Semantics are always fun. In this case "float plan" (the term)
developed as an analogue to "flight plan" as required to be filed by
airplane pilots.

On the other hand, an airplane makes a flight but a boat makes a
voyage. An airplane flies but a boat doesn't necessarily float - see
submarine, unterseabot, etc.

errrr ... they DO float, just not on top of the water most times.



I'm not a submariner but I believe that much of the time they are
heavier then water at the depth they are navigating and have a
positive angle on the planes to maintain depth.


A modern military submarine tries to be as close to neutral buoyancy
as possible. But since exact neutral buoyancy is impossible, they
usually try to stay ever so slightly positive so that if something
happens and they lose control, they'll rise instead of sink.

Static uncontrolled rising and sinking is a positive feedback loop in
that as it sinks, the pressure goes up, the hull compresses and takes
up less water volume, becomes less buoyant, and the rate of sinking
becomes faster and faster. Not good. If it's initially positive
buoyant, as it rises, the rate of ascent becomes faster and faster.
Not nearly as bad as sinking faster and faster.
