Published Design Ratios for the Hunter 40.5 Legend
1. Sail Area/Displacement Ratio: 16.6
- 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: 35.0
- Under 40: less stiff, less powerful
- Over 40: stiffer, more powerful
3. Displacement/Length Ratio: 202
- Under 100: Ultralight
- 100 to 200: Light
- 200 to 275: Moderate
- 275 to 350: Heavy
- Over 350: Ultraheavy
4. Comfort Ratio: 29.3
- 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 Hunter 40.5 Legend
1. A Sail Area/Displacement Ratio of 16.6 suggests that the Hunter 40.5 Legend 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 35.0 means that the Hunter 40.5 Legend 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.
3. A Displacement/Length Ratio of 202, tells us the Hunter 40.5 Legend is a moderate displacement cruiser, which means she'll carry a reasonable amount of cruising gear without it having too much of an 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 29.3 suggests that crew comfort of a Hunter 40.5 Legend 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 (CSF) of 1.8 tells us that a Hunter 40.5 Legend would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.
