This is one of the most amazing DYI posts ever…
Our mooring lines are 20mm diameter Tipto Twelve and despite extra beefy double bollards serving as cleats on board, the line tends to clutter up the bollard. To allow the bollard to be freed up for additional use if needed, and to improve chafe protection and minimise creaking, I have just made several 8mm UHMWPE loops (2.5m circumference using Stealth Super 12) to loop around the cleats. The loops will be cow hitched to the eye splices on the ends of the mooring lines.
To give added chafe protection, I added UHMWPE covers to these loops.
It is dead easy to add covers on straight stretches of single braid line (just poke the line through the cover, then bury the cover in the core of the single braid and secured the junction with some whipping, similar to here:
This technique is not possible on loops (although with a bit of fiddling one end could possibly be buried this way) so I decided to use a tuck splice technique to secure the cover.
To tuck splice, the cover can simply be unbraided, divided into bundles and woven in a straight line up (as is done with 12 strand Tipto Twelve). Alternatively it can be woven in a helical pattern, following one strand of the single braid. Octoplait can also be tuck spliced either way.
I have played with both methods and found the helical pattern gives a much neater finish, particularly if the bundles of cover are first twisted together. So this is what I ended up doing.
I am not sure how many tucks are needed, but six seemed like the magic number given this wasn’t taking the full load.
