Determine your boat's power usage by completing the chart below.
Use the estimates below or calculate usage by multiplying the current used by each device times the expected hours of usage per day.

If you have an amp meter in your power distribution panel, record the amps used by each piece of equipment. Multiply it by the number of hours used per day. Total the equipment Amp Hours to obtain the daily Amp Hours used. Add 20% to obtain the Amp Hours that must be put back in the batteries per day to keep even.
Calculate the usage both at anchor and underway, and call or email us with the results.
