Questions

Do I need Microsoft Excel?

No. The planner works in Excel, but it also opens and works in free Google Sheets — and in LibreOffice or Numbers. You get a single file that works in all of them.

Is it metric or imperial?

Metric throughout — litres, nautical miles, knots, kilograms and Australian dollars. It is built for Australian and metric-using boaters, so there are no gallon/litre mix-ups.

How is this different from the free calculators on the site?

The free calculators are single-purpose and online-only. The planner is offline, lets you enter your boat once and reuse it everywhere, adds multi-leg trip planning and a fuel log, and bundles 21 engine presets — all in a file you keep and edit.

Will the formulas update if I change my numbers?

Yes. Every result is a live spreadsheet formula, so change any input and the burn, range, capacity and cost figures recalculate instantly.
