Well everyone, IT has begun! I took out the old seats and ripped up the carpet today. I only had about 2 hours time before I ran out of light. The story is this.... I bough the boat and did some of the checks everyone suggests on here. All seemed well when I bought it. I guess I didn't check it thoroughly enough at the seller's place because of excitement (stupid emotions). Because when I got it home and started digging through things a little more I found some rot at the bottom of the transom. Not much, until I started poking at it a little harder then the wood just started pushing away and coming out all over. It is about half rotted.

Then i realized the floor was a little squishy right in front of the bilge area. I pulled the carpet back to reveal two large holes from the factory pouring in the floatation foam. They did seal them!!! The resin seal on the flooring was cracked every where because glastron didn't put any CSM in it. So the floor rotted. I picked bits of the floor away in the very back where the stringers end and could feel the end of the stringer were rotten. So my quick transom repair turned into a full restoration in a day!

This is just the beginning. It was too dark to take pictures (need to pull out my fluorecent lights), but I will take some tomorrow at the beginning of the day. I only have a couple hours during the week to work on this and about a day on the weekends. My next step is to build an engine stand, winterize and remove the engine, then work on labeling and removing the wiring. After that I will pull the cap and let the grinding begin.


One question. Is it ok to remove the floor and stringers and just use the trailer bunks as the supports to hold the shape of the hull once it is stripped? Once the hull is stripped I plan on pulling the boat off the trailer and flipping it to fix some scratches/gouges on the hull. Then build a 2x4 bracing structure for it. Any input would be great.

Another question. I was looking for deck and transom wood today. All I could find at Lowe's was ACX plywood. I could find anything labeled AC like people talk about on here. Is this ok to use?

Re: Glastron/Conroy Z-16-S restoration

sorry about your boat being rotten....

welcome to the dry dock !

any exterior grade plywood will do.
and we really need to see pics of the bunk trailer to see if it will support the weight properly....but bunk trailers are usually fine.

Re: Glastron/Conroy Z-16-S restoration

So I worked on the boat a little more today. I took some photos before I started. Here are pictures of the trailer it is sitting on, the transom rot, and the floor rot with rotted stringers underneath. I pulled all the wiring, steering cable, and part of a seat box today. I leave for a cruise soon so after tomorrow the project will be on hold for a while. I have a list of things to do before we leave to make sure the dogs and house are set.

Glastron did a pretty poor job of glassing things. Most everything just had a thin coat of resin on it then tabbed in with one layer of CMS. I could pry the mat back with a screw driver from the wood on the seat box and then pull the wood out from between the layers. Pretty pathetic. Plus they didn't glass over the inside of the transom. They only tabbed it in and painted it. However, the tabs were plenty think and are still in place. It boggles my mind how much rot would have been stopped if they would have glassed over the transom.

At the back of the deck there is a bulkhead that sticks up above the deck height. They didn't even glass the deck to it to stop water from leaking past it. This is were the deck and stringer rot started. Plus they didn't fill in the holes from pouring in the floatation foam. UGHHHH!!!!

So in short... Do you guys think this trailer will hold everything in place once the cap, deck, transom, and stringers are pulled? Should I "beef" it some how? I was thinking a few 2x4's placed under a couple extra spots on the trailer just to be safe.

Here are the pics.

You will know its done right and the satisfaction of putting a new deck and transom will be worth it, even thought its alot of work. Wear your tyvek suit and take a cold shower afterwards! (wont open pores)

Re: Glastron/Conroy Z-16-S restoration

You got that right! I've work with insulation in houses and it SUCKS. We didn't have tyvek suits and it was 90 deg+ and in an attic. NOT FUN! But being 16 and making $25 an hour was worth it. I don't think I will ever do it for a living though.

Re: Glastron/Conroy Z-16-S restoration

Here any more pictures of my latest work. None of the demo work is very hard, it is just time consuming. I am taking measurements and pictures as I go for reference.

I think I am going to get rid of the lounge seats and put in two pedestal chairs behind the consoles. The back jump seats I will keep, but extend the middle into a bench. I want to put in a ski tripod too.

