A number of my fishing spots are in 150'-200' of water. Electric reels are
pretty much a "must have" thing, and if wind or current is running, 600' of
line is not excessive.

Unanchoring is fun, too, of course. We use a big flotation ball to "fly"
the anchor once it's loose, then go back along the streaming line and pick
it up and put it in the boat.
