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 23 — a moderate, middle-of-the-road motion.
1.88 — just under the 2.0 offshore line; her beam is modest for her weight.
252 — moderately heavy for her waterline, a balanced cruising weight.
19.2 — plenty of sail for her weight; lively and quick to respond.
46% of her weight is ballast — stiff, standing up well to her sails.
Powered-up and quick to accelerate — this one likes to sail.
