I have a few 12 volt circuits I would like to dummy proof by using a time delay type relay - I think its called a "INTERVAL ON" style - so meaning you flip the switch or press the button and the circuit is energized for a time period, perhaps one hour typically, then needs to be reset to turn back on.

I guess trying to simulate a building occupancy sensor (and maybe that's what I really should have)

but I am wondering specifically if anyone has any recommendations for these for a marine environment.
