Columbia - rub rail/hull deck joint??
I am currently in the process of prepping the hull for haul-out and a topsides awl-grip coat (wish me luck!) and am starting to examine my rub rail. The rail is located about 6 inches below the deck and I do believe that it is also the hull/deck joint. However, I don''t really know what this joint looks like. I have pulled the rubber from the extruded aluminum channel on the outside and have found lots of corroded rivets. On the inside of the boat, there is another aluminum channel running the entire length inside. However, there are no visible rivets on this side of the aluminum. Just a nice, smooth piece. So....does anyone know what this looks like? Should I be overly concerned with a reasonable (this is a 1969 boat) amount of corrosion? Or should I be driling and replacing rivets? Course, I would be drilling something that I don''t even know how its put together! I also have a hard time believing that the entire deck is held with just these few rivets.

I have a ''74 /columbia 23 that has an overlapping deck hull joint that seems to be "glued together (albeit not very well) and then Pop-Riveted. None of the joint is actually inside the boat so I don''t know about the aluminum channel.
I sail on inland lakes so haven''t worried about it much, but it ain''t much of a joint. It does work some in bad conditions and I have gotten some water thru the joint a couple of times; i.e. 20 gusting to 30 mph with 2''+ chop.

Check out There is a drawing of the hull/deck joint with the bracket and rivots you saw.
