The Swan 59, a masthead sloop, was designed by German Frers and built in Finland by Nautor Swan.

4. Comfort Ratio: 45.3
5. Capsize Screening Formula: 1.7
1. The Sail Area/Displacement Ratio of the Swan 59 is not published, hence we are unable to comment on this aspect of the boat's predicted performance.
2. A Ballast/Displacement Ratio of 36.5 means that a sailboat like the Swan 59 (which doesn't have its ballast concentrated in a bulb at the foot of a deep keel), is likely to benefit from being reefed early to keep her sailing upright in a moderate breeze.
3. A Displacement/Length Ratio of 250, tells us the Swan 59 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 45.3 suggests that crew comfort of a Swan 59 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 1.7 tells us that a Swan 59 would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.
