Character
Where this design lands on the numbers a shopper trusts — read straight from her own ratios.
Her heavy displacement on a moderate beam gives 31 — a sea-kindly motion in a seaway.
1.77 — just under the 2.0 offshore line; her beam is modest for her weight.
355 — very heavy for her waterline, a serious load-carrying cruiser.
14.9 — modest power for her weight; easygoing rather than lively, and happier with a breeze.
41% 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.
