Had that problem this year in new marina even with all boat breakers off as soon as i plugged into receps on boat and flipped the mains at the shore power conns it would trip. so then i moved my cord to a different shore pedestal and it was fine. Called in the electrician who had installed the breakers and he fixed the problem by replacing the gfcis. This marina has had this issue with several boats.
