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.
That's topped out on a smooth lake with only two people on board. If you're referring to avg cruising speed, then the boat will avg about 28 MPH at 3200 RPM's I'm sure your the person that's been asking these questions for a Baja Islander 247. What will determine the overall performance of your boat will be the engine and out drive. Then the other factor will be the size and pitch of the prop. Your speed and performance will vary. The water and wind conditions affect the performance of the boat on every outing. On my 26' Express Cruiser I usually cruise at 22 MPH at 3200 RPM's, but on windy days, I can be going as slow as 16 MPH at the same engine speed.
