C-Enduro is a long endurance autonomous surface vehicle used to safely and cost effectively collect data at sea. Built to operate in all marine environments, C-Enduro uses energy harvesting technology combined with an efficient self-righting hull.

C-Enduro's unprecedented payload capacity and power enables the use of a combination of payloads during any one mission. Use of the C-Enduro can dramatically reduce the cost of data collection by removing the need for traditional survey vessels.

Use of mission planning and waypoint setting can often result in a more accurate dataset.

C-Worker 5 is the ideal platform to support hydrographic survey work. Designed as a force multiplier to enable increased survey coverage and minimised weather risk through reduced survey duration. C-Worker 5 is reliable through simplicity, utilising an off the shelf direct drive marine diesel propulsion system operated by L3 ASV's proven ASView control ... Moresystem. This system integrates quickly and easily with a wide variety of acquisition systems, enabling line plans to be uploaded to the system for accurate data collection.

C-Worker 5 is designed for up to 7 days endurance at survey speeds of up to 7 knots, minimising launch and recovery operations and increasing survey efficiency.
C-Cat 3 has been developed to complement the existing ocean-going L3 ASV vehicles for survey and support tasks where a smaller vehicle is better suited to missions. The design incorporates a large payload bay to enable flexibility of payloads used. ... More

The shallow draft and small size of the vehicle enables deployment in littoral areas and its modular construction facilitates the fitting of a range of scientific above and below water payloads.

C-Cat-3 includes the core functionality proven in all L3 ASV vehicles and systems and thus is a reliable and robust platform for path planning, autonomy research and scientific experimentation with payloads.
