porpoised
Surfaced and submerged
Porpoised describes the motion of a vehicle—usually a boat, aircraft, or car—rising and plunging repeatedly like a porpoise breaching the water.
A speedboat porpoises when its bow bounces rhythmically off the surface.
In aviation, an aircraft porpoises during landing when it oscillates between nose-up and nose-down attitudes: The plane porpoised three times before the pilot recovered.
