After pulling out the boat and removing drain screw yesterday, a very large volume of water came out. I searched the hull and found no obvious cracks that would allow that much water in in two hours on the water. There are a few gel coat cracks but nothing too concerning.
After de-rigging I poured a bucket of water into the mast tube and it disappeared almost instantly I to the hull. Could this be where the water is getting in? It was a choppy day and there was water coming over the bow a few times but not enough I think to put that much water into the hull. Despite this likely not being the big culprit, this needs to be repaired and would appreciate any tips. I saw the other mast repair topic on the front page and will use as much of that info as I can.
Now I'm left thinking the water might be getting in around the centreboard pocket. I see no cracks or gaps in there, so is there any good way to test the integrity of the pocket?
It's also important to note that this isn't on a Laser but an Invitation 3.8 which I guess is similar, but there are no forums I've found for this boat. Hopefully you guys will welcome me regardless.
It sounds like the bottom of the mast tube has been ground away by the mast rotating. It was a common occurrence with Lasers and only fixed once the builders put a stainless plate in the bottom of the mast tube.
