Submarines, the magnificent underwater vessels that have fascinated us for decades, come with their own set of peculiarities and nicknames. One such moniker is “Bubblehead.” The true origin of this term remains shrouded in mystery, with two prevailing theories. Some believe it harkens back to the old bell hat divers, while others associate it with the instrument called a Clinometer used onboard submarines. This device, utilizing a bubble of air within a curved vial of liquid, determines the submarine’s angle on its axis while submerged. Regardless of its origin, if “Bubblehead” is a term for submariners, then Dave Bryant is undoubtedly a Bubblehead himself. With 26 years spent either onboard a submarine or maintaining one pier-side, it’s a title that defines a significant part of his life.
