All pleasure boats arriving from or departing to a third country (a non-Schengen country) are legally obliged to comply with the reporting formalities for border control. Entry from a non-Schengen country must be made at a port designated as a border crossing point. The Federal Police are responsible for and entrusted with the implementation of border control. More specifically, one of the tasks of the Maritime and River Police (SPN) is to supervise the cross-border traffic at the maritime external borders.
A report form for pleasure boating, can be completed and submitted to the SPN online. Full details can be found at: https://www.police.be/bordercontrol/en/pleasure-craft-declaration.

Belgium requires that vessels under a foreign flag have documents to prove the vessel's nationality as required by the regulations of the country in question. UK registration may therefore not be strictly necessary for boats arriving by road, however local rules may mean that a vessel (especially a RIB or PWC) cannot be launched if it is not registered and without a registration document the owner has no way of proving that the vessel is a British ship.
Signatory to the Regional Arrangement Concerning the Radiotelephone Service on Inland Waterways (RAINWAT). Where a VHF is required or is to be used on the inland waterways of RAINWAT signatory countries, the set must be ATIS enabled and vessels must comply with the requirements of RAINWAT.

In the Walloon region a Permis de Circulation may be required.
