Hey guys,
a friend of mine has just bought a naish ar3.5 and we have no idea how to convert it to four lines. It has the attachment points but no velcro to change it! Are we missing something simple??

Hey Its been a while but I think that if you look on the webbing attatchment points you should see a couple of holes. Roll up the corners by folding them tip to trailing edge then tie wrap ot rope tie the ends to sto[p them unrolling. Be careful launching it for the first time because no matter how lucky you get it will be wrong. If it flies backwards your front lines are too long. If it won't steer or the back lines are loose lengthen the front lines. If you have problems our website has some tuning tips on kite setup.kitesurfpr.com. Sorry some of it is under construction still.
Aloha Royce.

Cheers bro!! this has helped!
