1. Sail Area/Displacement Ratio: 21.7

3. Displacement/Length Ratio: 157
4. Comfort Ratio: 27.4
5. Capsize Screening Formula: 1.8
1. A Sail Area/Displacement Ratio of 21.7 suggests that, in the right hands, the Dehler 45 will have enough performance to leave most other sailboats of similar waterline length well astern.
2. A Ballast/Displacement Ratio of 36.4 would usually mean that the Dehler 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 157 tells us the Dehler 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 27.4 suggests that crew comfort of a Dehler 45 in a seaway is similar to what you would associate with the motion of a coastal cruiser with moderate stability, which is not the best of news for anyone prone to seasickness.
5. The Capsize Screening Formula (CSF) of 1.8 indicates that a Dehler 45 would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.
