An old dream....

Not new at all, but an interesting attempt to add vertical lift to be faster by fighting against gravity with a Wing-Sail and a "small narrow 15ft light-weight trimaran dinghy".

One of the forerunners was the famous "AEROSKIMMER"

I've posted this before, but it is a related idea that seems rather clever to me:

 

Really fast by lift from the kite and interesting steering in front (canard).

The small wingsail tri Zephyr is a brainchild from Tony Smith well known for his Trimarans and Catamarans (Telstar, Gemini and more). It has a very clever arangement to trim the profile and the angle of the sail. Therefore there is no need to reef .
