Is it a good day to sail?
Clew reads the tide, the wind and the rain for your berth, picks out the good days in the week, plans the trains to the boat, and keeps the logbook once you're out.

Every day, judged by the tide first
A drying berth means the tide decides whether you go at all. Plan runs a year ahead, working out each day's water in daylight from your boat's own hours either side of high water, then weighing the wind, gusts and rain for the hours you'd be out against what you're happy sailing in.
- The days you don't usually sail fade back, so yours stand out
- Past the forecast, a day still gets an opinion from the tide
- It never guesses a tide: if it hasn't got one, it says so

The whole day on one clock
Open a day and the tide, the time on the water and the journey sit on one line: leave home, aboard and ready to slip, back by the time the water goes, home again. On the day itself, it tells you when to go.
- Leave, slip, high water, back and home in one row
- “Leave in 10 min” on a planned day
- Train or car, your usual way first

Every train, both ways
Journeys are planned from your door to the station nearest the boat, changes and all. Each way of going is one row with every time it runs, the train that matters marked (the mainline one after the Tube), and the ones that would get you there too late struck through.
- Tap a time to make it your train
- Home trains leave once you're packed up

A logbook that keeps itself
A trip starts with a tap and the log fills in as you go: times, sails up, the mooring. The notes are yours and live on your phone, the Bosun's Locker keeps the jobs to buy and fix, and a boat can be shared with crew.
- Search every trip
- Backed up when you sign in, never before
Why I made it
I bought my first boat, Egret, a Leisure 23 on bilge keels, so I could sail again with my dad. Her berth dries, so whether we can go out at all comes down to the tide first, then the wind and the rain.
I wanted to plan our trips without the guesswork, and to know straight away whether a day would work when Dad and I were talking about when we could next get out.
I also wanted a logbook that didn't mean sitting aboard jotting notes, or trying to remember where we'd been when the logbook was at home. In Clew the log fills in as you sail, and it's on your phone wherever you are.
Pick your marina and your boat and it works the same for you.
