Donaghys Dockline Mooring Lines are double braided black nylon mooring lines that are softer and easier to handle, cleat and coil and are over 15% stronger than comparable three strand mooring lines. The water resistant coating prevents strength loss and weight gain when wet. Nylon is considered superior to other (and in most cases less expensive) types because of its shock absorbing properties.
Black Donaghys Docklines are less easily marked and do not discolour as white mooring (dock) lines tend to. Suitable for securing boats and dinghies to jetties, marinas, wharves, boat ramps, piles etc.
What size dockline?
The length, size, weight and type of boat, and just how exposed the docking location is, all need to be considered in choosing a dock line size. The following is a general guide, but windy or higher wave locations may require more heavier lines:
Boat Length
Dock Line Diameter
Up to 27' (8.2m)
3/8in (10mm)
28'-31' (8.5-9.4m)
7/16in (11mm)
32'-36' (9.7-11m)
1/2in (13mm)
37'-45' (11.3-13.7m)
5/8in (16mm)
46'-54' (14-16.5m)
3/4in (19mm)
55'-63- (16.8-19.2m)
7/8in (22mm)
64'-72' (19.5-21.9m)
1in (25mm)
Transient dock lines used as bow and stern lines should be
about 2/3 of the boat's length
Spring lines should equal the boat's length
Be sure to check the size and location of your boat's cleats
and chocks before selecting a dock line
High level of elongation provides for comfortable ride at mooring
