The problem I have noticed with folks fishing without 'riggers is that most of them flat line and let out way too much line, in the process getting tangled with the vast majority, who do use 'riggers. This fishery is crowded beyond belief, there is very little if any room to manouver, boats frequently have to pass within 30 to 40 feet or less of each other, and if you are flat lining - and even if you can maintain 45 degrees behind the boat you will be 70 feet back at 70 feet deep and will for all purposes be flat lining - expect to be hung up on other boats all the time. I keep my lines right under the boat and fish within less than 10 feet of my wires. So if you get within 70 feet of me and hang up I am NOT going to stop to untangle the mess - I run 4-6 dummy flashers and two lines on each rigger and pulling all that up to untangle something is going to take a half-hour out of my day. So expect to be snapped off unless you can stay at least 70 feet, or however far you are fishing behind the boat, away from boats fishing wire.
