Boat Electronics

It depends on the boat and load plan. A dedicated house circuit can protect starting reserve, but it must be designed and charged correctly. Use the battery runtime calculator to estimate demand.

Use components and installation practices suitable for the marine environment, with correct conductor size, circuit protection and corrosion resistance.

Carry the navigation information appropriate for the trip, keep charts current and plan for loss of power or equipment. NOAA provides official electronic navigational charts for U.S. waters.

A VHF radio provides marine distress and working channels where coverage is available, while a phone can remain useful as a backup. Review the FCC ship radio guidance for U.S. licensing rules.

Match sonar type, transducer, mapping, display size, mounting space and power needs to the water and fishing method. Start with how to choose a fish finder.

Check current conditions, marine warnings, wind, waves, visibility and tides or currents relevant to the route. NOAA’s recreational boating resources connect boaters to official forecasts, charts and tide predictions.
