I don't think the G-man is "talking" to anyone with a 72' Burger.
I think his show's target audience is the weekend boater.

I dunno, if I had a 72' Burger, you could bet your ass I'd be on it every
weekend, and would probably be watching "G" man on the weekends on a large
plasma screen in the salon being fed by the onboard sat TV system. But
alas, such is not my fate.


I also think the primary variable here is more the depth of the water,
hence
the angle of the rhode(I think that's the correct word) more than the
size of the boat. (when your talking about boats between 14' - 32').
Anything larger would probably need a little more chain and a
larger anchor.


Water depth is indeed a primary variable, and it dictates scope, the length
of total rode employed, expressed as a multiple of depth. Anchor size and,
in my opinion, chain length are driven primarily by vessel size.
