After looking at the other rebuilds for a long time I am ready to start mine. I have a 69 22-2 that my dad bought new at Gasparilla Marina 50 years ago. I have been through a bunch of boats since then but held on to the 22-2 all these years. It is a boat I fished in with my parents and grandparents, I know have grown children of my own. It is time. I will be posting pics and seeking input as I go, advice is much appreciated. Thank you to all who have done their projects already, I have dozens of screen shots and pages and pages of notes based on your work. Rob

Welcome Aboard Robert. Good luck on the rebuild and we'll be here whenever you have a question.
-
Thanks Rick, here are some photos over the last few weeks, getting started.
-
Then starting on the stringers. This is going to be a total redo, There was one cracked stringer on the starboard side but other than that they were in good shape for a 50 year old boat.
-
Robert, if you want to post a pic when you talk about your boat, which you should, follow the instructions here http://classicaquasport.com/smf/index.php?topic=12725.0 - don't attach them, this is better for viewing and you won't be limited by size.
Spend a few minutes to absorb the instructions. It's really easy.
-
Ahh, I will work on that right now. Thanks

Here are some pics of the transom removal. I wanted to leave as much of the old outer skin as possible and clamp new material to it with wet glass in between. I cut around the edges with the sawsall and multi tool, I cut some long PT wedges and drove them in between the wood and outer glass. Once they separated I cut the transom up into 3 pieces, much heavier than I expected, I don't believe the new coosa transom will be as heavy even though it will be taller.
-
Going to do a little more grinding, pressure wash it and take it to the sandblaster to etch the inside a little. This is where I am today. Sorry for the small pictures, I can't follow the steps on my iPad. Will have to get on my office computer to fix.
-
My plan is once I get the boat sandblasted I am going to put in the new coosa transom. After that install one layer of 1708 on the entire bottom of the boat and up the sides to the height of the new floor. Then start fitting stringers.
-
It’s so cool that your giving new life to a family legacy. Do you have plans to keep the boat square while your doing the transom and stringers?
-
Cool boat, and awesome that it was your dad's. Looking forward to watching the build. We were at Eldred's today right around the corner from the Gasparilla marina. Good luck!

I am going to leave the hull on the trailer to do the work. My plan is to block the trailer flat and level then brace the boat off both the ground and the trailer. For being as old as it is it was pretty true before I started cutting. No visible hook in the bottom but I am not going to block it until I get if back from the sandblaster. Ironically getting it sandblasted at Gasparila Marina the same place it was sold new, Chris at Gasparilla Marine Services is taking care of that. Thanks Mike, it will be fun!
-
Been busy but got the hull to Gasparilla to have the interior sandblasted, well worth the money. Inside is clean and ready to accept glass.
-
Definitely the easy way
-
Better than spending the hottest part of the year grinding glass. I know!
-
Sorry I have not been posting my progress but am catching up today. Also want to appologize for the small formats pics. I have not been able to figure out how to do it on my iPad. Going to turn pictures over to one of my kids to do on desktop
-
So I got the hull sandblasted and back in the barn. Blocked the trailer up solid and level. Then blocked the boat up true on the trailer. Going to lay 1 layer of 1708 in the bottom up to the height of the new floor.
-
Got the layer of 1708 biaxle in the floor to beef up the hull. Now going to repair the old transom to have something solid to epoxy the new coosa board to. Going full height of the gunnels then crown in the center about 1.75" higher.
-
I laminated two pieces of 3/4" coosa with a layer of 1708 biaxle with west systems epoxy. Then clamped the new laminated coosa transom into the repaired fiberglass skin of the old hull. I used almost a gallon of epoxy mixed with milled fibers to adhere the coosa to the glass and then clamped the crap out of it. This removed pretty much all the waviness in the hull. Seems rock solid.
-
Filled in the small voids on the edges of the coosa with more epoxy and milled fibers. Went back with 2 layers of 1708 with vinylester over the new coosa, lapped the first layer about 3 inches and the next about 6 inches. That pretty much completes the transom replacement.
-
Next step is stringers, bulkheads and fuel tank install. I have been glassing 1" sheets of foam on each side with 1 layer of 1708. Once the main stringers are in I will cut these out with the jigsaw to make bulkheads and deck supports out of. Also covered the 52 gallon moeller fuel tank with 1/2" foam exercise mats. I wrapped the tank and foam with plastic and got most of the wrinkles out. I glassed over the bottom and the long sides with a bunch of scraps and made a fiberglass cradle to bed the fuel tank in. Felt like it was a good use of the scrap.

Nice progress!! Be advised that you need to allow growing room of 1 - 1.5% in all direction for the poly tank.
-
Hi Rick, I didn't know that about the poly tanks, good to know. I am hoping that the the foam mat will take care of any expansion as well as give it a nice abrasion free place to rest.
-
Lots of progress, looking good. :coolth:
And the pics showed up as thumbnails on my phone but if I click on them they expand to full size.

The expansion is a chemical reaction with gas and expands but doesn't contract. I have no idea if it can be contained with glass.

Got a little more done this weekend. Stringers are shaped and the rear ones are bedded in with thickened epoxy, the front haves are just sitting in but will get them down this week.

How is the rebuild going? Any updates?
