KlampKlamp is the digital version of the green/red plate. Flip your klamp when you cast off — a visiting sailor can see the berth is free, and you come home to a harbour that's alive.
One tap as you cast off. Say when you're back — so the guest knows exactly how long the berth holds.
Free berths glow green on the map. No booking, no fee — you moor on trust, the way sailors always have.
A QR code on the pile shows the status to anyone walking past. Scan it, and you see straight away whether the berth is free.
From the North Cape to Crete. Facilities, phone number and VHF channel for every harbour — from OpenStreetMap, kept current.
Every berth gets its own QR code and a print-ready A6 sign. Anyone walking past can scan it and see the status — no app needed.
Fuel, water, power, showers, toilets, a shop. Find the harbour that has what you need tonight.
Star the harbours you visit and write your own notes. “Good shelter in a westerly, the baker shuts at two.” Only you can see them.
Sea marks and EMODnet depth data over the map. Bearing and distance to the harbour, with an honest warning: it does not replace a real chart.
Wind arrows and strength drawn across the map and the chart, from Apple Weather. So you know what you are sailing into.
Cross-track error, speed over ground and a live ETA while you sail. Your position never leaves the phone.
Get told the second a berth opens up in the harbour you are heading for.
Marking your own berth free never costs anything, and never will. Klamp+ is for those who want more — watch a harbour, see who's coming, plan further ahead.
