The prompt
4. Longitudinal center beam and outer knees Center beam 4 layers × ¾″ marine plywood = 3″ thick Port and starboard knees 3 layers × ¾″ each = 2¼″ thick per knee Total layers 10 Knee lateral positions 13.5″ to port and starboard of centerline; 27″ center-to-center Length of each member 96″ overall: 30″ aft + 66″ forward of transom Aft section Follows bracket V-bottom; knees approximately 3.87″ shorter vertically than center beam due to lateral offset Forward height transition From full height at transom to available sole/stiffener height 10″ forward of transom Height beyond transition Center beam ~9.5″; each knee ~8.25″ working assumption (8–9″ expected) Forward taper Remaining 56″ tapers gradually to 3″ high at forward tip All members follow the owner’s drawn general profile: high within the bracket, smoothly reduced in the first 10″ forward of the transom, then long gradual taper. The center beam is intended to sit on the existing ~4″-wide center stiffener; the knees align with existing longitudinal supports. Verify actual fit and structural integrity before design finalization.
