'89 Glastron Carlson 23CSS Project and Repair
« on: January 01, 2018, 08:39:32 PM »
Hi everyone! So back in June of 2017 a boat that I have had my eye on for many years finally went up for sale. It has been in a driving shed at this cottage resort for the past 25 years, only used for a few weeks out of each year, but for the past 10 years it hadn't budged. It's a 1989 Glastron Carlson 23CSS with the 350 Mag Alpha One package. It runs, it drives, it's in really good shape and it also slowly sinks..
The boat had hit a rock and damaged the hull right below the gas tank, it was patched when it happened 10 years ago, but the patch didn't hold. My plan is to pull the floor and tank to fix it properly, along with some other updates and repairs.
Here are some pictures!

Although a sinking boat isn't funny, I had to laugh at your description. All in all it looks to be in great shape. Nice score.

      Sounds like you have a good plan to pull the floor and tank and make the repairs correctly.  Given time, the water that got in could have damage other wood components as well.  It will be a project, but worth the effort when complete.

Well I was unsure it was even going to fit in my dads shop, but we got it in! Itís touching the back wall and had to take the hitch off the trailer to get the door closed! But that means we donít have to work outside!

I would consider building a cradle for the shop work, or support the hull in a manner that allows access to bottom.  A cradle would allow it to be positioned easily in the shop.  Pulling the drive can also give you a little more room.

So the problem I have is that I donít have any means of pulling the motor or getting the boat back onto the trailer if it comes off at that location, only have a small engine hoist. However I am able to take it to my work and use cranes. My plan is to pull out all the interior and floor, then take the engine out, fix the hole / stringers etc, then build a framework so that I can flip the boat upside down and rest it back onto the trailer so I can fix the bottom. Because who wants to sand upside down! Haha
Iím not really sure of the work it would be to split the top and bottom, or if it would even be beneficial. Definitely open to suggestions!!

Flipping that monster unseparated may present a challenge to say the least.  Taking it on and off a roller trailer on the other hand should be a snap in comparison.  There are members here who have worked the larger Glastrons, they will have better advice on flipping. I would agree that sanding overhead isn't fun, but might be easier than flipping.  Honestly, most of your work is from the inside sealing and structurally.  On the bottom, sand, fill, and blend gelcoat. Probably a bit oversimplified as I've not personally seen it other than pictures.

Donít flip the boat just to sand the bottom. Not worth it. Hire a neighbor teenager to sand the bottom if you have to. Taking the boat off a roller trailer on the other hand shouldnít be bad.

Well, yeah, but he has a lot more than just sanding to do...all that gel around the 'hole' needs to come off back to good solid gel.  Can you repair that with it upside down?  I'd think the gel would just run down until it cured.

I just finished rebuilding one of these from the ground up. I split my hull however mine needed A LOT of work.  As mentioned I wouldn't flip it just to fix one hole. Most of the work can be done from he inside. Then like Mike said the outside would just get a layer or 2 of glass grind it somewhat smooth. Then some filler make this really smooth. Then epoxy prime, and gel coat or Paint what ever you prefer. Since it is on the bottom you should even roll the gel coat on with a roller or paint it with a brush if you wanted.

Here is a pic of what the floor structure looks like.

Here is a link to my complete rebuild. There are a lot of pics throughout the whole process.
I think this has become an addiction.

All depends on how you do it. If you are spraying it won't be a problem unless you put to much on. Rolling or brushing again unless you put on really heavy coats. Just put on light coats and more of them. Think of a car there are a lot of spots that are upside down when painted, like bottom of doors, bumper, rocker panels, etc.

There is also a fair bit more than just the one damaged spot. There are nicks and scrapes and a couple chunks out of the strakes. The bottom really isn't all that pretty. For curing, sanding, painting etc I can't see a good job being done without it being upside down.
I don't really want to split it either, and having bridge cranes at work I should be able to rig up a framework to support it while being flipped. I know it doesn't sound easy but I think it might be the best way.
The other option is to take it off the trailer and work on it on its side, leaning on the half of the hull, then work on the other side. But still doesn't sound as nice as it being upside down.

I have read through your rebuild thread Shawn, you did a great job on that 23. It definitely looks much easier to handle in 2 pieces.

Thanks for the input guys!

I will throw in my two cents...
Although I didnít have to do a major repair like yours, on our 1900 I did do all the minor repairs to the bottom and gel coated the entire thing with it hanging from the ceiling. I did not need to split the hull, and wasnít willing to try to figure out how to safely flip it. Just a note on leaning it up on its side, I did that with our GT 150, I thought i had supported it well enough but the starboard side did gets pushed in a little bit from it sitting in one spot on the rub rail.

Hanging pix


This brace with 2 comalongs held the front up, The back at a strip through the tow hooks.
Not sure if you could pull something like that off with the 23 or not. I fabricated a 90į fitting to hold the cup on my spraygun and sprayed the gelcoat on the bottom, I did not sand the entire bottom left it orange peel

Never seen it done, but having access to bridge cranes could make it feasible.  Do all the inside, then have a jig ready to support the assembly(by the new floor), then back on trailer upside down.  Assuming everything is out first, drive, engine, interior.  Tie it down well and back to the shop to do the bottom sounds like a plan.

On another note.

While some like roller trailers, others dont.  I personally cant stand them and won't own one. Here is a pic of the indents left by the roller trailer mine came with. One problem was that it wasn't set up right.  However if not supported well they can and will leave indents, if the boat is not properly cared for.

If you have access to a crane I would flip it as well. It is much easier to work on. I missed that when I read it the first time. There would be a lot of work to split the hull just to work on the bottom.

Hanging it is an idea as well.
As long as I can make a frame to support the sides, fasten to the new floor/ribs it should be fine to set it down on that, instead of transferring all of the weight along the seam of the top and bottom. It will be interesting on how it will fit back on the trailer.
It would just be a bare bones hull and frame at that point, after pulling all the interior and engine and drive, cut out a lot of the weight as well.

As for the roller trailer this is the first one I've been around, both my fathers boat and my smaller one are on bunk trailers. It looks to me that this one is set up okay, but I am worried about it having dimples, pretty hard to tell how it is now. But the boat as been on the trailer for most of its life, be interesting to see!
More imperfections in the hull the slower she goes!
