I would like to get rid of the front/back seats on my 89 maxum 17 foot open bow. I wanna put in single captain chairs to free up some space, the boat is used primarily for fishing. Is the deck a solid piece under those seat boxes? Or should I just cut them halfway down, and mount the seats to the flat part that is already there. This would be ok, but it would be cool to have the deck totally flat so nobody would trip over what would be left of the seat bases. What I mean by "solid piece" is, is there a big rectangular hole where the bases are, or is it flat under there?
