This company is based in Scappoose, Oregon, USA, and specialises in the design and computer lofting of welded aluminium boats. Clients are both boatbuilding firms and individuals.

Supply is generally of the CAD data and drawings, with the option of supply of pre-cut plate parts. These are from stock designs or from client designs. Hull internals are built up using “egg crate” construction, notch to notch.
