Ship certificate & approval for passenger vessels
No other document determines the value and usability of a passenger vessel as strongly as its approval. Anyone looking to buy a used passenger vessel should understand the ship certificate, the survey status and the permitted navigation zone in detail – they dictate how many passengers may be carried, where the vessel may operate and which investments will be due over the coming years.
The ship certificate: the operating licence
The ship certificate – today referred to EU-wide as the Union certificate for inland navigation vessels – is the operating licence of your passenger vessel. It confirms that the vessel complies with the applicable technical regulations (stability, fire protection, life-saving equipment, sanitation) and sets the maximum permitted number of passengers. Without a valid certificate no paying guest may be carried. The permitted passenger number is at the same time the most important commercial metric: it caps revenue per trip and therefore the entire business case.
Survey status and next renewal
Passenger vessels are comprehensively surveyed at regular intervals. During this renewal the vessel is dry-docked, and hull, propulsion and safety equipment are inspected and repaired as needed. The date of the next due survey is decisive when buying: an upcoming survey quickly costs a six-figure sum on larger vessels. Vessels with a recently completed survey are considerably more attractive, because the buyer can operate with planning certainty for several years without immediately budgeting high shipyard costs. Always ask to see the last survey report and the date of the next renewal.
Navigation zones: where may the vessel operate?
Inland waters in Europe are classified by zone – depending on possible wave height and weather risk, different structural requirements apply:
- Zone 4 – sheltered inland waters, small rivers and canals. Lowest requirements.
- Zone 3 – larger rivers such as the Moselle, Danube, Elbe or Weser.
- Zone 2 Sea – coastal operation, for example on the Baltic. Higher requirements for stability and equipment.
- Rhine – its own approval via the Central Commission for the Navigation of the Rhine (CCNR).
Be sure to check whether the zone approval matches your intended area of operation. A subsequent zone extension – say from Zone 3 to Zone 2 Sea – involves considerable rebuilding and cost and is not economically viable for every hull.
Checklist before buying
- Valid Union certificate in place – with how much remaining validity?
- Date of the next survey renewal and estimated cost
- Approved navigation zone matching the intended operating area
- Maximum passenger number – does it support your business case?
- Review the last survey / dry-dock report
- Documented modernisations (propulsion, fire alarm system, life-saving equipment)
For every vessel on Navium you will find the approval-relevant key data – year built, approval and passenger number – directly in the listing. View current passenger vessels or get in touch with any questions.
Frequently asked
What is the EU ship certificate?
It is the operating licence of an inland vessel. The former national ship certificate was replaced EU-wide by the Union certificate for inland navigation vessels. It confirms compliance with technical requirements and sets the passenger number and area of operation.
How long is a ship certificate valid?
For passenger vessels usually up to five years. Before it expires a renewed survey is due, which depending on size and condition can cost a six-figure sum.
What do zones 3, 4 and Zone 2 Sea mean?
They classify waters by wave height and weather risk. Zone 4 covers sheltered inland waters and canals, Zone 3 larger rivers such as the Moselle or Danube, and Zone 2 Sea permits coastal operation, for example on the Baltic.
