Such a registration system may be seen in Finland, where
all pleasure craft with a minimum length of 5.5 metres, or with an
engine power of at least 15 kW, including sailboats, are required
to be registered. The vessels are required to be visibly marked with
a registration number, and registration documentation containing information
regarding the owner, vessel and engine technical specifications and
serial numbers is mandatory in order for the pleasure craft to be
used. The register of information is kept by local city administrative
courts and the registration number can be traced to the appropriate
register.
