used by disabled people to race in, since it is a really safe boat. it looks good on the water and is souppoused to sail quite well but I newer had the chance to sail in one, my brother did and he liked it.

John, That's the best use of Budweiser I've seen since using it as a glass rinse! Way to go. :thmbsp: P.S. Bet the wife's happy, too.

John: What is the hull number? The first 3 letters are the identifier for the manufacturer. The hull number should be somewhere on the edge of the upper deck near the stern or else on the upper part of the hull itself. The boat looks very much like a Millimeter Mini 12. I have a 1983 Millimeter and your boat looks like a newer version of mine. People always call these Illusions when in fact the Illusion was only build in the UK. Some were imported into the US and at last count that I know of, there were only 75 true Illusions in the US. There were other versions build under similar specs by various manufacturers in the US and elswhere. Your hull ID number will go a long way to identifying the manufacturer of this particular boat.

This is an Illusion Mini 12, it is a single person racing boat that was designed to look like the America's Cup 12 meter racing boats. They were first produced in the early 80's, and you can get new ones today for about $7000. They became very popular with older sailors because they have all the control lines of a big boat, but are only piloted by a single person so you don't have to worry if your crew is going to show up or not. (you don't have to use all the control lines, can sail just fine with just the basics) Another big aspect of racing them is that because you sit inside and can't hike out, it doesn't matter how athletic (or non-athletic) the captain is, everyone is equal.

Very comfortable to sail, has a molded seat that is nice to sit on and you steer with your feet. Doesn't feel like a kayak, and the opening where you get in is so large that it is very easy to get in and out of, and don't feel like would become entrapped in it if capsized. Just a hoot to sail, very fun - really is a keel boat that you can drive against the wind and heal way over. Very unique feeling being right there next to the water. Has a bilge pump mounted just forward of where you sit so if you take on water, can pump it out. Also has full reserve floatation so if you become totally swamped it will float so you can bail the water out.

Currently this one has 250 lbs of loose lead in the keel, and I weigh almost 300 lbs and the hull floats above the waterline, so more ballast could be added. Originally designed to have bags of lead shot put in the keel, but I have some bars lead and some wheel weights in bags in there. The trailer is included, roller furling jib, main, spinnaker and whisker pole. All sails are in excellent shape, very crunchy and practically new.

The 115 year-old  International 12 Metre Class  encompasses a living history of racing yacht design by the world’s foremost naval architects including Olin Stephens, Clinton Crane, William Fife III, Philip Rhodes, Johan Anker, Ben Lexcen and more who pushed their designs to the very limits of innovation. The resulting boats represented the pinnacle of yacht development from 1907-1987 for the highest levels of international sailing competition– the Olympic Games (1908-1920) and the America’s Cup (1958-1987).

Mini 12 or scale down America cup

Discussion in ' Wooden Boat Building and Restoration ' started by bilco , Jan 27, 2005 .

bilco Junior Member

A group of my friends and I are looking at building 3 small keel boats (cold mold) to race on the Tamar river in Tasmania. We have a mixture of skills to get us through the project. But finding a design is proving very very hard. We were hopeing for a mini 12 or 2.4 mr looking boat ,but with a bulb keel. Can anyone offer any advice on where to get line drawings? Is it ok to scale down a large boat? We need a design that is great for racing.  

Raggi_Thor

Raggi_Thor Nav.arch/Designer/Builder

If you scale down a larger boat you will normally increase the width (relatively) search on this fourm for that. Have you looked at http://www.sailingsource.com/24metre/ ?  

PAR

PAR Yacht Designer/Builder

Very rarely does a larger boat scale down well, particularly if the scaling factor will be big, as would be the case of a 12 meter down to a 2 meter. As a result of the changes made you'd likely have a 2 meter that doesn't look at all like the 12 you're trying to copy. Most of the 12 meter designs that you may be interested in will be under the protection of copyright and it would be illegal to copy it, even if the scale was changed. In a boat that size you just be able to fit your body, let alone counter balance a lofty AC rig. So, to answer your questions about scaling down as you hope. NO, it wouldn't be a wise idea, basically she'd just flop over on her side. If you scaled a 3 meter boat down you'd have a chance of success, but still would require a custom effort by a designer. There are thousands of small "sporty" craft designs available. Build one of those, rather then trying to invent a new class which you clearly aren't skilled enough to do yet. Do a search for keel boats and select a design very close to the size you need. Until you gain a great deal more experience, don't change the scale of the design, just build it and have fun. A used International 2.4 meter will run about 5000 euros, a well equipped one 6 to 7000 euros. You'll be hard pressed to build for that and it's a class boat so there will be locals you can race, besides your friends.

