VK Homemade Sail for a Small Trimaran
How easy (or hard) is it to make an inexpensive, homemade sail for a very small trimaran? That’s the question sailor Danilo Veleirok asks (and answers) in this post.
Danilo lives in Niterói, Rio de Janeiro, Brazil. As you will see, he encourages frugal thinking and DIY ingenuity in order to beat high costs and put a sail on his little trimaran kayak. Thus, he is sharing his concept of “recession-proof” sailing.
Danilo shares his ingenuity and creativity with us below, but in some written text and YouTube videos. Thanks for sharing this with us Danilo :-)
VK Sail for a Small Trimaran
by Danilo Veleirok
Are you not sailing because of the economic crisis?
Forget the crisis.
My homemade “VK Sail” is 43 square feet (4 m²) and requires an investment of about $50.00. And it will allow you to sail at most angles against the wind.
The VK Sail offers a flexible wing and is features other qualities too, including aesthetics. I tried giving it a modern look because, after all, what is beautiful can often be functional. But I have the assurance that the science of aerodynamics was also respected, I studied a lot the subject, mainly supported by Arvel Gentry (http://arvelgentry.com/)
How To Build It
This VK Sail isn’t sewn … it’s Seamless. You only need to apply eyelets.
Use a canvas polytarp 5.5 oz … good quality, measuring 13 ‘x 10′ (4 x 3 m). Following are a few images:

Note: There is a tube which serves as splice connecting the vertical edges of the rectangle, which has the function of the wing structure and format to the edge leakage. My goal is that other sailors will build and sail this VK wing and contribute to improving its design and use.
