Womens Bay to Dog Bay, and the virtually unlimited fetch across the Gulf of 

 Alaska. The depths along the Womens Bay fetch vary from a few feet to over 

 50 ft. Shallow water forecasting curves (Vincent and Lockhart 1983) for an 

 assumed constant 35-ft depth and 7-mile fetch were used to translate veloc- 

 ities and durations at selected return periods from Figures C1-C5 to equiva- 

 lent significant wave heights and peak periods for the Womens Bay fetch, as 

 presented in Table 19. The fetch limitation makes the higher velocities of 

 1-hr duration the extreme condition in terms of wave height.
