My point is that MedSailor is planning on a long tem cruise not simply a weekend here or there.
Get yourself down into the South Pacific where there are anchorages with depths of 100' and then pull the anchor up by hand.
For long term cruising in a 40 plus foot boat you need not only great ground tackle but a bloody efficient method of hauling the thing back up on deck.
We actually managed to hook onto a sunken trawler once. The part of the things bridge that came to the surface and had to be cut away from our anchor weighed well over a 100lbs. Without our lovingly repaired windlass I would never have got the thing to the surface and would have either been forced to cut the chain or stay hooked on and dive or get a diver to go down. Our windlass was able to bring it to the surface and hold it in place while I cut away the debris with bolt cutters.
