The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season.
The hull is a double hull which improves the indoor climate. Especially when the water is colder than the air in the cabin, then the double hull insulates against cold water and reduce the condense water in the cabin.
The boat is equipped with 10 berths, a galley and toilet facility.
The C&C 46 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.
Fin keel
The C&C 46 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 full 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 2.29 - 2.39 meter (7.51 - 7.81 ft) dependent on the load. See immersion rate below.
C&C 46 may be equipped with an inboard Perkins diesel 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.
What is Capsize Screening Formula (CSF)?
The capsize screening value for C&C 46 is 1.83, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.
The immersion rate is defined as the weight required to sink the boat a certain level.
The immersion rate for C&C 46 is about 394 kg/cm, alternatively 2209 lbs/inch.
Meaning: if you load 394 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 2209 lbs cargo on the boat it will sink 1 inch.
