Stable Stand – a retrofit platform on boats that keeps still on rocky seas

The idea here is simple: Drones were enabled by fast, small, efficient processing. They physics was always known, what happened is that computers became fast enough to process events and respond to them to enable a drone to alter things to keep itself more or less hovering. So can we use the same sort of technology to create a stable platform on a rocky boat? Think of a 2 people sized bucket, which sits on a single point, and then has a bunch of motors on each side of the bucket that essentially tip the bucket one way or another. Then a heap of sensors on the boat that can detect when it starts to move and tell the bucket to compensate.
