Character
Where this design lands on the numbers a shopper trusts — read straight from her own ratios.
Her heavy displacement on a narrow beam gives 45 — a heavy, notably soft motion offshore.
At 1.61 she sits well under the 2.0 line — a solidly ocean-capable hull for her size.
381 — very heavy for her waterline, a serious load-carrying cruiser.
14.6 — modest power for her weight; easygoing rather than lively, and happier with a breeze.
34% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.
Built heavy and sea-kindly — a boat made to cross oceans and forgive a rough night.
- Heavier than ~82% of boats her size on file
- Draws more than ~92% of boats her size on file
Compared with 366 boats of the same type within a quarter of her length.
