Abstract: An autonomous sailing vessel may include a hull, a mast, a sail, and a rudder. The mast may be mechanically coupled to the hull. The sail may be mechanically coupled to the mast. The rudder may be mechanically coupled to the hull. A heading of the autonomous sailing vessel may be regulated by actively controlling the rudder without actively controlling the sail. Alternatively or additionally, the autonomous sailing vessel may include an anticapsize stabilizer tank, a lidar system, and/or marine mammal monitoring and identification.

Abstract: An apparatus and method for control of at least one of a plurality of semiautonomous marine vessels are provided. The system includes a control station with a communications system for network communication with marine vessels, and provides diagnostics and control for control and monitoring of the marine vessels, according to a mission plan.

Abstract: A fleet of autonomous sailing vessels that are equipped with monitoring and communication equipment for reporting environmental and other conditions. For optimal stability, the autonomous sailing vessels are multi-hulled vessels (catamarans) with self-righting capabilities. Each sailing vessel sends and receives information via one or more satellite links, using solar power to power the communications equipment as well as the monitoring equipment. Each sailing vessel includes an auto-sailtrim system to maintain a desired attack angle with the wind, and electric propulsion for use as required to maintain a desired heading. A modular design is used to support mission-specific payloads.
