Does anyone know where these parts go on a Catalina 28? I came across them when I was working on a 1991 Catalina 28. The first part is a white fiberglass transmission hump-like cover that screws down (see photo). The other parts are two teak rails that are about 16 inches long and have a slight bevel half way down (see photo). At first I thought the two teak strips went on top of the deck to rest a dodger on but there are no pre existing holes up there for them. They both have three screws in them. Anybody recognize these?
