Hi Tommy!

No, no real story behind the moniker. “Bubblehead” is how submarine sailors are known, and I spent a large part of my life as a bubblehead.

Once a sub submerges, there is no outside frame of reference, so control of the boat largely relies on the clinometer. A clinometer is a sort of level, with a curved tube filled with liquid and an air bubble mounted on a calibrated plaque. When going deeper, you might give the order, “Give me three degrees down bubble”, and when you want a stable platform you would say for example, “Make your depth two hundred feet, maintain a zero bubble”. Of course there’s now modern electronic technologies for trimming the boat (and everything else, for that matter), but there’s still clinometers mounted on various bulkheads. So the ‘bubble’ becomes an important thing in our lives.
Amazing what we learn here. Sometimes guitar related also. :p:D
