Although there are other practical reasons to have two devices I don't think the power source of the receptacles applies. Even if the two power circuits have a selector switch the ground / earth conductor in not switched and almost certainly common across both on the boat. Thus your boat bridges the ground circuit of the two incoming power receptacles but they would likely share a common ground at or near the dock in any case. As the isolator is in-line of the grounding conductor one properly sized device could, where installation is practical, handle both power receptacles.