I am missing something on this scaling plans up and down. I have had plans scaled up by 6.5 times in 1 pass, and the enlarged blue prints retained the proportions perfectly. Why was I, O K ?  
Richard, I don't think they want to decrease the size of the plans, but in fact the design itself. Lets take a look at L. F. Herreshoff's R-boat Yankee and try to scale her down. She's a little over 37' LOD has a 26' LWL, a beam of about 6'8" and around 9' of draft. Bring this down in scale to 12' LOD (approximately 3x reduction) her LWL is about 8'5", beam 2'3" and draws almost 3' of water. This makes a boat narrower then most canoes with a 3' draft. The same works in reverse, except you end up building a boat with way to much beam for her length. A 22' LOA, 20 LWL, 8' beam centerboard sailor scaled up 3 times would make a 66' LOA, 60' LWL, 24' beam centerboarder and clearly too fat a boat.  
I always forget to scale down the people and " Reynolds numbers and their brethern ".  
There have been a few attempts to use scaling factors to straighten this out, but none work real well. In small increases and decreases, more then just changing the station spacing would permit, the conversion formulas seem to work okay, but when the ratio gets over a certain percentage it goes to hell pretty quickly. The International 2.4 is patterned after the AC boats and does have an AC style sheer, appendage profiles, bow and stern profiles worked into the design, but that's about as close as they can get in this scale. They do look pretty good on post cards (just like snow) It's what construction workers would call a 80 footer (woman walking 80' away) As she got within 70 feet you'd see what was really going on and get back to work . . .

The Norlin is basically a one design and the most popular boat in the 2.4 meter class. But the class is really a developement class so there should be home built plans available. These boats though are not inexpensive to build for their size, they have relatively high weights and the rig is complicated, along with something like 400 lbs. of ballast. For the past few years I've been working on a very simple mini keel boat of around 12 ft. but designed for homebuilders. Unfortionately right now it's incomplete and the prototype never has been built, not yet anyway. This one would though be a bunch less expensive to build. Bill H.

Look a little bit up north, I know they designed at least one good 12 meter up there. Seriously, any decent yacht designer can provide you with a suitable shape. Yokebutt.

It'll be hard to find something race-ready in that size. Tactic's pic there looks about as good as you'll get. You need something that's designed from the outset to be this size. As everyone else has said, scaling a larger boat simply will not work. The CG, CB, metacentric height, centre of sail effort, etc. will all be different and the boat will not perform well at all. If you refine your search, you should find a few more designs like the one in post #11 above that will suit your needs.  
Thee are a few similar production boats avalible.I have searched and searched but have been unable to find plans for anything like this.So I designed my own. I am interested in taking the concpt further,The design i have shown can be built by a amatuer using various strip planking methods. Cheers tactic

There is a very active Mini 12 fleet in the Pacific Northwest, with about 40 or 50 boats between the Royal Victoria Yacht Club (Victoria Canada) and the Seattle Yacht Club. I believe the Seattle Yacht club has purchased a number of Victoria designed Mini 12s in the last year or two. They are being produced by John Booth (Booth Enterprises I think is the business name) in Victoria. They are called Deceptions. I would guess you could contact the Royal Victoria Yacht Club to find out who is the class representative this year. RWL

Illusion Mini 12

  • Description

Seller's Description

Illusion Mini 12 Excellent condition. Re-painted and new Harken blocks added. 2 mains, 2 jibs with furlers, spinnaker. With trailer. Has 200lbs of lead pellet bags for ballast.

Nothing like being laid over close hauled with your head inches from the water in the complete security of a ballasted keel boat.

She has a strong bilge pump in case you take on any water. The only issue is a broken strand on the starboard upper shroud. I still sail with it broken but that shroud will need replaced at some point. In Little Rock, Arkansas or phone 501-551-3325

Rig and Sails

Auxilary power, accomodations, calculations.

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL

Sail Area / Displacement Ratio

A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.

SA/D = SA ÷ (D ÷ 64) 2/3

  • SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
  • D : Displacement in pounds.

Ballast / Displacement Ratio

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Ballast / Displacement * 100

Displacement / Length Ratio

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

  • D: Displacement of the boat in pounds.
  • LWL: Waterline length in feet

Comfort Ratio

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )

  • D: Displacement of the boat in pounds
  • LOA: Length overall in feet
  • Beam: Width of boat at the widest point in feet

Capsize Screening Formula

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.

CSV = Beam ÷ ³√(D / 64)

Spin.: 45 sq. ft. ‘Mini 12’one-design single hander with pedal steering. Similar concept as the 2.4M but somewhat smaller. Ballast can be added or removed from a cavity within keel. Most recent Builder: Advanced Marine Structures www.amstructures.co.uk +44 (0) 1983 200011

Deep seas and tight spaces impede search for 6 missing after yacht sinks off Sicily

mini 12 metre yachts

PORTICELLO, Sicily (AP) — Police divers resumed searching Tuesday for six people believed trapped in the hull of a superyacht that sank in deep seas off Sicily, including British tech magnate Mike Lynch, who was celebrating his recent acquittal on fraud charges with the people who had defended him at trial.

