Character

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

Shoal draughtDraws 0.91 m, board up where she has one — creeks, sandbars and thin anchorages most keels have to stay out of.

Her heavy displacement on a beamy beam gives 19 — a quick, lively motion that feels every wave.

Comfort ratio 19

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

Capsize screening 2.16
LightHeavy

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

Displacement / length 308
EasygoingPowered-up

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

47% of her weight is ballast — stiff, standing up well to her sails.

Ballast 47%

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