What is Vessel Registration?
In the UK, vessels under 24 metres in load line length can be registered under either:
• Part I of the UK Ship Register – suitable for both commercial and leisure vessels, including those operating internationally
• Part III, known as the Small Ships Register (SSR) – designed for UK-based leisure vessels only
Part III – Small Ships Register (SSR)
The SSR is a simplified form of registration available to individuals who are ordinarily resident in the UK and who use their vessel solely for pleasure. It is quick and low-cost but has some limitations:
- Only available for vessels under 24 metres in load line length
- No proof of ownership is recorded
- Not valid for commercial use
- May not be recognised by all foreign authorities, particularly outside nearby European waters
- Most suitable for short sea routes, such as crossing the Channel to the near continent
Part I Registration
Part I registration is a more comprehensive and internationally recognised form of vessel registration. It is available to both private and commercial vessels and offers several advantages:
- Suitable for international voyages and required for most commercial operations
- Provides evidence of legal title and ownership
- Allows the vessel to be mortgaged
- Required for coding under the Small Commercial Vessel Codes
- Valid for 5 years, with re-registration required upon expiry
Although no further survey is required at renewal, a new Certificate of Survey for Tonnage and Measurement will be needed if there are significant modifications to the vessel, for example, a change of engines or major structural alterations.

What is Tonnage?
Tonnage is a measure of a vessel’s internal volume, not its weight. It is used to calculate registration fees, determine regulatory requirements, and establish a vessel’s classification under UK and international maritime rules.
