Hi Alan,

I have a 1965 Chris Craft sea skiff sedan for about 10 years. The problem you are seeing at the keelsom is common.
I myself would not put any thing on the inside of the boat.
However I would clean out between he keelson and the garboard
plank on the out side and tap in some woven cotton before you chaulk. Make sure it is dry and clean before doing so.
In the past i have used only chaulk and it does not seem to hold as well as with the cotton in the grove. The cotten will give it something to bite to and when the boat is in the water it will swell and hold better. Again a old timer showed me that one. I would use 101 or 4200 on the bottem, you can use 5200 also, I think the 5200 works better, and will still come out after a few years. The resson i say don't put anyhing on the inside is
it will probably break louse and just get it the way of water passeges to the bilge pump.If i can help you in any way you can e-mail me or give me a call 860-350-2368
mon-fri 8-5 Weekends i am on the DARK KNIGHT
Hope I was helpfull to you, Roland Corsi

Your 1964 Chris Craft was assembled using an early version of 3M 5200. If small pieces of the 5200 that are exposed fall off, I wouldn't be concerned. If you ever try to remove and replace one of these planks, you will find the bond almost perfect to the point where you will have to saw the plank edges apart with a hacksaw blade.

As stated above, no caulking compound should be applied inside the hull. It is useless there.

I would be very careful reefing out material between the garboard plank and the keelson on the outside of the hull. Whatever you put in there (even cotton) will keep the wood from expanding and sealing as it was originally intended to do. If the boat leaks at this point now when fully swelled, some of the fasteners may have failed due to the swelling and contracting during use over the years.

As you've probably discovered, the Sea Skiff lapstrake plywood hull is amazingly strong and durable although the same can't be said for the cabins. If it doesn't leak, I wouldn't fool with it. Eventually, you may have to re-fasten the hull but you can do that without disassembling it.
