Cosmo Knot,
I have also a "tank monitor" fuse connected to...nothing. There isn't any tank monitoring system installed on my 2465. I fill up the water tank everytime I leave the dock and have a look at the waste tank when I check the engine oil level before starting the engine.
The waste pump switch was free of any connection when I looked at it initialy. Then I found the cutted "brown/black" wire in the engine room and investigate to find its utility...Result: to power a macerator. So I installed it last May.
I prefer to store the anchor light in the engine compartment (its original storage place) because of the 'softness' of the aluminium tube. Could get easely dammaged if placed elsewhere (aft berth for instance). And , as we don't need it every day (night)...not a big deal to retrieve it once in a while by opening the engine hatch.
I don't have a cokcpit table (as you do I just take the cabin table). Maybe the weight of the cockpit table, stored below the engine hatch, makes it more difficult to open the hatch. If you don't use it , why don't you remove it?
The 'history' of my boat is quite strange. Initialy bought in Florida (by Intercoastal Marine), then sent to France as a present for the daughter of the original owner. The electrical system was in 115V... (battery charger, water heather, air conditioning, electric stove, microwave...). As we have here 220V this was useless and the AC system had to be changed by the seller to be put according 'european standards'. The boat had only 40 engine hours, almost brant new when I bought it in 2005.
The good point of this is that the electric stove had been replaced by a butane one, so Admiral can cook even when on the hook somewhere... and that all this equipment in completly new.
