Hull

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

Interior

Note: the boat has also been sold to be self-made/-interiored, which means that the quality of each boat may vary.

Keel

The boat can only enter major marinas as the draft is about 2.00 - 2.10 meter (6.56 - 6.86 ft) dependent on the load. See immersion rate below.

Engine

Columbie 45 is typically equipped with an engine.

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 Columbie 45 is 1.89, 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 8.2 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 Columbie 45 is about 336 kg/cm, alternatively 1886 lbs/inch.
Meaning: if you load 336 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1886 lbs cargo on the boat it will sink 1 inch.

46% 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.

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 55m² (592 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.
