At 12 pounds and half the size of the Charles it looks good but at $1500 it
is a bit out of my price range. The other thing that I wonder about is the
specs say the output voltage is within 5% of the input voltage which means
there is no protection against low voltage. Even a regular switching power
supply supplies a stable voltage. A stable voltage is about the only reason
beyond weight and size I can think of for paying that much.

Please point me to an example of an active electronics (lightweight)
marine isolation transformer.

Here's one:

It may not cost enough to qualify for "marine status" but just double
the price and it might work.
