Character

Where this design lands on the numbers a shopper trusts — read straight from her own ratios.

Shoal draftDraws 0.76 m, board up where she has one — creeks, sandbars and thin anchorages most keels have to stay out of.
LivelySea-kindly

Her moderate displacement on a moderate beam gives 28 — a moderate, middle-of-the-road motion.

Comfort ratio 28
CoastalBluewater

1.77 — just under the 2.0 offshore line; her beam is modest for her weight.

Capsize screening 1.77
LightHeavy

275 — moderately heavy for her waterline, a balanced cruising weight.

Displacement / length 275

A capable cruiser that sits just inside the offshore line — coastal work with real passages in her.

  • Heavier than ~90% of boats her size on file

Compared with 562 boats of the same type within a quarter of her length.
