1 BACKGROUND
Seafloor Systems is a small California-based business specializing in providing turnkey Hydrographic Survey System solutions, both on manned vessels (small, large, new builds) and on our own Unmanned Surface Vessels (USV's). We have over 20 years experience with Multibeam sonar equipment; for two decades, we have grown and evolved with this emerging cutting-edge hydrographic technology.
Today, we choose from the the best systems, and most trusted proven ancillary components, to configure turnkey solutions scaled to meet individual performance requirements and budget. We have long-esablished official sales and support agreements with some of the best innovators in the Multibeam and hydrographic industry. As a result, all our solutions are proven, trusted, and well-supported.
Seafloor Systems USV's Hydrographic Survey Drones
Seafloor Systems has also been building Unmanned Surface Vessels for 10 years.
We have been expanding and evolving our fleet of USV options to accommodate complex multibeam and similar payloads; adapting them for the needs of hydrographers for different survey applications, scenarios, and environments.
Today, we offer the HyDroneTM, EchoBoatTM, and HydroCatTM line of Unmanned Surface Vessels. All are remote controlled, and also operate autonomously with our AutoNavTM option. Our AutoNav is integrated with the standard navigation and data collection software packages, including HYPACK, QPS, PDS2000, and Eiva. And all our USV's are designed to be easy to operate, low cost to maintain, and field-serviceable.

3 TRIDRONE
The TriDroneTM USV is a super-compact, portable platform for conducting hydrographic surveys in confined & remote bodies of water. With remotely controlled capabilities, a durable assembly, and a hull-integrated single beam echosounder, this USV brings automation and efficiency to any work site. The USV gains stability from its triple pontoon design and folds into thirds for oneperson transport. Its maneuverable servo thruster steers the USV into previously unreachable zones with heightened precision and repeatability. Safely conduct hydrographic surveys from the shore and increase productivity in the field with the TriDroneTM.

5 ECHOBOAT-160
The EchoBoat is Seafloor System's more versatile 1.8m monohull remotely operated, and autonomous survey platform. Its thru-hull mounting system allows for maximum flexibility to swap different systems and payloads in/out of the EchoBoat. It can handle slightly rougher conditions than the HyDrone.
We also offer an integrated remote-controlled profiling winch, to lower a sound velocity profiler for Multibeam surveys, or similar CTD or water quality sensors.
The EchoBoat is Seafloor Systems workhorse system; a cost-effective option used to perform Hydrographic or Hydrologic surveys with Single beam, Multibeam, Sidescan, ADCP, or multisensor payload in remote, shallow, or dangerous areas, or when routine surveys can be done more cost effectively with 1-2 person crew from shore.

6 ECHOBOAT-240
The EchoBoat-240 is a larger, scaled up version of the standard workhorse EchoBoat-160 remote controlled and autonomous survey platform. It was developed for applications requiring the highest resolution sensor suite available, and to remain more stable in conditions rougher than the standard EchoBoat-160 can handle.
With the new EchoBoat-240 platform, the user no longer has to sacrifice performance to meet payload capacity. The mounting well is designed around models including the Teledyne SeaBat T50/T20, the R2Sonic 2024, or the larger Norbit iWBMS-STX models.
Still two person transportable, it is an ideal model to launch from a trailer or cart in areas where a crewed boat is not necessary. Or launched via a davit off a survey boat, to be used as a force multiplier alongside your crewed survey vessel, working in shallower areas or alongside the main boat.

7 HYDROCAT-180
The HydroCat-180 is Seafloor Systems largest USV platform. It is a 5.5m / 18' Catamaran, with independent articulated hulls and a gimballed deck, designed specifically to handle rough conditions and manipulate over waves while keeping the payload stable. It includes a remotecontrolled retractable sonar arm, Remote controlled profiling winch, large waterproof equipment enclosure, and ample space for a customized multi-sensor payload, with both fixed mounted and towed sensors.
This model is designed for more coastal offshore use, SS2-SS3 conditions. While it is not an "offshore" platform, it is an ideal system to use as a force multiplier for survey large open areas and near shore work. Below, we have an Integrated Dual Head SeaBat T50 installed.
