Published Design Ratios for the Beneteau First 28
Sail Area/Displacement Ratio: 16.5
- Less 16 would be considered under-powered;
- 16 to 20 would indicate reasonably good performance;
- Over 20 suggests relatively high performance.
Ballast/Displacement Ratio: 37.1
- Under 40: less stiff, less powerful
- Over 40: stiffer, more powerful
Displacement/Length Ratio: 186
- Under 100: Ultralight
- 100 to 200: Light
- 200 to 275: Moderate
- 275 to 350: Heavy
- Over 350: Ultraheavy
Comfort Ratio: 17.2
- 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
Capsize Screening Formula: 2.2
- Under 2.0 (the lower the better): Better suited for ocean passages
- Over 2.0: Less suited for ocean passages

Summary Analysis of Published Design Ratios for the Beneteau First 28
A Sail Area/Displacement Ratio of 16.5 suggests that the Beneteau First 28 will approach her maximum hull speed readily and satisfy the sailing performance expectations of most cruising sailors.
A Ballast/Displacement Ratio of 37.1 means that the Beneteau First 28 will have a tendency to heel excessively in a gust, and she'll need to be reefed early to keep her sailing upright in a moderate breeze.
A Displacement/Length Ratio of 186, tells us she's clearly a light displacement sailboat. If she's loaded with too much heavy cruising gear her performance will suffer dramatically.
Ted Brewer's Comfort Ratio of 17.2 suggests that crew comfort in a seaway is akin to the motion of a lightweight racing boat. Upwind the Beneteau First 28 will be tender and will slam enough to shake your fillings out with a lively motion that most cruising sailors have no desire to get used to.
Her Capsize Screening Formula of 2.2 tells us that the Beneteau First 28 would not be a good 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.
