摘要
Retractable tow line guide pins (1 and 2) at the stern of a tugboat or supply boat are made to be elevated from/retracted into the deck (3) of the vessel and are also pivotable, such that over a portion of the raising or lowering movement they are pivoted 90 DEG , whereby fixed locking members (4,5) mounted thereon and the pins themselves pivot from an inoperative position into a position in which the opening between the pins (1 and 2) is closed at the top, thereby preventing a tow line disposed in the opening between the pins from being released therefrom.
