This image depicts the navigation, communications and steering control functional and physical schematic. Included are the cable lengths of the NMEA2000 backbone network (grey block) and key physical interfaces where cables penetrate the deck. NOTE: this diagram excludes depiction of existing systems and those not requiring new network cabling.

A full suite of B&G Instrumentation including 4G broaband twin radars, Forwardscan Sonar and multiple redundant GPS, WAAS and inertial sensors provided global and 9 axes local orientation. The autopilot consumed these sensor feeds.

VHF radios were located at the helm, via a remote handset from the ICOM IC M502 at the interior chart table, and in the cockpit, where the original ICOM M506, was located at the forward of the cockpit. Both VHF Radios were provided with seperate and redundant GPS feeds to support the Digital Selective Calling (DSC), emergency location distress signalling. Additionally at the interior chart table, the Marine SSB and Ham HF radios were located. Both HF radios had seperate, and redundant, Antenna tuners that each fed a seperate aft stay (standing mast rigging). The marine SSB was equipped with a Pactor Modem for email and weather grib access. An Iridium Go and marine external antenna was also fitted at the chart table and transom arch respectively.

Yacht Instrumentation Schematic

The primary human machine interface for the navigation and steering controls was at the cockpit helm. This was a custom design and build in composite based around a 12inch B&G touchscreen. The image below is the ProEngineer 3D CAD render that was used to design the helm and validate space claim of the helm. This system proved its worth during an open ocean transit down the US West Coast from Seattle Washington to Ventura California. In steep 20’ confused seas of the Oregon coast, dodging large fishing fleets, entering the very tight Neah Bay in full fog and transitting the 5Nm Grays Harbor bar, this system was faultless.
