The Floating Guide Post features the ability to adjust the overall height from 48 to 60 inches. The user can choose to notch the post to a specific height or set on floatable mode and allow the waterline to naturally and automatically adjust the overall height as it enters/exits the water. This allows the post to always remain above the water line and function regardless of the boat ramp inclination. The metal tube is made from heavy duty 14 gauge steel. Pre-galvanized, and powder coated for a durable finish. It features a 30 degree slant through the bottom 18 inches to allow for varying hull shapes.
