Published Design Ratios for the Ovni 395
1. Sail Area/Displacement Ratio: 18.3
- 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: 33.0
- Under 40: less stiff, less powerful
- Over 40: stiffer, more powerful
3. Displacement/Length Ratio: 199
- Under 100: Ultralight
- 100 to 200: Light
- 200 to 275: Moderate
- 275 to 350: Heavy
- Over 350: Ultraheavy
4. Comfort Ratio: 27.8
- 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 Ovni 395
1. A Sail Area/Displacement Ratio of 18.3 suggests that the Ovni 395 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 33.0 means that unless the bulk of the ballast is concentrated in a bulb at the foot of her keel, the Ovni 395 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 199, tells us the Ovni 395 is a light-to-moderate displacement sailboat. If she's loaded with too much heavy cruising gear her performance will suffer.
4. Ted Brewer's Comfort Ratio of 27.8 suggests that crew comfort of an Ovni 395 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 1.9 tells us that an Ovni 395 would be a safer choice of sailboat for an ocean passage than one with a CSF of more 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.
