I do crab/lobster fishing from a row boat.
I typically will lay a field of lobster traps in a 4x6 or 5x6 formation.
Usually, when I'm done with the last row, the first row is bobbing.
I then move to the first row and collect all of them and throw out the empty traps for another round and go to the next rows until I throw out the last empty trap in the last row.
If I haven't seen any *bob*, I'll toss the fishing line once or twice.
When I see a lobster trap bob, I start collecting them up from first tossed to last tossed.
At this point, I make a decision between opening up all the lobster traps and restarting the field as above, or I'll throw out the empty ones in a perimeter around my row boat up to 12 pots. If I get a *bob*, I pick up the previous traps laid along with the one bobbing, empty them, and toss them ahead of the last lobster trap tossed.
This usually makes the time go by a little quicker as I am usually moving about between picking up, emptying, and throwing.
I'm not sure if this is the best method or not, but it keeps me busy, and I rarely lose traps.
