Saildrone ‘SD 1021’, the first autonomous vessel crossing the Atlantic Ocean in both directions, has completed the voyage of 3,402 nM in a record 68 days.
These unmanned surface vessels (USVs), powered entirely by wind & solar energy, can perform in the harshest ocean conditions whilst collecting data from both above and below the sea’s surface - including air & surface temperature, wind speed & direction, wave height & period, atmospheric pressure, radiation, dissolved oxygen, salinity and acidity levels. ‘SD 1021’ also has an Acoustic Doppler Current Profiler (ADCP) for both current strength & direction.
PS. With Argofloats and Saildrones as ‘Satellites of the Sea’, it’s no wonder foiling craft travelling at 40kts through the water risk catastrophic collision with ‘unknown objects’!!
