Windsurf Powered Tamanu

 

 

Klaus Riedl of Hamburg Germany built this Tamanu and powered it with a 10 sq meter (107 sq ft) windsurf sail.  Windsurf technology has been at the leading edge of sailing for a long time and it would be hard to imagine a more efficient sail.  Yes, I know a kite might be faster yet... unless you happen to need to go upwind.
