Struts (made from a metal tube) and the gangway are hinged at either end of the rear edge of the pontoon and also at the concrete abutment blocks on the shore. The hinge action allows vertical movement for tide changes and wave conditions. Diagonal braces of a stainless steel cable are fitted between the gangway and strut for lateral support. 

Pontoons can be secured by connecting a metal strut and the gangway, to amass concrete land anchor on the shore. If the conditions are suitable, this is an economical alternative. This method is suitable for the berthing of private leisure craft in moderately calm conditions and in areas where the water is deep, or the seabed is rocky yet close to the shoreline.
