The TDL 89 informational buoy is a cost effective and stable buoy to direct boating traffic and mark hazards. IB 89 has a recessed decal band for a variety of available markings, and an embedded nut pattern in the top section to accommodate an optional solar light. This buoy utilizes the same materials and manufacturing technologies as offshore navigation buoys and has a white shell for high visibility. The broad base of the TDL 89 makes it very stable and extremely buoyant for high visibility. It has an option for an internal radar reflector.
