My bass boat has fwd and side sonar for depth and fish-finding. Hooking up a sonalert audio speaker might work for that container alert system idea. It scared me badly...another reason to never move at night. Being a merchant mariner would be fun, for a while I think. I met a guy in Panama that worked for Starkist tuna fleet...he was near insane.
