  1. Re: Adding fiberglass to a polyethylene kayak.

    The Old Town kit is epoxy resin - just not the type we usually deal with here, and much more like G-flex. It's the same sort of epoxy we used to use for repairing polyethylene downhill ski bottoms....

    Re: Standing lug sail

    Well, as long as you keep the part of the sail that is out in front of the mast pretty small there is no reason the thing shouldn't work. Get much bigger out there and pretty soon you have no choice...

    That's what was originally done on the blue sail. It works fine until you go boomless - at which point you don't have enough length aft for the required sheeting angle. So what was eventually done on...
