Have you actually tried a Spade anchor yourself? I'm swinging a 60,000
lb trawler on one right now as we speak, in 20 kt winds and marginal
bottom conditions. Had one on my old boat and liked it so well that I
bought another one for the GB49.

No one anchor is perfect for all conditions but the Spade is the best
overall that I've ever used, and I've tried just about all of them at
one time or another.

Just a satisfied (repeat) customer.
