I think it would make for quite an interesting and unique training experience in the NAUTIS Home to have a boat with twin water jet of Hamilton system - with a common directional steering for both jets, and with the reverse bucket position control and throttle control separated from each other, for each of the water jets. With the Hamilton directional control system and multiple waterjets it is so easy to move the vessel directly sideways very efficiently in situations like docking without any additional stuff like thrusters. It is more difficult with the Aetos'es regular waterjets, because with directional control out of neutral, the sideway vector of thrust from waterjet with bucket up is opposite to the second waterjet with bucket down (in reverse).
Hamilton's is a common system and that would be great to have a boat in NAUTIS with such system to train with, as opposite to other waterjets that steer like a regular rudder. Or... maybe we could just get a second version of Aetos - equipped optionally with twin Hamilton waterjets? With separate reversing bucket and throttle controls for each waterjet and a common directional steering. Alternatively - how a about a USCG RB-M (Response Boat - Medium) instead of Aetos? That would be even much more fun...
Here comes a nice demo how to maneuver using Hamilton water jet system, including twin jet, but nothing more:
