1. A Sail Area/Displacement Ratio of 17.0 suggests that the Corvette 31 will approach her maximum hull speed readily and satisfy the sailing performance expectations of most cruising sailors.
2. A Ballast/Displacement Ratio of 46.8 means that the Corvette 31 will stand up well to her canvas in a blow, helping her to power through the waves.
3. A Displacement/Length Ratio of 335, tells us the Corvette 31 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 27.9 suggests that crew comfort of a Corvette 31 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 (CSF) of 1.8 tells us that a Corvette 31 would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.
