Character

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

LivelySea-kindly

Her heavy displacement on a moderate beam gives 27 — a moderate, middle-of-the-road motion.

Comfort ratio 27
CoastalBluewater

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

Capsize screening 1.76
LightHeavy

289 — heavy for her waterline, built to carry stores and ride steadily.

Displacement / length 289
TenderStiff

25% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 25%

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

  • Draws more than ~83% of boats her size on file
  • Narrower than ~76% of boats her size on file

Compared with 1387 boats of the same type within a quarter of her length.
