1. Sail Area/Displacement Ratio: 13.7

1. A Sail Area/Displacement Ratio of just 13.7 suggests that the Hughes 40 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 32.9 means that the Hughes 40 will have a tendency to heel excessively in a gust, and she'll need to be reefed early to keep her sailing upright in a moderate breeze.
3. A Displacement/Length Ratio of 420, tells us the Hughes 40 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 41 suggests that crew comfort of a Hughes 40 in a seaway is similar to what you would associate with the motion of a heavy bluewater cruising boat. Pitching and rolling will be well damped - your cup of coffee on the salon table stands a reasonable chance of staying there in most conditions.
5. The Capsize Screening Formula (CSF) of 1.8 tells us that a Hughes 40 would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.
