RE: Sampson Post & Capstan
I remember your ( Charles') trick with the chain and made sure I picked up a length at the first marina dumpster that had some.
I broke a trip line on a Bruce and had to cut the chain below a bridge on the TennTom. I suspect trees as I had previously dove in clear water on the same snagged anchor and saw how those side wings would bite into a snag. On reflection, a retrieval hole closer to the base of the flukes might help rotate the flukes out, or, at least give a fairer lead for a backwards pull.
Anchoring in coral in the Pacific, I made up a weighted slider that was tied in the bight of the trip line leading to the buoy. This,with a 50 ft. line, gave me a 25 to 50 ft. Depth range, and worked well. The only anchor I lost on that trip was in High Peak island, where, of course, I hadn't attached the trip line, nor a rode buoy, and the rode chafed thru.
