Character

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

Shoal draughtDraws 1.01 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 beamy beam gives 25 — a moderate, middle-of-the-road motion.

Comfort ratio 25
CoastalBluewater

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

Capsize screening 1.99
LightHeavy

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

Displacement / length 267
EasygoingPowered-up

13.4 — modest power for her weight; easygoing rather than lively, and happier with a breeze.

Sail area / displacement 13.4
TenderStiff

32% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 32%

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

  • Heavier than ~75% of boats her size on file
  • Draws less than ~93% of boats her size on file

Compared with 2303 boats of the same type within a quarter of her length.
