The present invention provides an obstruction (10) for mounting along a perimeter of a vessel or marine installation, wherein the vessel or marine installation comprises a deck (51) having a perimeter railing (20) and an upstanding plate (53) along an edge of the deck. The obstruction has an elongate body comprising a longitudinal groove (12) for receiving a lowermost course of rails (203) of the perimeter railing, and a tongue (14) for overhanging the plate (53) on an outboard or seaward side thereof. The tongue comprises a rear surface (142) intended to face in an inboard direction when the obstruction (10) is mounted along the perimeter of the vessel or marine installation. A separation, s, between the rear surface (142) of the tongue and a centreline (X-X') of the longitudinal groove (12) is between 30 and 300 mm, and the centreline (X-X') of the longitudinal groove (12) and the separation, s, together define a plane which subtends an angle, ¸, of between 90 and 135 degrees to the rear surface of the tongue. With such an obstruction, the upstanding plate (53) can be protected, so that the ability of an unauthorized potential boarder to attach a hook to the plate or to gain a handhold on the top edge of the plate are severely impeded. The invention also provides a perimeter protection system (100) comprising a plurality of such obstructions (10a, 10b), a vessel or marine installation comprising a plurality of such obstructions, and a method of protecting a perimeter of a vessel or marine installation using a plurality of such obstructions.
