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 20 — a moderate, middle-of-the-road motion.
2.09 — right around the 2.0 line, the edge between coastal and offshore.
242 — moderately heavy for her waterline, a balanced cruising weight.
17.3 — moderate power for her weight; steady, all-round performance.
49% of her weight is ballast — stiff, standing up well to her sails.
A balanced, easily-driven cruiser — comfortable and forgiving for coastal work.
