Published Design Ratios for the Hunter 39
1. Sail Area/Displacement Ratio: 23.1
- 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: 31.0
- Under 40: less stiff, less powerful
- Over 40: stiffer, more powerful
3. Displacement/Length Ratio: 194
- Under 100: Ultralight
- 100 to 200: Light
- 200 to 275: Moderate
- 275 to 350: Heavy
- Over 350: Ultraheavy
4. Comfort Ratio: 25.6
- 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: 2.0
- 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 39
1. A Sail Area/Displacement Ratio of 23.1 suggests that, in the right hands, the Hunter 39 will have enough performance to leave most other sailboats of similar waterline length well astern.
2. A Ballast/Displacement Ratio of 31.0 means that a sailboat like the Hunter 39 (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 194, tells us the Hunter 39 is clearly a light displacement sailboat. If she's loaded with too much heavy cruising gear her performance will suffer dramatically.
4. Ted Brewer's Comfort Ratio of 25.6 suggests that crew comfort of a Hunter 39 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 2.0 indicates that a Hunter 39 would not be the wisest choice of sailboat for ocean passage-making owing to the lower resistance to capsize in strong winds and heavy seas that is associated with similar sailboats with a CSF of 2.0 and above.

Large, well-equipped cruising yachts of this size can cross oceans in relative comfort and speed, but you'll need deep pockets to operate and maintain them.
