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)

553 built including the later COLUMBIA 28 MK II. Similar to CORONADO 28. Sold later in varying stages of completion as the SAILCRAFTER 28.

Crusing in a Columbia 28

  • Add to quote

I OWN A COLUMBIA 28, AND I AM INTERESTED IN CRUISING ON A FULL TIME BASIS. IT HAS ALOT OF ROOM. BUT IS IT SEA WORTHY FOR BLUEWATER CRUISING? I HAVE READ ALOT OF GOOD COMMENTS ON OTHER TOPICS. PLEASE ALL RESPOND TO MINE.  

columbia 28 sailboat data

Columbia built a number of different 28 footers. What year is yours? In a general sense, in their day, Columbias were middle of the road boats, far from being the best built boats but also not the worst. Their fiberglass work was generally considered pretty mediocre and many of their systems were pretty poorly done. Still in all the boats typically were designed by respected designers and sailed reasonably well. They are now coming up on 20-30 or more years in age and are probably becoming pretty tired. Off hand, depending on which 28 you have, I would be concerned about the hull to deck joint, fatigue at high stress areas of the hull, the centerboard, port lights(which were quite large and plastic), bulkhead tabbing, keel bolts, mast step structure, standing and running rigging, deck hardware, electrical and plumbing systems. These are posible problem on any older boat and Columbias were not exactly the best built older boat. Respectfully Jeff  

JEFF H, THANKS FOR THE IMFORMATION. MINE IS A 1967. I AM THE 3RD OWNER AS . I PURCHASED IT LAST YEAR. THE 2 ND OWNER BEFORE ME PURCHASED IT 3 YEARS AGO. THE PREVIOUS OWNERS KEPT IT IN IMMACULATE CONDITION. THE INTERIOR LOOKS AS IT DID NEW. VERY WELL KEPT FOR A 34 YEAR OLD BOAT. THERE ARE NO SIGNS OF LEAKAGE ON THE INTERIOR. CAN YOU GIVE ME A LIST OF CHECKPOINTS TO FOLLOW TRHOUGH. TO INSPECT FOR ANY APPARENT DAMAGES. THE EXTERIOR GELCOAT IS WORN . I AM LOOKING AT A REPAINT ON THE EXTERIOR.AND I WAS GOING TO REPLACE THE STANDING AND RUNNING RIGGING AS A PRECAUTION.NO CENTERBOARD. JUST KEEL. KEEL BOLTS APPEAR TO BE OK A LITTLE SURFACE RUST ONLY.  

You need to have a thorough survey. Keel bolts have a 25 to 35 year lifespan and typically rust out in the portion of the bolt that passes through the fiberglass and not in the bilge. I think that the best that I can do is the list that I already mentioned. Good luck Jeff

Review of Columbia 28 Mk II

Basic specs..

The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season. And outside the sailing season, just bottom cleaning and perhaps anti-fouling painting once a year - a few hours of work, that's all.

The boat is equipped with 68.0 liter fresh water capacity.

The Columbia 28 Mk II is built with a masthead rig. The advantage of a masthead rig is its simplicity and the fact that a given sail area - compared with a fractional rig - can be carried lower and thus with less heeling moment.

The Columbia 28 Mk II is built with a fin keel. A boat with a fin keel is more manoeuvrable but has less directional stability than a similar boat with a full keel.

The boat can enter even shallow marinas as the draft is just about 1.46 - 1.56 meter (4.79 - 5.09 ft) dependent on the load. See immersion rate below.

Columbia 28 Mk II may be equipped with an inboard Universal Atomic 4 gasoline engine at 30 hp (22 kW). Calculated max speed is about 7.3 knots

The fuel tank has a capacity of 45.0 liters (11 US gallons, 9 imperial gallons).

Sailing characteristics

This section covers widely used rules of thumb to describe the sailing characteristics. Please note that even though the calculations are correct, the interpretation of the results might not be valid for extreme boats.

What is Capsize Screening Formula (CSF)?

The capsize screening value for Columbia 28 Mk II is 1.79, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 6.3 knots. The term "Theoretical Maximum Hull Speed" is widely used even though a boat can sail faster. The term shall be interpreted as above the theoretical speed a great additional power is necessary for a small gain in speed.

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Columbia 28 Mk II is about 115 kg/cm, alternatively 646 lbs/inch. Meaning: if you load 115 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 646 lbs cargo on the boat it will sink 1 inch.

Sailing statistics

This section is statistical comparison with similar boats of the same category. The basis of the following statistical computations is our unique database with more than 26,000 different boat types and 350,000 data points.

What is Motion Comfort Ratio (MCR)?

What is L/B (Length Beam Ratio)?

What is a Ballast Ratio?

What is Displacement Length Ratio?

What is SA/D (Sail Area Displacement ratio)?

Maintenance

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 20m 2 (215 ft 2 ). Based on this, your favourite maritime shop can tell you the quantity you need.

