Abstract: A vessel hull having a pair of vents formed in the chine on each side for allowing air to be introduced to the bottom and a pair of downwardly extending fins formed longitudinally along the chine adjacent to each vent. Each vent can be formed by a recess in the chine dividing the chine into a forward portion and an aft portion. Each fin is preferably formed longitudinally along the aft portion of the chine and extends below the waterline. The fins counterbalance the removal of a portion of the chine to vent the bottom and increase stability during turns. The hull preferably also includes a pair of chine extensions projecting aft of the transom on each side for reducing or eliminating side-to-side oscillation of the stern when the hull is propelled through the water at slow speeds.

Abstract: A condensed retractable traffic cone is a device designed to provide motorists with advance warning of disabled vehicles and/or work zone areas. The device has been designed to withstand reasonable winds through the use of two base supports, a lower portion, a retractable arm and a series of retractable vertical risers. The retractable vertical risers in combination with a retractable arm allow for the device to easily expand to height consistent with traffic engineering design standards when in operation and then compact when it is in storage. The two base supports are designed not only to provide the necessary structural stability but to also open and close about the retractable vertical risers thus providing for additional compactness. The vertical risers are designed with flexible hinges so that they may store flat and expand to a rectangular shape when the base supports are rotated to an open position, accomplished a by linkage connecting the lower vertical riser and the base supports.
