Hull

The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season. And outside the sailing season, just bottom cleaning and perhaps anti-fouling painting once a year - a few hours of work, that's all.
Unfortunately, the hull is not a double hull which affects the indoor climate. Especially if the water is considerable colder than the cabin, then one might expect condense water in the cabin.

Interior

The interior is like many other boats made of mahogany. Mahogany belongs to the hardwood species, known for being water-repellent and resistant to decay. It has an attractive wood grain and holds wood polish and varnish well.
The boat is equipped with 5 berths, a galley and toilet facility.

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

Rig

The C&C 30 E 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.

Engine

C&C 30 E may be equipped with an inboard Volvo Penta MD7A diesel engine at 13 hp (9 kW). Calculated max speed is about 4.5 knots

The transmission is a saildrive.

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 C&C 30 E is 2.05, indicating that this boat would not 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 6.5 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 C&C 30 E is about 152 kg/cm, alternatively 856 lbs/inch.
Meaning: if you load 152 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 856 lbs cargo on the boat it will sink 1 inch.
