1. Sail Area/Displacement Ratio: 16.7
2. Ballast/Displacement Ratio: 39.5
3. Displacement/Length Ratio: 274
4. Comfort Ratio: 33.1
5. Capsize Screening Formula: 1.8
1. A Sail Area/Displacement Ratio of 16.7 suggests that the RH 43 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 39.5 means that the RH 43 will initially stand up reasonably well to her canvas in a moderate breeze, but she'll need a reef in the main to avoid heeling excessively in a gust.
3. A Displacement/Length Ratio of 274 tells us the RH 43 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 33.1 suggests that crew comfort of a RH 43 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 1.8 tells us that a RH 43 would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.
