jetty
Let an agent explain jetties and their kinds, relay design, construction and uses from coastal engineering and port sources, describe ferry stops and wharfboats, and distinguish jetties from piers, wharves, breakwaters and groynes.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

What it is Filled
A structure projecting from the shore into a body of water to serve as a landing place for boats, to protect a harbour or channel, or to influence currents and sediment, built of timber, stone, concrete or steel, and in the registry sense including ferry stops and landing stages such as wharfboats, floating hulls moored as landings; jetties for mooring are also called piers or landing stages, while jetties at river mouths and inlets are training walls that keep channels open.
Why it exists Filled
Let an agent explain jetties and their kinds, relay design, construction and uses from coastal engineering and port sources, describe ferry stops and wharfboats, and distinguish jetties from piers, wharves, breakwaters and groynes.
Distinguishing features Filled
- Projects from shore
- Landing or channel control
- Fixed or floating
- Varied materials
What robots and AI may and may not do Filled
Must not
- Moor or operate vessels at a jetty without the operator's permission.
- Encourage people onto a jetty during storms or high waves.
- Remove or disable life rings, rails or warning signs.
Only with a human decision
- Closing a jetty or approving repairs.
- Building or altering a jetty that changes currents and sediment.
May
- Describe jetties and their uses for landing, harbour protection and sediment control.
- Report damage, scour or unsafe surfaces to the operator.
- Distinguish jetties from piers, wharves and groynes.
Moral aspects Filled
- People drown from falls off jetties, especially in rough weather.
- Jetties change coastlines and affect neighbouring beaches.
Who is affected
- Users and anglers
- Boat crews
- Neighbouring coastal communities
Owners Filled
Steward
The harbour authority or owner of the structure.
Master systems
- Harbour and coastal works registers
Links to other meta-models Filled

- Q811979 - registry parent class
related
- built structure - in registry terms
- ferry - as a stop
- pier - often larger and recreational
- breakwater - which shelters harbours
What else AI and robots need to interact with it Filled
Identity and identifiers required Filled
- Vercy registry: vr.tr.jetty
- Wikidata: Q2240172 (https://www.wikidata.org/wiki/Q2240172)
Direct properties required Filled
- materials: timber, stone, concrete, steel list
- inlet jetty lengths: hundreds of metres to kilometres range
- wharfboat: moored hull used as landing note - Mississippi tradition
Recognition required Filled
- Structure projecting into water for landing or channel control
- Landing jetties, ferry stops, wharfboats, inlet jetties and training walls
- Piers are often larger promenades; wharves run along the shore; breakwaters shelter harbours; groynes trap sand
- A narrow structure extending from shore into water, on piles or rubble.
Capabilities and actions required Filled
- explain kinds and functions
- relay design and construction
- describe ferry stops and wharfboats
- distinguish related structures
Hazards and failure modes required Filled
- Storm damage and scour
- Confusing jetties with piers, wharves and groynes
- Falls and drowning at public landings
Standards and interfaces required Filled
- Port and marine structure design standards such as PIANC and BS 6349
- Navigation and coastal permits
- Safety rules for public landing stages
Context of use required Filled
- Landing boats and controlling water.
- landing jetties and landing stages
- ferry stops and river landings
- wharfboats and floating landings
- inlet and river mouth jetties as training walls
- oil and bulk loading jetties
- recreational and fishing jetties
Sources Filled

Open questions
- Should wharfboat and training wall be separate entries?
- How should coastal engineering sources be linked?
- How should regional terminology differences be recorded?
