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 26 — a moderate, middle-of-the-road motion.
1.82 — just under the 2.0 offshore line; her beam is modest for her weight.
286 — heavy for her waterline, built to carry stores and ride steadily.
15.4 — moderate power for her weight; steady, all-round performance.
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.
