1. A Sail Area/Displacement Ratio of 17.4 suggests that the Shearwater 39 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 38.8 means that unless the bulk of the ballast is concentrated in a bulb at the foot of her keel, the Shearwater 39 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 250, tells us the Shearwater 39 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 31.6 suggests that crew comfort of a Shearwater 39 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 Shearwater 39 would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.
