I design multi hulls for home construction since 1980 and selling plans over the Internet since 2001. I lost count of how many countries around the world my boats were built. I bring three types of experience into my designs. I studied physics. I have built 15 boats. So I know what works and what does not. I lived, with my wife, for 11 years on board our catamaran "PELICAN."
My portfolio includes a wide range of catamarans and now also an outrigger. Many of them are unconventional designs, boats for individuals like you?
Many of my inventions were copied, to name only a few. First, my vertical furling system for mainsails (1967 !) on my PENGUIN monohull, my simple rudder automatic (1980), and the negative stem (2003).
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. Can you repair a chair? Then you can build one of these boats.
I am known in the business for my personal support and the support from the K-designs forum* with over 800 members. Pick one and build it.
