Character
Where this design lands on the numbers a shopper trusts — read straight from her own ratios.
Her moderate displacement on a moderate beam gives 30 — a moderate, middle-of-the-road motion.
1.85 — just under the 2.0 offshore line; her beam is modest for her weight.
189 — moderately heavy for her waterline, a balanced cruising weight.
7.8 — modest power for her weight; easygoing rather than lively, and happier with a breeze.
36% of her weight is ballast — moderately stiff, a middle-of-the-road stability.
A capable cruiser that sits just inside the offshore line — coastal work with real passages in her.
- Heavier than ~78% of boats her size on file
- Draws less than ~95% of boats her size on file
- Beamier than ~76% of boats her size on file
Compared with 2362 boats of the same type within a quarter of her length.
