Rick,
Do you have folks that clean the boat on a regular basis? If so, is there a way to get them to go up into the CT and clean that place? It could use a healthy does of Simple Green and a shop vac to suck up all of the debris under the deck plates - at least the visible stuff under the metal grates and around the lower hatch. Walls, shevles, tables, equiopment, etc. It all has caked on dust and grime. It feels dirtier than the engine rooms.
