Mine would be as would the OP’sThe electrical regulations state all 230 volt sockets ie blue on the same pedestal must be the same phase , all red are 3Phase , but very rare in uk mainly for super yachts or commercial fleet. There will be no boats with two plugs that are connected on board. It’s just a what if idea, and if some dick did this they would pay the price.
edit sorry I may have misunderstood you you meant “connected together onboard” I think so yes I agree
