Basic Specifications
The main control box is located in the helm console and handles all of higher level commands for steering and bucket control. There is also a jet controller located near the waterjets which handles all of the lower level commands for steering and bucket control. There is no need for a large bundle of cables running down the length of the vessel to connect the waterjets to the helm control panel. The main control box located in the helm console is simply connected to the jet controller located near the jets via an Ethernet Cat 5 cable, making the installation or refit for boat builders much easier than running streams of cables.
iNAV Control Stages
The iNAV-iN1 is a basic control system including the necessary equipment for control of the hydraulic waterjets, plus the critical hydraulic components for proportional bucket and nozzle control, ranging from one control station and single jet installation up to six control stations and multiple waterjet installation. The iNAV-iN1 control system can be upgraded at any time to the iNAV-iN2 to include joystick control, the iNAV-iN3 with a touchscreen glass helm, up to the iNAV -iN4 with dynamic positioning capability.
