This past weekend I launched my boat at the usual ramp and made my way out to the Delaware Bay. I noticed a number of fisherman on the jetty had cast there lines into the channel where the boats were running. The channel they were fishing has only about 4 ft. of water at low tide. I was making my way through the channel slowly giving anyone with a line in the water an opportunity to reel in. Well, I see 2 guys reel in and think I'm good to go. There was 1 guy left at the end of the jetty that had seen me coming and made no attempt to reel in. I figured his line must not be on my side of the jetty and since he had 3 rods in the water he must know what hes doing. Wrong, I managed to tangle his line around my motor, luckily not around my prop. I was able to shut the motor down quick enough to get his line off the motor but not before floating out of the channel and nearly into a channel marker. I was extra cautious since this was my first trip with the repaired lower unit not to tangle his line in my prop. I'm not the type of boater who feels as though just because they are in a boat they can zip through anywhere they want with no regard for others. This was not the first time I have encountered this situation and I'm sure not the last, but it is the first time I have gotten tangled. The fisherman looked at me like I was in the wrong for making them reel in, I just dont get it, maybe next time I'll just cut their line.
