With regards to two lines being used for fishing, this was a technique which was used with 3 anglers whereby 2 live bait lines were being run out the back and 2 anglers were alternating casts upfront. This would ensure that at any given time there was not more than 3 lines in the water for the 3 anglers in the boat. I had discussed this technique while fishing with a lawyer friend and was reassured that if done with the right intent, it would be legal.
Lol. As if.
