planer board mast reel

[Bduck]

The first time I was involved fishing with planer boards was on Lake Superior 20yrs ago on a private 28' fishing boat that was loaded which had 6 electric downriggers and independent masts for each side of the boat. We ran 4 lines on downriggers & 3ea lines on each planer board for just 3 of us. If I were to use planer boards I would run independent masts. From what I have been seeing is a single mast either mounted fwd of the windshield in an open bow or just aft of the helm area centered in the boat.
I would say check eBay for supplies/parts needed for a mast.
