Passage planning by drawing on the chart

Nov 11, 2025 · Sailing Log

Most passage plans for a weekend sail need five waypoints, not fifty-page software. The planning tool should be as fast as the thought.

Tap, tap, tap, done

In Sailing Log you open the chart, tap where you'll go, and a dashed route connects your taps, around the shallows, the correct side of the buoys, because you can see both while you tap. Distance totals live as you go; with your planned speed set, ETA updates with it. Twelve miles at five knots: the math does itself.

Plans are future logbook entries

A saved plan isn't a separate artifact; it's a trip that hasn't happened yet. It gets a name from the marinas it connects, a date if you schedule it, your boat, and the crew you toggle on. When you cast off you press Start sail on the plan, and it converts into a live recording with the route still on the map.

Guidance under way

While following a plan, the recording screen and Lock Screen show course-to-steer toward the next waypoint and how far off you are, gentle arrows, not authoritative routing. The plan keeps you honest; your eyes keep you safe.

For the trip you already took but never recorded, the same drawing tool works in reverse: sketch the route, set dates and speed, and it becomes a finished logbook entry.

Sailing Log is a private-by-design logbook for iPhone & iPad: GPS tracks on nautical charts, an anchor alarm, passage plans, and share-worthy trip cards. Learn more →
