Watercraft Register

Watercraft Register

Trafi took over the administration of the Watercraft Register from local register offices on 1 August 2014. All registration details were transferred automatically from the local register offices to Trafi except for details on watercraft that remained unregistered in connection with the reform of local register offices, i.e. were entered in the database of inactive watercraft. Such watercraft must be reregistered.

You can check free-of-charge in Trafi's e-services whether your watercraft is registered and all details are up-to-date. If you find your watercraft in the register it means that the registration certificate issued by the local register office is still valid.

Further information on reregistration:

You can file the registration notification:

  • Through the electronic certified My e-Services service
  • By visiting an office of a contract registrar that offers watercraft registration services
  • By post: Finnish Transport Safety Agency, PO Box 320, FI-00101 Helsinki, Finland

You can also check the registration details of your boat via Trafi’s My e-Services portal (requires login).

Registration certificates now also look different.

No change in registration criteria: All boats measuring at least 5.5 metres must be registered

The Watercraft Register holds the details of all sailboats and motorboats that are at least 5.5 metres long. Any watercraft where the engine power declared by the manufacturer is at least 15 kW, i.e. more than 20 horsepower, also need to be registered.

The obligation to register a watercraft also applies to other motorised watercraft, such as water scooters, as well as watercraft owned by the State and local authorities.

Watercraft Register promotes safety and supports search and rescue services

The purpose of the Watercraft Register is to promote safety and prevent the harmful effects of watercraft use. The register helps supervisory authorities and search and rescue services, and it can also be consulted in water use planning.

The register contains information about the number and properties of boats and other watercraft in use in Finland.

The register also helps to solve watercraft and engine thefts. In addition, the data can be used to inform the public if serious faults are found in a particular type of watercraft.
