From Evolution to Revolution

board a 160’ tridecker that had just dropped anchor, the intercom beeped in the wheelhouse. It was the owner’s wife, calling from the master suite and sounding a little queasy. “Captain,” she said, “I’m looking out of the window and the horizon is moving. Please do something about it.” The captain touched a button on the console. Around him every boat in sight was still pitching and rolling, but on the tridecker serenity reigned. Apart from the gentlest up-and-down motion it was almost as if the boat sat on dry land. This was because her captain had just activated technology’s latest—and by many accounts most effective—remedy for marine motion sickness: digitally-controlled stability at anchor.
