Character
Where this design lands on the numbers a shopper trusts — read straight from her own ratios.
Her moderate displacement on a beamy beam gives 17 — a quick, lively motion that feels every wave.
2.13 — right around the 2.0 line, the edge between coastal and offshore.
235 — moderately heavy for her waterline, a balanced cruising weight.
15.8 — moderate power for her weight; steady, all-round performance.
35% of her weight is ballast — moderately stiff, a middle-of-the-road stability.
A balanced, easily-driven cruiser — comfortable and forgiving for coastal work.
