Douglas Marine Cardan Mooring Device

Manufactured in Italy from marine grade stainless steel HR.

Douglas Marine are proud to produce a mooring spring complete with an enhanced cardan rotation device featuring rotating heads at each end bedded on stainless steel ball bearings.

Cardan Mooring Spring Device Plus Factors:

• Rotating Head on stainless steel ball bearings - the Cardan function is essentially a universal joint at both ends of the spring which allows the spring to rotate independently of the connecting shackles preventing the attached mooring lines or chains from twisting.
• Special nylon head design:

• Balanced Load bearing capacity - the Cardan shaft design ensures that the spring flexes in and out in perfect symmetry with the internal parallel load bars.
• Excellent articulation from shackle end connectors.
• No need to purchase extra shackles - there is one incorporated in to the design.
• Rated Manufacturer Break Load.

Douglas Marine publish a manufacturer minimum break load for reassurance:

Jimmy Green Rigging Team Advisory

1. Attach a slack warp alongside the spring as a security measure.
2. Deploy a second, independent mooring line for reassurance.

These precautions are especially important when the yacht is left unattended for long periods.
