Backing Plates

I thought I would share what I discovered today as I removing some woodwork to gain acess to the bolts on the port stantion. I am adding SS backing plates to all stantions and rails and rebedding with butyl tape so there will be no leaks. It took a while to remove the plywood cover that was hiding the bolts to the mid stantion but have a look at what I found. A PO had cut off the bolt heads, move the base 1/2" and then Screwed it down. Screws in a Stantion base :eek:

My plan is to add acess holes in the plywood so I can get at these bolts in the future.

That's ugly. You're doing the right thing. Kudos.

I think Tom Soko (past Commodore) is famous for saying that the main thing to watch out for when buying a used Catalina is what the PO has done wrong (or neglected).

I find that with most boats. However I do buy project boats and expect to see a few interesting solutions to problems.... Not always safe, visually appealing or for that matter even practical but in the eyes of the owner... well some people should hire professionals.

This is a current picture of what Wavelength currently looks like on the inside. :) I have a few projects on the go with her. Hopefully will be in the water by the end of May.

Wow, that's got me scratching my head. Glad you found it and are taking the proper measures to correct.

What was intersting was the screw heads and bolt heads are identical. From the outside you would assume they were bolts.

I hope you share the final results with us. Also you should post more picures so we can see what is hiding behind those counters, settees, and bulkheads.

It looks like there has been some water penetration. Have you checked to see if there is moisture in the deck?

There was lots of water penatration. Windows leaked, all stantions leaked, all chainplates leaked..... Survey said there was moisture but not significant amounts. The good thing about these decks they are cored with plywood and it takes a lot to get them to rot, especially when in the winter they are frozen. ;) Where I checked around the chain plates the ply seem solid. In the next few weeks it will be all resealed with butyl tape, backing plates and larger outside plates on chainplates.

Ross, I had a brain cramp this AM and started to think about the icebox refrigeration. I have replaced my AB unit a little over a year ago. Do you by chance in your photo library any pictures of the counter area without the counter by the icebox?? It looks like you might have dismantled that as well. I'm most curious as to how the interior of the icebox is sealed or attached to the counter.

Fortunately I have not had the pleasure of taking that area apart. Usually the counters are held down with some screws from below and some times some adhesive.... I am going to try to add more insulation around the outside of the box and add a small computer fan to circulate the cold air around. I did move my refrigeration unit from the port locker to directly below in the aft cabin behind the sliding doors. Seems to work just fine there.

Thanks for the feedback, I was hoping you might have gotten into that area and had a picture. Like you I was thinking that adding insulation from the topside might be a good idea. I have to believe a good deal depends on how Catalina married the the counter and icebox together.

Has anyone seen, heard of, or done backing plates with HDPE plastic sheet? I've seen SS, aluminum, plywood, hardwoods. Just wondering if HDPE might be an option as well, given it's weather resistance, stiffness, strength, and proven use in other marine applications. I'm thinking something like 3/8 to 1/2 inch thickness would be needed.

Actually I think I answered my own question on the HDPE - it has certain limited uses, but backing plates is not one of them. I'm going with aluminum. This is strictly for deck hardware, btw.

Agree starboard / HDPE is not something I would use for backing.  G10 is missing from the list makes good backing material.

Gary. Per your request. I do have some pictures of the top of the icebox with the counter removed. I will dig them out in the next few days and post here. It's not what your thinking as I was very surprised myself .
