Wynfall is a small but capable cruising boat -- although only 26' long, she has a waterline of almost 24', and displaces 9500 lbs.

Although this is an older design -- we built the prototype for Wynfall in the Pacific Northwest, launching her over 30 years ago (!) --  I still offer the plans because she is such a fine boat. 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.

Various boats have been built to the Wynfall design. One (Katla, built in Portugal), has made two Atlantic crossings.

Buying plans

All plans are sold as PDFs. These are high-resolution files, and the same as I would use to print the drawings if I were to send paper copies. Why PDFs? Because this eliminates the cost and hassle of shipping, and allows you to print extra copies as needed during the build (and you will need to after a few epoxy, 5200, and coffee spills). They can be printed at most good copy shops.
