Sea passenger statistics: notes and definitions

Published 29 July 2026

These statistics present all sea passenger movements to and from the UK on both domestic and international routes. 

The statistics support the work of the DfT Maritime Directorate, including the Security and Resilience Programme. They also support the ONS International Passenger Survey. 

Short sea, long sea and cruise data are collected under the Statistical Returns Carriage of Goods and Passengers by Sea) Regulation 1997 SI 1997 No: 2330 covering the carriage of goods and passengers by sea. 

Publication information 

Sea passenger statistics: all routes

This statistical release is published in July following the calendar year end to which the data relates and includes: 

• international long sea routes 

• international cruises 

• domestic short sea minor routes 

• domestic river crossings 

• domestic inter-island routes 

• domestic cruises 

Provisional international short sea passenger figures are published 6 weeks after the month end to which the data relates. 

All sea passenger statistics are published through the maritime and shipping series. 

Definitions 

Short sea routes: all ferry routes between Great Britain or Northern Ireland and the rest of Europe. 

Long sea routes: all one-way scheduled voyages to and from ports outside Europe and the Mediterranean. Passengers traveling on cargo vessels (one-way) are not included. 

Cruises: includes all passengers on international cruise journeys who embark or disembark their cruise journey at a UK port. Cruise passengers are included at both departure and arrival if their journey begins and ends at a UK seaport. Passengers passing through on transit calls are not included in these figures. 

Short sea routes: these can be major or minor routes 

Inter-island routes: routes between the mainland and UK islands, such as Isle of Skye and the Isle of Wight. Also included are internal ferry routes on lochs such as Strangford to Portaferry in Northern Ireland. 

River ferries: inland waterway routes with over 500 passenger kilometres on vessels of over 100 gross tonnes, travelling distances greater than 500 metres on a single ferry. 

Domestic cruises: Domestic cruise passenger figures include all passengers on domestic cruises in the UK (no cruise stops at foreign ports). These figures can be found in table SPAS0201. Large domestic cruises did not previously occur but were a feature in 2021 when they were permitted under the domestic roadmap for England. This was the first stage of the wider restart of cruise following the industry’s pause during the coronavirus pandemic, with international cruises restarting from August 2021. 

Short sea routes can either be: 

Major routes: routes between Great Britain, Northern Ireland, Isle of Man, the Channel Islands. 

Minor routes: all other short sea routes, including routes between Great Britain and the Orkney and Shetland Islands. 

Collection and methodology 

Short sea passengers 

Data is collected from ferry operators for vessels over 100 gross tonnes, and validated on a monthly basis. Passengers counted include drivers of lorries, coaches and other vehicles and their passengers. At the end of the reference year, the annual data is validated for a final time for publication. 

The monthly short sea collection is a statutory return collected under the Statistical Returns Carriage of Goods and Passengers by Sea Regulations 1997 (S.I. No. 2330). 

International passenger numbers collected include passengers on routes beginning or ending in Great Britain or Norther Ireland. Routes with foreign countries beginning or ending in the Channel Islands or Isle of Man are not included. 

Some passengers used to travel between Great Britain and St Malo in France by going to the Channel Islands on one vessel and then transferring to another. Prior to 2016, where these passengers could be distinguished from other traffic, they were subtracted from the domestic route with the Channel Islands and added to the direct international route between Great Britain and France. From 2016 onwards, these passenger numbers were attributed to the domestic route with the Channel Islands rather than the direct international route. The main routes affected were the Poole to St Malo route and the Weymouth to St Malo route. In recent years, these routes accounted for less than 0.1% of the total international short sea traffic and received no passengers in 2024. 

Inter-island ferry passengers 

Data from crossings between the Channel Islands is collected and validated as part of the monthly short sea passenger collection, described above. 

Data for crossings to Orkney and Shetland and Scottish inter-island routes is annually supplied by the Scottish Government. These data sets are checked in detail by the Department for Transport statisticians and considered to be very robust. Occasionally, data is revised in response to further information being submitted later in the year. 

Some of the routes provided by the Scottish Government are not included in the final database as they do not meet the set criteria. For example, information relating to the Appin to Lismore route and the Camusnagaul to Fort William is not included as the vessels used are under 100 gross tonnes. 

International cruise, domestic cruise and long sea passengers 

Data is supplied by operators, typically on annual basis and is regularly reviewed. 

Occasionally, a small amount of data is imputed where operators do not provide returns. The data are considered to be fit for purpose- comparison with industry figures show similar trends although the annual totals can differ. 

Long sea passenger numbers can fluctuate greatly over time, in part because operators can use these trips to reposition vessels around the world as needed. Data supplied by operators are compared against ship schedules to ensure long sea voyages are not incorrectly entered as cruise voyages, and vice versa. 

River ferry passengers 

Data is collected annually from operators and council government sources. 

Data is only collected on inland waterway routes with over 500 passenger kilometres on vessels over 100 gross tonnes, travelling distances greater than 500 metres in a single ferry. 

Although there have been occasional changes in operator reporting methods, the data are considered to be fit for purpose. 

These routes are not covered by the legal requirement to provide data on passengers on sea crossing routes. Operators are not legally required to provide us with this data. 

Every 5 years, the ‘non-survey’ routes are updated. These are only used to calculate passenger kilometres and are not part of the normal collection or outputs. 

Occasionally, data is imputed where operators do not provide returns. This imputation is based on the missing company’s previous data and is ensured to be in line with the overall expected trend.
