would you get 2 30A or 1 50A power cable?

    my slip provides 1 50A service. Boat takes 2 30A. Would you get a single 50A cable and split inside the transom, or 2 30A cables and split at the pedestal? If I go the 50A route, what if I transient at a slip that only offers 30A breakers? Which is more common/ versatile?

    I currently have 2 30A cables with a 50A splitter at the pedestal. All are kinda beat and not connecting together tightly (collars are broken, and the 50A doesn't fit tightly at the box).

    My marina is the same way. I’ve got 50A from shore with an immediate splitter into two 30A. From the looks of the others on my dock that seems to be the standard.

    Yup - Having the 50 to 30 splitter at the pedestal seems to be the standard. It allows you to plug in at older pedestals that may not have a 50 and only 2 - 30s or one that only has a 50.

    I have both. I use the single 50a to splitter at boat connection for my home dock and anytime I have a short run to power (it's only 25'). Then I have two 30a lines that are 50' long for transient nights.

    I find the short 50a cord much easier to deal with on a regular basis.

    Looking at prices alone, it may be the 2 30A cables. Dear lawd!

    I’d stick with the splitter at the pedestal.
    It’s one of a bunch of splitters and pigtails I keep on the boat in case I need them at different places.
    If you buy a 50 amp cable (which is expensive), you still need the splitter anyway.
    When you travel, the heavy 50 amp cable is one more thing you’ll wind up carrying.
    You’ll probably still want to travel with the two 30 amp cords anyway.
