too bad they chopped all the glass off the transom. I would have thought that going from the inside and retaining the outer skin would have made a whole lot more sense. Oh well...

My wife is not happy I've got a bid in on that thing!!!! [img]/images/graemlins/crazy.gif[/img]

I'm trying to convince mine to let me put a bid in on it. She's holding her ground. Maybe if I get some of her projects done around the house...?

Has'nt really moved any. How would you do that transom, they didnt leave the skin?

Well, I wouldn't prefer to do a transom that way. However I don't thank that it would be that big of a deal. Just feather the old glass out as much as possible and start building a new outer skin. Make sure that the inside is all tied in good. [img]/images/graemlins/wink.gif[/img]

Steve,

That's exactly what I was thinking. I figured I could temporarily install a mold of some sort to lay the glass against to be sure to get a nice flat surface on the inside to lay the ply against. Flat on the inside should translate to flat on the outside as well since I'd be laying same number of layers of glass in all areas.

Or, do you think it would be easier to laminiate the plywood coring first and then bond it to the boat w/ an epoxy/cabosil mix? One all of that has cured up, I could grind down some on the outer skin of the hull and build up the new skin. From there do the same thing w/ the inner skin.

Guess I'g getting ahead of myself. [img]/images/graemlins/smile.gif[/img]

The second way seems easier. What do you think?

Brian, Some of the guys on this site have done their transom this way, Hammer being one of them. They would probably be able to give better information than myself. I would take one single sheet of plywood and glass on 3 layers of mat use something like polybond to go on the hull and the sides where the plywood stops. This Polly bond will be used as a bedding compound for the plywood and it can also be faired. Have friends put the Polly bond on the hull while you are putting the mat on the plywood, and then put the wood in the boat before everything has cured. The part of the wood that was glassed will go toward the bow of the boat. Once the wood is in the boat you want Polly bond to of squished out around the edges. Have the boat's transom 3 or 4 ft from a wall so once you put the wood in you can take several 2/4s and wedge in between the wall and the wood. This will insure that the wood bonds well to the inside of the boat, as you can see you must work quickly or the glass and/or Polly bond will of set up before everything is in place. Repeat this same procedure for the second sheet of plywood. When everything has cured, then start building up your outer skin to the wood. I would use 2 layers of mat, then 1 layer of woven roven, then 1 layer of mat, then 1 layer of woven roven, next I would put 4 layers of mat. This should get you pretty close to the original thickness of the original skin. Wouldn't hurt to use a little extra mat on the outside so that you have some material to grind down and make flat. Any thing that is glassed needs to have been sanded down smooth with a grinder first. The outer skin will need to be done in two steps.

Brian,
I saw this boat over the weekend. This boat may have more structural damage other than the transom. The hull to deck joint on the port side rear has opened up for about six feet. the fiberglass liner is distorted on the starboard side between the front casting deck and the rod holder area. the same area on the port side is distorted and split open. I am not trying to discourage your puchase, but you may have to rebuild the stringers on this boat.

STRESS

OK fellas its my boat. Don't bash it too bad. I bought it about 3 months ago and started working on it when I got a set of orders recalling me for active duty for uncle sam. My orders are for me to depart end of feb, which is why I am selling it. The guy who came and looked at it was fairly accurate on everything except the stringers. They are hollow pieces of thick fiberglass, no wood in them. The transom was cut prior to me owning it but I would have done same way. I have been looking at peel-ply for the finishing of the transom and am currently trying to get some to play with from Rampage Yachts. If you have any questions feel free to ask. Wife said it has got to go before I leave or she'll give it away.
