Seafloor Echoboat-240™ U.S. Army Corps of Engineers, Los Angeles District

The Seafloor Systems EchoBoat-240™ is a scaled-up version of our standard workhorse EchoBoat-160™ remote-controlled and autonomous survey platform. It was designed for applications requiring the highest resolution sensor suite available, and to be more stable in rough water.

Ease of use was top of mind during development. The hinged water-tight lid quickly opens and closes, so all one has to do is power on the vessel, deploy it, and begin surveying. Live props reduce weed entanglement, and the SVP is encapsulated in the bow for protection. The wave-piercing hull was designed by our engineers to efficiently collect data and save time in the field.

With the EchoBoat-240™ platform, users can integrate robust equipment payloads to obtain professional grade results. Still two person transportable, it is ideal for launching from a trailer or cart in areas where a manned boat is not feasible. It can also be lowered via davit from a survey boat to be used as a force multiplier, working in shallower areas or alongside the main boat.
