I just got my brand new COTAN 5'4" and after one hour in a choppy mushy waves i've noticed some strange wrinkles to the under surface of the board.I pressed them and they are not delaminated.I m afraid that is going to delaminate after a while.Besides the aesthetic look :( ..
Does anyone noticed the same to his COTAN?

Ps. I ride ONLY strapless and i weight 82 kg.

yeah that's a typical rrd surfboard :lol:
I am curious what rrd will say. (probably won't accept warranty issue).
My rrd barracuda has the same after couple of sessions and still holds after a year...
salerosa 3 years before didn't have this issue except dents all over, but was way heavier than current models.

How the cotan feels by the way?

so besides the optical problem it didn't delaminated?and what about the future selling of the board?

As for the feeling,I still working on it but definatly feels loose with the quad setup.probably I ll switch to thruster if I keep it :(

Those look like stress cracks.

I would be surprised that would be warrantied but you never know. Construction quality from some brands has been really lacking these days.

It looks to me to be cracks in the resin layer due to flex. The resin layer maybe too thick. If the cracks extend into the glass then its a structural problem and the board will fail.

these cracks are common in cheap popout boards. They do bad glass jobs and cover it with a thick sanding- and topcoat. And because it's to thick it cracks , easy like that.
