A bit of trivia for folks, GabeN’s sub is named after a ship called the Limiting Factor from Iain M. Bank’s absolutely wonderful book, The Player of Games. All of the subs that Triton Submersibles make are named after ships in the Culture series of books. I’d highly recommend checking them out, although don’t start with Consider Phlebas, I consider The Player of Games to be a better entry point into the series.

Off topic, but I figured I’d share anyways.

EDIT: the SpaceX landing barges are also named after Culture ships.
