We are able to fill the aft tank by plugging the round fairlead/drain on the starboard side, closing the drain valve below the nav desk, and opening the deck fill for the aft tank.
We can transfer water from the aft tank to the forward tank by opening a valve under the head compartment sink that recirculates hot water back to the forward tank. (The real purpose of the valve is to prevent wasting water waiting for the hot water to get from the hot water tank to the head sink tap.)
We can fill collapsable 5 gal WalMart jugs from the galley sink either for storage or to pour them into the forward tank.
I installed a Forespar 3-way valve in the deck drain line that passes through the galley cabinet. One port receives water from the deck, one port is connected to the original thru hull drain, and the third port has a male hose connection. I can plug the port fairlead/drain, attach a short length of hose to the 3-way valve, switch the valve to the hose, and fill 5 gal jugs on the galley sole.
I made a 16" diameter funnel with a male hose connection at its small end from Weblon vinyl that we can use to collect water spilling from the mast or boom. Grommets around the big end edge let us tie it where it does the most good. It is handy when we are sailing in the rain, but it has actually gotten most of its use filling jugs from the outside shower at No Name Harbor on Key Biscayne where there are no water taps. I just tied it around the shower head, ran a short hose into the jug, and kept an eye out for the ranger.
I will be adding drains to the low spots of our sun awning shortly. I've marked the spots where water collects.
This year we bought no water in the Bahamas. It was a first mostly because it rained more than the previous four years, but partly because we were prepared.
