Very interesting on the 5 year time window, def helps narrow it down. Also, located this number stamped on the top off the head. Not sure if it means anything.

The bottom plywood is mahogany, however the sides and deck appear to be marine? is this normal or did someone replace it already?

There is what looks like subfloor glue holding each panel on, not saying this is subfloor glue but it looks like it. Did they use some type of glue in 1946-49 under the plywood?

From what Brian told me seems the plywood was buttjoint instead of scarphed

Agree on Alan’s post. Had the person who reskinned it used 5200 or glassed the bottom it would have been a mess

Pete,
Ok glad I found that cast, so we have it narrowed down at least. The bottom has a the reddish brown mahogany color which I believe to be mahogany, where that pic I posted of under the deck appears to be marine, or even an exterior plywood. They look totally different. I think it should also be noted that the boat was painted brown so the PO who did the work (we assume) probably didn't care what he used. just my thoughts on that.

Thats a good point which I never brought up, The seams are butt-jointed, However, the seems are also butt-jointed on the bottom. Ahhh this thing is a mess!

That makes sense,I was thinking when I posted that- that was a seam where they did not have a board long enough but your saying it's a layer of ply that's come loose and was cut off at that angle

Not having a long enough chuck of wood wouldn't have surprised me at all. CC back then could do anything with the "finishing hatchets"!!

I agree, however, the DF really isn't needed on such a small low powered hull. If you come across some nice Mahogany, I'd be tempted to use it. But, what's wrong with the existing stringers? They should be good.

That's a classic PO patch and one spot that seems to rot. Bet you knew that Gary Ha.

The 3/4 is more than is needed. I'd go 1/2 or even 3/8 ext. Remember there's a gusset on both sides of the frames.


Take a close look at the damaged stringer for a possible repair. I'd consider epoxy insetting a Dutchman.

Im not discouraged but frankly this this is a mess, lawn mulch. This stringers are possibly the only part that could be salvaged.   I took the transom frame off today and made a template for the mahogany. I absolutely 100% could not use the existing frame as a template. so It took some time. im using the template to support the back of the boat currently I have the boat hoisted up and supported by the stringers. There was no issue removing the decking last night in this area from under the boat. I agree that it would be easier up right but Its probably all that is holding it together at the moment

I plan to do the frame first so I can start to attach the rising boards and get some stability. One side at a time would be ideal but considering all frames are cracked and sinking in, Im leaning towards removing each one then reinstalling.
