Character

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

Shoal draftDraws 1.12 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 33 — a sea-kindly motion in a seaway.

Comfort ratio 33
CoastalBluewater

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

Capsize screening 1.80
LightHeavy

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

Displacement / length 245
EasygoingPowered-up

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

Sail area / displacement 14.6
TenderStiff

22% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 22%

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

  • Draws less than ~98% of boats her size on file
  • Beamier than ~79% of boats her size on file

Compared with 364 boats of the same type within a quarter of her length.
