1. Sail Area/Displacement Ratio: 20.9
2. Ballast/Displacement Ratio: 34.5
3. Displacement/Length Ratio: 148
4. Comfort Ratio: 25.9
5. Capsize Screening Formula: 2.0
1. A Sail Area/Displacement Ratio of 20.9 suggests that, in the right hands, the Beneteau Oceanis 50 will have enough performance to leave most other sailboats of similar waterline length well astern.
2. A Ballast/Displacement Ratio of 34.5 would usually mean that the Beneteau Oceanis 50 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 148, tells us the Beneteau Oceanis 50 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 25.9 suggests that crew comfort of a Beneteau Oceanis 50 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 2.0 indicates that a Oceanis 50 would not be the wisest choice of sailboat for ocean passage-making owing to the lower resistance to capsize in strong winds and heavy seas associated with sailboats with a CSF of 2.0 and above.
