Product Add-ons

The Mono-Port structure can remain all winter on seasonal docks in tilt-up storage position, or completely disassembled with the single ratchet tool for indoor storage. Our patented mesh end doors allow storms to blow through, and the patent-pending “Flo-Vent” seams allow wind to penetrate and escape, without damaging the structure.


After removing the fabric for the season, the Mono-Port XL can be uncoupled into two halves, allowing the pier to be stored on shore without removal of the structure.

We had a major storm several days after they installed our new Canopy. I watched out my window as it performed exactly as promised; the vent flaps puffed open as air was relieved, and the canopy never moved.
Several weeks later, we had a storm and flood, and our mooring lines broke and we feared our boat had blown away. When we came to the pier, the boat was safely nestled inside the Mono-Port, dry and damage free.
