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.
