I'm thinking about moving my 1990 3607 aft cabin to a slip with only a single 50amp shore power connection. My current setup has dual 30amp connections. It's been this way since I purchased the boat "as is"
My question is will the single source 50amp work?
Thanks
Do I need dual shore power cables?

Re: Do I need dual shore power cables?
Yes, all you need is a splitter to plug into the 50 on the dock and you plug your 2, 30’s into the other end. If I recall, you are looking into the $500 range, but if a 50 is all that is available, you have no other choice. Google Marinco 50 amp splitter. One good thing about having a splitter, if you ever visit a marina that only offers 50’s, you are covered.
