Cute Young Blonde Girl With Blue Eyes Reveals Her Cyan Top And Jean Skirt Aboard A Yacht On The Sea

The motive force being the wind, sailing is more economical and environmentally friendly than any other means of propulsion. A hybrid type of vessel is a motor sailing yacht that can use either sail or propulsion (or both) as conditions dictate.
Many "pure" sailing yachts are also equipped with a low-power internal-combustion engine for use in conditions of calm and when entering or leaving difficult anchorages. Vessels less than 25 ft (8 m) (7 m) in length generally carry a petrol outboard-motor of between 5 and 40 horsepower (3.5 and 30 kW). Larger vessels have in-board diesel engines of between 20 and 100 horsepower (15 and 75 kW) depending on size. In the common 25 to 45-foot (7 to 14 m) class, engines of 20 to 40 horsepower are the most common.
