General Layout and Stats for M/V Möbius

The design for Möbius was created by the talented naval architect, Dennis Harjamaa of Artnautica Yacht Design, Inc. The design was created in the 3D modeling program Rhinoceros. When we were searching for a builder, Dennis produced these 2D drawings. While the model continued to be updated as the construction evolved,  we have not yet produced updated 2D ‘as built’ drawings of the entire layout. These drawings are not exactly as built, but close.
