Ken, in my US east coast travels (and the Bahamas), I find 240v almost
exclusively. In fact, at one of the few marinas that only had 208v (I think
it was Kilkenny in GA), upon hearing my comment that voltage was low,
quickly wheeled a step-up transformer down the dock to run the power
through. They did it so quickly and politely that I did not have the heart
to tell them I had a step-up transformer aboard.

Okay, here's what Cruisair says about their current units:

All Cruisair marine air conditioners run on AC (alternating current) power.
Most units are available in 3 different power configurations: 115V 60hz,
230V 60hz, and 230V 50hz.

And my units are antiques. Is it alright to subject them to 208 volts?
