So...longitudinal axis... We talking rotating the ship in tight turns, doing a loop de loop, or a barrel roll? I need sleep and had an hours long test this morning, so a bit out of it.

I think none of your choices. longitudinal axis: spin around the long axis, like a hot dog in a convenience store heat machine. A barrel roll is closest among what you listed, but I gather that a barrel roll is a helix. Aileron roll is closer, because the plane can remain in a straight line as here

Unfortunately, aileron rolls got called "barrel rolls" in Star Fox 64 in a quote that became a meme. With a ship, this might be called a "death roll" or maybe repeat capsizing. The maritime authorities and survivors are rarely as impressed by it as one might expect.
