I was like you , always seeing all the other boats using planers and wondering. Well I decided to build a pair. Though we still cautch a lot of fish of the sides and back of the boat , we also catch a lot of fish on the planer boards. At least one fish on every trip is caught off the planers. I troll to lines on each side with them and do think that it helps you catch more fish. If I can find the site that I got the blueprints off of I will send it to you. They are not difficult to build.
