Sensar Marine

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.

Core offering

Sensar Marine designs, manufactures, and sells IoT-based remote boat monitoring hardware (Boat Monitor device, Bilge Sentry water sensor, Expansion Hub) that continuously tracks boat battery voltage, bilge pump activity, bilge water depth, temperature, GPS position, and impact/movement. Data is transmitted over cellular networks to the company's private cloud platform and delivered to boat owners via iOS/Android mobile applications and a web portal, with SMS and email alerts. The hardware is paired with a recurring monthly or annual subscription service enabling data connectivity, alerts, cloud storage, and software updates.

Product overview

Sensar Marine offers a unified boat monitoring ecosystem centered on the Boat Monitor device, which tracks critical boat systems (battery, bilge, water level, temperature, GPS, and movement/shock). The core product is the Boat Monitor + Bilge Sentry bundle, which pairs the main monitoring unit with a dedicated bilge water-level and temperature sensor. Optional add-ons include the Expansion Hub for extended sensor connectivity. All data flows from the device to Sensar Marine's private cloud and is accessible via the Sensar Marine mobile app. A required cellular subscription covers data communication, SMS/email alerts, and web portal access.
