What Sensar Marine does
Sensar Marine is a privately held Norwegian-American IoT company that designs, manufactures, and sells remote boat monitoring systems. Founded in 2017 by Paal Kaperdal and headquartered in Bergen, Norway with a US commercial headquarters in Lexington, Massachusetts, the company sells a hardware-plus-subscription ecosystem centered on the Boat Monitor device — a waterproof, cellular-connected unit with an internal battery that continuously tracks vessel battery voltage, bilge pump activity, water-in-bilge depth (via the paired Bilge Sentry sensor), air and water temperature, GPS position, and G-force impact events, and delivers alerts through a mobile app and cloud platform on a required monthly or annual subscription. The system supports NMEA2000 marine-electronics integration and is extended via the Expansion Hub add-on, which received a DAME Design Awards Special Mention at METSTRADE 2025.
The company operates a hybrid go-to-market model combining direct e-commerce to individual boat owners, a dealer and distributor network across Europe and North America, and embedded OEM partnerships with boat builders — most notably Catalina Yachts (standard feature on all 2025 sailboats over 22 feet), Viknes/Skilsø, Hydrolift, Viking Boats, Brig, and North River Boats — for factory pre-installation on new vessels. Secondary customer segments include charter and fleet operators (e.g., X-Yachting Sailing Center) and, via a 2025 partnership with Norwegian insurer Gjensidige, marine insurance providers exploring usage-based risk products. The company has installed monitors in thousands of boats across at least ten countries, has approximately eleven named employees split between engineering in Norway and commercial operations in the US, has won the 2023 NMEA Technology Award, and has not disclosed external institutional venture capital beyond its June 2022 selection for the Newchip Seed-Stage Accelerator Program.
