for example the equipment cost for a 10 kw wind turbine costs roughly $ 40000 while a 100 kw turbine can cost more than $ 350000 according to bergey com the average wind turbine can cost $ 48000 to $ 65000 to install
The boats can typically travel at speeds over 80 knots (150 km/h) in calm waters, over 50 knots (90 km/h) in choppy waters, and maintain 25 knots (47 km/h) in the average five to seven foot (1.5 to 2 m) Caribbean seas. They are heavy enough to cut through higher waves, although at a slower pace.
I'm trying to get an understanding of how fast a regular sailboat, not using power, traverses a wide body of ocean, both with and against a current. A rough order of magnitude for a lesiurely rate of speed is what I'm after here. As far as size goes, consider a private craft, again, under sail, not engine, maybe 30' - 40'. The idea would be a boat two people could crew and afford :).
