The prompt

A structural aluminum skeletal frame assembly for a 3658 mm long by 914 mm wide Jon boat hull interior. Made from 38.1 mm x 38.1 mm x 3.175 mm angle stock and 25.4 mm x 25.4 mm x 3.175 mm square tubing. The frame consists of: 1) A 914 mm long raised front casting deck frame elevated 305 mm high with three longitudinal support stringers. 2) A 1219 mm long by 254 mm wide by 305 mm high side gun box skeleton frame attached along the starboard wall. 3) Four parallel 25.4 mm floor stringers running longitudinally across five transverse floor ribs. 4) Two 45-degree stern transom knee braces made from 38.1 mm square tube with 4.76 mm triangular gusset plates. 5) A 343 mm x 190 mm x 50.8 mm battery tray frame on the port stern corner. 6) A 520 mm x 343 mm x 76 mm fuel tank cage raised 25.4 mm off the floor on the starboard stern corner with a vertical aluminum divider plate. 7) A 152 mm x 203 mm x 3.175 mm flat bilge pump mounting plate centered over the keel 50.8 mm forward of the transom and elevated 12.7 mm off the bottom hull.
