ABSTRACT:
An essentially all-plastic lightweight buoy is ideally suitable for use as a lighted discrepancy buoy. It is resistant to sinking due to damage from water traffic, floating debris or firearms. The buoy is virtually maintenance-free. It features a relatively large disc-like flotation body having a dependent free flooding ballast tube which carries mooring elements. A vented plastic battery housing is provided on the body of the buoy above the ballast tube. An elevated lantern support and leg structure is also secured to the flotation body as a rigid unit.