The luxury sailboat, off Porticello near Palermo, was about 50 meters (164 feet) underwater — far deeper than most recreational divers are certified for and a depth that requires special precautions. Recovery crews could only stay for 12-minute shifts, a measure that slowed efforts to reach the cramped inside of the wreck.

Divers tag-teamed the shifts and were using a remote-controlled underwater vehicle, or ROV, to help in the search. They hadn’t been able to access the below-deck cabins because they were blocked by furniture that shifted during the violent storm that struck the vessel early Monday. Rescue crews said they assume the missing six are in those cabins because the storm struck when most would be sleeping, but the teams haven’t verified their presence there through portholes.

The Bayesian, a 56-meter (184-foot) British-flagged yacht, was moored about a kilometer (a half-mile) offshore when a storm rolled in before 4 a.m. Monday. Civil protection officials said they believed the ship was struck by a tornado over the water, known as a waterspout, and sank quickly .

Grainy film from closed-circuit cameras from shore, broadcast on the website of the Giornale di Sicilia, showed the majestic, illuminated 75-meter (246-foot) mast of the Bayesian weathering the storm and then disappearing over the course of a minute.

Fifteen of the 22 people aboard survived, including a mother who reported holding her 1-year-old baby over the waves to save her. One body was recovered, identified by officials as the Antiguan-born on-board chef. The rest of the 10-person crew survived, including the captain whom prosecutors reportedly sought to interview.

The survivors were rescued by a nearby sailboat after getting into a lifeboat.

Lynch, who was once hailed as Britain’s king of technology, was cleared in June of fraud and conspiracy charges in a U.S. federal trial related to Hewlett Packard’s $11 billion takeover of his company, Autonomy Corp. His wife, Angela Bacares, survived the sinking. Hannah Lynch, the couple’s 18-year-old daughter, is reportedly unaccounted for.

Also unaccounted for are Christopher Morvillo, one of Lynch’s lawyers, and his wife, Neda; and Jonathan Bloomer, a chairman at Morgan Stanley International and the former head of the Autonomy audit committee who testified in Lynch’s defense, and his wife.

Karsten Borner, the captain of the Sir Robert Baden Powell, which rescued the survivors, said he was close enough to see the Bayesian as the storm came in.

“A moment later, she was gone,” he said.

“It’s a great, great tragedy,” said Britain’s ambassador to Italy, Edward Llewellyn, who visited Porticello on Tuesday. Britain sent four investigators to the scene, given the disaster involved a British-flagged ship and British citizens were among the missing.

Luca Cari, a spokesman for the rescue teams, said the search was proceeding much more slowly than another big shipwreck in Italy, the 2012 Costa Concordia cruise ship that flipped on its side off Tuscany’s coast, because of the depth of the wreck and the limited space divers have to maneuver.

“That was much simpler. Here everything is more tight,” he said.

The outing was intended at least in part as a celebration of Lynch’s acquittal and a “looking forward to what was coming next,” said Reid Weingarten, a Washington attorney and a member of Lynch’s defense team who was not on the yacht.

“A lot of people went, a lot of people were planning to go and then, of course, this happened,” Weingarten said.

Weingarten worked with Morvillo and said he “was like a brother.”

Aki Hussain, CEO of international insurer Hiscox Group, where Bloomer was chairman, said the company was “deeply shocked and saddened by this tragic event.”

“Our thoughts are with all those affected, in particular our Chair, Jonathan Bloomer, and his wife Judy, who are among the missing, and with their family as they await further news from this terrible situation,” he added.

Among the survivors, the Emslie family was released from Palermo’s pediatric hospital on Tuesday. Charlotte Golunski had reported that she momentarily lost hold of her 1-year-old daughter, Sofia, in the water but then managed to hold her up over the waves until they were both pulled to safety, doctors said.

The father, identified by ANSA news agency as James Emslie, also survived.

“They don’t talk much, primarily because they consider themselves survivors and they don’t understand why they survived given what they went through,” said Dr. Domenico Cipolla, head of the emergency room at Di Cristina pediatric hospital.

Speaking to reporters Tuesday, Cipolla said the parents had been in touch with other survivors, who are being housed at a nearby hotel and were waiting for other family members to arrive in Sicily.

The Bayesian, built in 2008 by the Italian firm Perini Navi, is registered to Revtom Ltd., according to online maritime database Equasis. Bacares, Lynch’s wife, is listed as Revtom’s sole owner, according to corporate registration documents from the Isle of Man.

According to online charter companies, it had been available for charter for 195,000 euros (about $215,000) a week and was notable for its massive 75-meter-tall (246-foot-tall) aluminum mast, one of the tallest in the world.

The coast guard said to date there was no trace of fuel leaks from the wreckage.

In an unrelated event, Lynch’s co-defendant in the Autonomy trial who was also cleared, Stephen Chamberlain, was killed Sunday when he was hit by a car while running in Cambridgeshire, England, said Chamberlain’s lawyer, Gary Lincenberg.
