Shore power and adaptors
I have, on board, about every adapter possible. My permanent slip has a dedicated 50A 120/240 power cord. I do not remove it when I travel. I have 3-30A 120V 50' power cords that I use when traveling away from home dock. My boat is flexible, wired with a single 30A inlet that will feed both line 1 & 2 at the boat power panel & a 50A 120/240 inlet that utilizes the dual 120v to feed line 1 & 2. I cannot run all powered items from the single 30A inlet and must be selective. Many of the marinas have both a 30A and 50A available at the slip power box. I use a 50A to dual 30A at the dock power box, run 2 - 30A cords to the boat that has dual 30A to 50A boat side adapter. I am sure many will disagree about having multiple adapters but it comes down to shore cord weight and cost. If you have ever handled a 50' 50A power cord or had to replace $$ cord ends, you will know what I mean. I do check my cord ends regularly and use lock rings. If the marina only has 30A 120V I can use one of the cords, no adapters. I have had to put 2 of the 30A (100') together to get to a power connector. In addition to adapters mentioned above, I have a 15A to 30A adapter, 30A to 15A, RV 50A to a 30A and 50A, 50A to 30A, 30A to 50A, 50A 120V to 30A. At one time or another, I have used all but the RV 50A to 50A. The more developed cruising areas reduce the need for "special" adapters. Your needs may be very different.
