The Sur-Moor taper shape design places more floatation area at the waterline creating a higher visibility mooring. The hard-skin polyethylene shell is UV protected to resist the weathering effects of sunlight and is foam filled to positively displace water. Shell has a sandblasted finish which allows the buoy to be easily painted for identifying. Available in the Tube-Through-The-Center design with blue reflective striping. Hardware not included. 2-1/2" Tube Dia. and 24" Buoy Dia. with 65 lbs buoyancy.
