What it is Filled
A vessel that carries passengers, vehicles and goods across a body of water on a regular service, from small cable ferries and reaction ferries such as the German Ponte that use river current, through car and passenger ferries on rivers, lakes and coasts, to large ro-ro and cruise ferries on sea routes, with fleets such as the Washington State Ferries and modern hybrid and electric ferries; ferries are part of public transport and are regulated for safety after major disasters.
Why it exists Filled
Let an agent explain ferries and their kinds, relay operations, safety regulation and notable systems from maritime sources, describe history and technology including hybrid propulsion, and distinguish ferries from cruise ships and other vessels.
Distinguishing features Filled
- Regular route
- Passenger and vehicle carriage
- Double-ended designs
- Safety regulation
What robots and AI may and may not do Filled
Must not
- Board or load a ferry beyond its certified passenger or vehicle limits.
- Operate or move a ferry without a qualified master in command.
- Ignore or hide weather warnings or safety defects affecting a sailing.
- Discharge fuel or waste from a ferry into the water.
Only with a human decision
- Cancelling or proceeding with a sailing in bad weather.
- Evacuating passengers or changing course in an emergency.
May
- Report ferry timetables, routes and disruption notices from the operator.
- Help passengers book and plan journeys through official channels.
Moral aspects Filled
- Ferry disasters, often from overloading, have killed many passengers.
- Island and coastal communities depend on ferries for essentials and health care.
Who is affected
- Passengers and crew
- Island communities
- Other water users
Owners Filled
Steward
The operator and its master; the flag state registers the vessel and certifies its safety.
Master systems
- Ship registers of the flag state
- International ship identification numbers

What else AI and robots need to interact with it Filled
Identity and identifiers required Filled
- Vercy registry: vr.tr.ferry
- Wikidata: Q25653 (https://www.wikidata.org/wiki/Q25653)
Direct properties required Filled
- Washington State Ferries annual passengers: about 20 million
- first electric car ferry: 2015 year - MF Ampere, Norway
Recognition required Filled
- Vessel on a regular crossing
- Cable, reaction, river, car, ro-ro, cruise, hybrid and electric ferries; fleets such as Washington State Ferries
- Cruise ships carry leisure passengers on voyages; water taxis are on demand; ro-ro cargo ships carry freight only
- A vessel with vehicle decks or passenger cabins, often double-ended.
Capabilities and actions required Filled
- explain kinds
- relay operations and safety
- describe history and technology
- distinguish from other vessels
Hazards and failure modes required Filled
- Capsizing from vehicle deck flooding, as in the Herald of Free Enterprise and Estonia disasters
- Overloading in poorly regulated services
- Stale schedule information
- Confusing ferry types
Standards and interfaces required Filled
- SOLAS and IMO safety rules including the Stockholm Agreement on ro-ro stability
- National passenger vessel regulations
- Emission rules driving hybrid and electric ferries
- Accessibility standards
Context of use required Filled
- Carrying people, vehicles and goods across water on regular routes.
- cable ferries and reaction ferries such as the Puente
- small passenger ferries and river ferries
- car ferries and ro-ro ferries
- fast ferries and hydrofoils
- cruise ferries
- hybrid and electric ferries
- ferry systems such as Washington State Ferries and vessels such as MV Me-Mel
Sources Filled

- Wikipedia: Ferry - general description of the item
Open questions
- Should cable ferry and ro-ro ferry be separate primary entries?
- How should maritime safety sources be linked?
- The registry entry has merged aliases naming fleets and vessels; should they be split off?
