I hope you didn’t pay money for the hull. Always do a mast step test before buying. If it leaks then pass. There are too many decent hulls out there. Unless it’s free and you enjoy projects.Pickup a 2xxxx series hull. 20lbs overweighted. Mast step drinks a cup of scotch in matter of seconds. No inspection port installed.
Ordered an 8" port online, will power up the jigsaw once in. What do I expect from opening up the hull after 45 years?
paid couple hundred bucks, only able to do a knocking test all around, dry deck and hull is that all I know.I hope you didn’t pay money for the hull. Always do a mast step test before buying. If it leaks then pass. There are too many decent hulls out there. Unless it’s free and you enjoy projects.
There is a moist meter you can get for hull, they do work...Costed me few hundred bucks maybe 15 years ago to make me sleep better. But after playing with it for some time, I say a few bucks hammer + some white hair can do the job. Kinda like grandma way to picking watermelon, slight tap everywhere and wet core will sound different. You will need to know where studs, bulkhead and all.How could you tell the hull was dry? I just bought an '82 Alcort and god knows what's in there. Without an inspection port I certainly don't.
Yes, it did grind thru. If you look close, there is a small hole at the conner of mast step, where water came out. I duct taped vaccum there to suck acetone out pouring from top, and glass taping inside the tube from above, very dark coal mine to work with.It has probably worn through the bottom of the mast step as well, I usually cut a fibreglass disk (sanded smooth) out of the bit of deck removed for the hatch hole, pour in about 25 ml of epoxy resin and drop in in.
The epoxy levels out the bottom of the mast step plus fills any cracks and the fibreglass disk acts as a new floor. Just make sure the hull is level by using a spirit level across the top of the mast step and that the fibreglass disk is a loose fit i.e. it does not get stuck halfway down.
I usually add about 3 layers of fibreglass tape wrapped around the base of the mast step inside the hull as well, preferably glued with epoxy resin.
