Klamp

Klamp is the digital version of the green/red berth sign used in Scandinavian harbours: when the owner sails out, the sign flips to green and the berth is open to visitors. Flip your klamp when you head out — and visiting sailors can see on the map that your berth is available, and when you're expected back. LIVE AVAILABILITY • Find available berths on the map — live, reported by the sailors themselves • Green dot: the berth is available. Red: it's taken • Moor on trust and confirm your arrival at the berth • Watch your harbour and get notified when a berth becomes available THE HARBOUR GUIDE • Over 10,000 harbours in 23 countries — with more on the way • Facilities, phone, VHF and website — all in one place • Seamarks and depths on the chart — shown from the start YOUR BERTH, YOUR SIGN • Register your berth with a precise position and get a print-ready QR sign for your mooring post • The sign works from day one — guests can scan it with no app and no account • Flip the klamp FREE when you sail out — and HOME when you return • Get notified when a guest moors — and when they sail on • Message each other in the app: owner and guest share a thread about the stay ALWAYS FREE TO SHARE • Sharing your berth never costs anything — and never will • Say thanks with a klamp — the harbour's own high five • Plan your route with waypoints, free of charge • Anchor watch: an alarm on your phone if your anchor drags YOUR PRIVACY • Positions are only shared when you say yes • Routes and logbook never leave your phone • No tracking, no cookie banner — and EU hosting KLAMP+ (optional subscription) • Reserve a berth ahead of time — on trust, never as a guarantee • Watch all your harbours at once • Wind and weather on map and chart • Logbook: save your trips with track, speed and distance — on your phone only • Follow your planned routes live, leg by leg • Ahoy: show your position to just the friends you choose Klamp does not replace official nautical charts, and availability is based on sailors' own check-ins — Klamp cannot guarantee that a berth is available.
