Amp service for 650 from dockside power supply

John, when I came to your post 51 people had viewed it and nobody had replied. This suggests that nobody understood what you were asking and didn't want to come across as rude in their reply. Nor do I.

Are you asking what the power requirements are for the new Sea Ray 650 fly?
 
Excuse my lack of knowledge in this area, I'm in the process of fact finding and understanding this to external power to the yacht.

I remember seeing a video that showed a Onan generator accompanied by a 50 amp power cord. Is this the kind of cord and plug that provides power from a dockside power source?

Basically what I'm asking is, if I'm looking for a marina that provides an external power supply for the L series 650, am I looking for an external source that provides 30 amps, 50 amps, etc.
 
I am not exactly sure, but it would most likely be a 50amp service.

We use two x 50 amp 240 volt, 60 Hz connections to fully power the onboard systems. However, in most transient docks we use a single 50 amp cord and manage our onboard loads. The power panel is set up to share this single supply among all onboard equipment (but limited to 50 amps, of course).

Today, we are at a dock which only has 2x 30amp (120 volt) service, so we are drawing 240 volts through a smart Y adapter. This set up is not ideal, forcing us to really carefully manage loads and run the 29kwh genset while running high draw systems.

Could you please advise me on the required amp service that the 650 takes from a dockside power supply?

Don't they make a splitter box too where you can run one line from power box and convert to 2 boat connections to balance load? I forgot the name of it but I think marinco makes it.

Our boat has two power inputs: 50A 240V and 50A 120V.

If we're at a marina that doesn't have 50A 240V I have a Marinco adapter that I can hook up to two 30A power pedestal connections and it magically converts it to use in my 50A 240V power. Then I can switch the breakers on my power panel so I now magically have 240V and 120V. Don't ask me how it does that, it's all magic to my humble pea brain.
 
We are 50amp 240v and I have on board a Y adapter 2x30amp to 240 50amp, 2x 120v 50amp to 30amp, 120 50amp to 240 50, and I carry 150 feet of 30amp 120v power cord. I find very few marinas that have a 240v 50amp connection for us.

Wow! That's a lot of connectors. The one I wish I had for the last 3 days would take 100 amp dock service down to 2x 50 amp - all 240 volt. It's not a tricky thing - just need 2x50 amp breakers in a weatherproof box, some wire and the plugs. Parts add up to over $2000, and this is the only dock I've ever seen with 100 amp service but no 50 amp. I probably won't add this to my inventory.

We've cruised the East Coast US from Maine to Florida, plus the Bahamas and never run across 50 amp 120 volt.

You can appreciate this - I had the boat in Chub Cay two weeks ago and they put us next to this Viking 92EB (what a machine! my masthead light wasn't as high as his anchor). Chub just completed a complete renovation and it's really something to see BTW. That Viking had two 100 amp feeds but there was only one receptacle within a reasonable distance from his slip. So, they used the one 100 amp then split the second 100 amp through a splitter box then two 50 amp cords from the box to two other slips power pedestals. The two 50 amp cords used the two 120VAC hot legs from the other slips to get the needed 220VAC then that splitter box combined again with breakers to get the needed 100 amp service.
All of the 50 amp connections in my travels are 4 wire connections (two 120VAC out of phase, a common, and ground); if you measure across the two hot you get 220 VAC single phase.
 
John-o you will most likely have two 50 amp as does my boat, one is 120 the other 220. Which is hardly ever a problem for me. I have a splitter that can change two 30's into a 50. BTW Go for it the 650 is awesome !

Not that we have the water (depth) for you to visit, but we have 2 transient marinas (federal run) that have 50/125v single phase power on the south shore of long island.

No. Please see my prior answer. Why guess when the actual answer has already been provided?
