Crosby sled

I was recently given a crosby sled and have it down to the bare hull due to some hull repair,soaked foam, and transom replacement that need to be addressed. Just had a question. When trying to separate the cap, I noticed that the floor was what I assume to be fiberglass and was attached to the rest of the cap as one piece. I had to cut the cap in a few places as well as cut around the perimeter of the floor in order to remove it. After removing the floor and foam I noticed there were no stringers in the bottom just foam. Has anyone else experienced this?

Never myself but have heard of some boats, like a Carolina skiff, that have no longitudinal stringers but do have lateral and lots of foam. Read some stuff on some sites when doing some research a while back of folks designing and installing their own stringer system and attaching it to the transom. Foamed in between, ground somewhat flat and chop mat floor. If you have it all out you essentially have a blank slate to build as you please. Composite or wood is also up to you. I have the desire and enough smarts to build one but no space for a long term project like that. Let us know what you decide to do with it.

This is what I'm working with so far. You can see where the fiberglass floor was glued down on the outside edges and two places in the middle the full length of the boat. About middle ways down the hull there are 6 studs that go through the hull and the floor was also held in place by them. As far as the studs go I haven't determined whether or not that was factory for a console or if someone did that sometime afterwards. When I received the boat it had been changed from its original seating configuration to stick steering. And also if you look at the transom area closely you can see where someone attempted to raise the height of the transom for a long shaft motor. The only way I can see that the floor was foamed from the factory was that the foam was poured in the floor and then shaved down to accommodate the floor which was glued afterwards because the floor and sides of the boat were one piece.

I like the project. Lots of grinding and reassembly but it would come out nice. BC exterior plywood is so close to marine it stinks and half the price. Got mine at Lowe’s. I also pretreat all wood with resin thinned 50/50 with acetone generously. This is after fit and drilled and so on. Stringers sure wouldn’t hurt and there’s more than one density of foam, the smaller bubbles work better IMHO. There’s a video sequence about a Glastonbury rebuild on YouTube that walks you through a lot of what you will be doing. Holler if I can help.

I'm starting off with 3 gallons of epoxy from raka. I read that poly doesn't adhear well to old work so don't want to take any chances. I also read somewhere that 4 pound foam would work in the floor but will call the manufacturer before its purchased to be sure. I'll probably pour the hull then shave off the excess prior to setting the fiberglass floor in place. I have a long way to go with this project so I will be reaching out for help again. I will be taking plenty of photos to post my progress.

That was supposed to be a Glaston rebuild. Lots of videos for lots of different stages, pretty good stuff.

Had a 1964 model Crosby Sled. The foam is what strengthens the tri hull. I cut the floor out of mine, removed the soaked foam, put new wood in place, drilled holes and poured foam through the holes, then re fiber glassed the floor.

What do you mean by put new wood in? I don't know if it is just my particular model but there wasnt any wood(stringers) in mine at all and the floor is fiberglass. There is a channel that runs down the center of the floor that goes to the drain. I thought about trying to add stringers to mine but I would have to account for the depth the channel is on the center stringer and shorten the stringer height so the channel could rest on it. I was hoping I could reuse the original floor and stay away from a wood floor if I could help it. Also I have been trying to figure out the best way to rebuild the transom. I was hoping to use a solid transom the full width of the boat but with the shape of the stern I dont think its possible due to the angle changes. I may have to end up rebuilding the same as the original and piece it across the width of the boat but I doubt that would even add any strength. Any help with that would be appreciated

Mine was older and not double walled on the side of the hull. My floor was mahogany plywood covered in fiberglass.
