1. Sail Area/Displacement Ratio: 14.5
2. Ballast/Displacement Ratio: 27.5
3. Displacement/Length Ratio: 390
4. Comfort Ratio: 49.9
5. Capsize Screening Formula: 1.6
1. A Sail Area/Displacement Ratio of just 14.5 suggests that the Vagabond 47 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 27.5 means that a sailboat like the Vagabond 47 (which doesn't have a stiffness-enhancing bulb keel), is likely to benefit from being reefed early to keep her sailing upright in a moderate breeze.
3. A Displacement/Length Ratio of 390, tells us the Vagabond 47 is 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 49.9 suggests that crew comfort of a Vagabond 47 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 1.6 indicates that a Vagabond 47 would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.
