POWERSTOPPER™
POWERSTOPPER™ is a synthetic rope stopper for ship mooring operations. Its 12-strand construction combines polyester and high-modulus polyethylene (HMPE) to provide high strength, low elongation and the surface grip needed for temporary line holding. Abrasion resistance and low weight support handling at the mooring station.
Available in single-leg and double-leg configurations, POWERSTOPPER™ has a recommended length of 2–3 m, with optional thimbles and shackles to suit the specified connection arrangement.
It is used to maintain tension on a synthetic mooring line while the line is transferred from a warping drum or capstan to deck bitts. Matching the stopper assembly to the mooring line and vessel’s operating procedure supports controlled load transfer as the line is made fast.

How Does a Mooring Stopper Work?
During mooring operations, a loaded mooring line may need to be temporarily secured while the line is transferred between the winch and the vessel’s mooring fittings.
A synthetic mooring stopper is applied to the loaded line and secured to a suitable strong point. The stopper temporarily takes the load, allowing the crew to carry out the required mooring operation in a controlled manner.
The stopper should be selected according to the mooring line, expected load, rope construction, diameter, and applicable mooring procedures.
