i have the three AC’s I want to use a splitter at the boat with one 30AMP cord to the shore power !!
Will this work or do I have to use two cords ???
I used this setup on my 340 DA , but I only had 1AC ,
Any thoughts would be great
 
I don't know if Bop is being factitious or giving you a technical answer, but I would caution you against doing what you asked. The boat is designed to take in 60 amps and it really needs all of that when the 3 ACs are running plus hot water heater. For reference, figure each AC is taking 10Amps (with 15 amps being sucked up when the compressor starts-up!) and the water heater is about another 10-12 amps. One 30 amp cord plugged into a 30Amp pedestal connection is really not going to work IMO. Throw a hair dryer or electric grill into the mix and POOOF - breakers will pop. This is one of the few complaints I would have about this boat - I don't think the 2 30 AMPS set-up works when the boat is fully optioned with 3 acs.

Many of our boats have a Y connector that will allow you to plug into a 50 AMP connector on dock and then out to the 2 30amp lines. Bottomline though is that you'll need two 30amp lines, or a single 50amp line with splitters.

Thanks , I have a 50 amp to two 30,a splitter , I was hoping to get away from the two cord handling , that's why I asked ,I didn't think the one cord would handle the draw/demand of 3 AC UNITS
 
I had the same boat and in some docks was limited to one 30 amp plug. I found I could run 2 A/C's only and then with the water heater turned off. To run the bridge air both A/C's bellow needed to be off.
If you have two 30 amp plugs available use them.
 
The answer is yes it can be done but it is not compliant to the NEC nor AYBC as the nominal operational boat loads are greater than the allowable supply capability. This is why the marina's supply is fused with a circuit breaker. You would be relying on your capability (by switching on and off the boat's systems or what is called load sheading) to make sure the boat's loads are within the limitations of the supply and that is not code compliant.
 
I’ve got two A/C’s and wouldn’t run both at the same time with a single 30 Y adapter.
They only run at the same time if I have two 30 amp cords, a 50 Y adapter on the dock side, or when running the generator.
