the worse thing you can do fiberglass on top of wods especially on one side. fiberglass is hard won't move when dry, wood is soft that will move when wet or damp, so cracking will accure. then rot will set in ...
5200 bottoms on wooden speed boats are far superior to epoxy and fiberglass cloth. If you want to do an epoxy fiberglass bottom on a wooden boat, all the old planking should be stripped off and replaced with marine plywood then glassed over. The marine plywood is stable and will not move under the fiberglass coating. That bottom will last.
In the name of neptune NEVER fiberglass a classic wooden boat! Wood flexes as it goes through the water. Fiberglass DOES NOT. Overtime the fiberglass delamination and moisture moves in, then the rotting process begins, from the inside out. In essence, you have "sealed the boats fate." That is until some poor sap down the line spends the time and effort to remove the fiberglass. The hull needed to be properly inspected. CC have double plank bottom and board n batten sides, they should not leak a drop. Shaft and rudder glands excepted. It may have cost a bit to have it done properly, but in the end it would have been the cheapest. I've stripper 3 wooden boats that were encased in fiberglass, it's an absolute nightmare. I've run out of names for the people who do it.
The fiberglass bottom destroys the value of the classic Wooden Boat. These people probably bought themselves three or four years of happy boating that would be about the max.
Epoxy and glass together ARE flexible. And epoxy will stick well into wood. You are right delamination can occur later but that can be handled. Boat will last now longer than without the epoxy-and-glass. In wood occurs also "delamination" like micro-cracks etc. so now the bottom is better secured from the cracks and possible hits to rocks or floating objects. Let the old guys enjoy their better boat now.
@@rikunevalainen8154 I'm not trolling for a fight. I'm really not. Wood and fiberglass do flex, BUT not when bonded together. They have different "flex rates" if you will. The only time fiberglass and wood works is using the West System where you saturate the wood with fiberglass, essentially transforming it to fiberglass, Talk to anyone who restores wooden boats (please note, I did say restore, not preserve or make is usable) They will all go into a rant as soon as you mention fiberglass and wood in the same sentence.
Great video, just starting my 3rd restoration on a u-22 I've had for 35 years. I think I'm gonna do what you did, don't some folks plywood strip the bottom first for best bonding of the glass ? Thanks
Great video

All I would say about this is get Dan Daneberg’s book “The Complete Wooden Runabout Restoration Guide” and read it first.
