Is it for you?
Where this design lands on the numbers a shopper trusts — read straight from her own ratios.
Her moderate displacement on a narrow beam gives 28 — a moderate, middle-of-the-road motion.
1.75 — just under the 2.0 offshore line; her beam is modest for her weight.
254 — moderately heavy for her waterline, a balanced cruising weight.
13.6 — modest power for her weight; easygoing rather than lively, and happier with a breeze.
45% of her weight is ballast — stiff, standing up well to her sails.
Built heavy and sea-kindly — a boat made to cross oceans and forgive a rough night.
Compared with 2507 boats of the same type within a quarter of her length.
