Flix,
a 30 to 50 adaptor cord is not going to fix your issue... You need 220v not 110v. If you have 0nly 110 on the dock only way this is only going to work if there are 2 inidividual circuits (breakers not 2 outlets) ran to the dock on seperate breakers. Then you could convert both of them to 220 by using one leg from each 110 circuit. Most of the older docks in Newport and Huntington were 110 50amp old school for 50' foot and under. I know this well as I had my boat there and it was a 50 amp 110 90's style boat. NEMA stopped recommending 50 amp 110v on boats in the early - mid 90's hence when you saw dual 30 amp cords still on 110 boats. Hopefully you can find 2 seperate 30amp 110 breakers on your dock then you are in business and you can make a 220 circuit.
In addition to this, you not only would need two separate 30A outlets, but in order to get 220V they would also need to be fed from different hot legs / buses in the breaker panel. With single-phase power (what you have in your house and marina, and what your boat uses), hot-to-hot gives 220V (240V). Hot-to-neutral gives 110V (120V). Two 30A outlets that are fed from the same hot bus can't be converted to provide 220/240V.
Is anything on your boat 240V? Typical candidates would be the hot water heater, stove, maybe the air conditioning. Although my boat is also a 2008, it is an early production '08 and still has the 2x30A 120V shore power.
