<p>Deck cargo is often lost at sea, either by breaking free from its stowage lines and falling overboard or as the result of some accident such as a collision, and can cause serious problems, not only because of the expense involved but also because it may result in damage both to the environment (it may be, or contain, toxic materials) and to subsequently passing shipping (it can be a navigation hazard, or it may result, say, in torn or damaged fishing nets). The invention proposes a simple and inexpensive way of locating lost cargoes, namely a marker buoy (22) that is detachably secured to a support (14) mounted on and carried by the cargo (10), and is releasable therefrom (when the cargo is lost overboard) to float to and on the surface while remaining tethered (by line 23) so as to mark the position of the cargo.</p> |
