Harbour
Book a guest berth that fits your boat, compare fuel prices, and charter, rent or sell boats in one app.
Harbour brings everything sailors need into one app. Find a guest berth that fits your boat and book it with the full price shown, compare fuel prices across harbours, and charter, rent, buy or sell boats. Harbour masters run their berths, arrivals and fuel prices from the same app.

The problem
- Sailors arrive at a harbour without knowing if a berth that fits their boat is free.
- Fuel prices differ a lot between harbours and are hard to compare.
- Many small harbours still take guest berth payment at a machine or in an envelope.
The product
For sailors: every harbour shows free berths tonight, the largest boat it takes, depth and prices. Booking checks length, beam and draft and shows only berths the boat fits, with the full price including shore power. For harbour masters: arrivals and departures, check-in with one tap, occupancy and instant fuel price updates. A boat market covers charter, rental and sale.
- The sailor saves their boat's length, beam and draft once.
- They browse harbours, fuel prices and free berths.
- Booking shows only berths that fit, with the full price.
- The harbour master sees the arrival and checks the boat in with one tap.
- Boat owners list boats for charter, rent or sale; buyers message in the app.
Who pays and why

Market and targets
Northern Europe has a dense network of guest harbours and a large leisure boating population that sails between them every summer. Harbour systems are fragmented and many are run by small municipal or club harbours that cannot build their own apps.
Targets are planning assumptions.
