This weekend I uncovered the boat to find brown water marks on the cabin walls. They are either coming in from the jib tracks or the stanchions. Should/can I unscrew and apply a silicone into the screw holes then re-tighten them or should I caulk the entire undercarriage or plate? Thanks, Jeff

The Brown water is normally rotting wood.
Jeff, I would remove some of the hardware and see if the core is wet. If it is I would dry it out and see if it is still sound. Then use something like 4200 as bedding compound. I wouldn't use silicone. r.w.landau

3M4200, 5200 NOT bedding compound
I use the 3M products sparingly in applications where you don't anticipate taking things apart for, at best, if ever, a long, long time. It stopped a rudder leak nicely, but when I wanted to do the real repair with epoxy, the 5200 had to be ground out so I could reglass. If you ever want to take the thing apart, use Sikaflex. You need to rebed deck hardware every few years anyway. KW

I thought Sitkaflex went out of business
Haven't seen it on the shelf, in years. That's what I used on the gap of the keel at the leading edge hull joint, that's standard equipment on H34s. After 13 years, good as new. It was polyurethane, like 5200. I don't know if they made anything else.
