Auto-Oscillations of Anchored Vessels 



shaded region (Figure 10) covering the centre of sail area in order 

 to eliminate yawing of the anchored ship. This region is likely to be 

 equal for ships which do not differ much in respect of the deck-house 

 architecture. It is expected that such an anchor gear, if properly 

 designed, will create favourable conditions for the operation of the 

 above-mentioned ships.
