Character

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

Shoal draftDraws 0.69 m, board up where she has one — creeks, sandbars and thin anchorages most keels have to stay out of.
LivelySea-kindly

Her heavy displacement on a beamy beam gives 20 — a quick, lively motion that feels every wave.

Comfort ratio 20
CoastalBluewater

2.20 — right around the 2.0 line, the edge between coastal and offshore.

Capsize screening 2.20
LightHeavy

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

Displacement / length 300
EasygoingPowered-up

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

Sail area / displacement 10.4
TenderStiff

12% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 12%

A balanced, easily-driven cruiser — comfortable and forgiving for coastal work.

  • Draws less than ~97% of boats her size on file
  • Beamier than ~95% of boats her size on file

Compared with 225 boats of the same type within a quarter of her length.
