Shoal draftDraws 0.76 m, board up where she has one — creeks, sandbars and thin anchorages most keels have to stay out of.
LightHeavy

Displacement / length 166
EasygoingPowered-up

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

Sail area / displacement 16.9
  • Draws less than ~92% of boats her size on file
  • Narrower than ~89% of boats her size on file

Compared with 117 boats of the same type within a quarter of her length.
