My river anchor has the typical bar on top that, if snagged up, allows the chain to slide along the bar until it stops at the front of the anchor, allowing the anchor to release its self from the snag on bottom.
Unfortunately, on several occasions this release system has failed me. More specifically, anchor has gotten snagged up, pulled and pulled in different directions until finally it broke free, however in many cases the shackle did not slide up to the front of the anchor. In other words, the system did not work as intended.
And yes, I do know that to get the slider doing its thing you often have to let out a bunch of extra anchor line to get less of a sharp angle on the snag below.
Last fall got my anchor stuck BADDLY and was just about to give up and cut the rope. Pulled and pulled in all directions for about 30 min. Let out almost all my anchor rope (150 feet) to get a nice gradual angle and still it would not pop loose. Was worried I was going to bend my anchor cradle with the amount of lateral torque I was putting on it. Luckily it finally popped! Much to my surprise the anchor did not come out "backwards."
Anyway, I'm considering cutting the slider bar right off and welding on a chain link at the top and bottom of the anchor and going with the old school zap strap system. That is, on or two zap straps at the rear of the anchor affixing the anchor chain to the anchor. If you get snagged up, at least I am told, the zap strap(s) WILL break free and your anchor will release as intended.
It's not as pretty of a set up but I'm all for function over fashion. Any opinions? Do you think the zap strap system releases better than the slider bar?
