Near-shore yachts typically range in size from length overall. Offshore yachts typically exceed length overall. Design Design considerations for a cruising yacht include seaworthiness, performance, sea kindliness, and cost of construction, as follows: Seaworthiness addresses the integrity of the vessel and its ability to stay afloat and shelter its crew in the conditions encountered. Performance hinges on a number of factors, including the waterline length (longer means faster), drag in the water (narrower hull with smooth appendages), hull shape, and sail shape and area. Sea kindliness is an indicator of steering ease, directional stability and quelling of motion induced by wind and waves. Multihulls offer tradeoffs as cruising sailboats, compared with monohulls. They may be catamarans or trimarans. They rely on form stability—having separate hulls far apart—for their resistance to capsize. Their advantages include greater: stability, speed, (for catamarans) living space, and shallower draft. Their drawbacks include: greater expenses, greater windage, more difficult tacking under sail, less load capacity, and more maneuvering room required because of their broad beam. They come with a variety of sleeping accommodations and (for catamarans) bridge-deck configurations. Rigs Gaff rigs have been uncommon in the construction of cruising boats, since the mid 20th century. More common rigs are Bermuda, fractional, cutter, and ketch. Occasionally employed rigs since then have been the yawl, schooner, wishbone, catboat. Gear Sailboats employ standing rigging to support the rig, running rigging to raise and adjust sails, cleats to secure lines, winches to work the sheets, and more than one anchor to secure the boat in harbor. A cruising yacht's deck usually has safety line to protect the crew from falling overboard and a bow pulpit to facilitate handling the jib and the anchor. In temperate climates, the cockpit may have a canvas windshield with see-through panels, called a "dodger". Steering may be either by tiller or wheel. Engine Cruising yachts have an auxiliary propulsion power unit to supplement the use of sails. Such power is inboard on the vessel and diesel, except for the smallest cruising boats, which may have an outboard gasoline motor. A sailboat might have a engine, whereas a sailboat might have a engine. Racing Racing yachts emphasize performance over comfort. World Sailing recognizes eleven classes of racing yacht. Design features High-performance rigs provide aerodynamic efficiency and hydrodynamically efficient hulls minimize drag through the water and sideways motion. Racing yachts have a wide selection of weights and