I'll probably tie it into the two pieces of ply that run bow to stern on the jump seats and connect to the transom. the main vertical leg will get put into a bracket bolted through the floor above the ski locker. That way I have access to the pin so I can pull it and remove it when I want to fish. I'll get pictures of it as I go.

I plan to drill the holes in the deck over size, lug with epoxy, let it cure, then drill the the required size for the tripod bolts. I will do this for anything else that will require through bolts for attachment.

Re: Glastron/Conroy Z-16-S restoration

Just an update and a couple of questions. I'm to the point of pulling the cap and I'm not sure how I should go about breaking loose the transom section. If you look in the pictures the one from the back with the red line shows where the cap/hull seem is. Between the transom wood and the cap is about 1/8" of thickened resin holding them together. I was able to use my oscillating cutting tool to cut through the thickened resin here, but I can't do it on the inside. There isn't enough space.

The picture of the splash well with the red line shows where I am thinking about cutting in order to remove the transom. The areas above the red line is stuck to the transom wood with thickened resin so it must be cut free in some way. Then I think I can slowly work the remaining piece of cap off the transom as I will have more room. Then I can prep both sections and glass them back together and retain the original shape.








I gave the original pictures so you guys can pull them and draw lines on where you would cut to get the cap off.

Just a bump to try and get some attention from the pros. Anyone?

Re: Glastron/Conroy Z-16-S restoration

This is a very typical problem. I always use a long sawzall blade to cut it loose. Now you have to be careful and not cut thru the splashwell. (unless you want to do some cosmetic repairs too) You just hold the saw at a slight angle and cut right thru. It will leave some wood on both halves but it's not bad to remove once they are seperated. To get the saw started I use a 1/2" drill bit and drill a few holes to form a slot to start the blade.

Re: Glastron/Conroy Z-16-S restoration

Sorry, its been a really long time since I updated this. So far the cap is off, transom is rebuilt (minus drilling mount holes), the floor is out, and the stringers out. I have pictures I will post later, but I'm in a rush to get to work right now. I do have a question for the experts though. I pulled the stringers and they were made from standard pine 1x4. Has anyone seen this before? Should I stick with the pine 1x4 and to rebuild them or would it be better to go with 3/4" exterior ply? I know the ply will be stronger, but the stringers are all one piece and are 11' long. I think I would have a really hard time and pay a lot for a 12' long piece of 3/4" ply. Let me know what you all think.

I will put up some more pics tomorrow.

Re: Glastron/Conroy Z-16-S restoration

Everything I have read says pine warps, bends, and moves worse than anything. Someone posted a thread on my posts about making stringers out of two 3/8 marine plywood offelsetting the seams if they are longer than 8ft. I have seen several guys yous white oak for board lumber.

Re: Glastron/Conroy Z-16-S restoration

Here are the pics I took forever to get them up. I bought pine, but I might take them back and get white oak. I just don't think this boat needs the expense and weight of plywood. Glastron built it without it and it lasted fine until the rot got to it. It would still be fine if they would have sealed it better.

Re: Glastron/Conroy Z-16-S restoration

Here are some closer up pics of the transom. It got PB'ed on, filleted, then a lay up of 1.5 oz CSM, 1800, CSM, 1800. The 1800 almost goes all the way across and the CSM does cover it all.





I'm in the process of making the stringers and just took a break for dinner. Porkchop, sweet potato fries, and veggies then back to work.

Re: Glastron/Conroy Z-16-S restoration

Well I made a little more progress. i made the stringers and the connecting boards from white oak instead of the pine. I figured I should use something that will hold up a lot longer if it does get a little wet. After all, I'm not a professional fiberglass guy. I'm getting better and being very thorough, but I'm no pro yet. I'll have pictures of it tomorrow. I still need to do a little more sanding to fit, make the bulkheads, cut the glass layup, prep the hull a little more, then PL the stringers in place. It got too dark to take good pictures tonight.

Re: Glastron/Conroy Z-16-S restoration

Afzape... good work man!!! Looks like you are getting it done... keep it up! Can't go wrong with oak. You're boat is similar to mine except for the outboard. Looks like your deck is in good shape, I wasn't so lucky.
Cheers!
