Cl 114/230, 49/1 1% ⁇ ;1922335 An automatic boat docking System for guiding and docking a boat in a boat slip; including a pair of later- 51 1 t Cl B63b 21/00 d 230 231 ally spaced dock structures defininga boat slip there- 1 e 23; 5 26'3 1 l 1 between and having a pair of pivoted retaining booms l at the outer ends of the dock structures adjacent the entrance to the slip movable between a closedposition [56] References Cited transversely spanning the slip entrance and an open UNITED STATES PATENTS position.
  • the present invention relates in general to boat fending and docking aids, and more particularly to an automatic docking system employing apparatus which allows a boat to be automatically guided into proper mooring relationship in a slip and docked in the slip responsive to merely driving the boat into the'slip, without requiring work by attendants to achieve the dock- Heretofore, it has usually been required to employ one or more attending personnel, usually skilled help, to assist in guiding boats which are approaching a dock or slip into proper mooring relationship in the docking facility and to tie the boat in the slip by securing lines around cleats orother securing facilities on the dock side.
  • attending personnel on each side of the slip are employed with boat fending poles to keep the entering boat properly centered in the slip while it is advancing into docking or mooring position, to avoid possibly damaging collisions between the side of the craft and the sides of the slip.
  • attending personnel are also needed to receive the lines being tossed from the pilot or operator of the boat to secure them to stationary fastening means on the dock or slip for tying the craft in proper position.
  • An object of the present invention is the provision o a novel automatic clocking structure which maintains the craft properly centered as it advances into desired docking position within a slip and which automatically closes b ooms at the entrance end of the slip when the boat has entered into proper docking position to restrain the boat in the slip.
  • Another object of the present invention is the provision of a novel automatic docking system for boats'having structure for automatically guiding a boat moving into a slip or docking well into proper mooring relationship therein and maintaining the boat properly centered between the opposite walls of the slip or well.
  • Another object of the present invention is the provision of automatic docking structure for docking a boat in a slip or boat well, adapted to continuously position the boat in properly centered relationship in the slip or boat well and minimizing the need for conventional fender devices and other boat positioning aids.
