Recently purchased this 1959 14' Starcraft v-bottom for a great price. Boat is in great shap well taken care of. Would like to add a floor deck and upper front deck. I plan on removing the back and center benches and replacing them with normal fishing chairs for more room to maneuver. I've been looking at lots of people's build on here but don't know where to start. How thick plywood do I need, where do I screw to down too and many other questions I have. If anyone has a quick tip please reply, would love all the help I can get. Tight lines everyone
