Yes! This is the problem I had a couple years ago at the same club, I got a newer Marinco adapter that takes two 125V Male and combines them into 250V Female ( https://marinco.com/en/p/RY504-2-30/Reverse-Y-Adapter-2-30A-125V-Males-to) , but this newer adapter has a smart sensor at the wye that can apparently sense that they are on the same Phase - so those two plugs were apparently on the same side of one phase, and it doesn't allow anything juice through. And thank you Ken H, for reexplaining that phase thing to me. I guess I did know once, but I forgot about that opposite phase. thing. I thought there was some reason it wouldn't work. So I know I could make up a 250V plug that would have neutral where it usually is, and ground on the outside ring, and 125 V of the same phase on both hot sides, I just don't know what would happen to my Air Conditioner if I flipped that breaker on, and I don't want to try - I *might* have 120V power throughout the boat, but I am guessing I wouldn't want to try to run anything that runs on 250V When I use the 125V to 250V adapter, ( https://marinco.com/en/p/S15-504/Straight-Adapter-15A-125V-Male-To-50A) , I believe it only energises one side of the system, as the outlets on the port side do not work - but it is enough to get the battery charger to run, and a fan. As for the 125V to 250V that mairnco sells for 'shoreside batterycharging", I guess I could get a regular 30 Amp plug and just wire one side to a 250V Female like the 'shoreside", but with an approved male 30 amp plug, not a household plug. I am just not going to magically get air conditioning out of a couple same phase 120 volt pedestals.
