Saildrone, Inc. Saildrone SurveyorvsSaildrone Voyager

Choose the Saildrone Surveyor for large-scale national security or infrastructure projects requiring deep-water capabilities, such as anti-submarine warfare (ASW) or transoceanic cable route surveys. Its 13,607 kg frame and integrated diesel generator provide the power density necessary for high-resolution multibeam sonar systems that map the seabed at depths up to 7,000 meters. While the Voyager is limited by solar/wind power, the Surveyor’s hybrid system ensures continuous operation of energy-intensive sensors in remote, high-latitude environments where solar gain is insufficient. It is the primary choice for defense contractors and telecommunications firms needing heavy-duty, long-endurance maritime intelligence.

Opt for the Saildrone Voyager for persistent maritime domain awareness and environmental monitoring tasks where agility and zero-emission endurance are prioritized. At 750 kg, it is significantly more deployable than the Surveyor and achieves a higher top speed of 4 m/s, making it ideal for intercepting illegal fishing vessels or monitoring coastal borders. The solar and wind hybrid power system supports a full year of runtime without diesel refueling, reducing operational complexity for fisheries enforcement and ocean carbon research. Choose this model for high-frequency hydrographic surveys and near-shore surveillance where a smaller, purely renewable footprint is more cost-effective.
