Abstract
A float () suitable for use as a buoy or as a component for a wave-powered vehicle. The float () includes an upper member () whose height can be changed and/or which remained substantially vertical even when the float is in wave-bearing water. A low drag cable () suitable for use as a tether in a wave-powered vehicle has a streamlined cross-section and includes a tensile member () near the front of the cross-section, at least one non-load-bearing member () behind the tensile member, and a polymeric jacket (). Wave-powered vehicles having a float (), a submerged swimmer () and a tether () connecting the float and the swimmer, include a means for determining whether the tether is twisted; or a means () for untwisting the tether; or a pressure-sensitive connection () which can disconnect the tether when the vehicle is dragged downwards by entanglement with a whale; or a 2-axis universal joint securing the tether to the float or to the swimmer; or elastic elements which absorb snap loads created by the tether; or two or more of these.
