12m Aluminium Sail Catamaran Multichine Hull Architecture & Design A Rochian

Описание: 12 m ALUMINIUM SAIL CATAMARAN Architecture & Design A Rochian
Discover the full 3D design of my 12 m Aluminium Sail Catamaran — modeled in Rhino 3D with all internal frames, structure, and CNC cutting layouts.
This video showcases every structural element of the catamaran — from the aluminum framing to the precise CNC -cut panels, designed for efficient assembly and performance at sea.
