Character

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

LivelySea-kindly

Her moderate displacement on a moderate beam gives 36 — a sea-kindly motion in a seaway.

Comfort ratio 36
CoastalBluewater

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

Capsize screening 1.77
LightHeavy

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

Displacement / length 236
EasygoingPowered-up

19.3 — plenty of sail for her weight; lively and quick to respond.

Sail area / displacement 19.3
TenderStiff

33% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 33%

Powered-up and quick to accelerate — this one likes to sail.

  • Heavier than ~90% of boats her size on file
  • Beamier than ~85% of boats her size on file

Compared with 2129 boats of the same type within a quarter of her length.
