  • Patent number: 4416639
    Abstract: This invention is an improved dinghy for tending yachts and for similar purposes. The use and operation of dinghies usually entails various problems. In the prior art the managing of the loading of passengers and of gear, and at the same time maintaining a good rowing trim, has had numerous problems. The fixed oarlock sockets of the prior art have precluded efficient seating of passengers and the loading of gear, generally resulting in a poor rowing trim. At the same time, dinghies of the prior art have had less than an adequate bouyancy to enable the vessel to remain afloat in the event of a capsize. The present invention provides an adjustable oarlock device that improves the management of the loading of passengers and gear in a manner that results in an improved rowing trim. The dinghy is provided with a flotation collar, or pneumatic sponson, that provides positive bouyancy. The collar also adds stability by providing a righting moment when submerged, thus improving the safety characteristics.
