How to Make a Flat Line Boom

A flat line boom can extend your fishing line to more productive waters. The horizontal arm prevents your line from getting tangled when making tight turns. This outrigger provides extra support when banking large fish, like a yellowfin tuna, which can "peel off 500 yards of 50-pound test line from a reel in less than 60 seconds -- something like snagging onto the back of a Mack truck speeding down the highway," according to TheJump.net, a website that focuses on fishing and deer hunting.

Instructions

    • 1

      Fasten an independent rod holder, with the hardware included, to the base of a 4- to 12-foot piece of lightweight anodized aluminum, about 4 inches from the end of the bar. Slide a lock tube into an existing rod holder on your boat.

      Screw a 1-inch eye hook into the aluminum, about an inch from the end, on the top side, opposite the rod holder. Slide the end of the aluminum with the rod holder into the lock tube mounted on your boat. Lock the boom in place in the extended position by tightening the lock boom with the directions provided in the lock boom kit.

      Slide your fishing pole into the rod holder attached to the aluminum boom. Thread your line through the eye hook at the opposite end of the boom that extends horizontally over the water, away from the boat. You can now troll in deeper waters with your flat line boom.
