Starling (dinghy)
The Starling is a New Zealand sailing dinghy designed by Des Townson. Origins of the Starling The Starling class yacht was conceived and the design commissioned by John Peet in the late 1960s. At the time, there were no single-handed boats available in New Zealand, for bridging the gap between the P-class sailing dinghy, P-class and the adult Finn (dinghy), Finn, OK (dinghy), OK, Cherokee and Zephyr (dinghy), Zephyr classes. Many young sailors were leaving the sport because the step to the adult classes was too great. A stepping stone class was required. In consultation with parents of current P-class sailors, a set of criteria was formulated for the proposed class: :* The boat should cater to teenagers or any one heavy enough to sail one that are not able to cope with adult monotypes. :* Crew weight could be approximately . :* The boat should be easily handled in fresh conditions, plane readily and have good windward performance. :* The appearance of the boat to be of high ...

Monohull
image:monohull.svg, right A monohull is a type of boat having only one hull (watercraft), hull, unlike multihulled boats which can have two or more individual hulls connected to one another. Fundamental concept Among the earliest hulls were simple logs, but these were generally unstable and tended to roll over easily. Hollowing out the logs into a dugout canoe doesn't help much unless the hollow section penetrates below the log's center of buoyancy, then a load carried low in the cavity actually stabilizes the craft. Adding weight or Sailing ballast, ballast to the bottom of the hull or as low as possible within the hull adds stability. Naval architects place the center of gravity substantially below the center of buoyancy; in most cases this can only be achieved by adding weight or ballast. The use of stones and other weights as ballast can be traced back to the Ancient Rome, Romans, Phoenicians and Vikings. Modern ships carry tons of ballast in order to maintain their stabil ...
