Van,
I may have posted this before, but rig your danforth breakway style, w/ the chain attached to the heel of the anchor then use zip ties to run the chain along the shank, so when you put pressure on it (w/ the ball or windlass) the ties break and the anchor slides out easily...
Also, dont need a huge ball/ rig... we use ~18lb danforth with 10' of chain and our ball rig is a big high test dogsnap over the line (have to pull a bit faster because it doesnt catch the anchor like the ring) and a medium sized fender... floated the anchor AND a lobster trawl last week with this (knew the F'er felt heavy

thought I was getting weak for a min) with no problem... IMHO, it's the only way to go... especially this time of year when the bow is a sheet of ice
my $0.02
