1. The Sail Area/Displacement Ratio for the Colvic Countess 37 has not been published.
2. A Ballast/Displacement Ratio of 40.5 means that the Colvic Countess 37 will initially stand up reasonably well to her canvas in a moderate breeze, but she'll need a reef in the main to avoid heeling excessively in a gust.
3. A Displacement/Length Ratio of 330, tells us the Colvic Countess 37 is clearly a heavy displacement cruising boat. You can load her down with all your cruising gear and equipment and it will hardly affect her waterline. Not an ideal choice for coastal sailing, but she'll come into her own on an offshore passage in testing conditions.
4. Ted Brewer's Comfort Ratio of 31.0 suggests that crew comfort of a Colvic Countess 37in 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 1.9 tells us that a Colvic Countess 37 would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.
