Reading between and across the lines in the various posts, it seems that some people are discussing a 50 amp cord from the boat, with a Y cord on the shore end to plug into two 30 amp/120V outlets, while others are thinking of a 50 amp/240V outlet on the dock, with a Y cord permitting two 30 amp 120V cables to 30 amp inlets on the boat.

The first arrangement will have 30 amp breakers on the dock, and a two-pole 50 amp breaker on the boat, while the second will have the 50 amp two-pole breaker on the dock, and 30 amp breakers on the boat.
