Selector Switch for 2 Shore Power Suppies

[sail sfbay]

My powerboat has a midship starboard 50 amp 120v AC AND aft starboard OR aft port 30 amp 110v AC shore power connecions with a selector switch for 50 amp OR aft starboard 30 amp supply. I want to install a 120v AC 30 amp marine rotary selector switch with Off + 2 positions to switch between port and starboard. Found a Blue Sea 9009 2 position ("gen" and "shore") which is not really what I want since I do not want to switch to "gen", Baomain 2 position ("1", "2") switch and a Blue Sea 3 position ("1", "2", "3") switches. Two questions:

1. Are these switches rugged and safe enough or is there a better marine switch for this service?
2. Is there a marine OFF + 2 position switch without "gen" for this service?

What you want to do is exactly what these switches are made for, so yeah, they are goo for the application.

the gen is just a label. make your own label for shore and shore. the 9009 is fine.
