The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season.
The boat is equipped with one cabin, 5 berths and 643.0 liter fresh water capacity.
The Bowman 46 Corsair is 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.
The Bowman 46 Corsair has been built with different keel alternatives.
CentreBoard
One option is a centreboard keel. A centreboard keel is a pivoting lifting keel, allowing to sail both coastal and inland waters.
The boat can enter most marinas as the draft is just about 1.68 - 1.78 meter (5.51 - 5.81 ft) dependent on the load. See immersion rate below.
Full keel
Another option is a long keel. A full keel provide a better directional stability than a similar boat with a fin keel; on the other hand, better directional stability means also that the boat is more difficult to handle in a harbour with less space.
Bowman 46 Corsair can only enter major marinas as the draft is about 2.13 - 2.23 meter (6.99 - 7.29 ft) dependent on the load. See immersion rate below.
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 Bowman 46 Corsair is 1.81, 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 7.6 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 Bowman 46 Corsair is about 257 kg/cm, alternatively 1439 lbs/inch.
Meaning: if you load 257 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 1439 lbs cargo on the boat it will sink 1 inch.

What is SA/D (Sail Area Displacement ratio)?
The SA/D for Bowman 46 Corsair with ISO 8666 reference sail is 14.0, with a 135% genua the SA/D is 16.8.
When buying anti-fouling bottom paint, it's nice to know how much to buy.
The surface of the wet bottom is about 52m2 (559 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.
