A craft from the highly anomalous Cabochon series of non-aerial vehicles, the Chabochon Chaindriver, Chabochon & Kite, or simply Chaindriver, features a buoy and a thruster-powered, wingless kite. It's quite awesome, but it'll take some getting used to to drive. It's colored to help you.

Directions: Quick, turn the throttle up to above 10%, but below 50% (unless you hate the seas, in which case go ahead; void your warranty and take off like I accidentally have multiple times) so your kite doesn't swamp the Chabochon!
To drive the X-11 Chabochon Chaindriver Buoy, use PITCH and ROLL to go along the various, color-coded axes (by tipping the kite and tugging the Chabochon.) Don't get yourself killed. If you need to manually override the Chabochon direct stabilizers, activate [7], but you'll void your warranty.
