ive seen something like that before............we used to have a old flat bottom 10' we used to ferry our dirt bikes and atvs across the creek.
if you move that atv back some it becomes a nice lil ob..........i do recommend before you try that to make sure you have a strap across the front from gunwale to gunwale..............you dont even want to know how i know that.....but ill give you a clue: have you ever tried to tie a rope around the handlebars of a atv 10' under water??
The flooding seems to get worse every year, from what I read it isn't going to get any better . Look at the polar ice caps, shrinking at a faster rate than anticipated. Glad we have boats, maybe need bigger ones like waterworld?
