Hello all, Just a question. My P36-2 is a shoal draft with centerboard. The pendant runs through piping up from the keel though sealed pipes and pullies on the corners in sealed housings? Mine has some green corrosion on the pipes and joints. Are these systems prone to failure? Is there maintenance that should be done? Is there any reason to consider an upgrade before anything happens? How is the plate on the bottom of the hull bolted on (4 bolts)? I did google this and came up with different discussions, but none dealing with Pearsons and no companies advertising their product. Thanks and pardon my ignorance Greg P36-2 #101
