Character

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

Shoal draftDraws 0.61 m, board up where she has one — creeks, sandbars and thin anchorages most keels have to stay out of.
LightHeavy

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

Displacement / length 169
EasygoingPowered-up

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

Sail area / displacement 13.0
  • Heavier than ~76% of boats her size on file
  • Draws less than ~98% of boats her size on file
  • Narrower than ~84% of boats her size on file

Compared with 89 boats of the same type within a quarter of her length.
