Let me start by saying that I will not be posting any detailed pictures. I don't want to spoil any surprises. I have the first field ready prototype of this design completed and awaiting use. Thus far, I've completed scale tests and full scale proof-of-concept tests. Anywho... I thought I'd letch'all know what was cookin' in the kitchen. From a recent trip I took to a canyon with decidedly superfluous bolts, I was inspired, as others before me have been, to create an anchor that could be used when only water is present as an anchoring material. I knew that Tom and Jenny had been working on one but Im the type who wants to build one for myself regardless of what is available, maybe improving upon existing concepts or rethinking it completely. My latest project has been the latter. I came up with a different approach before I had even seen Tom and Jenny's idea. I talked to Tom and he mentioned some of the short comings of the current design. Wracking my brain I tried to think of all the possible scenarios in which this anchor might be used and any unforeseeable complications. I tried several ideas with scale testing, went back to the drawing board, and tested again. I finally settled on a concept that I felt was as simple as it could be, while also being more functional than any of my previous designs. It was so obvious that this was a much more effective and simpler design that I was a bit frustrated that I didn't see it sooner. I did some calculations to determine the dimensions I would need for it to hold ample water, and create enough surface area o provide the necessary friction. What I will say is that while modularity has a place in this type of engineering, there also comes a point when a purpose built unit is necessary to achieve a more satisfactory result. What that means is that this anchor works only for one thing: water anchoring. I thought about creating something that would act as an insert to a sand trap, but I was unable to achieve the levels of simplicity and functionality I desired. The whole unit rolls down to the size of a 1.5 liter Nalgene and weighs less than 2.5 pounds. When deployed in either of 2 configurations, low angle or high angle, (it can also be used on flat ground) it is capable of holding upwards of 200lbs of water. Once the pull cord is tugged and the mechanism released, all of my initial tests consistently achieved complete emptying of the unit in a matter of seconds, leaving only the weight of the empty anchor to be pulled down. Look for the Water Pocket to be making a splash in a canyon near you over the coming season. Taylor BTW Im rather proud of the name, a reference to a geological feature that most of you are familiar with.
