The Mariner MK II is an enhanced version of our field proven original Mariner USV.

The Mariner USV’s polyethylene construction is stable, unsinkable and near maintenance-free. It is built for use and practicality with a design that fits easily into a standard 20 ft container and simplifies transportation. The Mariner has a diesel-powered propulsion sysem
with a waterjet. Optionally, the USV can have a dieselelectric propulsion system with two electric Torqeedo thrusters and a generator in addition. This gives it a minimum of 50 hours endurance at 5 knots.

The Mariner contains a large payload room, which can be equipped with a variety of surface and subsea sensors and payloads. For example: EO and IR cameras, radars, oceanographic instruments, hydroacoustic positioning systems, echo sounders: single and multi-beam sonar systems. The subsea sensors can be mounted through a moonpool in the mid portion of the craft and users have the option to install an elevator mechanism for lowering the sensor under the hull. The USV operator uses the Vehicle Control Station (VCS) to monitor the Mariner and the data being collected from its installed payloads. The VCS features nautical charts, AIS, and radar overlay, which can be augmented with AIS and radar-based collision warnings.
