Steering a sailing boat might seem like a trivial matter, but it's not, it's actually a real science. World champion Roberto Ferrarese, in this video, explains the basic concepts of this science to enable us to make better use of our boat.
The video is part of the second season of Roberto Ferrarese's videos for SVN. In this second season there is, "How to steer the boat" which is the first to be released and "The tack and the shot" which will be the second to be put online.

The first season consists of three videos:
Adjusting the mainsail    • Regolare la randa  SVN IO Navigo  C...  
Adjusting the genoa    • Regolare il genoa  SVN IO Navigo  C...  
Adjusting the gennaker    • Regolare il gennaker  SVN IO Navigo ...  

The video was made thanks to the technical support of NSS Charter, the largest charter company in Italy and owner of the Cala dei Sardi marina.
