New Design Concept for Sailing Ship Mast
Boxed Ship Mast
A new design concept for sailing masts. I called it “Boxed Mast”. It is structurally and economically more sound than the conventional mast design; and it is also much better than the tripod design and the one used in The Maltese Falcon.
It also provides better energy-saving and safety from sinking and weight and materials reduction.
