Tony I also have a 1986 C&C 41 CB. I've replaced the cable several times, and had some modest corrosion issues with the sheave box in the bilge, but never any delamination of the board itself. I have also replaced the pivot pin a few years ago. I have a very old slightly water damaged C&C drawing that describes the centerboard construction in some detail.
It's titled "C&C 41 CB Ballast, drawing # 82-6-21" It illustrates the Fixed keel shape, the CB shape with essentially the lines , tapers, bearing location, keel bolt locations, cable location, sheave location, tuck fairing radius, etc. For the Board, it simply states "Mold from FRP' "Add lead sheets to wieght (400 lbs)(exposed aces only)" I know this last sentence is a little confusing, but that's what is says????? Sorry, I can't be of more help. If you find out any other details, I'd be interested . Please let me know if/when you learn any further details.

They apparently are a F/G shell with lead shot /sheet placed inside. But what filler was used? Are they filled with foam, epoxy or some other material. My reason for asking is as follows: when the C/B was lowered this spring to receive it's annual coat of bottom paint, a significant area of delamination of a layer of glass was present on each side of the board running parallel to the leading edge and about 8-9" aft, separating toward the leading edge of the board and getting thicker as it progressed toward the fore. The delamination was a smooth joint ie. like a cold joint of a layer of cloth with smooth resin surface had separated. My concern then, is this separation the result of water infiltration or simply age and a poor bond for a layer of glass. The boat is a 1986 C&C 41. If the board is solid then the repair is simple. But if the board is hollow (unlikely I hope, since its supposed to sink) then the water entry point needs to be found and the repair gets complicated. ------------------------------------------------------------------------------ _______________________________________________ This List is provided by the C&C Photo Album http://www.cncphotoalbum.com [email protected]
