Bay Area Boatbuilder Launches 72-ft Saildrone

Bay Area boatbuilder Saildrone has launched a new vessel, the Saildrone Surveyor — a 72-ft uncrewed surface vehicle (USV) equipped for high-resolution mapping of the ocean seafloor. And according to the press release, it is the world’s most advanced uncrewed surface vehicle.

The Surveyor carries a sophisticated array of acoustic instruments for both shallow- and deep-water ocean mapping; the Kongsberg EM 304 multibeam echo sounder is capable of mapping the seafloor down to 7,000 meters below the surface. The Surveyor also carries two state-of-the-art acoustic Doppler current profilers (ADCPs), the Teledyne Pinnacle 45 kHz ADCP and the Simrad EC150-3C ADCP, to measure ocean currents and understand what is in the water column. The Surveyor is also equipped with the Simrad EK80 echo sounder for fish stock assessments.

The Saildrone Surveyor was launched from Saildrone headquarters in Alameda, CA, this month. It coincides with the start of the United Nations Decade of Ocean Science for Sustainable Development and presents a paradigm shift in enhanced seabed mapping. Ocean mapping is currently done with very large and expensive crewed ships. The Saildrone Surveyor is a scaled-up version of the Saildrone Explorer, the 23-foot wind- and solar-powered saildrone, which has been proven in numerous operational missions for science, ocean mapping, and maritime security, covering more than 500,000 nautical miles from the Arctic to the Antarctic.

Like the Explorer, the Saildrone Surveyor is uncrewed and uses renewable solar energy to power its robust sensor suite. The Surveyor delivers an equivalent survey capability, but at a fraction of the cost and carbon footprint of a traditional survey ship and without putting human health and safety at risk.

“The launch of the Surveyor is a huge step up, not just for Saildrone’s data services but for the capabilities of uncrewed systems in our oceans,” said Richard Jenkins, founder and CEO of Saildrone. “For the first time, a scalable solution now exists to map our planet within our lifetime, at an affordable cost.”

With the Surveyor, Saildrone aims to accelerate many of the global mapping initiatives that seek to provide better insights into Earth’s processes: Seabed 2030 is a UN-backed joint initiative between GEBCO (the General Bathymetric Chart of the Oceans) and the Nippon Foundation to produce a definitive map of the world’s oceans by 2030, and the 2019 White House Memorandum on Ocean Mapping calls for a national strategy for mapping, exploring, and characterizing the US Exclusive Economic Zone.

“We are excited to see the launch of the Saildrone Surveyor,” said Alan Leonardi, director of the NOAA Office of Ocean Exploration and Research. “NOAA is supporting the development and testing of this new uncrewed system because we are confident it will expand the capability of our existing fleet of ships to help us accelerate in a cost-effective way our mission to map, characterize and explore our nation’s deep ocean territory, monitor valuable fisheries and other marine resources, and provide information to unleash the potential of our nation’s Blue Economy.”

Less than 20% of Earth’s oceans have been mapped using modern, high-resolution technology—we know more about the topography of the Moon and Mars than we do about our own planet. And yet, knowing the shape of the seabed is critical to understanding ocean circulation patterns, which affect climate and weather prediction, tides, wave action and tsunami wave propagation, sediment transport, underwater geohazards, and resource exploration.

Saildrone’s fleet of USVs has logged more than 10,000 days at sea in some of the most extreme weather conditions on the planet. In 2020, Saildrone completed its first Arctic mapping mission on behalf of NOAA’s National Ocean Service, and in 2019, Saildrone completed the first autonomous circumnavigation of Antarctica, collecting critical carbon data related to climate science.

    No mention is made of defensive measures built into its command system. How does it deal with other vessels? Staying away from container ships or aircraft carriers could be easily managed, but what about 35′ sailboats of cruisers, on auto-pilot?

    Love to see product from the vessel.

    These are great minds doing this. I wish the minds of Alexander Von Humboldt and Darwin could see this.

    Great, more floating debris in the ocean all in the name of “the environment.” LOL you can’t make this up, only in Bay Area.

Sailing a Sharpie
A few weeks back, we received word from a local sailor that an odd-looking sailboat had mysteriously appeared in Richmond. We hot-footed it over there, but by the time we arrived the boat had just as mysteriously disappeared.
The Freedom of Sailing
Freedom and escape from the chaos ashore are two of the most alluring reasons to sail on the Bay. If you escaped this weekend, send us some pics!
