Character

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

Shoal draughtDraws 0.60 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 moderate beam gives 24 — a moderate, middle-of-the-road motion.

Comfort ratio 24
CoastalBluewater

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

Capsize screening 2.07
LightHeavy

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

Displacement / length 277

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

  • Beamier than ~79% of boats her size on file
