1. Sail Area/Displacement Ratio: 22.8
2. Ballast/Displacement Ratio: 37.6
3. Displacement/Length Ratio: 193
4. Comfort Ratio: 20.9
5. Capsize Screening Formula: 2.1
1. A Sail Area/Displacement Ratio of 22.8 suggests that, in the right hands, the Grand Soleil 343 will have enough performance to leave most other sailboats of similar waterline length well astern.
2. A Ballast/Displacement Ratio of 37.6 means that a sailboat like the Grand Soleil 343 (which doesn't have a stiffness-enhancing bulb keel), is likely to benefit from being reefed early to keep her sailing upright in a moderate breeze.
3. A Displacement/Length Ratio of 193, tells us the Grand Soleil 343 is clearly a light displacement sailboat. If she's loaded with too much heavy cruising gear her performance will suffer to a degree.
4. Ted Brewer's Comfort Ratio of 20.9 suggests that crew comfort of a Grand Soleil 343 in a seaway is similar to what you would associate with the motion of a coastal cruiser with moderate stability, which is not the bequestst of news for anyone prone to seasickness.
5. The Capsize Screening Formula of 2.1 tells us that a Grand Soleil 343 would not be as good a choice of sailboat for ocean passage-making, owing to the increased risk of capsize in strong winds and heavy seas when compared to a sailboat with a CSF of less than 2.0.
