This 30' x 30" Wave style gangway was delivered to the Suwannee River in Branford, Florida.
A flotation drum is attached to the off shore end that is hinged to the float.
This drum supports the weight of the gangway so extra flotation didn’t have to be added to the existing float.
The rollers that traditionally would sit on the float are, in this application, on shore.
This allows the custom to move the float in and out with the water level. They simply tie it off to trees to hold it in place.
