Character
Where this design lands on the numbers a shopper trusts — read straight from her own ratios.
Her light displacement on a moderate beam gives 12 — a quick, lively motion that feels every wave.
At 2.36 she sits above the 2.0 line — beamy for her weight, and happiest coastal.
98 — light for her waterline, so she is easily driven and quick to accelerate.
23.0 — a lot of sail for her weight; powered-up and eager, a real performer.
52% of her weight is ballast — very stiff, carrying full sail in a blow.
Light and lively — happiest day-sailing and coastal-hopping in settled weather.
- Lighter than ~79% of boats her size on file
- Draws less than ~82% of boats her size on file
Compared with 1987 boats of the same type within a quarter of her length.
