WYNFALL sailing in the San Juan Islands

Wynfall represents the smallest boat that I feel is safe and practical for extended ocean cruising. Although only 26' long, she's a big boat with a waterline of almost 24', and displacing 9500 lbs.

We built the prototype for Wynfall in the Pacific Northwest, launching her in 1988. I cruised and lived aboard her at various times, and she proved a success in every way: well balanced and responsive, with a good turn of speed. She is also comfortable, having a remarkable amount of living and storage space, and an easy motion.

Katla (shown below) was built to the Wynfall design in Portugal. She made her second Alantic crossing in 2011.

The success of the design is reflected by the attention she has received: she was awarded "Best Tabloid Cruiser" at the Victoria (Canada) Classic Boat Show, and has been featured in WoodenBoat, Classic Boat, Waterkampioen, and Water Craft magazines (see publications page for references).

Wynfall was originally designed as a traditionally built keel boat, with carvel planking over steamed oak frames, on a sawn or laminated backbone. At the request of a builder in Belgium I've prepared drawings for a strip planked centerboard version as well. In both cases scantlings are generous, resulting in a strong though not overly heavy boat. Her hull shape would also lend itself well to cold-molded construction - I'm happy to advise on any necessary adjustments. The centerboard Wynfall draws just 2'-10" (as compared to 3'10" for the keel version), and includes a tabernacle mast.
She is offered with a choice of gaff or Bermudan rig, and long or short cabin trunk.

The prototype was fitted as a gaff cutter,
and the rig has proven to be handy, close winded, and fast.
It also looks great.

Several accommodation options are available,
with a choice of two to four berths.
