Parts of a Mooring
are estimates of how long mooring equipment will last based
upon our experience over the last 25 years in Marblehead. Please
keep in mind that these are estimates and many outside factors can lead to premature wear.
Because of this we can make no guarantee on the useful life of our
Chain will generally last for two seasons although
in rare cases can last as little as one season or as many as
three. We inspect all top chains in the fall and mark warn out
chains for replacement in the spring.
Chain can last anywhere from 4 to 10 years depending on the size of
the chain as well as the type of bottom it rests on. Rocky or
sandy locations tend to make the chain wear out sooner where
as a muddy bottom tends to make the chain last the longest.
We no longer use 1/2" bottom chains due to the fact that
they simply wear out too quickly.
top and middle Connection
Shackles are replaced along with the top chain, generally
every 2 years although may be replaced sooner if they show significant
wear during one of our two yearly inspections. Bottom shackles
are replaced with the bottom chain unless yearly inspections
show that they need replacement sooner.
Pennants generally last anywhere from 5 to 10 years if used properly
with chaffing gear in place. UV light as well as wear and tear
from storms and everyday use eventually break down the rope
and it can loose strength. The metal thimbles also begin to
wear out and when they become too thin, cause chaffing and failure
of the rope. Because of this we thoroughly inspect each set
of pennants in the fall before they are put away for the winter
and replace or repair them if necessary.
long a Mooring Buoy lasts depends on a large number of factors. While they can generally
last anywhere from 4 to 10 years, this can be cut short due
to storm damage.
Blocks generally last at least 15 years or more depending
on bottom conditions.
