I have a 1988 Hunter 33.5. I'd like to install a second deck organizer, double line clutch (and maybe a second winch) on the cabin top port side to bring two additional lines back to the cockpit. I want to mirror the factory installation of the line organizer and clutch on the starboard side. Does anyone know if there are embedded aluminum plates that could be drilled and tapped to mount these or would adding these items portside require through bolts with backing plates.
