Character
Where this design lands on the numbers a shopper trusts — read straight from her own ratios.
Her heavy displacement on a beamy beam gives 22 — a moderate, middle-of-the-road motion.
2.04 — right around the 2.0 line, the edge between coastal and offshore.
306 — heavy for her waterline, built to carry stores and ride steadily.
13.3 — modest power for her weight; easygoing rather than lively, and happier with a breeze.
40% of her weight is ballast — moderately stiff, a middle-of-the-road stability.
A balanced, easily-driven cruiser — comfortable and forgiving for coastal work.
- Heavier than ~84% of boats her size on file
- Beamier than ~83% of boats her size on file
Compared with 562 boats of the same type within a quarter of her length.
