boating.systems

Digital tools for life on the water.

A small family of apps for people who spend time on boats — built by a sailor on Long Island Sound, and free. No ads, no subscription, no account required. Sign in once and your boat, your places and your outings are the same everywhere.

The apps

Chart ↗

The underway map. NOAA charts coloured against your boat's draft, with tides, currents and your track behind you.

Log ↗

The logbook that fills itself. Outings arrive from Chart, decades of old tracks import from any app, and the days count toward a captain's licence.

Bring in your history · Sea service · From Navionics

In beta

Free to use and working, but still changing week to week.

Line Honors ↗

Race control, start to finish. Sequences, marks and finish times for a club race night.

Paddle ↗

For canoes and kayaks. Your paddling club's trips, launches and river routes, and the people you paddle with.

How this works

Free, and staying free. No ads, no subscription, nothing held back behind a paywall.
No account needed. Every app works signed out. Signing in is what lets your boat and your outings follow you between apps and devices.
Your records are yours. Outings download as GPX and open in any plotter. Nothing you record becomes visible to anyone else unless you choose to share it.
Built on public data. NOAA charts, NOAA tide and current predictions, National Weather Service forecasts, OpenStreetMap and OpenSeaMap.
