[C38] Dock Lines

Wed Aug 19 00:33:16 EDT 2009

I'd be interested in learning about the can't-miss docking procedure.

I recently took a class on splicing and was amazed to learn how much a knot
(i.e. bowline) decreases line strength versus a splice..I believe it was/is
30 to 40 %.

During a particularly rough Nov-Dec stay in Marina la Paz, in 1996 we broke
five 1/2 dock lines in 4 days. Most fellow sailors were having the same sort
of experience.

After talking to more experienced cruisers, I made 2 fixes, using 5/8"
3-strand nylon with plastic water hose chafe protection spliced into the
eyes for the boat cleats:

1)  For my every-day, general-use lines, I simply cut the spliced lengths
slightly longer than the boat length, heat-sealed and siezed at the running
end.  (These lengths provide for tossing and handling by dock-side crew
under almost any docking situation).  These lines are still in use on
SnowBird, today.

2)  For the fitted lines for our particular slip, (again, with plastic water
hose chafe protection spliced into the eyes) I installed rubber snubbers,
then--measuring the proper length--I spliced aluminum eyes into the dockside
ends.  These were secured with short pieces of 1/4" chain, looped around the
dock cleat and secured with a clevis through the aluminum eye.   Never have
had a dock line failure since.

As an aside, the new slip lines, bow and stern were run to a dock cleat
midships, with 2 midline boat breast lines led to dock cleats forward and
aft.  This provided more line stretch & boat movement and eliminated the
hard shock of slamming against the end of a short line.

For those interested, Cupcakes and I also developed a can't-miss docking
procedure some may have seen, but of some interest, in any case.

Advise if you want me to share.

Larry, 

I just used 1/2 golden braid and spliced eyes using a splicing tool and
sewed leather for chafe protection.   If you do this yourself a tip on the
splicing is at the end when you have to pull the jacket down.  I wrapped the
eye on a cleat and put the tail on a winch that made the process a heck of
alot  easier.

Larry,
    We prefer 1/2 inch nylon so they will have some stretch and not transmit
loads to the boat. Chaffing is easy - just slip clear plastic tubing over
the lines. Joe Launie/Macavity

What is the recommended size for dock lines for our boats?  West Marine has
them on sale and I was thinking about buying some new ones, the ones we have
now are pretty chaffed, any hints on avoiding chaffing?
