1. A Sail Area/Displacement Ratio of just 15.4 suggests that the Westerly Kestrel 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 40.5 means that the Westerly Kestrel will stand up well to her canvas in a blow, helping her to power through the waves.
3. A Displacement/Length Ratio of 320, tells us the Westerly Kestrel 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 26.6 suggests that crew comfort of a Westerly Kestrel in a seaway is similar to what you would associate with the motion of a coastal cruiser with moderate stability, which is not the best of news for anyone prone to seasickness.
5. The Capsize Screening Formula of 2.0 tells us that a Westerly Kestrel would not be as good a choice of sailboat for ocean passage-making, owing to the increased risk of capsize in strong winds and heavy seas, when compared to a sailboat with a CSF of less than 2.0.
