Cute Young Dark Blonde Girl On The Small Yacht At The Sea

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.