Thanks.

Boat: 1976 Sabre 28-2
. The 28 was a fin keeler with external to flange. Not a great fan of this type of construction because it leaves that vital joint hanging out in the where it can be easily damaged. The rubber strake that they hide the joint with deteriorates with age and seems to be hard to replace cosmetically. The new just seemed to be more cheaply built. Also, the later boats were not as good looking as the earlier and S&S designs and many were downright ugly.

I'd look for a 29 if I was going to buy a of that size from that era. It's a good looking S&S design that was well built and well. A I'd take almost anywhere if I could squeeze myself and into it.

I sailed aboard a Columbia 28 from to Lanai and then to the windward side (Hilo) on Island in one and it was surprisingly strong.
If you can find one in good shape and well maintained I think it would make a good coastal cruiser and maybe even do more depending on your sailing experience. I'd look for one with a vs the Atomic 4 gas .

and if well cared for should last practically forever. Mine has an inboard well in the for an outboard to drop into but thats been sealed and the outboard mounted on the transom. Like the above poster i have an 8 hp and its more than adequate, at 30 pct throttle it will gradually slip through the at 3-4 kts, sipping . Doubling the throttle to 60 pct only bumps it up half a and is a waste of gas.

In that era columbia was thousands of boats so the thing to watch for is how far along in the design the one you are looking at was made. Ie if they started that model in 67 then a 69 would be a great boat, but a 75 would have a lot of defects. As long as your boat was made fairly early on then the would still be good and not have many glassed over defects that would effect performance.

For example my mk 2 is a 72, they started the model in 68. Mine like a tank points upwind great and tracks awesome, grabs even at 50 deg heel. Another poster on here bought a brand new one off the line in 77 and found that the didnt grab at high heel, it would track to leeward when sailing into the and he had problems with the to join leaking. Same boat model. Eventually the got so bad that they altered it and removed some of the finer design elements and made the col 26 k, theres one in the slip behind me and it looks like a peice of junk, much lower quality.

Point im trying to make is the fellow with the 77 and my boat were the same but later in the series defects gave him a vastly different boat in handling than mine 5 years older.

Also another thing to look at is the hull . Bill tripp made great boats some of the other designers that columbia used not so much. Look up the and see what people thought of their designs.

Hope this helps.

Also on the outboard/inboard topic the inboards are much more expensive to fixx, find for or replace. Ie if you get a 1969 boat with the original you are relying on a that is 40 years old. Not unlike with a car engine thats 40 years old you could end up on a quest for or a technician spending a lot longer to fumble around and figure out whats wrong. Hours with the = $$ and if you cant find it you could end up having to retrofit in a new engine.

coast and to all the Channel Islands. I lived aboard for more than 5 years and had thousands of hours operating time on her which I used for sea experience to obtain my 100 ton masters in 1984.

Take it from me, the old "Artemisia" was built like a tank. Never had any structural, cosmetic or problems-i.e. no , no , no anything! She sailed extremely well on a broad reach, but was also fairly fast close hauled. We once sailed her from Los Angeles Harbor's Angels Gate Light to Long Point, , on a beam reach, in just over 3 hours-that's averaging about 7.5-8.0 kts!

I was concerned about the external lead ballast since the were regular and rusted where standing in the kept them wet. I put new on them. However, there were never any separation problems with the ballast or the rudder, even after I grounded her a couple of times at .

She had the original, reliable Atomic 4 inboard, which also never failed me, and only required periodic tune ups and changes. I replaced the original system with a new plastic tank unit which worked great. The old unit was clogged and caused water to back up into the which damaged the valves. So, I did an easy valve job on her, in the boat, and off we went again.

I can't tell you how many wonderful times and great sails I had on the old girl. I single- handed her most of the time and she was a joy to . I would recommend that an extender be attached to the tiller and that you have an automatic pilot. Since she is a fin , spade rudder design, she will not hold a point of sail very long if you release the tiller to take a leak, etc. The rudder is hung in space with a steel post, which can loosen up in the tube over time. Simple fix by replacing the gaskets. Also, I had to beef up the tiller bracket for additional strength.

Overall, she was a great vessel, and roomy enough inside to be a comfortable for two large adults. We would provision with ample stores, water and , and take her cruising for 1-2 weeks at a time.

Overall, I would highly recommend a Columbia 28, MK II, especially now that you can pick one up for as low as $2,000.00. I paid $15,000 in 1980, and never regretted the decision-it was worth every penny.

I still miss her and dream more about her than any animate mistress that has crossed my path!

  1. COLUMBIA 28 - sailboatdata

    A boat with a BN of 1.6 or greater is a boat that will be reefed often in offshore cruising. Derek Harvey, “Multihulls for Cruising and Racing”, International Marine, Camden, Maine, 1991, states that a BN of 1 is generally accepted as the dividing line between so-called slow and fast multihulls.
