Conventional Ferry

          

Considerable power needed with several engines and jet units or propellers and rudders


Fuel consumption usually much less than the total consumption of the vehicles carried

         

Flexible route, needs only a ramp

         

Qualified skipper needed

        

Survey and maintenance needed from time to time.

    

Radar required

       

No interference with river traffic

      

         

Can operate over varying depths

       

Requires skilled steering and can be hard to dock in extreme conditions

      

Has much interest to tourists

       

Much cheaper capital cost than comparable bridging. Bridges need maintenance too!

Cable Ferry

          

Only one medium power engine required, and no rudder.  Uses a positive drive with no slippage.

       

Fuel consumption even better, about 25% of that of the conventional ferry

            

Needs a ramp and cable(s)

        

Less qualified skipper needed

            

Survey and maintenance needed including a new cable every few years, which takes one day.

           

Radar not essential

       

Very slight interference with river traffic because of the taut cable in front of the ferry when moving

      

Depths must not be too great

      

No steering required and can operate in almost any conditions

       

Has even more interest to tourists

       

Much cheaper to build and to operate than ordinary ferry


Comparison of Conventional  and Cable Ferries

Charts showing the present and shortened ferry routes.  Note that with the shorter route the depths are much less at the North end, giving the possibility of using an energy- and cost-efficient cable ferry.
