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 19 — a quick, lively motion that feels every wave.
1.75 — just under the 2.0 offshore line; her beam is modest for her weight.
150 — light for her waterline, so she is easily driven and quick to accelerate.
18.5 — plenty of sail for her weight; lively and quick to respond.
60% 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.
- Narrower than ~96% of boats her size on file
Compared with 562 boats of the same type within a quarter of her length.
