Purpose and description
Enable an AI agent to recognise a yacht, assess its fitness for an intended voyage or use, and identify actions supported by its condition, equipment and operating constraints.
A yacht is a sailing or motor vessel designed or used primarily for recreational cruising or racing, including private and charter use, with no universally accepted size threshold separating it from other pleasure craft.
It can be Match the yacht to a proposed passage, anchorage or berth using documented dimensions and operating constraints.; Assess whether persons, stores and equipment fit supported loading and capacity limits.; Identify inspection, maintenance or repair actions needed before the intended use.; Estimate fuel, electrical energy and water sufficiency using explicit passage assumptions and reserves.; Check whether onboard equipment and vessel documentation support the proposed private, charter or racing operation.; Record a refit and identify which dimensional, performance and readiness assessments require revision..
Distinguishing features
Check intended and actual pleasure, cruising or sporting use; size or a luxurious appearance alone does not establish yacht identity.
Distinguish a yacht from a passenger or work vessel through its design brief, configuration and documented operating role; carrying paying guests alone does not settle the boundary.
Identify whether a small craft is independently treated as a yacht or serves as a tender to another vessel.
Treat sailing yachts and motor yachts as configurations within scope; the presence of a mast, engine or cabin alone is insufficient.
Separate the individual vessel from its builder's model designation: sister yachts may have different refits, equipment and operating constraints.
Scope
+ Vessel identity, intended use and evidence supporting classification as a yacht
+ Hull, appendages, propulsion, steering and sailing configuration
+ Accommodation, onboard services and capacity constraints
+ Condition, maintenance needs and readiness for a specified passage
+ Vessel-specific documentation, equipment and operating limitations
- The general boat or ship model, except where its properties constrain yacht use
- Ownership companies, charter businesses and purchase or charter contracts
- Crew qualifications and employment as independently modelled records
- Voyages, regattas and navigation plans as activities
- Marinas, berths and shore facilities as separate infrastructure
Characteristics
- Vessel identity
- Links to builder, build record, hull identifier and applicable registration records Keeps records attached to the same vessel through renaming, sale and refit.
- Operating role
- Private recreation, charter, racing, mixed use or unresolved; with evidence and date Defines the intended use against which readiness and applicable requirements must be assessed.
- Propulsion configuration
- Sail, motor or combined; record installed systems and their roles Determines manoeuvring options, energy dependencies and failure responses.
- Principal dimensions
- Length, beam, draft and air draft in metres, with measurement convention and configuration Supports berth, channel, bridge and haul-out compatibility checks.
- Displacement and loading
- Kilograms or tonnes, with loading condition and measurement or calculation basis Connects stores, equipment and persons aboard to draft, performance and stability assessment.
- Persons and accommodation capacity
- Counts of berths and documented persons limits, separately recorded with operating conditions Prevents sleeping capacity from being mistaken for an authorised or safe persons limit.
- Passage endurance
- Nautical miles or hours under stated speed, weather, loading, consumption and reserve assumptions Supports passage feasibility without treating a nominal range as guaranteed.
- Readiness for intended use
- Unassessed, ready within stated limits, restricted or unavailable; with evidence and assessment date Makes readiness specific to the proposed operation and unresolved defects.

Yacht identity and role Establishes which vessel is being modelled and why yacht is the appropriate category.
Yacht identity depends on use and configuration, while vessel names and commercial arrangements can change.
Individual vessel
Separates the physical yacht from names, design families and associated craft.
Persistent vessel identity
Record evidence linking the yacht's current name and configuration to its build and registration history.
- Which hull, builder or registration identifiers establish this individual yacht's identity? provenance
- Which records describe this hull, rather than its design class, sister yacht or tender? boundary
Pleasure, sport and charter role
Captures intended use and the evidence behind the yacht classification.
Supported yacht classification
Record design intent, actual use and documented vessel category without inferring classification from appearance.
- What evidence supports treating this vessel as a yacht rather than a workboat, passenger vessel or auxiliary tender? definition
- Does the proposed operation differ from its documented private, charter or sporting role? boundary
Hull, rig and manoeuvring Captures the yacht's floating structure, clearance envelope and means of movement.
Keels, rigs, hull arrangements and propulsion choices create yacht-specific passage and handling constraints.
Hull and clearance envelope
Records dimensions and appendage configurations relevant to water depth, overhead clearance and berthing.
Configuration-dependent clearances
Associate draft, beam and air draft with loading, rig and any movable appendages.
- What are the yacht's draft, beam and air draft in the configuration proposed for the passage? measurement
- Which keel, centreboard, mast or other configuration changes alter the clearances that must be checked? action
Propulsion and control
Records sail plans, engines, drives and steering needed to control the yacht.
Available manoeuvring options
Distinguish installed propulsion and steering systems from those available and usable under current conditions.
- Which sails, engines, drives, thrusters and steering systems are installed and currently serviceable? measurement
- What supported manoeuvring or return options remain if the primary propulsion or steering system fails? action
Life aboard and endurance Relates people, accommodation, stores and service systems to a proposed period afloat.
A yacht's cruising capability depends on usable resources and loading, beyond the presence of cabins or tanks.
Persons and loading
Separates accommodation provision from supported persons and loading limits.
Supported occupancy and stowage
Record berths, applicable persons limits and the distribution of people, stores and carried equipment.
- How many usable berths are fitted, and what separate evidence establishes persons limits for the intended operation? provenance
- How do the proposed people, stores, tender and deck equipment compare with documented loading and stowage constraints? measurement
Onboard resource balance
Connects fuel, electricity, freshwater and waste capacity to time away from shore support.
Conditional cruising endurance
Express endurance as an estimate with consumption, production, usable capacity and reserve assumptions.
- What usable fuel, battery energy, freshwater and waste capacity are available at departure? measurement
- Under the proposed passage and hotel loads, which resource first requires replenishment, discharge or reduced consumption? action
Condition and operating readiness Combines physical condition, emergency provisions and documentary constraints for a specified use.
A yacht may be habitable or operable at a berth while lacking the condition or provisions needed for a passage.
Condition and refit history
Tracks inspections, defects and modifications affecting the yacht's structure and essential systems.
Evidence-based condition
Tie readiness assessments to dated observations of the hull, water ingress paths, propulsion and rig where fitted.
- What dated inspection or maintenance evidence supports the condition of the hull, seacocks, steering, machinery and rig where fitted? provenance
- Which unresolved defects or refits require repair, inspection or reassessment before the intended passage? action
Passage and emergency readiness
Checks emergency capability and vessel-specific operating constraints against the intended voyage.
Supported departure decision
Record whether emergency equipment, vessel documents and stated limitations support departure, with unresolved gaps explicit.
- What evidence establishes the suitability and service status of lifesaving, fire, bilge, navigation and communication equipment for those aboard and the proposed passage? provenance
- Which documented limits, missing records or equipment deficiencies prevent or constrain the proposed departure? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.
