Published Design Ratios for the Grande Soleil 46
1. Sail Area/Displacement Ratio: 22.3
- 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: 41.5
- Under 40: less stiff, less powerful
- Over 40: stiffer, more powerful
3. Displacement/Length Ratio: 229
- Under 100: Ultralight
- 100 to 200: Light
- 200 to 275: Moderate
- 275 to 350: Heavy
- Over 350: Ultraheavy
4. Comfort Ratio: 33.2
- 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: 1.8
- 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 Grande Soleil 46
1. A Sail Area/Displacement Ratio of 22.3 suggests that, in the right hands, the Grande Soleil 46 will have enough performance to leave most other sailboats of similar waterline length well astern.
2. A Ballast/Displacement Ratio of 41.5 means that the Grande Soleil 46 will stand up well to her canvas in a blow, helping her to power through the waves.
3. A Displacement/Length Ratio of 229, tells us the Grande Soleil 46 is a moderate displacement cruiser, which means she'll carry all your cruising gear without it having a dramatic effect on her performance. Most of today's sailboats intended for offshore cruising fall into this displacement category.
4. Ted Brewer's Comfort Ratio of 33.2 suggests that crew comfort of a Grande Soleil 46 in a seaway is similar to what you would associate with the motion of a moderate bluewater cruising boat - a predictable and acceptable motion for most seasoned sailors.
5. The Capsize Screening Formula (CSF) of 1.8 indicates that a Grande Soleil 46 would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.
