Boats left in the water, even overnight, risk water intrusion from a variety of sources. Albin Pump Marine’s new Bilge Boat-Monitor System provides real-time onboard data via smartphone app for any size powerboat. It tracks bilge-water level and battery status, and also includes a tracking alarm that activates if the boat is moved outside a defined perimeter. The unit weighs 2.2 ounces, so it can be mounted almost anywhere. The system costs $395.
