"The Deep 6" is a nautical term meaning to discard something completely—typically by tossing it six fathoms down into the sea.

For this crew, it’s more than a phrase; it’s a mindset.
Six longtime friends have deep-sixed their ordinary lives to chase lost shipwrecks, diving headfirst into danger, history, and the unknown.
It’s a name that reflects both their mission and their willingness to risk everything for a shot at rewriting the past.
