I've hunted many times out of a big boat/open water. A trick I learned that works fairly well- think "crossing shots". Put the decoys out with the wind at your side so when the come into the decoys, you're off to the side, not directly in front. I'm convinced it makes a difference.

I rarely if ever hunt this boat alone...
The blocks are stored in order.... but the are taken out of storage and set on the gunnels... (or top of the decking)...then cast off in order, after the anchor is cast. Again... layout hunting or open water hunting with longlines is seldom a 1 man game.
