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 23 — a moderate, middle-of-the-road motion.
1.98 — 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.
38% of her weight is ballast — moderately stiff, a middle-of-the-road stability.
Light and lively — happiest day-sailing and coastal-hopping in settled weather.
- Draws more than ~81% of boats her size on file
Compared with 2563 boats of the same type within a quarter of her length.
