My marina was built in 2007 and is only wired for 30A AC power.

I'm in the process of buying a boat that has 50A service. I'm going to contact the marina before the boat gets here to see if they can/will supply 50A power. To make sure they're giving me correct answers when I ask, I'd like to see what you guys think about it.

FYI, when the boat is in the slip it will not be running a lot of accessories. I may leave an A/C unit on but other than that there won't be a lot of high power draw things running. When we use the boat we don't sit at the dock. We board up and go.

My questions are--
--How much of a problem is it to change the dock power from 30A to 50A?
--Can they do it for just one slip or would the whole marina have to be rewired?
--If they will not supply 50A power, can I just buy an adapter to use with my 50A shore power cord to match the 50A fittings on the boat? Marinco makes a 30A-50A adapter that would work.

Thanks in advance for your help.
