Character

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

Shoal draughtDraws 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 narrow beam gives 23 — a moderate, middle-of-the-road motion.

Comfort ratio 23
CoastalBluewater

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

Capsize screening 1.76
LightHeavy

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

Displacement / length 232
TenderStiff

30% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 30%

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

  • Draws less than ~96% of boats her size on file
  • Narrower than ~89% of boats her size on file

Compared with 1553 boats of the same type within a quarter of her length.
