Installing the Gobious C tanks sensors || Sailing GOAT ep 91

This week aboard GOAT 2.0, our Lagoon 400, we officially start the next phase of upgrades by improving one of the most critical (and often overlooked) systems onboard: tank monitoring. We installed Gobius C tank sensors, bringing accurate, reliable tank level information back to the boat without drilling holes or dealing with unreliable floats. But it wasn’t all wiring and configuration—because boat life is also about balance. So we took a break, jumped on our Harley-Davidsons, and rode along the southern coast of Spain, discovering the town of Adra… and unexpectedly finding tequeños, which immediately made the trip worth it. ⚙️ GOBIUS C TANK SENSOR – TECHNICAL OVERVIEW The Gobius C is a non-invasive ultrasonic tank level sensor, designed specifically for marine environments where reliability and simplicity matter. Instead of installing probes or floats inside the tank, the Gobius C is mounted externally on the outside of the tank and uses ultrasonic technology to measure the liquid level through the tank wall. Key Features & Specs: Non-invasive installation – no drilling, no contact with liquids Ultrasonic sensing through plastic or fiberglass tanks Compatible with fresh water, grey water, and black water tanks NMEA 2000 compatible, integrating directly into modern marine networks Outputs real-time tank level data to chartplotters, MFDs, and monitoring systems Extremely reliable in sloshing conditions and under sail Zero maintenance, no moving parts On GOAT 2.0, the Gobius C sensors feed directly into our NMEA 2000 backbone, allowing us to see tank levels on our navigation displays and inside our Raspberry Pi / Signal K system. This is a massive upgrade over traditional float sensors, which are notorious for sticking, failing, or giving false readings. For a cruising catamaran, knowing exactly how much water you have left is not a luxury—it’s safety and autonomy. 🏍️ LIFE BEYOND THE BOAT After days of boat projects, we needed a change of pace. So we fired up the Harleys and rode along the stunning Andalusian coastline, ending up in Adra, a small coastal town with deep maritime roots and a relaxed, authentic vibe. And then came the surprise: tequeños. Crispy, cheesy, perfect fuel after a long ride. Sometimes the best discoveries happen when you’re not looking for them.
