Re: Moisture around chainplates
The chain plates on the Islander Bahama 30 are known to leak on a regular basis. I lift the small deck plates every spring and re-bed them with a Sikaflex sealer. I have also used 3M5200 but it's a real bear to get off if they ever leak again. And there is enough flexing with the chainplates when sailing that they will leak again. Same as the windows! If the chainplates have been leaking a long time the interior bulkheads will be stained where the water has run down the plate and into the bolt holes, getting under the varnish. The deck is plywood cored and unless the leak has been going on for years, should be good.
