![]() Cruising sailboats have more width, but performance climbs as they tend to be much longer with a starting over-all length of at least 25 feet (8 m) re-balancing the dynamic ratio between length of waterline (aiding speed) and beam width (adding cargo and people space).Daysailers tend to be wider across the beam and have greater accommodation space at the expense of speed.Larger trailerable sailboats include trailer sailers, which have enclosed accommodation, and sportboats which are optimised for speed.Racing dinghies and skiffs tend to be lighter, have more sail area, and may use a trapeze to allow one or both crewmembers to suspend themselves over the water for additional stability. Small sailboats also called dinghys are commonly made from fiberglass, and will have wood, aluminum, or carbon-fiber spars, and generally a sloop rig (two sails: a mainsail and a jib, commonly include 3rd sail the spinnaker for going downwind).Sailing can be either competitive, as in collegiate dinghy racing, or purely recreational as when sailing on a lake with family or friends.Rowboats are generally heavy craft compared to other has Row boats or dinghies are oar powered, and generally restricted to protected waters.The ratio of length of waterline to beam has much importance in marine mechanics and design. Rowing shells are extremely long and narrow, and are intended to convert as much of the rower's muscle power as possible into speed.Rowing craft are also popular for fishing, as a tender to a larger vessel, or as a competitive sport. Known for their maneuverability and seaworthiness, kayaks take many shapes depending on their desired use. Kayaks can be found on calm inland waters, whitewater rivers, and along the coasts in the oceans.They are also easy to portage, or carry overland around obstructions like rapids, or just down to the water from a car or cabin. ![]()
