The most popular plans for making up your own Dual Planer Boards posted on most Websites and shown in Fishing Magazines as linked below are the same plans and instructions. http://www.quintefishing.com/make_your_ ... boards.htm http://www.straitlineanglers.com/Articl ... Boards.htm I made up the same pair but the problem I have especially trolling for Walleye at slower speeds is that I find that they tend to drag about 45 Deg off of the corner of the boat rather than off the side of the boat. I also found plans for 1 x 8 dual planer boards. Great if your boat has lots of room. IDEA! Make up a removable 2-3 Bolt (to hold in place) Sailboat Keel shaped (same length as board) with 1/4 inch or less Aluminium plate either angled on nose same as boards or ground to a point on from both sides. You could space 2 or 3 Bolts (siliconed) around 2 Inches from bottom using Wing Nuts. You would have to experiment to see what works better in attaching (the Inside or Outer Board). I will be making this up myself this Spring. Has any fellow fisherman made up anything similar or can you add other ideas to get more pull.
