Summary Analysis of the Design Ratios for the Boothbay Explorer

1. A Sail Area/Displacement Ratio of 15.3 suggests that the Boothbay Explorer 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. The Ballast/Displacement Ratio of the Boothbay Explorer has not been published - unless you know differently in which case, contact us.

3. A Displacement/Length Ratio of 321, tells us the Boothbay Explorer is 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 she'll come into her own on an offshore passage in testing conditions.

4. Ted Brewer's Comfort Ratio of 44.6 suggests that crew comfort of a xxxx 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 xxxx would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.
