Published Design Ratios for the Jeanneau Sun Legende 41
1. Sail Area/Displacement Ratio: 18.2
- Less than 16 would be considered under-powered;
- 16 to 20 would indicate reasonably good performance;
- Over 20 suggests relatively high performance.
2. Ballast/Displacement Ratio: 42.5
- Under 40: less stiff, less powerful
- Over 40: stiffer, more powerful
3. Displacement/Length Ratio: 205
- Under 100: Ultralight
- 100 to 200: Light
- 200 to 275: Moderate
- 275 to 350: Heavy
- Over 350: Ultraheavy
4. Comfort Ratio: 23.4
- Under 20 indicates a lightweight racing boat
- 20 to 30 indicates a coastal cruiser
- 30 to 40 indicates a moderate offshore cruising boat
- 40 to 50 indicates a heavy offshore boat
- Over 50 indicates an extremely heavy offshore boat
5. Capsize Screening Formula: 2.1
- Under 2.0 (the lower the better): Better suited for ocean passages
- Over 2.0: Less suited for ocean passages

Summary Analysis of the Design Ratios for the Jeanneau Sun Legende 41
1. A Sail Area/Displacement Ratio of 18.2 suggests that the Jeanneau Sun Legende 41 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 42.5 means that the Jeanneau Sun Legende 41 will stand up well to her canvas in a blow, helping her to power through the waves.
3. A Displacement/Length Ratio of 205, tells us the Jeanneau Sun Legende 41 is a light-to-moderate 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 23.4 suggests that crew comfort of a Jeanneau Sun Legende 41 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 2.1 tells us that a Jeanneau Sun Legende 41 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.

'Endeavour' is a very special Tartan 34C, as you will see from the cutter rig modification, Ratcliffe wind vane auxiliary rudder self-steering, SSB radio, radar, and more.

The broad beam, large cockpit and spacious salon of the Dudley Dix Hout Bay 40 make for a very comfortable sailboat to live aboard and sail.
