[C320-list] anchor chain

[Morey Waltuck]

In Power Squadron we teach that the amount of scope depends on the anchor's 
ability to hold a particular type of bottom, considering wind and sea 
bottom. The scope will vary from about 5:1 in calm conditions to 10:1 in 
severe conditions. Normal is considered 7:1.  Don't forget to add the height 
of the bow of the boat and the highest tide when considering vertical depth. 
And, don't include the heavy chain in the calculations.

Do you need all chain for the kind of anchoring you say you do?

Gents,

I just disposed of my primary anchor chain.  It was 100 ft. long!  So rusty 
the rust was clogging up the locker drain. I think the bow may have risen 
two inches as well when I removed it!  My secondary anchor chain is 25 ft. 
What length is considered adequate for the primary?  I'm thinking 50 or 
70ft.

My anchoring is infrequent and in protected sounds or tidal creeks in 20 ft. 
or less of water. Usually for lunch or the random overnight.
