Mooring Line Size Guide - Suggested Size & Type by Boat Length
Specifying the correct size of mooring line for your boat not only provides the appropriate safety factor but can greatly improve onboard comfort.
Mooring lines cover a broad range of uses, from boat specific lengths custom made for your pontoon or mooring buoy, to anchoring, swinging moorings, tidal piers & rafting up.

- For faster, simpler & more secure mooring operations we recommend the addition of a long loop eye splice in the end of mooring ropes
- For mooring lines attached to other hardware such as shackles or mooring rings we recommend the addition of a stainless steel thimble on the spliced eye to reduce chafe and related ware.
- For swinging moorings we recommend Octoplait - an 8 plait rope which won't unravel as 3 strand does if your swivel gets jammed.
- Wash your ropes as frequently as you can to keep them supple and remove the damaging salt crystals.
