A turret mooring system 100 for a tidal turbine assembly 150 increases the ratio of the torque exerted by the turret 100 relative to frictional forces between the turret 100 and the assembly 150 moored to the turret 100. The turret 100 provides an upward force to the assembly, which also resists pitching moments of the turbine assembly 150. The upwards force may be provided by a lift-producing hydrodynamic surface of a chain table 104, which therefore creates an upwards force which increases with flow speed, and thereby counteracts pitching moments from the turbine 158.
