I know pictures would help, but it will be tonight before I can take any.
I am reworking a 1988 Marlin Ski Magnum 19" ski boat. I bought it Labor Day and have gotten the teardown pretty much done. Floor was redone before I bought it and it covered up some pretty bad water damage. The center stringers had been "reinforced" with 2x4s sistered alongside the engine.
Transom was so rotted that there was literally nothing left when I went to remove it except for mulch. it was a 3 piece transom of 1/2 plywood. I'm going back in with 3/4 ply in the same 3 piece pattern and will probably add a layer of 1/4 ply all the way across to beef it up just a bit.
I've gathered up most of the parts for the rebuild and have my wood in the house where it has been drying for about 6 weeks now. I'm waiting for some warm weather to glass in the new transom before I cut out the 2 center stringers that the engine rests upon.
For the most part I think I have a good grip on what I need to do from this point forward with one exception.
On either side of the hull is a channel that had dimensional lumber that the floor was screwed to. I would call them stringers . . . but there was almost nothing left of them and what I can see is that:
1) they were not glued or bonded to the hull in any manner
2) where they turn in towards the centerline of the boat as they approach the bow, rather than a curve or slanting, they make a sharp 25 degree angle and extend straight for the last 2 1/2 feet or so.
There wasn't much wood even left so I can't tell how it was done before, but my question is. . .
Is it possible that these outside "stringers" were merely floor supports?
If so, when replacing them should the two pieces be joined in a special manner at this joint or is any joint at all even necessary?
My first inclination is to laminate multiple pieces of wood to step inward and then come back and cut the wood into a curve. This would be a major pain in the *** since the wood is about 6-7 inches thick here, but it is doable (thankfully I have multiple chain saws LOL)
But on the flip side, it seems that most of the structural strength comes from the two center stringers and that this area is a low stress spot on the boat. I don't want to create unnecessary work for myself (I have plenty left)
So does anyone have any experience that would give me guidance?
