Summary Analysis of the Design Ratios for the Jeanneau Sun Odyssey 45

1. A Sail Area/Displacement Ratio of 22.3 suggests that, in the right hands, the Jeanneau Sun Odyssey 45 will have enough performance to leave most other sailboats of similar waterline length well astern. 

2. A Ballast/Displacement Ratio of 29.8 would usually mean that the Jeanneau Sun Odyssey 45 would have a tendency to heel uncomfortably in a gust, and need to be reefed early to keep her sailing upright in a moderate breeze.

However, as she has much of her ballast concentrated in a bulb at the foot of her keel, she's likely to be considerably stiffer than her published Ballast/Displacement Ratio might suggest.

3. A Displacement/Length Ratio of 176, tells us the Jeanneau Sun Odyssey 45 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 24.2 suggests that crew comfort of a Jeanneau Sun Odyssey 45 in a seaway is similar to what you would associate with the motion of a coastal cruiser with moderate stability, which is not encouraging news for anyone prone to seasickness. 

5. The Capsize Screening Formula of 2.1 tells us that a Jeanneau Sun Odyssey 45 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.
