Character

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

Shoal draftDraws 1.10 m, board up where she has one — creeks, sandbars and thin anchorages most keels have to stay out of.
LightHeavy

124 — light for her waterline, so she is easily driven and quick to accelerate.

Displacement / length 124
EasygoingPowered-up

29.0 — a lot of sail for her weight; powered-up and eager, a real performer.

Sail area / displacement 29.0
  • Draws less than ~82% of boats her size on file

Compared with 267 boats of the same type within a quarter of her length.
