Summary Analysis of the Design Ratios for the Dehler 39 CWS

1. A Sail Area/Displacement Ratio of 18.8 suggests that the Dehler 39 CWS will, in the right conditions, approach her maximum hull speed readily and satisfy the sailing performance expectations of most cruising sailors.

2. In the absence of any published ballast weight, we are unable to calculate the Ballast/Displacement Ratio for the Dehler 39 CWS.

3. A Displacement/Length Ratio of 182, tells us the Dehler 39 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 22.2 suggests that crew comfort of a Dehler 39 CWS 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 1.94 indicates that a Dehler 39 CWS would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.

If you are looking for a boat that combines exceptional sailing performance with a modern and comfortable interior, you might want to check out the Dehler 39 CWS sailboat. This boat is the flagship of the new Dehler yacht generation, designed by Van de Stadt and Partners with an unobtrusive design and equipped with proven outstanding technology.

In this article, we will give you an overview of the main features and specifications of this boat, as well as some of the options and variations that are available for different sailing needs and preferences.

The Dehler 39 CWS is a 39-foot (11.9-meter) sailboat that can accommodate up to six people in three cabins. It has a beam of 12.1 feet (3.7 meters) and a draft of 6.4 feet (1.95 meters). It has a displacement of 7.5 tons (6.8 metric tons) and a ballast of 3 tons (2.7 metric tons). It has a sail area of 807 square feet (75 square meters) and a mast height of 54.8 feet (16.7 meters).

One of the distinctive features of this boat is the CWS system, which stands for Central Winch System.

This makes sailing easier and safer, especially for small or inexperienced crews.

The Dehler 39 CWS has a spacious and contemporary interior, with mahogany woodwork and blue upholstery.
