发明名称 Catamaran with a steerable centerboard apparatus and an improved deck joint
摘要 A catamaran with a steerable centerboard apparatus includes a housing rotatably mounted on the deck of the catamaran. A centerboard is pivotally mounted to the housing to permit movement between an upper and lower position. A tiller, integral with the housing, extends over the upper surface of the deck and includes an elastic band or rope attached to its end and a hook located on the deck. This inexpensive device keeps the tiller self-centered when not in use. When the user wishes to maneuver the catamaran, he simply turns the tiller in the proper direction with his hand or foot. The improved deck joint comprises a tab extending from deck which fits and mates with a recess located on the hull. The tab is formed to fit snuggly within the recess so that lateral movement is eliminated. Also, a projection located on the lower surface of the tab is received within a cavity extending in the surface of the hull recess. A pair of straps including a seatbelt type buckle are located on each side of the recess. One strap extends into a slot located on the deck and is buckled to the other strap to properly secure the deck and hull together.
