It failed because i was slack i left the top cap open water could have channelled along and down from the top,it could have been when the hull took on water and i drilled the bung hole to drain it, the transom was the beginning of the build i used the wrong plywood it delaminated with just regular rain water
Lots of problems lots of my problems and i took to long to install and fully lock in and sealed the transom between the transom start to transom finish i had tarp failure a few times in heavy down poors all i can put it down to was lack of covering the job and taking too long to complete the transom, that first transom took something like 4-5 months my second transom in thermolite was done in 3 weeks
Where i really and honestly ####ed up was using piece together tarps to cover the boat i kept buying 5.5m tarps for a 6m hull i really needed a 6.5m tarp or larger so i had to bodge 2 tarps over each other and it came undone it wasnt untill 11 months ago i bought a huge 7mx5m tarp a bit much a bit late the boat copped afloggin just before i bought the big single tarp and it flooded 2 stringers but they were unglassed and the plywood dried out
I finally got a hang of the steering and put her in first gear and havent looked back, big learning curve PPP on my part i slacked off and it kicked my ass but i soilder thru the rough times and here i am one exhausted mf but im nearly there
