[Rhodes22-list] Anchoring -- Phuzzy Physics

Yeah,  Bill needs to add a disclaimer to his posts. Perhaps:

"This is my opinion. It totally ingnores all expert opinion and is
based on limited testing in specific circumstances.  Following
this advice may result in death dismemberment, or getting
wet when you least expect it. Follow this advice your own risk"

Bill,

There’s no way I’m an expert at anchoring, but I do know a bit about
mechanics and physics. You’re certainly right about an anchor’s generally 
sinking,
but the chain rode issue may be about  how the anchor engages the  bottom,
and stays engaged with the bottom -  not about sinking the  anchor. 
Consider an
anchor on the bottom with sufficient chain rode, if  there is a pull from 
the
anchor line with any vertical component, the weight of  the rode can
counteract the effect of the vertical pull and ensure  that forces on the 
anchor are
horizontal (i.e. notionally  parallel with the bottom).  I believe anchors 
are
really made to deal with  horizontal forces; the anchoring effect is 
achieved
primarily by  flukes, plows, or other appurtenances optimally engaging the
bottom, and  that requires horizontal forces.  Without the rode, any 
substantial
pull on  the anchor line that has a vertical component may cause the anchor 
to
lift  vertically, in which case it may not engage properly, or at all, with
the  bottom.
