I have ran across a late 60's 13 sport. The inside is in great shape and the wood is in storage and hasn't seen light in years. BUT....The hull looks as if it was frozen then dropped. The gel coats is cracked all over the place. I think the gel coat has shrunk. I have seen this condition on the top sides before but never like this,
Has anyone seen this before? Is it repairable? Is it worth it?
Suggestions please!

No. Steal the boat. The foam idea is great for sales, but crap for reality. Just rebuilt a 1978 V-20. Nice finish, but not because of anything the factory or the idiot engineer that designed it did. Tough rebuild. Don't do it. Get a Contender or something.

HUH? What are you saying? Have you seen what a Contender looks like after 3 years? Maybe I need to re-phrase my question.
Has anyone seen a hull with gel-coat shrinkage and is it repairable? (concerning whalers or gel coat shrinkage repair only)

I too am very curious about this topic. I recently looked at an early Nauset with extensive gelcoat cracks in the interior. None seemed to be deep or wide enough to allow water intrusion, but some could get that way fast without a little work. Price seems fair ($4000 with a '94 Mariner 90 and newer trailer), but the condition of the hull frightens me some. Any input greatly appreciated. Thanks.

These types of cracks or better described as 'valleys' are caused by improper mix of resin and catalyst. In the composite industry this is called 'resin starvation or resin rich' as the case may be. They are NOT stress cracks or cracks in the gel made by impact. Usually I see these in the area of the transom/cockpit sole transition area and also at the bow just aft of the anchor locker bulkhead, once again at an interface or transition area.
I have a friend with a late 80's Newport that had the same problem. He wire brushed the cracks, filled with gel coat and sanded, since all were on the floor 600 grit wet is a good finish. He did this 3 years ago and no more cracks have developed.
This along with the wavy sides, bulges and depressions in certain boats are an inherent problem with the Boston Whaler method of building boats, very process intense. BUT still the BEST boats on the market. Yes, compare a 15-20 year old anybrand against a Whaler!
Sorry for the long winded reply, Monday AM and I am on a caffine high.
Is it worth fixing??? thats your call, I don't need another project. Enjoy!

Yes, I think it is repairable. Basically the glass underneath is in good shape I would figure, just that the gelcoat on the outside has shrunk due to age and abuse. If you like to sand or can get a good power sander, have at it and then come back and either re-gel or paint it (Imron or Awlgrip).

Masbama and I saw one just like this at the Sand Island Rendevous and they guy uses his everyday with the cracks in it. Has been using it for years he told us, and had just repowered it with a new 90 Johnson.

I just wouldn't pay him to much for it since your are looking at a lot of work.

For what it is worth: 11 years ago I restored a 36' fiberglass sailboat with lots of cracks and crazing of the fiberglass nonskid on the entire deck of the boad. The bottom was another problem. Gelcoat or osmosis blisters. It looked as if someone had taken an automatic shotgun and went around shooting the bottom of the hull.

Deck fix: Primed with interlux primer followed by two coats of "Brightsides" polyurethane paint. Still looks good after 11 years.

Bottom fix: removed "ALL" of the gelcoat from the waterline down and then after about 3 months of drying time in a barn put on 10 coats of "VCTAR" back on the bottom. There is no gelcoat on the bottom of the boat. Just VCTAR and bottom paint.

I will be doing the same to a 13' BW I just picked up. Hull number 877.

I wonder if you could apply the primer (to fill all the small cracks) then spray on gelcoat, rather than paint. Can gelcoat be applied over primer?

The primer I used was a for the interlux product I used. It may or may not work with the gelcoat.

I spoke to a fiberglass guy and he said to bring it back to factory would cost me about 1200 $$. I am thinking about buying it and just use it as a beater for a few months. Then in january may take it to him.
