yes same purpose of a down rigger palnner but on the surface .. what you do is connect ur line to the board they put the port board on the port side.let it go out and attache it to a high place on ur boat. a place you can easily reach. same on starboard side. the boards are desihed to run away from the boat but the tension on the line will not let them cuaseing them to run along side of the boat them your take your clip. attach your line and let it run down the line. and we get 6 lines on 1 board. just like a 75ft outrigger.
