Notice to Consumer
Significant Wave Height is measured as the average of the highest one-third (33%) of waves (measured from trough to crest) that occur in a given period. Max wave encounter will typically be double the significant wave height.
The measured roll data contained in the bulletin represents the performance of the Seakeeper system on a spcecific vessel in an estimated sea condition. It is provided as a guideline and should not be relied upon as representative of performance on this vessel in other sea conditions or on other vessels. Please contact Seakeeper for gyro sizing and roll reduction predictions for your vessel.
