End the Guesswork: The Daily Current Draw Calculator

You've done the hard part by calculating your daily power consumption. But are you still left with questions? Are you worried you've missed a key appliance? Are you tired of that feeling of uncertainty as the sun sets and your battery monitor ticks down?

As a cruising sailor, I know the peace of mind that comes from a well-managed electrical system. This isn't just about crunching numbers; it’s about having the confidence to cruise without worrying if you’ll have enough power.

The Daily Current Draw Calculator is the simple, definitive solution to this problem. It’s a pre-formatted, fully editable spreadsheet that takes all the guesswork out of the equation.

With this simple tool you will:

Gain total clarity on your daily power consumption, both at anchor and underway.

Identify the biggest power drains on your boat so you can make informed decisions.

Accurately size your battery bank and charging regime based on your actual power usage.

Protect your expensive battery bank from damaging over-discharging.

Using it couldn't be easier. Simply enter your appliance's amperage and the hours you use it, and the total amp-hours are calculated automatically.
