Dick Dale era surf guitar (someone else mentioned this as well, adding the best artist name). Dick Dale also did a cover of Claude Debussy's "The Aquarium" which is the sound track for Space Mountain at Disneyland/World. So either or both, and there might be other covers of "The Aquarium" out there if the original isn't too slow.
Going more ocean-themed....
Aquabats or Tsunami Bomb for some early 2000s punk/ska that isn't ocean-themed but the bands are kinda.
Tide is High - Blondie
Scuba Diver - King Kong (it's a weird song, but hypnotic)
Where is My Mind - Pixies (about fish, but close enough)
Beyond the Sea by Bobby Darin
Maybe more sailing themed, but that's close, right?
Brandy by Looking Glass
My Heart Will Go On - there's a Dragonforce metal cover of this if you've been traumatized by the pennywhistle.
Come Sail Away - Styx
To be fair, telling people to scan QR codes with their phones is a huge phishing vector. I've seen a few places with new stickers over the first one, which is very easy to do. Is it an updated menu? Or a scam page for a session stealer?
