Polyform U.S. S-Series Buoy 6" x 15" - White S-1 WHITE. Use as a fender or mooring buoy for small boats and jet skis. Its compact size is perfect when storage space is limited. The S Series' elongated design allows it to sit higher in the water than an ordinary round buoy. Replace the "bleach bottle" when small pot and trap fishing with a durable distinctly visible marker buoy. Water sport associations and competition enthusiasts combine the S-1 "boat guide" with the Polyform WS-1 Slalom Buoy as a complete course-marker package. For high-performance or leisure water sports choose the versatile S Series S-1 for your small fender and buoy needs.
