A Vortex Theory for the Maneuvering Ship 



Because 0(oo) = o , one has:

cp(t') = 0(r') dr', 



16. Some Experimental Results 



We included in the draft of this paper, and we reproduce here four sheets 

 (Nos. I to IV) which show the behaviour of some apparent coefficients related 

 to z and % for a model of about 3 m in length, fitted with planes
