Task Force 72 (model boat builders)  Task Force 72 is an international association of Radio controlled model boat builders, all building in the common scale (ratio) of 1:72 (1 inch in 1:72 equals 72 inches or 6 feet in real life). Task Force 72 originated in Australia in 1994, when a number of individuals building radio controlled models came together to form a voluntary association. The name derives from the military term for a group of warships operating to a common purpose, a task force, and the scale of the ship models being built (1:72). In the years since, the association has grown from a small number of model builders to several hundred currently active and former members located in Australia, the United States, United Kingdom, Canada, New Zealand and several other countries. At this time the largest grouping of members is located within Australia, although it is hoped to grow membership internationally. The Association holds an annual regatta each year, normally at Wentworth Falls Lake, located in the Blue Mountains, west of Sydney in New South Wales, Australia. The Task Force 72 Annual Regatta is usually held in November or December of each calendar year. The 2018 Annual Regatta will be held on the weekend of Saturday 25 (10AM - 8PM) and Sunday 26 November (10AM - 4PM) at Naracoorte in South Australia. Two major prizes are awarded during the Regatta. The Bravo Zulu Award, named for the Naval flag hoist signifying 'well done', is awarded by a reviewing officer, usually but not always a serving member of the Royal Australian Navy. The Wentworth Shield is awarded to the model judged best by the members of Task Force 72 attending the Regatta. Several minor prizes are usually presented, including:  Best Warship;  Best Non-warship;  The Newbie Award for the best first model by a member; and  The Rob Sullivan Engineering Award for the most innovative engineering incorporated into a model.. Task Force 72 hopes that the Association's membership in other countries will grow to the point where they are large enough to support their own national regattas. Currently the majority of model ships owned by Task Force 72 members are military vessels however this is slowly changing as more non-warships are completed. In fact the joint winners of the Wentworth Shield for best model at the 2007 Annual Regatta were two non-warships, the lighthouse and navigation aids tender Cape Don and the USS Charles Robinson, a Liberty Ship. Similarly, the vessel voted best model of the 2008 Annual Regatta was a US Army Hospital Ship, the USAHS St Olaf which, while operated by the military, was not a warship.
