1. Sail Area/Displacement Ratio: 16.8
2. Ballast/Displacement Ratio: 32.0
3. Displacement/Length Ratio: 153
4. Comfort Ratio: 22.9
5. Capsize Screening Formula: 2.0
1. A Sail Area/Displacement Ratio of 16.8 suggests that the Beneteau 411 will, in the right conditions, approach her maximum hull speed readily and satisfy the sailing performance expectations of most cruising sailors.
2. A Ballast/Displacement Ratio of 32.0 would usually mean that the Beneteau 411 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 153, tells us the Beneteau 411 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 22.9 suggests that crew comfort of a Beneteau 411 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 tells us that a Beneteau 411 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.
