1966 CrewsCraft hull repair

[7lazy77]

I just acquired my first boat & came across this great forum & had some questions. Excuse my teminalogy on certain things, but I am still in the learning process. The boat has a few "hairline" cracks in the hull underwater, including a larger one that I am including in the attached picture. As you will notice in the picture, it appears that the previous owner put some silicone(?) caulking over it. There is also a few larger nicks out of the hull as well. I would like to make a few repairs to the boat.
The question that I have is, what is the easiest & inexpensive way to repair both the crack & the nick for a novice like me? Thanks for the help!

Ayuh,... Welcome Aboard,...

What little is visable in yer picture, I'd guess Marine-tex might be the answer...

I did a little research on the Marine-Tex epoxy putty & I think it should work. Any good posts out there that has a repair being done with pictures??

Hello lazy7 .. and welcome to Iboats ..

Hmm..that pic looks kinda fishy.

It kinda looks like wet core leaching out from the crack.

You say that picture was taken on the bottom ? ..

YD.

Yes, picture was taken from the bottom. Would a repair with epoxy & glass cloth be better?? Thanks

Ayuh,... Looks like it needs some sanding, 'n cleaning to see Exactly what's up, before formulating a Plan...

Any access from inside,..??

No need for the epoxy..poly and mat should do fine ( Thats what I would use..not filler ).
I would not deem that a "hair line" crack .

I was just wondering why its all brownish stain looking ( like bad/wet wood was under your crack ) .

I would explore to make sure your not covering up something that needs addressing before you repair.

Any recomendations on what kind & where to get this "poly & mat" from??
I will have to tear into it a little more to do some further investigating.....

Aye..polyester and CSM .

You will probably find polyester and mat from the same place you would have aquired your epoxy and glass cloth..

Epoxy/sealant applications?

Epoxy/sealant applications?

I have have been looking over the posts on repairs here & I am about cross-eyed. I am not looking at doing any one specific repair, but was just curious if there was a general "rule-of-thumb" on when you use each of the following for a specific repair: epoxy putty?? 3m 4200?? 3m 5200??

Re: Epoxy/sealant applications?

No reason to do an epoxy repair on a boat that does not require wood to glass bonds.. poly will work fine..

There is no "rule of thumb" for materials ( generally I use mat and 1708 ..sometimes woven roving ) fillers are only for fairing when I build up with glass and still have the cure time involved with cabosil/resin as I do with mat.

I dont fair with bondo..or other " fairing compounds " its raw glass..or gelcoat for pre-fair..then gel or spot prime..

There is no 4200 or 5200 in repairs..

Got some more pics ? ..

Can I get some links to some places to find this poly & mat to do the repair? Thanks for the help Yacht Dr. & everybody! This is my first time, so would like to make sure I get the right materials to do the job correctly.

Where R U Located? You COULD call a local body shop or marina and see where they get their fiberglass supplies locally. They will have a polyester resin and fiberglass mat supplier I'm sure.
