The capsule’s oval shape allows for superior maneuverability in the water plus its beam to length ratio provides enhanced stability in rough seas.


When it reaches the water the design of SSI’s lifeboat also offers significant performance advantages related maneuverability and stability.

Due to its beam to length ratio and underwater configuration the capsule is significantly more maneuverable and canperform a 180° turn at speed within its own length.Due to their keeled-hull design and elongated shape twin-fall lifeboats are significantly less maneuverable and have toperform wide u-turns.

The SSI capsule’s maneuverability makes it easier to steer away from platform legs when evacuating in high seas. Additionally this maneuverability makes it easier for training and drills and in particular for positioning the capsule for hook-upand recovery. Lastly such maneuverability also makes a single cable capsule is a superior rescue boat for recovering aman over board.

SSI’s capsule has Greater Positive Stability than other lifeboats.The design and shape of the capsule provides a superior beam to length ratio, more than 0.65 (wider and shorter), anda greater metacentric height, in excess of 1 meter.These two factors significantly improve the capsules stability when underway. This greater stability makes the lifeboatless vulnerable to capsizing.
