were not to exceed 0.76 m (2.5 ft) in a specified mooring area (area in lee of 

 detached breakwater). For Plan 47, the wave height criterion was exceeded by only 

 0.03 m (0. 1 ft) for the most severe incident storm wave conditions. Plan 47 was 

 recommended for construction based on wave protection, navigation, and costs. 

 Typical wave patterns for Plan 47 are shown in Figure 8. 



Wave-induced current patterns and magnitudes were determined at selected 

 locations in the model by timing the progress of a dye tracer relative to known 

 distances on the model surface. Test results for Plan 47 indicated that currents will 

 move southerly along the shoreline north of the harbor. Some will enter the harbor 

 between the opening at the shoreward end of the detached breakwater and the 

 shoreline. These currents will move in a clockwise direction in the harbor and exit
