I have an older Unifoil Nimitz and it has been taking on water. I had drilled a hole in bottom, let it drain, and then got it professional repaired where I thought there might had been cracks in various spots. Well it’s still taking on water and I can see that there was a large repair done to the tracks from previous owner, possibly even new tracks put in. And wondering if it’s worth getting the tracks redone a second time. It’s a nice board but friend of mine is saying it’s going to keep adding weight with repair after repair and the board is already heavy compared to the newer gen Nimitz. I don’t really want to buy a new board but I have already dumped some money into repairs and I don’t exactly know where this water in getting in from. Any feedback is appreciated
I drilled a 22m hole in the tail, glued in a 20mm locknut over the hole, threaded a plastic electrical 20mm plain to screw adaptor into it with a short piece of flex electrical conduit. I then blew up a balloon, put it on over the end of the flexible conduit & it supplied a constant pressure of air into the board while I sprayed soapy water over it to find the suspect leak.
I got the idea after watching KT blow air into teir boards through the vent plug hole to check for micro leaks. I don’t have a vent plug but you may be able to use your vent hole.
It took weeks of standing the board on its’ tail on top of newspaper to finally have no water coming out. Some of my other boards that have taken on water have never gone back to their original weight.
gravity is not going to get all the water out, you gotta vacuum it out
or spin it out
