SeaDragon is the second Uncrewed Surface Vehicle (USV) of the SeaClear2.0 robotic solution. SeaDragon is used to deposit the waste collected during the collection phase. To do this, SeaDragon docks stern-to-stern with SeaCAT and maintains its position until the collected waste has been deposited in its litter bay. SeaDragon then sails back to the coast to unload the collected waste.

key features
- High maneuverability:
- SeaDragon is equipped with azimuth thrusters, allowing operation even in a sway (lateral) direction
- with a draft of only 0.3m in its basic configuration, the resistance from water is minimal, hence allow sharp maneuvers that are crucial in confined environments
- Stability:
- As the USV is a catamaran, greater stability is guaranteed in harsher environmental conditions (swell, wind, currents)
- Situational awareness:
- In addition to the high-precision navigation sensors, SeaDragon is equipped with a comprehensive perception module that is able to detect and track vessel traffic and utilise it for safer navigation
- Communication range:
- SeaDragon can be commanded up to 50km distance from shore, in applications where Beyond-Line of Sight (BLOS) is required
- For short-range application (up to 1km), SeaDragon can be used as well with a high-bandwidth WiFi antenna
