Purpose and description
Enable an AI agent to recognise a marine anchor, assess its suitability and condition, and identify the evidence needed before deployment, recovery or continued use.
An anchor is a device connected to a vessel or other floating structure by a line or chain that resists displacement by engaging the bed of a body of water or relying on its submerged weight.
It can be Classify the anchor's holding mechanism and identify the evidence required for its intended service.; Compare documented bed and load compatibility with a proposed anchoring location.; Check attachment and handling interfaces against the associated anchoring system.; Record deployment and setting evidence without treating contact with the bed as proof of holding.; Assess recovery options and restrictions when the anchor is fouled or embedded.; Use inspection findings and documented limits to recommend continued use, restriction, repair or retirement..
Distinguishing features
Its intended restraint comes from interaction with the bed, unlike a sea anchor or drogue whose resistance comes from moving water.
It provides the bed-engaging or bed-weighting element, unlike a rode that transmits force or a windlass that handles the rode.
It is designed to accept an external restraint load through an attachment interface, unlike ballast carried solely to change a vessel's weight or stability.
It belongs to the marine holding-device sense; resemblance to a construction anchor or use of the same name does not establish membership.

Anchor identity and mechanism Establishes which physical anchor sense and holding mechanism apply.
Marine anchors can hold through substantially different mechanisms, so appearance or name alone cannot determine the appropriate assessment.
Marine sense and service
Separates marine anchoring devices from other meanings and identifies their intended service.
Restraint role
Record what the anchor is intended to restrain and whether it is a temporary or long-term installation.
- Does this entry denote a bed-interacting marine anchor rather than a drogue, construction fastener or nonphysical anchor? boundary
- Which vessel or floating-installation services define the anchor kind's intended use? definition
Holding principle
Identifies the physical interaction responsible for restraint.
Mechanism-dependent evidence
Describe whether restraint depends on penetration, bearing, weight, foundation interaction or a documented combination.
- What physical mechanism transfers the applied restraint force into the bed? definition
- Which design description or observed installation evidence supports that mechanism classification? provenance
Anchor geometry and interfaces Captures the parts and connections that govern bed engagement and force transfer.
Fluke geometry, articulation and attachment details can change setting behaviour and introduce specific interference or failure risks.
Bed-engaging form
Describes the geometry relevant to the identified holding mechanism.
Functional geometry
Record applicable flukes, shank, stock, crown, ballast body or foundation shell, including moving parts.
- Which parts penetrate, bear on or otherwise engage the bed, and which orient them? definition
- What dimensions, areas, angles and articulation limits describe those parts in the deployed configuration? measurement
Load and handling connections
Separates restraint attachment from lifting, recovery and stowage interfaces.
Connection compatibility
Identify each connection's intended function and constraints on connected equipment.
- Which attachment carries the rode load, and what connector dimensions and directions of loading are supported? measurement
- Which lifting or recovery points may be used, and what evidence prevents confusing them with the restraint attachment? action
Bed and load suitability Relates anchor performance evidence to the substrate and applied forces.
Holding capability cannot be inferred reliably from anchor mass or nominal family without bed and loading conditions.
Substrate response
Records conditions that permit or obstruct engagement.
Bed compatibility evidence
Associate supported and unsuitable bed conditions with explicit evidence and uncertainty.
- For which sediment, rock, vegetation or layered-bed conditions is setting and holding supported by evidence? provenance
- What site measurements are needed to evaluate penetration, burial depth or bearing for this anchor mechanism? measurement
Conditional holding capacity
Distinguishes structural strength from demonstrated resistance in a particular bed.
Capacity basis
Keep proof loads, structural limits and bed-holding results separately attributable to their conditions.
- What evidence distinguishes the anchor's structural load limit from its measured or calculated bed-holding resistance? provenance
- What load magnitude, direction, cycling and installation conditions bound each reported capacity? measurement
- What reassessment is required when the load reverses, the rode angle changes or the substrate differs from the evidence? action
Setting and recovery Models the anchor's transition between stowage, engagement, restraint and retrieval.
An anchor on the bed may remain unset, and an anchor that holds successfully may require a distinct breakout or recovery procedure.
Deployment and setting
Tracks prerequisites and evidence for effective engagement.
Verified setting state
Record the setting method and observations that justify a bounded holding assessment.
- What orientation, installation equipment or setting procedure does this anchor require? action
- Which observations or tests distinguish successful setting from simple bed contact, temporary resistance or dragging? measurement
Breakout and stowage
Addresses release from the bed, fouling and secure handling after retrieval.
Recovery constraints
Identify permitted recovery methods and the conditions that make retrieval unsafe or unsupported.
- How is this anchor intended to break out or be removed, and which attachments and load limits govern recovery? action
- What evidence of fouling, abnormal breakout resistance or damage requires recovery to stop for reassessment? action
- What geometry and securing provisions must the associated stowage arrangement accommodate? boundary
Integrity and service evidence Connects anchor-specific deterioration and documentary evidence to service decisions.
Deformation, section loss or restricted articulation can compromise bed engagement or load transfer even when the anchor remains recognisable.
Damage and deterioration
Targets the components and surfaces relevant to holding and structural integrity.
Critical condition observations
Record corrosion, cracks, bent parts, attachment wear and impaired movement against applicable acceptance criteria.
- What section loss, cracking, deformation or attachment-hole wear is present at load-carrying and bed-engaging parts? measurement
- Where articulation is part of the design, does it move through its documented range without seizure or excessive play? measurement
- Which documented rejection or repair criteria apply to the observed defects? action
Qualification and traceability
Identifies the basis and applicability of approvals, tests and service restrictions.
Applicable qualification
Record verified issuing bodies, document editions, approval scope and traceability without assuming one standard governs every anchor.
- Which standards, classification rules or manufacturer requirements apply to this anchor family and intended service, and who issued them? provenance
- What markings and records connect a particular anchor to its material, design approval and required tests? provenance
- Which repairs or modifications require renewed inspection, testing or approval before use? 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.

Recalled without web access and unsourced; every item is a lead to verify.
- Mooring - A mooring is the securing arrangement or system; an anchor can be one component of it.
- Anchor rode - The rode is the line, chain or combination transmitting load between the vessel and the anchor.

What the second pass must settle
- Does vr.tr.anchor specifically denote a marine anchor, and does an existing Vercy world model already own this concept?
- Does the registry intend deadweight moorings, suction anchors and other permanently installed marine foundations to be included or linked as neighbouring kinds?
- Which primary sources establish substrate compatibility and conditional holding performance for the anchor families retained in scope?
- Which standards and issuing bodies apply to each intended service, including required tests, markings and inspection criteria?
- What evidence is sufficient to record holding as verified, and how should that assessment expire after load changes, dragging or relocation?
