Read more about these Key Performance Indicators...
1. A Sail Area/Displacement Ratio of 16.2 suggests that the Hunter 31 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 41.2 means that the Hunter 31 will stand up well to her canvas in a blow, helping her to power through the waves.
3. A Displacement/Length Ratio of 239, tells us the Hunter 31 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 22.4 suggests that crew comfort of a Hunter 31 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 2.1 tells us that a Hunter 31 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.
