background story first: when i first got my boat i pulled it off the trailer and found that the seats were through drilled from the keel side in and bolts were used to hold them down. when i finally got on the water i had quite a bit of water coming from the front to the rear and expected it to be the bolts. i replaced the hex head bolts with a cone style that fits flush with the keel and epoxied over them. back at the water, water is still coming in at an uncomfortable rate. back on the trailer and inspect the repair and its solid. back in the water and get under it with some goggles and find there is a crack in the bend at the strakes on both sides near where the seat bolts were. its not visible on the trailer that there is a crack here as its all pushed together. took it home and grind out the inside and outside and repair it with poly resin and 3m coarse mat. CSM i believe from home depot, and the poly resin is napa house brand. this was done on the trailer. this was last december. its been together for 9 trips so far without issue. an out of town friend came out with me today and had to open his big fat yapper and ask "does this boat take on water" i said no as it hasnt since that repair fixed the issue. well guess what has cracked right in the same spot through the repair. not as bad as before, but i feel its just time. i have a bit more glass experience now and found my prep wasnt satisfactory back then. ill attention that much better this time.
question time next: since the crack is only visible when the boat is floating, should i try to suspend the boat somehow to have the crack pull away before i try the repair, or try to get it mushed together and add a better layering of feathered edges on the glass, and quite a few more layers at that?
i may be using the wrong term as far as what i call strakes. i am talking about the runners under the boat closest to the keel that run from the front to the rear of the boat
