Character

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

Shoal draftDraws 0.98 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

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

Capsize screening 1.96
LightHeavy

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

Displacement / length 202
EasygoingPowered-up

16.5 — moderate power for her weight; steady, all-round performance.

Sail area / displacement 16.5
TenderStiff

35% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 35%

A capable offshore cruiser with an easy motion when the sea gets up.

  • Beamier than ~87% of boats her size on file

Compared with 259 boats of the same type within a quarter of her length.
