We wanted to
follow up on some of our popular newsletters from last spring and shed more
light on a few of them. Last April, we published an article named “When Should
I Replace My Standing Rigging?” which you can read in our blog archives at The
Crowley Advisor by clicking here.
As that
article mentions, regularly inspecting your rigging can be the key to finding a
standing riggings problem before they lead to a failure, which almost always
ends in disaster. We wanted to give you a few hints on how to conduct a DIY rigging
inspection, when to call in a professional, and the best way to save your
budget when it is time to replace the rigging.
The first step
is to get the mast down since you cannot conduct a proper standing rigging inspection
aloft. Sure, you can check what you can see on the standing rigging and the
running rigging, but without de-tensioning the rigging and some disassembly
there isn’t any way to inspect all the components of the standing rigging. In my
opinion, this can lead to a false belief that the rigging is okay, when in fact,
it may have serious damage.
The mast and
rigging should be visually inspected at least once a year and a thorough
inspection carried out by a professional rigger every 3 or 4 years. When inspecting the rigging the obvious
things to look out for are broken strands (pic 1), cracked swages (pic 2) and any fittings that
are producing a lot of rust staining. Rod
rigging requires a different approach to inspection as the rod heads are hidden
inside the terminals. We’ll cover this
in a future article.
The rigging
inspection form that we use at Crowley’s has over 30 check points on it
covering the mast, boom, vang and standing rigging. To see the full check list,
click here to go to our blog. Basically, it follows a mast from the top to the
bottom. We inspect every mast opening, sheave, attachment point, fastener and
light. We do the same thing on the wire; inspecting every piece from top to
bottom with special attention to the attachment points and turnbuckles. This
includes the chainplates which are often forgotten in a rigging inspection
since many people consider them part of the boat. It is important to inspect
every inch of the wire since a broken strand can be anywhere along the stay.
If you find a
problem or issue that you don’t feel comfortable with, it is time to call in a
professional rigger. When you find something that requires replacement, remember
that the entire standing rigging does not necessarily have to be replaced all
at once. Cables can be replaced in pairs
and this can often be done with the mast up.
For example, after 15 years the forestay and backstay can be replaced,
the upper shrouds the year after, and so on.
If a crack or broken strand is found on a particular stay, it is good
practice to replace its opposite number at the same time.
