so i have a leak on our 8` rowing dingy ..

its a duel hull inner and outer skin ..the leak is on the center skeg on the bottom , it wore away from dragging on the ramp ..

so im getting water between the to skins ..

the boat looks like white plastic ..a walker bay style and shape ..

does anybody have any thoughts on how to repair ? or just look for a new one ?
i did a repair on a old plastic canoe and it never realy took ..

i was thinking using West Tex ..but were it is it would always get banged around not sure if it would hold the repair .

I believe Walker Bay has repair instructions on their website.

Something along the lines of glue sticks and a heat gun.

Just be careful how much heat you apply!

I'd call the manufacturer and ask them. Plastics are notoriously difficult to bond. I know I've had little to no luck gluing plastic things back together even with so called plastic epoxy. I've never found a formulation or procedure that had a decent chance of working. Sorry to sound so doom & gloom, but I've been pretty frustrated trying to fix problems like yours. If you do come up with a good solution, please post it so we all learn how.

My experience is similar to David's - I've never found a good plastic solution. The one I haven't tried though is a plastic welder. I have seen some plastic canoes with pretty bad holes/cracks that were repaired using a plastic welder, and they looked really solid.

I know people say all different kinds of things have worked for them in different situations (gorilla glue, plastixc epoxy kits, etc), I suspect the chemical makeup of the plastic itself reacts differs so much from plastic to plastic - and thats why it seems there's no single repair that works consistently.

(I have a broken fridge hinge in my RV that is vexing me right now - because the hinge mounts are plastic...)

Could you cut an access hole in the inner skin and then lay fiberglass and resin on the inside of the outer? Effectively repairng the sking from the inside. Use an access hole cover for the inner skin. Follow that by sandwiching the outer skin between sheets of fiberglass? Sand it smooth and sail away. Man, that sounds easy, probably isn't though. Have no idea if it would work.

Its probably HMPE, and nothing that you can fill the hole with will actually bond to it. Gorilla glue is just another polyurethane foam, so good luck.

I've used G/flex - it's a good product. Let us know if it works.

i have to check ..i just put the nice cloth bumper around the edge :/

plus i am already over the boat budget ..
if i could get it through the year would be nice ..

its hard to avoid dragging it up the ramp ..
i have wheels but you have to flip it ,
at low tied the ramp is too slippery .

i will ..i havent bought it yet , this weekend looks good
