Step 9: Mark positions of the remaining deck beams
Make a mark 24 inches from the bow and another 24 inches from the stern. Make another mark 1-1/2 inches toward the center of the gunwales. This will be the position of deck beams 1 and 11. Label them on each gunwale.
Space deck beams 2 and 3 evenly between deck beams 1 and the footbrace which is deck beam 4.
Space deck beam 5 halfway between deck beams 4, the foot brace and deck beam 6, the knee brace.
Space deck beams 8, 9 and 10 evenly between deck beam 7, the back brace and deck beam 11.
