Result of the comparison

Area 01 · Ordering and point of contact

Task described in the material: station. The material is silent about: pilot boat, pilot — this is a gap in the description, not evidence that nobody does it.

Changing the position does not change the area. Symbols on the area buttons: station, pilot boat, pilot, port authority (filled — task, half — mentioned, hatched — the material is silent, dotted — outside the scope of the material). The left and right arrow keys, Home and End move the selection within the group.

Area 01

Educational diagram: the pilot station on the quay and a small port authority building. A symbol of a function, not to scale.

Station pilot station dispatcher

Task described in the material

What the material says

According to the UNIPIL description, the station is the point of contact in organising the pilotage service.

What we do not know

The material does not specify how contact with the ship works in practice or what data are needed before a pilot is assigned.

Area 01

Educational diagram: the pilot boat as a symbol of a function (not Pilot V, not any particular vessel). The circle with a question mark is a handover place that we do not know.

Pilot boat skipper of the pilot boat, auxiliary vessel

The material is silent — a gap, not zero

What the material says

The pilot boat is an auxiliary vessel; the material assigns it only the general function of carrying the pilot, with no description of the ordering stage.

What we do not know

It is not known at what stage the crew of the pilot boat learns of the need for transfer and of readiness to depart.

Area 01

Educational diagram: a ship with containers and a bridge, and a figure of the pilot. A symbol of a function, not to scale.

Pilot sea pilot, on the ship

The material is silent — a gap, not zero

What the material says

The pilot is a person who goes aboard a ship to assist with navigation; the material does not describe his or her part in accepting the order.

What we do not know

A question for a practitioner: when does the pilot learn of the assignment, and does he or she take part in the arrangements before boarding the pilot boat?

How to read the drawing. This is the page author’s educational diagram — not a photograph and not a record of a real operation; there is no material from a single completed operation. The pilot boat and the ship are symbols of functions, not portraits of vessels (including Pilot V), and scale and distances are not preserved. Orange marks the active area. The dashed line is a contact channel that the material does not describe. The circle with a question mark is a handover place that we do not know — not a point on a map. Basis of the role descriptions: sources (with a note of what needs checking).

Information gap in this area

Organising the order

The material presents the UNIPIL station solely as a point of contact in organising the service. It gives no deadlines for requests, communication channels or division of duties when an order is accepted. The dashed line in the diagram therefore marks a channel that the source does not describe.

Map of gaps

Where the material assigns a task and where it is silent

Choose a table cell to see what the material says about a given role in a given area. The choice also sets the panels at the top of the page.

The map requires JavaScript. The same information, in full, is in the source table.

Symbols

Task — the material explicitly assigns this role a task in this area.
Mentioned — the role appears, but with no task assigned.
Silent — the material says nothing. This is a gap in the description: not zero and not “does nothing”.
Out of scope — an entity outside the three panels; the material describes it only in area 4. This does not mean that anyone investigated it and found nothing.

Why the symbols line up along the diagonal

In each of the four areas the material has one performer of the task: the station, the pilot boat, the pilot or the port authority. That is how the descriptions record it, not proof that in practice everything happens exactly like this. The rest of the field is questions for practitioners.

What this is and what it is not

The classification is an editorial reading of the descriptions collected in the previous version of the page (V2). It has not been confirmed by the operators and is not an assessment of how pilotage works today.

History of a vessel · not a diagram of roles

One hull, three names

1936

Pilot V

The Polish Navy Museum describes a vessel built by the Gdynia Shipyard for the Maritime Office.

April 1945

Korsarz

A naval ensign was raised on the recovered boat and it was given the name Korsarz.

1946

Pilot 4

Returned to the maritime administration, again a pilot boat — according to the museum’s history until 1977.

This chronology concerns one historical vessel. It does not document any present-day ship arrival and does not describe today’s fleet or procedures. The material lacks a photograph of Pilot V under a known licence, so there is no image of this boat here — the diagram in the first section is a general symbol of a function, not its portrait.

Limits, changes since V2 and sources

What this page does not do

It is not an instruction for handling a ship or manoeuvring.
It gives no times, radio messages, communication channels or hydrodynamic parameters.
It contains no simulator or scoring.
It does not indicate the real place where the pilot is handed over.
It does not settle the relationship between the ship’s master and the pilot on the bridge — the material does not describe it.

To be confirmed by the operators

The scope of data that may be published, and whether the roles are assigned correctly.
Material from a single completed operation, with the consent of interviewees and transcripts — there is none today, which is why the scene is a diagram.
Whether the description of the historical boat has any connection with today’s fleet — by default it has none.

