Towfish – Fiberglass

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.
