Note for Canadice
One way to keep the mooring lines from tangling on the buoy chain is to enclose the line in the stiffest garden hose you can find for the length of the mooring anchor chain or mooring line, whichever is shorter. That is, the vertical distance from the bottom of the buoy to the top of the mooring anchor OR the length of the mooring line. You can get the stiff hose and cut it longitudinally then fit it around the line. Unsightly? Yeah, maybe, unless you can find some white hose, but the stiffness keeps the line away from the bouy, if it does get twisted somehow, the hose allows the line to slip off the mooring anchor chain easily and is never under pressure. Result? No chafe at all. The rubber hose should last somewhere in the neighborhood of 200-300 years unless left in the sun.I also suspect Bryce's firehose would work well for this purpose also except that it is much heavier and may be much more difficult to install; still works great for the cleats at the bow though!
