1. A sail-propelled wave energy converter, comprising:
a bulbous upper hull;
a tubular water channel descending from the bulbous upper hull;
a portion of the bulbous upper hull forming a pressurized gas accumulator in fluid communication with the tubular water channel;
a turbine power-take-off system adapted to generate electricity from pressurized gas; and
a rigid sail mounted to the bulbous upper hull, the rigid sail configured to propel the wave energy converter;
whereby water moving upwardly in the tubular water channel compresses gas in the pressurized gas accumulator; and
whereby pressurized gas in the pressurized gas accumulator is impelled through the turbine power-take-off system.