What changed since V2

Removed the exercise with four drop-down lists (“Check the division of work”). It was replaced by the map of gaps and a captioned scene: the answers do not have to be guessed, they are visible at once, and their limits are described.
Removed saving in the browser (localStorage) and the button for clearing it — nothing is stored on the device any more.
Removed the photograph of leading lights loaded from the internet. The V2 caption itself said that it shows neither Pilot V, nor a pilot boat, nor the handover place, and the page was meant to work offline.
Kept the four timeless areas, the three perspectives, the distinction between “what the material says” and “what we do not know”, and the history of Pilot V as a separate part.
Changed the perspective filter: by default all three are visible at once, and choosing a position narrows the columns instead of hiding them.

Source table: all areas and positions with full descriptions

Four areas and four entities: what the material says and what we do not know
Area	Station	Pilot boat	Pilot	Port authority
AREA 01Ordering and point of contactGap The material presents the UNIPIL station solely as a point of contact in organising the service. It gives no deadlines for requests, communication channels or division of duties when an order is accepted. The dashed line in the diagram therefore marks a channel that the source does not describe.	Task described in the material What the material says According to the UNIPIL description, the station is the point of contact in organising the pilotage service. What we do not know The material does not specify how contact with the ship works in practice or what data are needed before a pilot is assigned.	The material is silent — a gap, not zero What the material says The pilot boat is an auxiliary vessel; the material assigns it only the general function of carrying the pilot, with no description of the ordering stage.

What we do not know A question for a practitioner: when does the pilot learn of the assignment, and does he or she take part in the arrangements before boarding the pilot boat?	Outside the scope of the material The material does not describe this entity in this area.
AREA 02Transport on the water and approachGap The page’s model does not indicate the real place or method of handing over the pilot. The material contains no description of the approach to the ship or of technical requirements. The dashed circle with a question mark marks a place that we do not know — it is not a point on a map.	The material is silent — a gap, not zero What the material says In the material, the station’s role is limited to coordinating the service; the description does not assign it direction of the transfer on the water. What we do not know A question for a practitioner: does the dispatcher track the pilot boat’s position on the roadstead as it happens, or rely on the skipper’s independence?	Task described in the material What the material says The pilot boat serves the general function of an auxiliary vessel that carries the pilot. What we do not know The material does not settle what the approach to the ship’s side looks like, how the pilot is handed over, or how the pilot boat behaves after the handover.	Role mentioned, no task What the material says A person using the pilot boat’s transfer to go aboard the ship — in this area not the performer of the task. What we do not know The material does not document the technical conditions of boarding or the criteria for judging whether boarding is safe.	Outside the scope of the material The material does not describe this entity in this area.
AREA 03Navigational assistance on the shipGap The material defines the pilot as a person who goes aboard a ship to assist with navigation. It does not describe how this assistance proceeds or the relationship with the ship’s command — this page does not settle who decides on the bridge.	The material is silent — a gap, not zero What the material says The service coordinator ashore; the material does not assign the station any part in the ship’s direct navigation. What we do not know Unresolved: whether and how the station records the start and end of the pilot’s presence on board.	The material is silent — a gap, not zero What the material says An auxiliary vessel on the water; in the material its function concerns transfer, not navigation on the ship. What we do not know A question for a practitioner: what tasks does the pilot boat have once the pilot is already on board the ship being served?	Task described in the material What the material says A person who goes aboard a ship to assist with navigation. Not a navigational mark and not an auxiliary vessel. What we do not know An open question: the material does not specify the formal division of responsibility between the pilot and the ship’s master.	Outside the scope of the material The material does not describe this entity in this area.
AREA 04Deviations from the standard areaGap The UNIPIL description takes into account the role of the port authority in deviations and notes that the conditions depend on the ship. A procedure and decision criteria are missing. The fourth participant — the port authority — has no panel of its own; in the diagram it is the small building with a flag on the left side of the first panel.	The material is silent — a gap, not zero What the material says The UNIPIL description mentions the role of the port authority in possible deviations concerning the handover place; it does not assign the station itself a task in this area. What we do not know Unresolved: what the dispatcher’s role is in the circulation of a request to change the place where the pilot is handed over.	The material is silent — a gap, not zero What the material says The pilot boat carries out the transfer; the material does not mention its authority to decide on deviations. What we do not know A question for a practitioner: how does the pilot boat’s crew signal that it cannot reach the standard place?	Role mentioned, no task What the material says A participant in the operation; deviations concern the place where he or she is handed over to the ship and depend on the conditions of the particular vessel. What we do not know Unresolved: whether the pilot has the right to refuse to board and how a change of area is formally agreed with the harbour master.	Task described in the material What the material says The UNIPIL description takes into account the participation of the port authority (the harbour master) in deviations concerning the handover place; the conditions depend on the particular ship. What we do not know A procedure and decision criteria are missing.
