Hiya chaps,
Didn't know whether to put this here or in the beginners forum so please accept my apologies if this is the wrong place .
I have been very very very stupid

. I have spent the last 6 weeks upgrading an Anteo Tug that I bought. She has had new engine mounts, totally upgraded electrics and a lovely sound system fitted.
Anyhoo I have just float tested her tonight and discovered she is leaking.....

. After taking everything out so she is down to the bare hull and have discovered that the screws I used for the new engine mounts must have been a tad too long and have caused a hair split in the plank frame

..
I could really do with some advice as to how to repair this I am guessing It would be best to strip the hull down to the bare wood and fix it properly. So.
1- what's the best way to strip the hull, it is just loads of sanding.
2- once I am down to the bare wood what's the best repair method
3- I am guessing the whole thing needs covered in something

so advice there would be much appreciated.
I bought this boat mainly as a learning tool prior to building my first kit so she sure is fulfilling her role.......
Thanks again guys for any advice you can give.
