eCat A/K-Series
High Agility, Platform Scalable, Flexible Payload
Twin-screw electric cat where maximum payload capability and operation in open water is required.
Wave-piercing Hulls - scalable from 14 to 18 ft to suit application
Skid-steer type agility - ideal for waypoint loitering, pivot steering in confined environments and operation in aggressive currents
Powerful dual thrusters offer plenty of reserve power with software controllable limits to avoid overpowering smaller hulls
Wide array of user configurable payloads
Hull Type
Catamaran hulls constructed from rotomolded polyethylene for maximum durability and impact resistance.
Designed specifically for efficient operation at survey speeds (~1.5 to 2.5 m/s) with burst speeds upwards of 9 m/s.
Sensor Payload
Capable of carrying larger and heavier payloads than a Standard Jetyak
Special-missions payloads to specific requirements can be integrated by the client or ICS
