Enter the route miles, how fast you paddle on flat water, whether the current is with you or against you, and whether the wind is a headwind, a tailwind, or a crosswind. Breaks are minutes you will actually stop. Launch and sunset are clock times you type.
An out-and-back splits the miles in half and reverses the current and the head or tail wind on the way home. A point-to-point keeps one heading. The sheet also asks who is going, where you launch, and who to call.
The total time is free. $5 unlocks the legs, the turnaround, and the float plan.
