1. A Sail Area/Displacement Ratio of just 15.9 suggests that the Valiant 40 will need a stiff breeze to get her going. In light conditions, unless you've got plenty of time on your hands, motor-sailing may be the way to go.
2. A Ballast/Displacement Ratio of 35.7 means that unless the bulk of the ballast is concentrated in a bulb at the foot of her keel, the Valiant 40 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 267, tells us the Valiant 40 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 35.8 suggests that crew comfort of a Valiant 40 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 1.7 tells us that a Valiant 40 would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.
