What is wrong with the current floor? Can it be repaired if holed? Unless you can find a pattern you are on your own for making a floor. Plus the side rails are probably not something that can be made cost effectively as a one off, if they are extruded aluminum. Buying one might be a better option. Found this on the web. "BoatU.S. 11.2 by Severn Boats: This 11-footer is the other model we looked at with a high-pressure Hypalon floor. Also available with either a roll-up hinged PVC floor or an interlocking plywood-panel floor, it’s the only boat in this group that offers the option of switching between three floor types. Because the floors are interchangeable, you could choose to carry more than one type of floor and switch them to suit the circumstances—air floor for inland excursions by car, wood floor for fishing the reef off Belize. The boat is made of Hypalon (Orca 828) and is sealed with double-butted seams, which use fabric glued along the inside as well as the outside of each seam to prevent any failure. The boat lacks the sheer of the others in this group, but the V is slightly deeper. Because of the selling power of BoatU.S., these boats are budget-friendly."
