Abstract: A system is provided for automatically opening and closing a two-part longitudinally hinged longitudinal cover for a swim spa. The automatic swim spa cover opening and closing system is characterized by a longitudinal support that spans between and along longitudinal ends of the two cover parts, first and second drive mechanisms disposed on opposite longitudinal ends of the swim spa, a first drive arm operatively connected to and between the first drive mechanism and a first end of the longitudinal support, and a second drive arm operatively connected to and between the second drive mechanism and a second end of the longitudinal support. The drive mechanisms each include a hydraulic cylinder operating configured drive gearing that operates configured drive arm gearing. The drive and arm gearing provide a two-stage operation of the drive arm to separately pivot the two cover parts for opening and closing the two-part swim spa cover.
