Surfing Waves

Chaps,

I have a Southpoint 10'2" thats huge fun, but recently noticed that theres some pressure dents roughly where my back foot stands. Its like the top layer has come away from rest of the board in that area. Its not letting in water or anything, just moves down a tiny bit when you press your finger to it. As its not affecting the board or me am I right this is nothing to worry about?

Was at Fistral 2 weeks ago and there were only 10 other surfers! Good big waves but bit mushy. Had a great time!

It sounds like you are saying the top layer is a bubble? If that is the case it is either water in it all ready or if your lucky it is air. It is delanination. Not good at all. You need to get it fixed.

What I may be missing is what you are saying. A pressure ding goes inward towards the center. Those are very common and I don't know if there is a lot you can do about them.

If you are talking about the small indents that go inward then you cant do a thing. If your going to surf your going to get pressure dings.

Not on our boards

Thanks Guys,

Yup, its delanination. At least now I know the right name! Looks like I need to speak to an expert, luckily I know one in north cornwall!

Thanks again,

Hi again,

Done some research. Aparently the causes are leaving it in the sun (not me) pressure from popping up (yes me at 17stone) and a crap roof rack (yep).

Solution is either to 1. drill small holes and inject some resin, squish out excess flat and leave to dry (after getting any moisture out first) or 2. use a Dremel to cut bits out and reapply glass fibre etc. Personally 1. sounds good, 2. scares me and 3. I might may go to an expert who I trust to do it instead.

Problem with this delamination is if the thin layer cracks (and it will) and water get in, thats grim!

Cheers,

Main root cause is too light a glass schedule on the deck. That's when all the things you listed start causing problems.

It's not that hard to fix yourself tho. Why not give it a go?

Thanks dougirwin13. I cant imagine its that difficult to inject some resin. I love this board, so I'll try a DIY job soon!

Thanks again all of you for the advice!

Delam's aren't the easiest repair. Is it on the deck? If so, definitely get it done professionally so there aren't any bumps or bits to grind your flesh when you're paddling. On the hull, fix it yourself if you feel competant, at least until you need another repair, then get it done properly.

All depends on how experienced/competent at repairs and how far you want to go/how much work you want to do.

If you really love the board and it's otherwise in great condition... And you don't want to try yourself. Then pay someone to do it.

The simplest repair is just resin injection. From there you can do foaming PU injection. Or cut and fill or even a micro-resto or full-resto!

i never heard of southpoints delaming before, i thought due to there construction this would be very unlikely to happen

This. Southpoint boards are epoxy, but to my knowledge there should be no adverse chemical reaction between polyurethane foam and the polystyrene core.

You can buy cans of expanding polyurethane foam. They have a nossle, so if you drill a hole with a dremel, you could probably get it under there and inject directly into the delam section. It would be lighter and fill better than resin, but it wouldn't look as nice since it would almost definitely be a different colour to the polystyrene (mine is a luminous turquoise colour). You would have to fill the hole you drilled with resin (and glass if it is big) though.
