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.
Guide
Harbours, anchorages and passage plans — where to go, and what you'll find when you get there.
Log
Your time on the water, kept. Replay an outing speed-coloured, read the tacks, and download it as GPX.
Anchor
Anchorages, and a lookout that stays awake — a watch that wakes you if the boat starts to move.
Line Honors
Race control, start to finish. Sequences, marks and finish times for a club race night.
Wake soon
Trips worth showing: flotillas, life lists, sea service.
