read more about these all-revealing numbers...
1. A Sail Area/Displacement Ratio of just 15.4 suggests that the Allied Seawind 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 34.0 means that a long-keel sailboat like the Allied Seawind is likely to benefit from being reefed early to keep her sailing upright in a moderate breeze.
3. A Displacement/Length Ratio of 388, tells us the Allied Seawind is firmly in the ultra-heavy displacement category. Load her up as much as you like and her performance will be hardly affected, not that it was ever startling. Few if any sailboats are built to this displacement category these days - but they remain popular with some long-distance sailors.
4. Ted Brewer's Comfort Ratio of 36.9 suggests that crew comfort of a Allied Seawind in 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 1.6 tells us that a Allied Seawind would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.
