1. Sail Area/Displacement Ratio: 22.0
2. Ballast/Displacement Ratio: 42.4
3. Displacement/Length Ratio: 211
4. Comfort Ratio: 23.3
5. Capsize Screening Formula: 2.1
1. A Sail Area/Displacement Ratio of 22.0 suggests that, in the right hands, the Ovni 43 will have enough performance to leave most other sailboats of similar waterline length well astern.
2. A Ballast/Displacement Ratio of 42.4 means that the Ovni 43 will stand up well to her canvas in a blow, helping her to power through the waves.
3. A Displacement/Length Ratio of 211, tells us the Ovni 43 is a moderate displacement cruiser, which means she'll carry all your cruising gear without it having a dramatic effect on her performance. Most of today's sailboats intended for offshore cruising fall into this displacement category.
4. Ted Brewer's Comfort Ratio of 23.3 suggests that crew comfort of a Ovni 43 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 xxxx would not be a good 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.
