A towing apparatus has a spine with multiple generally parallel spine members extending in a longitudinal direction and having a length of at least 100 m, and with a leading end and a trailing end. A series of blades are mounted to the spine by couplers which allow the blade to rotate about an axis substantially transverse to the longitudinal direction, each blade having a first surface facing generally in the trailing end direction and a second surface facing generally in the leading end direction. Restraints prevent rotation of each blade by more than a pre-set amount towards the leading end, so that impingement of a wave on the first surface applies a force to the apparatus in the leading end direction. A pair of the towing apparatus' may be arranged to connect to a floating collector with a beach shape to collect floating debris on the sea surface, ridges helping to retain the debris on the slope until it is washed up into a channel.

Wave-powered towing apparatus

A wave energy converter has blades () on frames () rotating about a pivot joint () on a structure (). There is reciprocating rotary motion of the frame with respect to the structure, providing reciprocating rotary input power to a mechanism (). The mechanism () may be arranged so that the reciprocating input power is transferred to uni-directional power via pulleys () and sprag clutches ().
