Kahuna Nui

The Boat

Kahuna Nui is designed for living aboard and long-distance cruising. Here's an excerpt from WoodenBoat's review:

"Kahuna Nui is the kind of boat that takes us back. She speaks to things of a bygone world -- to self-reliance, to remote islands without access to flown-in replacement parts. She speaks the language of patience, of contentment for living in the moment, of the journey being as much pleasure as the destination. ... she's for getting aboard and sailing over the horizon, with visions of palm trees lifting up out of the sea on your next landfall. Everything about her points to a boat that's less a tool for short-term travel and more a partner for the big journey. Take care of her, and she'll take care of you."

WoodenBoat No. 262, May/June 2018 Designs: Review by Robert W. Stephens 




She is available with a gaff or Bermudan rig, with a pilothouse or standard cockpit, and a choice of interior layouts. Some of the options are shown in the slideshows below

Despite her traditional appearance, Kahuna Nui uses modern construction: she is designed to be strip planked, with either fiberglass+ epoxy or veneer overlays, over laminated or steamed frames.  Some of the construction drawings are shown in the slideshow below. 

The 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.       

Payment options
