Review of C&C 46

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 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.

The C&C 46 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 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 is typically equipped with an inboard Perkins diesel engine.

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.

What is L/B (Length Beam Ratio)?

The l/b ratio for C&C 46 is 3.39.

Compared with other similar sailboats it is more spacy than 54% of all other designs. It seems that the designer has chosen a slightly more spacy hull design.

What is a Ballast Ratio?

The ballast ratio for C&C 46 is 43%.

This ballast ratio shows a righting moment that is higher than 85% of all similar sailboat designs. A righting moment (ability to resist heeling) significantly above average.

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

The SA/D for C&C 46 with ISO 8666 reference sail is 16.8, with a 135% genua the SA/D is 20.4.

The SA/D ratio indicates that it is faster than 24% of all similar sailboat designs in light wind.

The C&C 46 has more rig than 24% of all similar sailboats, which indicates that the boat is significantly underrigged.
