Right, so my tracks got loose 
Does it happen often? I used it almost daily for the last year learning to foil on a big wing.
But, what is the best way to fix it please?
So far I have removed the tracks and will let it dry for couple of weeks. What comes then please? Do I need to remove any of the cracked core?

Or ask @TooMuchEpoxy for simple fix
This worries me a bit, do I need to do anything in particular about the loose skin and core?
yeah pretty much need to cut it back until you hit solid and then build up from that.
I built a DIY downwind foil board and the whole thing was quite a task, I imagine this being quite a job to get it right as itâs pretty much the most important part of the whole setup
Id say this might not be worth it. I usually work from boards where thereâs flex in the boxes but the outer shell isnât comprimised and there isnât any water intrusion on delam. Have you tried warranty?
It was a cheap board. No warranty for me.
Iâd be ok to remove more material to try fix it. But what do I fill the void with then?
whatever you do, donât try fill large gaps with a hot mix of epoxy as it will overheat and destroy the foam. Ask me how I know.
I think your best bet is cutting away a large very neat rectangular void, filling that void with a tight fitting high density foam insert and mounting the tracks into that HD foam. Then glassing over that with a few full deck wraps and ideally putting a vacuum bag over it when glassing.
I also wouldnât bother personally as the chances of the boxes being rigid is pretty low unless you do it very carefully.
So it looks like thereâs a lot of delamination of the carbon and the foam on the bottom.
The repair would be as follows.
Tap on the bottom with a hard piece of plastic and listen to the sound to determine where it is delaminated. Remove all carbon that is delaminated from the foam.
Re make the track box. Id go ahead and use two new boxes and a new piece of foam. If one of thes existing boxes is cracked your not going to be able to remove it and get the foam out whole. This foam is hard to come by in small quantities, my scraps are precious for repairs like these. Ideally the new HD foam box should be longer, extending forward as far as possible, I like to go a full 24â. I also like to laminate some Carbon onto the back of the box to Give the whole box more rigidity.
Alternatively, for a quick and dirty but heavy fix you can just use wood. Iâve use pressure treated lumber to put together beginner wing boards out of trash boards.
use a router to set the box into the board with thickened epoxy. Also fill all exposed foam with thick epoxy so itâs a smooth and hard surface.
laminate the bottom with carbon, extra patches over the tracks. Larger sheets go on before smaller sheets. Vacuum bagging is required. Watch the pressure so you donât crush the board.
If youâre asking these questions you donât have the skill for this to be successful. Thsts not to say it wouldnât be a good learning experience if you intend to get into board building and do more in the future. I failed many times before I was successful with carbon lamination
I would say even if you really really know what youâre doing doing this for a performance prone board it would probably not be worth it. For a casual wing board sure
This looks like a Freedom board?
If so, save yourself the trouble and chunk it.
I donât know how they built these board to begin with. I did a 3âx4â patch to repair a ding and the resin setting up melted the cheap foam they use creating a hollow spot under the patch.
They warranted my first two boards early on when I blew the boxes out.
Yeah the track reinforcement is the weak link. The trick is to catch it before the tracks crack and suck up water and cause delamination. Iâve had great results fixing the flexy boards before the tracks crack
Perfect excuse to upgrade to a newer board.
