Review of C&C 45

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 sandwich construction 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 227.0 liter fresh water capacity.

The C&C 45 is equipped with a fractional rig. A fractional rig has smaller headsails which make tacking easier, which is an advantage for cruisers and racers, of course. The downside is that having the wind from behind often requires a gennaker or a spinnaker for optimal speed.

Fin keel

The C&C 45 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 2.67 - 2.77 meter (8.76 - 9.06 ft) dependent on the load. See immersion rate below.

C&C 45 may be equipped with an inboard Yanmar 4JHE diesel engine at 44 hp (32 kW). Calculated max speed is about 7.1 knots

The fuel tank has a capacity of 76.0 liters (20 US gallons, 16 imperial gallons).

What is Capsize Screening Formula (CSF)?

The capsize screening value for C&C 45 is 2.06, indicating that this boat would not 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 8.4 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 C&C 45 is about 334 kg/cm, alternatively 1872 lbs/inch.
Meaning: if you load 334 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1872 lbs cargo on the boat it will sink 1 inch.

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for C&C 45 is 21.8.

What is L/B (Length Beam Ratio)?

The l/b ratio for C&C 45 is 3.29.

What is a Ballast Ratio?

The ballast ratio for C&C 45 is 51%.

What is Displacement Length Ratio?

The DL-ratio for C&C 45 is 142 which categorizes this boat among 'ultra light racers'.

SA/D (Sail Area Displacement ratio)
Indicates how fast the boat is in light wind:
- Cruising Boats have ratios 10-15
- Cruiser-Racers have ratios 16-20
- Racers have ratios above 20
- High-Performance Racers have ratios above 24
Sail-area/displacement ratio (SA/D ratio): 24.79

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 61m² (656 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.

If you need to renew parts of your running rig and is not quite sure of the dimensions, you may find the estimates computed below useful.
