roll your own tethers

Hey all, after passing out at the cost of tethers ($225 @ Fisheries!), I'm considering making my own. I understand that pinching pennies on safety gear could be false economy but I believe that you can make a tether that will keep you on the boat and without sacrificing safety and without coughing up >$200.

My idea is a length of line, with figure-eight loops on either end with the tails secured by overhand stoppers. Locking carabiners on both end loops. Then, somewhere in the middle on the line (actually positioned so one end of the line is 3' away and one end of the line is 6' away) put another loop with an alpine butterfly and attach a quick-release shackle to that loop. That should give me a nice double-ended tether.

I need to put some sort of padding on the caribiner for the 6' end so it doesn't scratch the deck. It would also be nice to find a positive locking 'biner with a quicker release than the screw release one. Still haven't found that.

I'm also interested in feedback on the safety of the knots and the breaking strength of the line. Both knots are pretty common in the climbing world which has similiar requirements to a tether. That's the reason I went with a figure eight loop over a bowline.

Anything to add? Am I missing something in the process?
