J/121 Hull "Final Cut"

J/121 hull plug CNC- Symmetrix (Bristol, RI)- Progress continues on the creation of the latest 40-foot speedster from the J/Boats design team.  The amazing 5-axis CNC machine at Symmetrix in Bristol, RI  literally “cuts” the shape of the hull plug to an extraordinary accuracy of just 0.1mm!  It guarantees a perfectly symmetric hull shape as envisioned by the designers. The next step is having the hull hand-sanded with 800# sandpaper and then hand-polished to a mirror finish before it is coated with gelcoat and glass to create the hull mold.  Watch this 45-second time-lapse video of the “final cut” of the J/121 hull plug.
