No
ac current
To operate a boat in Washington D.C., you are required to carry on board your Certificate of Number.

because they operate on DC
An AC water heater can be converted to operate on DC current but the cost will be large. In the electrical trade anything can be done if enough money is spent to get the results that are requested.
