I design multihulls for home construction since 1980. I lost count of how many countries around the world my boats are sailing to. I bring three types of experience into my designs. I studied physics. I have built 15 boats. I lived for 11 years on one of my boats. So I know what works and what does not.
My portfolio includes a wide range of multihulls. Many of them are unconventional designs, boats for individuals. Design styles range from the DUO 425 to a racing catamaran. Our "home-built" designs maintain the time-proven wood/epoxy/glass composite construction system, resulting in a strong, light, and inexpensive craft. The used materials, plywood and (biological degradable Epoxy is the most environmentally friendly construction system.
Can you repair a chair? Then you can build one of these boats.
I am known in the business for my support and the support from
the K-designs forum* with over 800 members. Pick one and build it.
