ELECTRONIC WATCHDOG

Siren Marine’s MTC boat monitoring system lets you keep an eye on your pride and joy from just about anywhere, as long as you have Wi-Fi or a 3G cell connection. The onboard sensors—wireless or hard-wired—will alert you via an iOS or Android app to undesirable scenarios like high bilge water levels, low battery voltage, shore power status, intrusion, excessive temperature (think fire!) and boat location (think theft, or anchor dragging). Add-ons include the ability to control onboard switches and check out engine metrics from your device or computer. $599, plus subscription. Siren Marine, sirenmarine.com
