Review of Compis 28

Basic specs..

The Compis 28 is equipped with a fin keel. The fin keel is the most common keel and provides splendid manoeuvrability. The downside is that it has less directional stability than a long keel.

The keel is made of iron. Many people prefer lead keel in favour of iron. The main argument is that lead is much heavier than iron and a lead keel can therefore be made smaller which again result in less wet surface, i.e. less drag. In fact iron is quite heavy, just 30% less heavy than lead, so the advantage of a lead keel is often overstated. As the surface of a fin type keel is just a fraction of the total wet surface, the difference between an iron keel and a lead keel can in reality be ignored for cruising yachts.

Compis 28 can enter most marinas as the draft is just about 1.51 - 1.61 meter (4.95 - 5.25 ft) dependent on the load. See immersion rate below.

The boat is typically equipped with an inboard Yanmar YSE diesel engine at 8.0 hp (5 kW), which gives a max speed about 3.9 knots.

The transmission is a shaft drive. A shaft drive will in the long run require less maintenence than other types of drive e.g. a sail drive.

The fuel tank has a capacity of 22 liters (5 US gallons, 4 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 Compis 28 is 1.96, 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 6.5 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 Compis 28 is about 135 kg/cm, alternatively 756 lbs/inch. Meaning: if you load 135 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 756 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.

Compass 28 is a 28 ′ 2 ″ / 8.6 m monohull sailboat designed by Gunter Heuchmer & Don Lees and built by Compass Yachts Ltd. between 1970 and 1981.

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)

A development of the earlier NORTHERNER 28 (1966). The deck and coach roof was re-designed by John Duncanson. The COMPASS 28 and COMPASS 29 are among the most popular boats of this size in Australia.

How long will feckless Joe Biden ignore the grave threat of sharks and electric boats?

Does biden even care about patriotic americans like us, the ones who might one day be forced to choose between boat-battery electrocution or death by shark.

Thank God for MY PRESIDENT, Donald J. Trump, the one presidential candidate with courage enough to confront the greatest twin threats of our time: sharks and electric boat batteries.

At a recent rally, Trump brought up the dilemma that’s keeping so many Americans who ride through shark-infested waters in battery-powered boats awake at night: “What would happen if the boat sank from its weight, and you’re in the boat and you have this tremendously powerful battery, and the battery is now underwater and there’s a shark that’s approximately 10 yards over there ?”

It’s truly every electric-boat-using parent’s worst nightmare, assuming they don’t understand how boat batteries work and don't question why the shark that’s 10 yards over there wouldn’t also be getting electrocuted.

“Do I get electrocuted if the boat is sinking, water goes over the battery, the boat is sinking?” Trump smartly asked . “Do I stay on top of the boat and get electrocuted, or do I jump over by the shark and not get electrocuted?”

Unlike Trump, Biden doesn't care if you get eaten by a shark

These are not the kind of sensible, America-loving questions you hear from Sleepy Joe Biden. Does he even care about patriotic Americans like us, the ones who might one day be forced to choose between boat-battery electrocution or death by shark?

I doubt he cares at all. He’s too busy being both dementia-addled AND the devious mastermind of a global crime family while also turning our country into a banana republic by allowing the justice system to use a "jury" to find Trump “guilty” of “crimes.”

Obviously Trump is Jesus: Marjorie Taylor Greene compares Trump to Jesus. Which Bible is she reading?

No, you won’t hear one word from Biden about sharks or large boat batteries.

He’s either too busy being totally out of it due to severe mental decline OR carefully plotting an elaborate scheme to get his son convicted on federal gun charges so people think that the justice system is legitimate and that Trump’s recent 34-count conviction on New York felony charges wasn’t actually rigged.

NICE TRY, SLEEPY JOE!

Maybe for a change you could give a damn about the American people by making sure they aren’t dying of ocean electrocution or in the razor-toothed mouths of presumably electrocution-proof sharks!

Trump will surely protect us from battery electrocution and sharks

At the same rally where Trump addressed our nation’s shark/battery crisis – a speech many are saying was as good as, if not better than, President John F. Kennedy’s 1961 inaugural address – the man who made MAGA noted : “By the way, a lot of shark attacks lately, do you notice that? A lot of sharks. I watched some guys justifying it today. ‘Well, they weren’t really that angry, they bit off the young lady’s leg because of the fact that they were not hungry but they misunderstood who she was.’ These people are crazy. He said there’s no problem with sharks they just didn’t really understand a young woman swimming now who really got decimated and a lot of other people too, a lot of shark attacks.”

Indeed. All these shark attacks , combined with what I assume are innumerable instances of battery-powered boats sinking near sharks, have created a national catastrophe Biden is choosing to ignore.

Questions abound when it comes to sinking electric-powered boats

There are so many questions. Why are the boats sinking, and why, as Trump mentioned, is there always a shark “approximately 10 yards” away?

Are these sharks working for the Democratic National Committee? Is the Biden Crime Family having communist China manufacture the boats that keep sinking under the weight of these batteries?

Hunter Biden convicted: Hunter Biden guilty verdict proves Trump's trial wasn't 'rigged'

And why does the electrical current stop mattering if the person jumps over by the shark?

Wouldn’t the boater who leaps overboard get both electrocuted AND eaten by the shark that, for some reason, is wholly unfazed by any electric current?

Another Biden term means certain death for electric-boat owners

And why have we never heard of the presumably thousands of people who are being electrocuted by boat batteries? Is this a cover-up by the fake news media?

With shark-lover Biden in office, we’ll surely never know. And unless Trump gets elected this fall, more and more Americans will have to answer the impossible question posed by the man we Republicans think should be leader of the free world: “Do I stay on top of the boat and get electrocuted, or do I jump over by the shark and not get electrocuted?”

Vote accordingly, folks. Otherwise, the sharks and the batteries win.

Compis 28 with Yanmar YSB8 8hp motor for only 2300 euro!

Friends, take a look at Compis 28 with Yanmar YSB8 8hp motor for only 2300 euro!

Location: Sweden

Length: 8.56 meters Width: 2.84 meters Draft: 1.51 meters Berths: 5 Galley (kitchen): available Toilet: available

The motor Yanmar YSB8 powered 8 hp is original. It is low-powered in my opinion, in some weather you can be lacking power though in the old days it was widely thought that it was enough.

The plastic looks good (just wash it). The set of sails includes a mainsail and a jib with the furler.

There’s a swim platform on the stern, an autopilot Raymarine ST1000, a GPS navigator Raymarine, a solar panel, new electric wiring, a heater Wallas, a stove, a fridge, a full set of mooring equipment.

The seller says that this sailboat is now on the shore but there’s no problem to float it off. There are also some disadvantages: a starter battery needs to be replaced and a sprayhood needs some repair (this isn’t expensive).

The owner gives a lot of documents and receipts with this sailboat so you will easily find out the history of repairs and maintenance.

A 28 feet sailboat with an inboard motor and big amount of expensive equipment for only 2300 euro. It’s a really good offer!
