Rub Rail Issues

The top and bottom section of the hull have have started coming apart under the rub rail where they are normally connected. Any suggestions on how to repair?
I’m thinking about removing the rub rail and the replacing what appears to be a wooden spacer that sits between the two layers. Probably replace it with something other then wood that wont rot and then sealing the edge so no water can get through. I appreciate any suggestions. Thanks.

OUCH!!! What brand and year of hull? Did you put the screws in the pics in, or are they from the manufacturer? I’ve rebuilt several boats over the years, and I have never seen a deck that didn’t have a flange that turned down over the top of the hull. Then the rub rail was screwed on through the sides, securing them together, rather than the top. It looks like someone, who didn’t know better, cut the deck away from the hull to gain access for some reason? Without the flange turned down around the perimeter, there is absolutely no strength to the outer edge of the fiberglass! I wouldn’t think the rub rail was supposed to hold that thin layer down to the hull by design???

…Politicians aren’t the “Oldest Profession”, but the results are still the same!!!

The boat is a just a 1999 Pacemaker Yachts Custom 19’ Center console. I picked it up a few years ago off a buddy for cheap. He is the one that put the screws in it and tried sealing it with other materials as well. I am the third owner of this boat and I got it knowing I would have some work to do. Eventually I wouldn’t mind stripping the whole thing down and rebuilding but now is not the time. What seems to have happened along the edge is the piece of wood in between the two layers has expanded and pushed the deck section up. I would like to get in to it and replace those wood pieces but I am not sure how get the old pieces out and new ones in without raising the deck off, which I don’t have the equipment to do at the moment. The lower hull section comes up under the rub rail but the top deck section stops at the edge. After replacing the wood with something else I still need to find some way to seal that edge and then replace the rub rail. Thanks for any ideas you may have. I will be getting it into a shed next weekend where I can really start working on this.

I would try to replace the rail with one that has a top flange perferable made of alum. ck the internet for marine rub rail, might find some!

Most boats that size are built with an outer hull and an inner hull. The hulls are built separately and then joined like a smaller cup sitting inside a larger cup. The delamination in the pics appears to me to be the edge of the inner hull, above and distinct from the edge of the outer hull that is probably hidden lower and underneath the rub rail. IF that is the case, the joint between your inner and outer hulls is dangerously failing. I would not use that boat until I had a really good handle on what’s going on there.

If the joint between the inner and outer hull fails, the hull loses all meaningful structural integrity.

I may be seeing it wrong… kinda’ hard to tell in the pics. Might just be cosmetic. But, if it is not, it is dangerous.

Thanks for the help everyone. I will be looking into it all more seriously next weekend and let you know what I find. I will also try to take some better photos.

I’m thinking the same as you. I’d take that rub rail off now and see what the story is. Doesn’t look good.

Yep, that doesn’t look good at all, or safe.

I will be taking out the liner this weekend and would like to go ahead and start ordering materials. Any suggestions on the amount of epoxy resin, fiberglass, and foam I may need for this job?? Also looking for suggestions on the different types of fiberglass (cloth, 1708 biaxel, CSM, etc)that I should use in different areas of the boat such as stringers and the deck. Thanks.
