Re: Genoa Chain Plate bolts Leaking in aft hanging closet

Dan Carlson

Hi Ken, 

We had some slight seapage on the port side chain plate ( in the head storage compartment).  My remedy two years ago was to peal back the liner, thoroughly clean all around the bolts on the inside of the hull, then seal all around with silicone sealant. Then re-attach the liner. We have had no further issues. 

I thought that taking the rub rail apart to address from the outside was asking for more problems.  

I do not think that there is a structural issue with the chain plates just over time to seal has failed.

Thanks for posting the photos. That confirms what I expected to see from the drawings that I had seen.

Best regards Daniel Carlson on sv BeBe, SM #387
