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 16 — a quick, lively motion that feels every wave.
2.17 — right around the 2.0 line, the edge between coastal and offshore.
211 — moderately heavy for her waterline, a balanced cruising weight.
17.4 — moderate power for her weight; steady, all-round performance.
45% of her weight is ballast — stiff, standing up well to her sails.
A balanced, easily-driven cruiser — comfortable and forgiving for coastal work.
- Draws less than ~88% of boats her size on file
Compared with 946 boats of the same type within a quarter of her length.
