Unit: Wave Height (Significant, meter), Wave Period (sec), Wind Speed (m/sec or km/hr or knots), Current Speed (m/sec or km/hr or knots).
Note
Experimental product; caution is advisable upon utilization. Sea state is liable to constant change, and maximum wave height could reach twice the significant wave height.
Forecast wind degree greater than or equal to 6 or wave height greater than or equal to 3 meters; safety precaution is advisable.
Forecast wind degree greater than or equal to 8 or wave height greater than or equal to 6 meters; safety precaution is strongly advisable.
