145 (dinghy)
The 145 is a two person intermediate sailing dinghy complete with main, jib, spinnaker and trapeze. The class is a lengthened version of the 125 class of sailing dingy. The 145 class had a following within Australia, although not as strong as its smaller cousin. Eventually, the class fell out of popularity and the class associations disbanded in the early to mid 2000s. Some examples are still raced around Australia.

Monohull
right A monohull is a type of boat having only one 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 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 Romans, Phoenicians and Vikings. Modern ships carry tons of ballast in order to maintain their stability; even heavily laden cargo ships use ballast to optimize the distr ...
