Character
Where this design lands on the numbers a shopper trusts — read straight from her own ratios.
Her light displacement on a narrow beam gives 7 — a quick, lively motion that feels every wave.
At 2.35 she sits above the 2.0 line — beamy for her weight, and happiest coastal.
56 — light for her waterline, so she is easily driven and quick to accelerate.
35.2 — a lot of sail for her weight; powered-up and eager, a real performer.
58% 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 ~98% of boats her size on file
- Narrower than ~97% of boats her size on file
Compared with 1128 boats of the same type within a quarter of her length.
