Notes 



1. Each code figure except "zero" covers a range of )4 meter; e. g., code figure 

 1 = # meter to % meter, code figure 2 = % meter to 1)4 meters. 



2. If the wave height is exactly between the heights corresponding to 2 code 

 figures, the lower code figure is reported. 



3. For wave heights greater than 31 feet (9% meters), the code figure for 30)4 

 feet (9)4 meters) is reported followed by the word "WAVES" and the actual height 

 of the waves in feet or meters; e. g., WAVES 37."
