Tiller Model Boats with Downriggers? in Open Lake Discussion Posted October 4 Here is a shot of my rig. 17' Mirrocraft with almost an 8' beam. Nice thing with this is the gunnels are super stout and handle tracks/riggers no problem. Other neat thing Mirrocraft does is spray the inside of the hull with a bedliner type material. Makes for a really quiet ride. Had this rig for 11 years and love it. We trailer and fish where the wind allows and pick our days on Lake Ontario.
