1. A Sail Area/Displacement Ratio of just 14.9 suggests that she'll need a stiff breeze to get her going. In any other conditions, unless you've got plenty of time on your hands, motor-sailing will be the way to go.
2. A Ballast/Displacement Ratio of 41.6 means that she'll stand up well to her canvas in a blow, enabling her to power through the waves.
3. A Displacement/Length Ratio of 279, tells us she's clearly a heavy displacement cruising boat. You can load her down with all your cruising gear and equipment and it will hardly affect her waterline. Not an ideal choice for coastal sailing, but will come into her own on an offshore passage in testing conditions.
4. Ted Brewer's Comfort Ratio of 23.6 suggests that crew comfort in a seaway is similar to what you would associate with the motion of a moderate offshore cruising boat - most seasoned sailors can handle that.
5. Her Capsize Screening Formula (CSR) of 2.0 tells us that she would be a better choice of sailboat for an ocean passage than one with a CSR rating of more than 2.0 - but with the CSR being right on the cusp, it's marginal.
