Gem Air-Sea Systems Ltd has been manufacturing custom made Marine Lifting Slings/Bridles for Rigid Hull inflatable boats for over fifteen years.

Our Slings/Bridles are manufactured from Heavy Duty Polyester or Nylon Web, from 1” to 4” wide depending upon the configuration and SWL of the boat.

Gem air-Sea Systems Ltd uses a custom designed Pear Shaped S/S Welded Ring that has been NDT Tested and Certified. We also Electro Polish the Ring for an enhanced appearance.


Our Slings/Bridles are manufactured using 1” leather or nylon reinforced eyes and sewn directly to the S/S Ring. The bottom legs are also reinforced with leather or nylon eyes and marked with either FWD or AFT tags. Each Sling/Bridle is sent for Certification after manufacture and “Pull Tested” to 200 % of the SWL per Leg. A copy of the certification is provided with each sling as well as a copy of the NDT Weld Test.
