anchoring

[chadsanchez]

so how long of a rope do I need for my box anchor and what is the best knot to use for it?

[tnvolgrad]

How deep of lake do run or rather how deep do you plan to anchor? I believe the box anchor is a 2:1 rope to depth ration where normal anchors are 3:1.

I would tie a bowline knot at the anchor.

I use either a bowline like said above or a figure eight follow through. Both will do the job :-) I don't have a working depth gauge so I have always just guessed on how much rope I need then I put a little more out. The box anchor has always held for me so I don't put much thought into it.

Bowline will untie itself with cyclic loading and unloading. Not considered a "safe" knot for climbing. Sooner or later you will pull up an empty rope. Better options are yosemite bowline or double grapevine. I prefer the double grapevine....that being said you will have to cut if off if you ever want to change things around. Again, standard bowline works great until it doesn't.

Even though box anchor said 2 – 1 (2 feet of rope for ever foot of water) this is a minimum. You can always use more rope. I drop the anchor based on the shore. I use 50 feet of rope and depending on the depth of the water depends on how far out I drop it. I keep the boat in about 4 feet of water and use a sand spike to tie the transom to the shore to keep the boat from moving. (I use an anchor buddy for the sand spike)
Also a fluke anchor is 5-1
