Review of Jouët 950

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.

The boat is equipped with 6 berths.

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 keel is made of iron. Many people prefer lead keel in favour of iron. The main argument is that lead is much heavier than iron and a lead keel can therefore be made smaller which again result in less wet surface, i.e. less drag. In fact iron is quite heavy, just 30% less heavy than lead, so the advantage of a lead keel is often overstated.

The boat can enter most marinas as the draft is just about 1.75 - 1.85 meter (5.74 - 6.04 ft) dependent on the load. See immersion rate below.

Jouët 950 is typically equipped with an inboard diesel engine at 18.0 hp (13 kW).

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.

What is Capsize Screening Formula (CSF)?

The capsize screening value for Jouët 950 is 2.20, indicating that this boat would not 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 Jouët 950 is about 212 kg/cm, alternatively 1190 lbs/inch.
Meaning: if you load 212 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1190 lbs cargo on the boat it will sink 1 inch.

What is L/B (Length Beam Ratio)?

The l/b ratio for Jouët 950 is 2.84.

Compared with other similar sailboats it is more spacy than 79% of all other designs. It seems that the designer has chosen a significantly more spacy hull design.

What is a Ballast Ratio?

The ballast ratio for Jouët 950 is 37%.

This ballast ratio shows a righting moment that is higher than 31% of all similar sailboat designs. A righting moment (ability to resist heeling) just below average.

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

The SA/D for Jouët 950 with ISO 8666 reference sail is 17.5, with a 135% genua the SA/D is 21.0.

The SA/D ratio indicates that it is faster than 66% of all similar sailboat designs in light wind.

The Jouët 950 has more rig than 79% of all similar sailboats, which indicates that the boat is significantly overrigged.
