Hi, Steve.
Your song played right after Scott's "A Sound of Thunder", so for a moment I thought he had an FX tag at the end of his song.

Nice instrumental! Creative and fun to listen to.
I saw your response to Ray. Elvis Costello has some pretty amazing songs, and although the feel is different, "Shipbuilding" seems Costello's obvious nautical-related song. No submarine effects on it, but it's go Chet Baker on trumpet, so well worth the listen.
For submarine-themed songs with submarine inspired sounds, there's always Thomas Dolby's "One Of Our Submarines" and Al Stewart's "Life In Dark Water". So you're in good company here!
