Is it for you?
Where this design lands on the numbers a shopper trusts — read straight from her own ratios.
Her light displacement on a moderate beam gives 21 — a moderate, middle-of-the-road motion.
1.98 — just under the 2.0 offshore line; her beam is modest for her weight.
179 — light for her waterline, so she is easily driven and quick to accelerate.
17.8 — moderate power for her weight; steady, all-round performance.
46% of her weight is ballast — stiff, standing up well to her sails.
Light and lively — happiest day-sailing and coastal-hopping in settled weather.
