See our blog for further infos and sea-trials

The building of these DIY Kayak plans are based on “stitch & glue” system, so you basically stitch the plywood panels with copper wire points and then glue them with thickened epoxy resin and finish the chines with epoxy laminated glass tape, a task perfectly suited for a newbye homebuilder; anyway, don’t worry, just take a look at our blog section and you’ll find a super-detailed step-by- step tutorial.

Building is suited for homebuilders with a very basic level of experience in woodworking; it will take probably something between 60 and 85 hours to complete the kayak, depending on your level of skill; the purchase of plywood , epoxy resin, glass tape and other stuffs will cost around 450 € , depending mostly on prices of 4 mm oukumè plywood and epoxy resin on your local market.

These plans can be seen as the first step for a newbye boatbuilder , kind of practice if you want to built a “serious” boat, or a good way to employ some hours and a reasonable amount of money to built a fascinating object that will lead you to explore new environments, take you away from crowded beaches, and taste a little bit of adventure.

Plans are available in two versions: just drawings (parts have to be manually lofted on plywood sheets), drawings plus dxf templates file (to be printed 1:1 scale or CNC routed to gain an easier and more precise lofting). All seakayaks can be shrinked or enlarged in the range +/- 7 % simply rescaling the templates to better fit huge or skinny paddlers.
