I am going to test some anchors on our August trip to the BVI. This is
the second test and I learned a lot on the first one about what to do to make it more accurate. To measure the set distance I need some means of marking exactly the location that the anchor was dropped. I am invisioning some sort of pointed weight with a boyant shaft that can be dropped as the anchor is released. A float on a line will also give me a refference point for the next test so I can be sure each anchor lands in similar bottom. Anyone ever seen such a device or have a better idea? -- Glenn Ashmore I'm building a 45' cutter in strip/composite.

Adjust the length of the line so the bobber is just starting to be pulled under to ensure accurate positioning. |

Ever try to pack a concrete block? :-) I need something that will drop
straight and fast and most of all I can pack without adding much weight. I am already carrying 110 pounds of anchors and need a little room for a bathing suit and a toothbrush, :-) Wayne.B wrote: On Tue, 27 Apr 2004 16:32:57 -0400, Glenn Ashmore wrote: Anyone ever seen such a device or have a better idea? ================================================== This would be sort of expensive and hi-tech, but how about a fishing bobber tied to a concrete block with monofilament line?

You could start off with the ball from a trailer hitch (simple and cheap), or work your way up thru large lead sinkers and the monofilament that Wayne mentioned. -- "All we are given is possibilities -- to make ourselves one thing or another." -- Ortega y Gasset |

I kinda like the trailer knobs and adjustable fishing bobbers. I have
accumulated several GPS units so getting back to the same general place will not be a problem but these test have gotten a bit more complicated than I first thought. last time we just duplicated the Practical Sailor tests and got pretty much the same results. This time I want to measure creep under loads 10-15% below where they drag, how far they sail from the drop point and get more accurate mesurements on how far they take to set. A lot of that requires mesurements in inches. All this may seem a bit over the top but if I am selling these things I want to know everything about them. Besides, I made a little profit on the anchors last year and need to be able to show the tax man that 10 days in the BVI is a legitimate business expense. ;-) Lew Hodgett wrote: "Glenn Ashmore" writes: Anyone ever seen such a device or have a better idea?
