towing experiments with this model supported calculations in a very satisfac- 

 tory manner . •'•'*® The shape of the curve denoted as "small swanneck" is closely 

 related to a bulb form. However, the "small swanneck" remained superior to 

 normal lines fitted with a bulb; it is definitely superior to Taylor's Stand- 

 ard form for ^ = 0.68. We dwell at some length on this range of speed since 

 it acquires increased interest in connection with fast cargo ships.
