I just bought this boat and it has some serious cracking all over in the gelcoat. I think it was from a previous owner leaving it in the water for a long time (no blisters just this extreme cracking and chipping). I want to use it this summer and then work on it next winter. I know boats that sit in the water for extended periods of time will take on water thru the gelcoat. Will this happen if I just throw it in the water a few times a week? Should I try to put a temporary sealer on it or can I just leave it alone for the summer? The warm weather is right around the corner!!!

I also have a 82, but mine dosn't have cracks like that below the water line. I do have a few at stress points, but not too bad.
I am not sure what to recommend, but will be watching this thread.

Good guess from just that pic but it is a 82 S&S !

If you want to read a ton on osmotic (is that right?) damage try this

I have a 1959 boat that did not blister but cracked as you describe, this was the same water permeable problem as blistering, but with a different formulation in gel coat. Who knows what resins manufacturers use in boat construction, it can vary from boat to boat and sometimes without their knowledge (if their suppliers change formulation without notifying).

Short stints in the water should do that boat no harm, the above author states that since breaks occur in the gelcoat, and polyester resin dissoloves in water (slowly) that the underlying laminate is in trouble, as it is unprotected. My '59 spent its whole life in the water though and is still very solid with the checkered and cracked gel coat. I think it is primarily a cosmetic problem, especially if the boat is trailered.

Of more importance, since this is an '82 and was in water a lot, the condition of your wooden stringers may be a concern. The CC site has a lot on rebuilds and inspections of this type of construction since that company stuck with it 10 years beyond Mastercraft's change to stringerless construction.

That is a fine looking S&S color combination you have.

I doubt gel coat cracks could leak through the layers of fiberglass behind it then into the stringers. Gel coat is cosmetic not structural. Stringers could be compromised from water in the bilge or water through the wooden floor or any other hole drilled in the bottom of the boat.. A boat of this age should be checked out by someone that know older boats and their methods of construction.

The first thing I checked was the stringers and they are solid! I just want to make sure the boat is not going to take on any 'more' water. Maybe I should buy a moisture meter and take some reading before and after I take her out.. Anyone done this? Any ideas on good brands?

Personal opinion, this is just the way it is with our older boats, mine looked this way but not as severe, just no way of dealing with the condition. age and use. Like someone mentioned, check the stringers, if they are solid and strong, you still have a solid boat, what you can achieve if you have the desire to love and older boat...

Where do you guys that are reconditioning these boats get all your replacement parts? (not engine parts but cosmetic parts)

Wow - that's one sharp boat. :worthy:

A newbie chiming in. I am also working on restoring my S&S (mines an '85). Looking at your photo, it almost looks like there is a bottom paint over the gelcoat that is cracking. The finish on there just doesn't have the smooth glassy look of gelcoat.

What types of parts are you looking for?

Just little trim parts around the boat... One example is the blower cover on the transom of my boat is broken and needs replacing. http://i57.photobucket.com/albums/g226/Jennie1220/blowervent.jpg I would like to get this piece replace before the summer starts because it looks like it could be really painful for people getting in and out of the water via the swim platform. But when I redo the boat next winter there are going to be lots of these pieces like this one that need to be replaced. I was just curious where everyone gets there replacement parts..

Thanks

I think your going to visit a fiber glass man and see if he can fix that then spray it gloss black.

Yeah that is what I figured I might have to do if I could not find it anywhere... Thanks for your help!

How many other cosmetic parts on the boat have you noticed beginning to fail? That one is in a bad spot, my wife used it to hoist herself up on the platform from the water, talk about getting your attention! Now you have me wondering what else is going to be trouble.

I did a lot of this same thing, who what and where do you look. You are starting in the right spot. I did a 94 205 and had trouble finding those cosmetic type pieces...still. It seems there are no ski-boat bone yards to pull parts from, search and hope, and if all else fails, customize...
Gel- I was fortunate to have 1 of 2 Carver Yacht gel/body repair specialist live up the road from my moms. He flies all over the world and fixes some hella smashed boats. He came over and looked at some cracking and flaking that I thought was terrible and said no problem. The problem with cracking is that in order to repair it properly you have to auger out crack through to the fiberglass with a bit that looks like a dremmil (knurled) for the cracks entirety + beyond to prevent it from extending. Fill in with boat bondo and then match gel and spray over. Basically in the order explained on the sited posted previously. In areas that were large, rather than try to match, I added a another matching color and stripe. Materials came from Spectra (factory supplier) and Carver. Lots of work at first, hate to grind on a boat, nervous about spraying/over spray but by the time I got to the next spot I was getting better and more confident. Gel coat is nice in that if you do mess up, you just sand it down and spray again. Take your time, mix the batches (gel) right and it is a rewarding project especially with the final product. I had a couple hundred bucks into it including the HVLP spayer I bought to lay it down. On a side, I had no previous body experience.
BOAT= break out another thousand. This is not a myth, especially for project type ownerships.
Make sure you like the boat and are willing to spend the time and money especially if you are picky and want a GREAT final product.
IMHO all the time and effort was well worth it. I have some pics that I have to scan in when I get home in June, they pretty much show and tell the story and maybe of some use when you start tackling this thing.
Good luck man-
