Thanks, Art, It's useful to me.
I had forgotten.
It fits with Rod's system, and I'm looking forward to playing with it on
my boat.

> The attention on anchoring technique is valuable for all of us. You and I swapped an idea a few years ago, maybe valuable in this dialogue. I work from the cockpit, and want to avoid a necessity of moving to the foredeck during anchoring. The anchor line will terminate at the bow cleat, but I add a line (~25'), call it a 'set line', lighter than the anchor line, and fix it to a snatch block, through which the anchor line is eventually threaded. With anchor deployed and set from the stern, and the anchor line still held from the cockpit, I slip the snatch block over the anchor line. When I am ready to change anchoring orientation from stern to bow, I can slowly let out about 20' of the 'set line' until the bow turns into the wind. I can leave the snatch block in place, or unclip it from around the anchor line until I want to reverse the process and raise the anchor. It is obviously important that both anchor line and 'set line' are outside the shrouds and cannot tangle!
