Published Design Ratios for the Beneteau First 375
1. Sail Area/Displacement Ratio: 16.8
- 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: 34.3
- Under 40: less stiff, less powerful
- Over 40: stiffer, more powerful
3. Displacement/Length Ratio: 189
- Under 100: Ultralight
- 100 to 200: Light
- 200 to 275: Moderate
- 275 to 350: Heavy
- Over 350: Ultraheavy
4. Comfort Ratio: 24.5
- 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: 1.9
- 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 Beneteau First 375
1. A Sail Area/Displacement Ratio of 16.8 suggests that the Beneteau First 375 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 34.3 means that a sailboat like the Beneteau First 375 (which doesn't have a stiffness-enhancing bulb keel), is likely to benefit from being reefed early to keep her sailing upright in a moderate breeze.
3. A Displacement/Length Ratio of 189 tells us the Beneteau First 375 is 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 24.5 suggests that crew comfort of a Beneteau First 375 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 of 1.9 tells us that a Beneteau First 375 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.

Medium sized cruising yachts like these are often the sailboat of choice for short-handed crews, and if properly equipped and maintained, will take long offshore voyages in their stride.
