Hello,
I have a very thin surfboard; an inch or so, and it has FCS single fin plugs (the round ones with two boxes needed for one fin). The plugs are small and hence it seems that due to not much area to glue/laminate it to the boards foam etc. the rear box of the both side fins have come loose. I can see that when bending the fin, the finbox moves in the board a bit. It looks like it has separated from the bottom laminate, there is no water inside the board.
What's the best way to fix this, please? I have the FCS fusion boxes, but they are much bigger than the original boxes and I am a bit afraid of drilling the board so much and trying to install them, as especially I am worrying if I can make the bottom laminate strong enough etc.?
Another option I have been thinking about is to try to drill on the sides of the current plugs and and fill the surroundings of the plugs with resin and glass fillings, would this be viable at all, and what if the foam has broken a bit due to plugs' movement?
Any insights on this would be highly appreciated! This is my goto freestyle stapless boards and I love it, a real bummer this happened
