A human-powered watercraft may include a frame, a forward hydrofoil attached to the frame, and a first rear hydrofoil attached to a first strut with the first strut rotatably attached to the frame at a pivot point and the first rear hydrofoil configured to pivot about a rear end of the first strut. A method for roller swaging may include inserting a tube end into a ferrule, and urging a spherical roller against an inner wall of the tube with a force sufficient to swage the inner wall against the ferrule, thereby mechanically securing the ferrule to the end of the tube. The method further includes modifying a quality of result statistic for the document as a search result for the query by a factor based on the one or more time trend statistics. Subsequently, the computer system may receive, from the customer portal computing platform, the one or more security preferences associated with the customer. The wireless control further includes a unique code for validating speed commands and initiates deceleration if the control signal is lost.
