1. Sail Area/Displacement Ratio: 20.9
2. Ballast/Displacement Ratio: 26.5
3. Displacement/Length Ratio: 152
4. Comfort Ratio: 23.8
5. Capsize Screening Formula: 2.1
1. A Sail Area/Displacement Ratio of 20.9 suggests that, in the right hands, the Dufour 460 Grand Large will have enough performance to leave most other sailboats of similar waterline length well astern.
2. A Ballast/Displacement Ratio of 26.5 would usually mean that the Dufour 460 Grand Large 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 152 tells us the Dufour 460 Grand Large 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 23.8 suggests that crew comfort of a Dufour 460 Grand Large 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 20.1 tells us that a Dufour 460 Grand Large 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.
