1. Sail Area/Displacement Ratio: 17.7

4. Comfort Ratio: 33.2
5. Capsize Screening Formula: 1.8
1. A Sail Area/Displacement Ratio of 17.7 suggests that the Valiant 47 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 36.7 means that the Valiant 47 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 205, tells us the Valiant 47 is a moderate displacement cruiser, which means she'll carry all your cruising gear without it having a dramatic 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 33.2 suggests that crew comfort of a Valiant 47 in a seaway is similar to what you would associate with the motion of a moderate bluewater cruising boat - a predictable and acceptable motion for most seasoned sailors.
5. The Capsize Screening Formula (CSF) of 1.8 tells us that a Valiant 47 would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.
