Be careful how you express this!

A 50 amp 124/240 volt outlet be thought of as two 50 amp 120 volt
circuits, or one 50 amp 240 volt circuit, or some combination thereof.

If your boat has 60 amps of 120 volt loads, you must ensure that no
more than 50 amps of that is on one "leg" of the 120/240 volt feed.
