Two 30's. Set one leg as the "priority" system, which will run whatever you
deem most important, usually refrigeration, battery chargers, etc. and the
other for other things. It's easier (read CHEAPER) to get a 50 amp to two-30
amp splitter than a reverse Y connector to connect two 30's to a 50. I've
had both setups and as long as you don't mind dealing with two cords, the
double 30 is cheaper and more efficient. My last boat used a single 50
because it had a glendinning cable master to wind it up into the boat. As
always, there is a price to pay for the convenience. I had to get a 50 amp
extension cord... about $500 vs. MUCH cheaper for a couple of 30 amp cords.
Also, that reverse Y connector is close to $400, last I looked.
I would also specify switching so that you could energize both sides from
either cord, in case you only had one hooked up but wanted outlets, etc. to
all work. You'd have to manage your own use in that scenario, since you
couldn't run all the high amperage stuff, but at least you could choose
without having to set up a 30 amp splitter or move the cords from one inlet
to the other.
