History Meets Technology at the Gloucester Marine Railways From Kathy Chapman
Andrew Williams of 3D Measure is performing a 3D laser scan on the National Historic Landmark Schooner Adventure, which was built in 1926, in Essex, Massachusetts, by the John F. James and Son Shipyard.
While a vessel is dry-docked, a laser measure can be made of the outside of the hull and deck, collecting "as-built" data. This data is then turned into a 3D surface model.
Naval Architects John and Fritz Koopman of Propulsion Data Systems of Marblehead will then use the 3D model together with an internal scan to produce a stability calculations, tonnage and other documentation which can be submitted to the US Coast Guard.
