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.

Purpose and description
Enable an agent to recognise a steamboat, assess its propulsion and operating condition, and identify what evidence and permissions are needed before it can be operated, maintained or preserved.
A steamboat is a vessel propelled by a steam engine or steam turbine that converts energy from steam into mechanical work driving paddle wheels, a propeller, or another water propulsor.
It can be Classify a vessel's steam-propulsion identity using documented machinery and power-path evidence.; Compare a proposed route and loading condition with recorded draught, clearance and manoeuvring constraints.; Identify missing inspection, crew or operating-limit evidence before referring a departure decision to the responsible operator.; Track fuel and feedwater availability against a documented voyage consumption estimate.; Prioritise inspection or maintenance of reported boiler, feed-system, transmission and propulsor defects.; Evaluate restoration or conversion proposals against operating goals and documented historical configuration..
Distinguishing features
Steam must contribute to propulsion: carrying a steam boiler solely for heating or auxiliary work does not establish a vessel as a steamboat.
A paddlewheel is insufficient evidence: record what actually drives it, since appearance alone does not establish steam propulsion.
The object is a waterborne vessel with an integrated propulsion arrangement, rather than a stationary steam engine or floating boiler installation.
Separate an operational steam vessel from a former steamboat converted to another propulsion system or preserved without a working plant.
Do not infer a river-only role, wooden hull or paddle propulsion from the name; establish hull material, operating waters and propulsor independently.

Characteristics
- Steam-propulsion identity
- currently steam-propelled | originally steam-propelled | steam auxiliary only | unverified Separates the defining propulsion relationship from historical naming and incidental steam equipment.
- Prime mover and transmission
- documented engine type and mechanical or electrical path to the propulsor; unknown where unverified Determines how steam power becomes thrust and exposes terminology questions around turbine or steam-electric vessels.
- Propulsor arrangement
- side paddlewheels | stern paddlewheel | screw propeller arrangement | other documented arrangement Supports assessment of manoeuvring, immersion requirements and exposed moving machinery.
- Boiler pressure condition
- current pressure and documented allowable pressure in kPa or bar, explicitly identified as gauge or absolute Allows operating readings to be interpreted against the limits of the installed boiler.
- Fuel and heat source
- documented fuel or external heat source, firing method and storage arrangement Shapes endurance, replenishment, fire controls and historical authenticity.
- Feedwater and condensate arrangement
- condensing | non-condensing | mixed or modified; documented feedwater source and treatment Determines water demand and which water-quality and feed-system evidence is needed.
- Loaded draught
- m at a stated loading condition Connects vessel loading to waterway clearance and propulsor immersion.
- Steam-plant readiness
- cold | raising steam | ready under documented criteria | operating | shut down | laid up | disabled | unknown Prevents installed machinery from being mistaken for machinery ready to propel the vessel.
- Propulsion configuration provenance
- vessel linked to dated machinery records, surveys, conversion records and physical observations Keeps original construction, replacement machinery and present condition distinguishable.

Steam vessel identity Establishes why the vessel belongs to this registry entry and which configuration is being described.
Names, decorative paddlewheels and historical associations can conceal the actual propulsion system.
Propulsion boundary
Tests whether steam supplies vessel propulsion.
Steam-to-thrust evidence
Record the evidenced connection between steam machinery and the device producing thrust, including any intervening transmission.

- Is steam used for propulsion, auxiliaries alone, or only represented by retained historical equipment? boundary
Configuration history
Separates original construction from later conversions and the present vessel.
Dated propulsion configurations
Associate each propulsion description with a date and evidence rather than treating the vessel's name as a permanent technical classification.
- What records establish the original steam plant and subsequent machinery replacements or conversions? provenance
- Does the current physical configuration support the same classification as the vessel's historical name? boundary
Steam generation and use Describes the installed steam cycle, its supplies and its documented operating limits.
A steamboat's propulsion depends on a functioning heat, water and steam system whose condition cannot be inferred from hull condition.

- Which feedwater, condenser or engine defects require attention before the plant can meet its documented readiness criteria? action
Hull, propulsor and waterway Connects the steam plant's power delivery to vessel motion and operating waters.
Propulsor geometry, machinery loading and waterway conditions determine whether available steam power can produce useful and controllable movement.

Recalled without web access and unsourced; every item is a lead to verify.
- steamship - Usually denotes a larger steam-powered vessel; the distinction from steamboat is conventional rather than a precise technical size boundary.
- paddle steamer - Requires steam propulsion through paddle wheels; a steamboat can instead use a screw propeller.
- paddle boat - Describes a vessel using paddles or paddle wheels without necessarily specifying steam as its power source.
- motorboat - In ordinary technical usage, uses an internal-combustion engine or electric motor rather than a steam engine.
- steam engine - Is the power-producing machinery, not the vessel that carries and uses it.

What the second pass must settle
- Does the registry intend steamboat to cover all steam-propelled vessels, or a narrower class distinguished from steamship, particularly for turbine and steam-electric propulsion?
- Is PHY.LIV a classification error for this entry, and which physical-artifact domain should own it?
- Does an existing Vercy vessel or steamship model already cover this concept, requiring a link or extension rather than a separate publication?
- How should converted vessels and non-operational museum examples retain historical steamboat identity while exposing their present propulsion state?
- Which authoritative vessel, boiler and maritime sources should ground the researched publication and its jurisdiction-dependent operating requirements?
