Review of Clipper 42

The deck is made of steel.

The interior is like most other boats made of teak.
The boat is equipped with 9 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.

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.

Clipper 42 is typically equipped with an inboard Volvo Penta engine at 61.0 hp (45 kW), which gives a max speed about 7.7 knots.

The transmission is a shaft drive. A shaft drive will in the long run require less maintenence than other types of drive e.g. a sail drive.

The fuel tank which is made of steel has a capacity of 200.0 liters (52 US gallons, 43 imperial gallons).

What is Capsize Screening Formula (CSF)?

The capsize screening value for Clipper 42 is 1.78, 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 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 Clipper 42 is about 304 kg/cm, alternatively 1703 lbs/inch.
Meaning: if you load 304 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1703 lbs cargo on the boat it will sink 1 inch.

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for Clipper 42 is 29.2.

Comparing this ratio with similar sailboats show that it is more comfortable than 42% of all similar sailboat designs. This comfort value is just below average.

What is L/B (Length Beam Ratio)?

The l/b ratio for Clipper 42 is 3.42.

Compared with other similar sailboats it is slimmer than 62% of all other designs. It seems that the designer has chosen a slightly more speedy hull design.

What is Displacement Length Ratio?

The DL-ratio for Clipper 42 is 163 which categorizes this boat among 'light racers'.

85% of all similar sailboat designs are categorized as heavier. A light displacement requires less sailarea and has higher accellerations.
