Review of Columbia 57


Basic specs.

sail specifications
The Columbia 57 aka Sailcrafter 57 is a large sailboat designed by the American maritime architect William H. Tripp, Jr. in the late sixties. Only a few boats have been produced. The Columbia 57 is built by the American yard Columbia Yachts.

Here we would have liked to show you nice photos of the Columbia 57.

Hull
The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season.

Rig
The boat equipped 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.

Keel

The Columbia 57 is equipped with a fin keel. A boat with a fin keel is more manoeuvrable but has less directional stability than a similar boat with a long keel.

The keel is made of lead. Compared with iron, lead has the advantage of being 44% heavier, which allows a smaller keel and hence less water resistance and higher speed.

The boat can only enter major marinas as the draft is about 2.44 - 2.54 meter (8.01 - 8.31 ft) dependent on the load. See immersion rate below.


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.

Stability and Safety

What is Capsize Screening Formula (CSF)?

The capsize screening value for Columbia 57 is 1.46, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.


Theoretical Maximum Hull Speed

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 8.5 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.


Immersion rate

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Columbia 57 is about 328 kg/cm, alternatively 1842 lbs/inch.
Meaning: if you load 328 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1842 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.

L/B (Length Beam Ratio)

What is L/B (Length Beam Ratio)?

The l/b ratio for Columbia 57 is 4.35.

Wide Slim 100% 0 50 100
Compared with other similar sailboats it is slimmer than 100% of all other designs. It seems that the designer has chosen a significantly more speedy hull design. This type of design is also referred to as 'needle'.


Ballast Ratio

What is a Ballast Ratio?

The ballast ratio for Columbia 57 is 49%.

Low High 96% 0 50 100
This ballast ratio shows a righting moment that is higher than 96% of all similar sailboat designs. A righting moment (ability to resist heeling) significantly above average.


D/L (Displacement Length Ratio)

What is Displacement Length Ratio?

The DL-ratio for Columbia 57 is 298 which categorizes this boat among 'medium weight cruisers'.

Heavy Light 15% 0 50 100
15% of all similar sailboat designs are categorized as heavier. A heavy displacement combined with smaller water plane area has lower acceleration and is more comfortable.


SA/D (Sail Area Displacement ratio)

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

The SA/D for Columbia 57 with ISO 8666 reference sail is 16.4, with a 135% genua the SA/D is 19.4.

Low High 46% 0 50 100
The SA/D ratio indicates that it is faster than 46% of all similar sailboat designs in light wind.

Maintenance

Bottom Paint

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 60m2 (645 ft2).
Based on this, your favourite maritime shop can tell you the quantity you need.

Note: If you use a paint roller you will need more paint than if you use a paintbrush.
