I should have known better. The slough where I dropped anchor for the night was among the many tidal backwaters of the Snohomish River near Everett, Washington. The sloughs were littered with waterlogged driftwood, some of it exposed at low tide, the rest permanently submerged. I dropped my expensive stainless-steel anchor for the night and in the morning it was truly stuck. I spent over two hours trying to free it, using brute force and every trick I knew, and ultimately had to cut it free. It was the only time I’d lost an anchor and I wanted to make sure I’d never lose another.
The method that I’ve occasionally used to make suer I don’t lose an anchor is to tie a retrieval line to the anchor’s crown and the other end of the line to a small buoy, before I drop the anchor. If the anchor gets hung up and won’t follow the rode up, the buoyed line will pull it backward out of the jam.
Using a retrieval line isn’t as convenient as using a single rode and its chain, so I looked on the Web for other ways to pull an anchor out of a jam. What I found were variations on a theme: connecting the end of the chain to the crown of the anchor and applying a breakable connection between the eye of the anchor and the chain that parallels the shank and passes by the eye.
Many anchors have a hole at the crown for a line to pull the anchor backward, but neither of my two Danforth anchors do. A search on the Web turned up only a few photographs of Danforths with holes in the rectangular plates at the crown and one drawing showing a “tripping ring” secured between those plates. I drilled 1/4″ holes in the plates of one of my Danforths and inserted a bent stainless-steel bolt as a tripping bar.
The most common breakable connections I found in my research were plastic cable ties. One YouTuber suggested twine, but wasn’t clear how thin or how thick it should be. Cable ties come labeled with their breaking strength, so it’s possible to find an appropriate size that can hold the anchor head securely yet be consistently within your abilities to break and free a stuck anchor.
I also found my way to the Anchor Trip Link from the U.K. It’s a 5″-long chain link, split at one end and equipped with a slider that adjusts to hold the split ends together or separate them. After the end of the anchor chain is secured to the crown of the anchor, the Trip Link is inserted into the anchor chain and the split ends are closed over a shackle in the anchor’s eye. The Trip Link holds a bit of slack in the chain paralleling the shank so the strain on the chain goes directly through the link to the anchor. The slider determines how much force is required to pull the shackle through the split.
My tests at home were quite promising. I could pull hard on the rode, and with the chain parallel with the anchor shank, there was little strain on the cable tie. And yet I could step on the anchor flukes, snap the chain, and break the tie. The Anchor Trip Link performed well too with the same tests.
When I went to the beach for some low-tide trials, the Mantus, my deepest-digging anchor, got off to a good start. It did well with the cable-tie method, and I could set the anchor and change the direction of pull without breaking the tie. The Danforth did the same thing in the sand, but on one trial over rocks, the tips of the flukes got hung up and didn’t penetrate the ground. That made the crown rise, and created enough of an angle in the chain to put a strain on the tie and break it. On another trial, the chain was beneath the Danforth’s shank and prevented the flukes from pivoting into the sand; the anchor just skidded. The claw anchor, which I never use because it seems unable to get a good purchase on sand, surprisingly released the tie when I changed the direction of pull. That surprised me because the claw offered so little resistance. I don’t know if the tie broke or if its ratchet failed; either way, it wasn’t a point in the favor of cable ties.
To simulate a scenario where the anchor was stuck, I slipped the Danforth in between some driftwood logs and pulled the rode at an angle that put the strain on the tie. The chain had to curve a bit over one log, and while that seemed to reduce the pull on the tie only slightly, I couldn’t break the tie. I also tested the tie at the end of 75′ of 7/16″ nylon anchor rode. There was so much stretch in the rode, about 6′, that the tie never got a sudden, sharp jerk. I couldn’t break the tie that way, but when I removed the anchor from the logs and stepped on the flukes, one sharp pull on the chain snapped the tie.
I tried the same log-snag test with the Anchor Trip Link. On two trials, the link got fouled on the anchor shank in such a way that the split couldn’t be put under strain and release the shackle.
I was at the beach conducting trials for less than two hours and yet in that short time I experienced several different and unexpected fails. I suppose with practice I could make the release systems work better, but I didn’t have faith it would be enough to overcome Murphy’s Law. And anchoring late in the day, tired and in the fading evening light, is not the time for using a finicky system.
I’ll continue using the separate anchor retrieval line. With enough scope, it’ll keep a buoy from pulling up on an anchor in a rising tide. A floating polypropylene braided line, the kind used for rescue throw ropes and dinghy painters keeps the line from getting tangled on any snags on the bottom.
