How do you keep a chain hook from falling off the chain if the chain
goes slack during a wind shift? Most chain hooks I've seen are open ;or
does your chain hook have a clasp that locks it onto the chain? If so,
any recommendation for a source?

Subject: T&T: About anchor snubbers...about rolling hitch
Peter asks why not use a rolling hitch?
We have used it extensively on rope rode--since we use snubbers on rope
rode
as well as on the chain.
It boils down to it takes longer to get off the chain. Although it is
usually
easily untied, it can jam pretty tight if there has been a very high
load on
the rolling hitch. Chafe at the chain can be an issue--for example in
circumstances like the Cabo storm--one of my friends had used a rolling
hitch
on his stern line (which had a 22 # Danforth holding a 40 foot sailboat,
stern
too 55 knots of wind and 15 foot breakers.) and had chafe on the lines.
For us it is easier to put the chain hook on, and take off and that is
probably the biggest factor. We tend to let the hook set, feel the
chain/rode
as the boat comes back. Let it settle, then if it appears to be holding
give
a little power in reverse. Before the final power set, we put the chain
hook
on. If the anchor doesn't hold on the power set, we let out more scope,
or
then pull the hook and try a different place. The other side of easy,
is
less chance of injury when working around ground tackle and windlass.
When you are undoing a rolling hitch, you may be leaning over a bow
pulpit or
in a difficult position.
One other issue I had not mentioned: The grade of shackles: most people
buy
the cheap Chinese shakles. Shackles are the weakest link in the
anchoring
system. Shackles come in grades just like chain. You can buy up to
grade 80
shackles which are a high tensile strength steel--but may not be
galvanized.
Most shackles in marine stores say 1 1/2 tons or something like that,
but they
are often not proofed or tested. I have seen them fail.
