1. In the absence of any Sail Area/Displacement Ratio we are unable to make any assessment of the Westerly Seahawk 35's performance under sail.
2. A Ballast/Displacement Ratio of 40.8 means that the Westerly Seahawk 35 will stand up well to her canvas in a blow, helping her to power through the waves.
3. A Displacement/Length Ratio of 318, tells us the Westerly Seahawk 35 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 passage in testing conditions.
4. Ted Brewer's Comfort Ratio of 26.3 suggests that crew comfort of a Westerly Seahawk 35 in a seaway is similar to what you would associate with the motion of a coastal cruiser with moderate stability, which is not encouraging news for anyone prone to seasickness.
5. The Capsize Screening Formula of 2.0 tells us that a Westerly Seahawk 35 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.
