Re: Glassing a old wood hull.

My only experience with glass over wood, was the boat's keel spline rotted. It was a smaller power boat, and no way to keep ALL the water out. Unless you have a dripless packing you will get water in the bilge, and it will wick between the wood, and glass and eventually require some expensive repair.

Oh Joy was done up with C-Flex. No issues with her hull, rock solid, no delamination, quiet, fast, light. The issue is with keeping fresh water out once the boat is glassed.

Re: Glassing a old wood hull.

Some years ago a tired old 50 ft power boat got a new skin of battleship linoleum with roofing nails and roofing gum. As you can guess, the chattering class dockside had much to say but the old captain fooled us all and got as many years as he needed to complete his voyage. The Gardner now powers a local yacht but you do what what you need to do.

Re: Glassing a old wood hull.

I had a 1929 Malabar Jr which previous owner cold molded and glassed. Yes there are shortcomings, but don't rule it out. For a boat that old there are also wonderful enhancements. First it will probably not weigh much more because it will not absorb water. Second, it will be more rigid. I took mine out in much stiffer breezes than many modern fiberglass boats at my marina. I put her on anchor during one of the few hurricanes we ever got. Next morning there she was looking for another day on the bay. Never did pass a crowd without someone running along shore to try to get a picture. I believe the old gal you're looking at still has a lot of life in her with the epoxy encapsulation. Yes, though it is less desired than a complete refastening. If you can afford that on a large wooden boat by all means go for it. Just my opinion.

C-flex is a viable alternative.

Yes. Aluminum. Nothing beats aluminum, except maybe copper if you can afford that. Take a look at old aluminum boats--50-60 years old. With proper grounding, double pole electrical systems, they last virtually forever. If some dodo paints it, you can always brush and it off and polish it. Deck leaks? Where? You weld stuff right to the deck, no drilling, no holes.

I'm just wondering about the pro's and con's of fiber-glassing a wood boat. Off the top of my head, it would seam that you are adding a lot of weight to the boat while making the hull stronger but perhaps slower.

What kind of things should someone be concerned about with that type of hull?
It will sacrifice some interior space, but you will enjoy the quiet. Wooden boats are more work, but they are more beautiful and the sound deadening qualities are not to be overlooked.

It beats living inside a boat that sounds like a .308 rifle going off next to your ear every 45 seconds. Or living inside a drum where every dropped piece of hardware wakes you up.

On the other hand, I personally would not consider buying a wooden boat. I don't have time for all the maintenance. There is a reason it is priced low. Be aware of the work involved. If it is your only boat, you can manage it.

The positive light this is given suggests I'm probably missing something. Does this combination end up working fairly well? For example I could believe it's unlikely to rot out because the interior wood should stay dry but can dry out if it doesn't. This contrasts with cored hulls/decks where water has ways to leak in but few ways to exit.
The procedures listed here are simply methods of saving old boats that are otherwise terminal cases, not a method for "improving" or "waterproofing" or anything else to an otherwise good wood boat. When an old wood boat has reached the point that a so-called "rebuilding" of it would actually be the construction of a new boat with a few bits of the old incorporated, the noted methods can be a reasonably economical method of saving it.

"Reasonably" being the keyword - it is still a labour intensive and costly process so the boat should be something special to be worth the investment. Probably not worth the time and money if it's just another old seiner or something like that.

Re: Glassing a old wood hull.

Agreed.

I would own a cold molded boat that was glassed with epoxy and epoxy sealed inside as well, but buying an older boat, especially one with this treatment, is a risky venture I think.
