I just came accross a manufacturer of kayak sails that i have not seen before on youtube:
From thier web site:
"We are obsessed with kayak sailing along with designing and delivering the best quality compact kayak sail kits available anywhere in the world."
There web site can be found here - Its great to see more manufacturers of kayak sails - I still can't believe more people are not interested in this great sport!
Bye for now
