[Rhodes22-list] Anchor Chain Question

Sat Mar 19 11:45:57 EST 2005

Roger,

I agree chain has it uses. However there is not much need for chain when 
anchoring in Bill's local waters. I suggested he use chain when on the coast 
or traveling to areas with unknown bottom. If I were traveling to different 
waters I would bring my chain but experience has taught me it is not needed 
for my local hang outs.

Not using chain has nothing to do with lack of physical ability. I am quite 
fit; I just don't like hauling up chain coated with red mud/clay. More 
importantly my boat holds quite fast without chain. I have learned a few 
things spending a hundred plus nights on the river. One lesson learned; I 
don't need chain. I check for chafe but I don't have any. No worries.

I typically anchor in 6 feet of water in coves surrounded by trees and 
hills. Very much like the area Bill sails locally. If a heavy storm rolls in 
I could quickly rig second anchor if needed. My single cheap anchor has 
always held just fine. This includes riding out summer thunderstorms and 
winter Noreasters.

Your tip sheet is good advice but it does not apply to all bottoms. If you 
want to mess with chain even in areas that don't require go for it. Me I 
would rather not have to re-dip the anchor a mess of time to try to clean 
off stubborn red clay. A bunch of folks at my marina told me the same thing. 
"Oh it will not hold, you will chafe problems." Guess what? They were wrong!

So I am off to the lake for the night. And no I will not have a single link 
of chain with me!

Wally
