1. A Sail Area/Displacement Ratio of 19.6 suggests that the Dehler 35 CWS 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 40.0 means that the Dehler 35 CWS will initially stand up reasonably well to her canvas in a moderate breeze, but she's likely to benefit from a reef in the main to avoid heeling uncomfortably in a gust.

3. A Displacement/Length Ratio of 190, tells us the Dehler 35 CWS 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 22.3 suggests that crew comfort of a Dehler 35 CWS 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 (CSF) of 1.9 indicates that a Dehler 35 CWS would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.
