Watercraft components that include a fluid system

A watercraft that includes a fluid system comprising:

• a hull having a bow and a stern;
• a sail disposed between the bow and the stern, the sail having a first end, a second end disposed on the hull, a lengthwise axis, a central axis, a first side, a second side opposably facing the first side, and defining an injection opening, a suction opening, and a channel, the lengthwise axis extending from the first end to the second end, the central axis disposed orthogonally to the lengthwise axis and between the first side and the second side, the suction opening disposed on the second side and between the injection opening and the first side, the channel extending from the suction opening to the injection opening such that fluid can travel into the suction opening and exit the injection opening;
• and
• a compressor disposed within the channel;
• wherein when said watercraft is traveling through a fluid the sail has a windward side and a leeward side;
• wherein the central axis divides the windward side and the leeward side;
• wherein the first side of the sail is disposed on the windward side;
• wherein the second side of the sail is disposed on the leeward side;
• and
• wherein the sail is rotatable relative to the hull such that the central axis continuously divides the windward side and the leeward side.

• a compressor disposed within the channel;
• wherein the injection opening is disposed on an injection opening axis disposed at a first angle relative to the central axis, the first angle being between about −5 degrees and about 20 degrees;
• and
• wherein the suction opening is disposed on a suction opening axis disposed at a second angle relative to the injection opening axis, the second angle being between about 10 degrees and about 270 degrees.
