Kahuna is a superb coastal and long-distance cruising boat, designed for modern wood/epoxy construction. The first boat was built in Australia, and several have been launched in the US. Others are under construction — in the US (New York) and in Europe (Italy, the UK and Russia).

Kahuna is a very comfortable boat. She stiff and fast under sail, and an excellent choice for extended coastal or offshore sailing.

Interior options

I've drawn three interior layouts for Kahuna, and all have proven spacious and comfortable.

On deck

Kahuna can be built with a short or long cabin trunk. The photos show these options


Kahuna is designed to be strip planked with fiberglass or veneer overlays, or carvel planked, with sawn or bent (steamed or laminated) frames. Her hull shape makes for a relatively simple build.


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.
