Summer Bikini Beach Girls Recreate On Yacht Vessels

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.
Hull types
Monohull yachts are typically fitted with a fixed keel or a centerboard (adjustable keel) below the waterline to counterbalance the overturning force of wind on the vessel's sails. Multihull yachts use two hulls (catamarans) or three (trimarans) widely separated from each other to provide a stable base that resists overturning and allows for sailing in shallower waters than most keeled monohulls.
