## What is Klamp?

Your berth sits empty while you are out sailing. And somewhere nearby, a visiting sailor is looking for somewhere to tie up.

Klamp is the digital version of the green/red plate. Flip your klamp as you cast off — others can see the berth is free, and you come home to a harbour that is alive.

HOW IT WORKS

Flip the klamp
One tap as you sail out. Say when you are back, so the guest knows exactly how long the berth holds. If your plans change, the change lands straight away — on the chart, in the harbour and on the berth.

Find a berth
Free berths glow green on the map. No booking, no fee — you moor on trust, the way sailors always have. You have to be at the berth to take it, so first come, first served means actually coming first.

The sign ties it together
Print the QR sticker from the app and fix it to the mooring post. Anyone walking past can scan it and see at once whether the berth is free — even without Klamp.

ON THE WATER

Depth lies in soft contours beneath the boat, and when you plot a route you are told the shallowest measured point on every leg before you sail.

Drop the anchor and sleep. The anchor watch remembers where the anchor went down and wakes you with an alarm of its own if the boat drifts out of the circle.

And if you are ever unsure what a buoy is telling you, the seamarks are explained in the app's own reference book.

And if someone goes overboard, one tap saves the point from the phone's GPS and shows the course back — the coordinate is laid out to be read aloud on VHF. Klamp does not place calls: channel 16 and 112 are the way to help.

THE HARBOURS

Over 10,000 harbours in 23 countries — from Norway and Finland to Portugal and Greece — with toilets, showers, power, water, fuel and a crane, where we know of them. Many carry a description gathered automatically from the harbour's own website; it always shows its source and date, so you can see where it came from.

Save your favourites, keep your own notes, and let the app remember your recent searches. Your boat's dimensions are stored, so you are warned when a berth is too small — but we never hide it from you. Karma and klamps are the sailors' own way of saying thank you. And if you want the app to yourself, you can lock it with Face ID.

Klamp speaks English, Danish and Swedish.

KLAMP+

Wind drawn across the chart, so you can see what you are mooring into. Navigation with the instrument on the Lock Screen: speed, cross-track error and arrival time that keep telling the truth while the phone sits in your pocket. Watch the harbours you are heading for. Book ahead. And your own logbook with track, speed and distance.

Weather on every harbour: a ten-day forecast, a tap on the day unfolds the hours. Your logbook follows you across your devices through your own iCloud — never through us. Keep two berths? Manage both from one account.

39 DKK/month or 249 DKK/year; the price in your currency is shown in the App Store. The subscription renews automatically until cancelled in your App Store settings. Sharing your own berth is free — and always will be.

PRIVACY, TAKEN SERIOUSLY

"The berth is free until Friday" also means "the owner is away until Friday". That is why we never show who owns a berth, and your name is shared only if you say so.

When you confirm you have arrived, we work out the distance and throw the coordinate away — it is not stored. If you share your passage on Ahoy, it happens only with your explicit yes: only your latest position sits on the server, others can see it for ten minutes at most, and strangers never see anything but an anonymous dot. One tap removes it entirely.

No ads. No tracking. No advertising networks. We host in the EU, and everyone else who touches data is named openly in the privacy policy.

Klamp cannot promise you a free berth — only show you where one is right now.

Made by sailors, for sailors. Fair winds.

## Version history (last 3 releases)

### 1.2.1 — 2026-08-23

The weather has moved into the harbour — and your logbook now follows you to your other devices.

• Weather in the harbour: a ten-day forecast, and a tap on the day unfolds the hours. Temperature, feels-like, wind in knots with direction, pressure, UV, visibility and cloud cover — plus minute-by-minute rain where it exists. Sun and moon at the bottom. With Klamp+.
• Severe weather warnings appear at the top of the harbour, in the authority's own words and with a link to their page. Klamp does not issue warnings — we pass them on.
• Your logbook and your man overboard log follow you to your other devices through YOUR own iCloud. They never pass through our servers: we can neither read them nor hand them over. Turn it off under Settings → Across devices.
• Units, theme, language and your boat's draught now follow your account. Sign in on a new phone and everything is as you left it.
• You can finally create more than one berth. If you keep two, they now sit side by side.
• Man overboard got more precise: the point now comes from a fresh GPS fix rather than the map's last one. The map in the log can be zoomed, and the point can be opened in Maps or shared — the coordinate is laid out to be read aloud on VHF.
• And the whole app has become a nicer place to be: faster tab switches, softer motion, a new opening moment, and a chart that responds instantly.

The button still does not call for help. Channel 16 and 112 remain the way to reach it.

Fair winds!

### 1.2 — 2026-08-15

The ships have arrived on the chart. 
• See the big traffic around you — the ferry, the freighter in the approach. Course, speed and the vessel's real size, without paying for it
• With Klamp+ you also see who and where to: name, destination, estimated arrival and draught
• Commercial vessels only. Leisure boats are never shown — not even your friends'
• This is orientation, not navigation. Data via AISHub
The QR sign has become a real flip plate
• Green and red both stand on the sign — with word and figure, so colour never carries the message alone
• Print it in Danish, Swedish or English, whichever language you use the app in
• If a guest scans your sign, they can now read the note you left for them
And a handful of smaller things:
• The klamps on your profile can be folded away, so the rest of the page is within reach
• You can report a message if someone writes something that does not belong
• Questions and answers are easier to read
• If you bought Klamp+ without getting access, the app now says honestly why — instead of staying silent

### 1.1.2 — 2026-08-10
