Jon Boat Mods - Do's and Don'ts - Bass Boats, Canoes, Kayaks and ...MarVaBC 0. Catch, Photo, Release; MarVaBC; Members; 0; 111 posts; Location Central Maryland. Report post. Posted December 28, 2006. I am thinking of doing some modifications to a 16x48 jon boat. Are there any must do's or must don'ts I should know about before I get started? I just basically want to make a deck in the front with some compartments underneath, and a deck to cover the back battery area. Any info on what materials work best would be greatly appreciated as well!
