here is a photo of the dockside setup I use when there is shore power which there nearly always is because most boats of size require it. (you don't want to go near the little ones...no money).
I also have a complete rig on a trailer and a couple of inverters; 250EX being one. if you were to show up down here with that wacky setup you would be laughed off the job.
