50amp plug vs two 30 amp plugs

My Bayliner 3988 was originally built with two 50 /125 inlets. The previous owner replaced the inlets with 30 / 125 probably for convenience when cruisng. I have now installed a single 50/125/250 inlet and carry several splitters as the 50/125/250 is the most common followed by the twin 30 amps setups. Nothing on my boat is 220 volt and I don't use a lot of power but when I heat in the winter the cord remains cool and
I have no fears of an inlet burning up due to an overload.
All wiring and breakers to the panel are sized to 50 amp and 6 ga. wire so all is well.
 
To answer the original question, plugging two 30 amp cords into a 50 amp adaptor is fine as long as u monitor ur amperage . I have roasted many adaptors drawing 60amps and no the breakers on the stations don't trip. Watch hill fire island is a perfect example . U never want to max out any cord rating or buy cheap electrical cords.

There are many different configurations for marine power and while it is true that years ago 50 amp 125 volt was somewhat common however it was a different plug and would be hard to confuse.

If he has a 240v 50a cord then he has two 50a 120v legs coming into the boat.

So when plugged into the two 30a receptacles he has a loss of 40a. Or 20a per leg. Assuming the boat is wired to use only the two 120v legs.
