[PSUBS-MAILIST] Deep Flight Dragon

[Alec Smyth via Personal_Submersibles]

I have to say one thing I wonder about is the function of that rear
spoiler. It certainly makes the vessel look more like a race car, but can
anyone think whether it actually serves a purpose? All I can think is that
because she's got positive buoyancy, the spoiler forces the boat under when
there's forward motion. It doesn't look like the spoiler pivots, and it
would seem cumbersome to make the down-force a function of forward
velocity.

Best,

Alec
