My kid and I picked up this boat for a song - decent trailer, 2 working 60HP Evinrudes and a 75HP Johnson with a bad lower, for less than $500.

The deck was rotten, as I'd suspected. After we ripped it out, I wanted to check the stringers for rot. I drilled down through the top of one of them, and out came some rotted wood. But the funny thing was that the drill basically fell into air after about 1/2". After looking closer, there is a 1/2" strip of wood running along the top of each stringer, just under the glass, and nothing but air underneath.

Was this type of hollow stringer construction ever used? The deck was about 66" wide at its widest, and there are 5 stringers with about 8" between them. The tallest is the center stringer, a little less than 4" from top to hull. The two outer ones are less than 2" tall, and the inboard ones about 3". All of them appear to be hollow except for a thin strip of wood at the top, which I'm guessing was for attaching the deck.

The good news is that I drilled the transom in 8 different places and only got dry wood shavings.

Do these stringers need to be replaced? I can't think of how I'd do it.

And how in the world would I reattach a new deck? Would it just 'float' over the stringers and be glassed to the sides?

Welcome to iBoats!
NICE SCORE! Post some pics of the entire boat. We LOVE pics!!!!

Hollow core stringers are pretty common in some boats of that era. You're pic shows the stringers to be fabricated from Heavy Woven Roving Glass. They probably used Cardboard as Forms with the Wood tops to provide some Bite for the deck screws. How wide are the tops of the stringers. If she were my boat, I'd count myself BLESSED and check the transom for rot. If it's good to go then mix up some Thick Poly resin and Glue the deck to the top of the stringers and be done with it. She looks pretty well glassed to me from that pic you posted. Core sample the Transom and see what you get.

Mine are similar to yours with a strip of stainless steel as the "bite" area for the deck, instead of wood.. Mine is a 60 Lone Star about the same size and shape. Mine were just fine so I didn't really mess with em, just tied em back into the new transom I had to install. Looks like you saved a bunch of work if they are as sound as they look.

I drilled into the transom in 8 different spots, 4 about 1-1/2" above the hull and another 4 about 4" above those and all that came out was wood-colored wood shavings. I think I dodged a bullet there. I spotted some exposed wood, but for some reason it isn't rotted at all. Think I might dig a little of it out, and if its ok just fill it up and put some glass over it.

Thanks for the input, everyone.

Here are some more pics of it:

I'm going to have to rebuild the seats obviously, but the package included some aluminum-framed benches that are still in OK shape. Also got a complete throttle/shift assy, and a newer mint condition steering setup.

All in all, I'm pretty happy with what we ended up with, especially now that I know I'm not going to be into in hundreds of hours or $1000+ to get it back on the water.

Yeah, well from what your telling us, and what I can see, this oughta be a re-deck job and some upholstery work and some gelcoat or paint and you'll be On The Lake in no time.

Ok, I don't much if anything about glass boats but I can tell you one thing. That is one of the cutest little glass boat I've even laid eyes on! I imagine you've already fell in love with her and I can't wait to see the results of your rebuild.
