We also can use a 30 amp cords without a Reverse Y if we don't need the extra electricity. >>in case my ship comes in and I can afford a 50 amp cable.<< I also had a 65 Ft 50 Amp cable made up. This allows me to connect at any dock depending on which side the pedestal is on. I never end up 5 feet short again.

Having x,y,z would be ok for me, but having all other > details as rotations and scale wouldn't hurt. Hey, OpenSCAD internals people... How practical would it be to have a function that "rendered" an [x,y,z] triple and returned an [x,y,z] triple in the top-level coordinate system?

Continuing to beat this subject to death I am still trying to grasp the purpose of a Reverse Y adapter and paying $400 for it. If I tap two 30 amp outlets from the marina somehow the adapter must know which side of the 210-240V each input is in order to get me 210-240V?

Please check the status of the Y over the next couple of days in case there are any cancellations (such as this morning's Tri Swim class); the Y weather hotline is 484-984-2020. Monday, 1/26, 8:30pm-9:30pm: Tri Swim Class (Steve)...
