Towfish (2)
Okeanus brand faired fiberglass tow bodies are highly stable, neutrally buoyant, hydrodynamically clean, high-speed systems based on extensive practical experience with the development of stable two-body swath bathymetric seafloor mapping sonar systems and are built to the specific requirements of our client’s needs.
SOSI has engineered and built many different open- frame towed body (towfish) systems. While the majority of SOSI tow bodies are towed through the water column, many of our systems are designed for landing on and towing across the seafloor. These sled designs, typically used for cable burial, ocean mining, environmental impact assessment and video/ photographic survey, are not only stable when towed through the water column, but maintain their orientation when landed on the seafloor. Our experienced engineers often integrate instrumentation such as, altitude sensors, environmental sensors, camera / video systems, lighting equipment, telemetry systems, pumps, motor starters and control systems into our tow bodies.
Features
- Aluminum construction

- Stainless fasteners
- Tow bridle attachment
Options
- Galvanized steel or stainless steel construction
- Removable flotation modules
- Seafloor landing skids/runners

Towfish
SOSI’s knowledge of underwater technology has enabled our staff to produce a portfolio of highly efficient fiberglass tow body vehicles. The majority of these underwater vehicles are neutrally buoyant towed bodies with fiberglass monocoque frames typically used for sonar applications. Systems may be constructed with internal aluminum framing, fiberglass exterior, and acoustically transparent polyethylene fairings over the transducers and arrays. The SOSI 12kHz Towfish (pictured) is an example of our fiberglass, neutrally buoyant towed bodies, which was specifically designed for low frequency swath bathymetric seafloor mapping systems.
Features
- Fiberglass monocoque design
- Removable flotation modules
- Hydrodynamically stable design
- Easily accessible arrays & housing
- Acoustically transparent array covers
- Integral lift beam
- Slight positive buoyancy
- Stainless fasteners
- Trim & ballast adjustment
- Single point tow attachment
Options
- Internal aluminum frame
- Tail drogue assembly with flasher & Iridium beacon
- Acoustic/pressure actuated release
