Welded-aluminium petrol-outboard recreational motor vessel manufacture

1. Scope and Applicability

This candidate PCR covers new complete welded-aluminium monohull recreational motor vessels with installed petrol four-stroke outboard propulsion and declared rigging/outfitting. It narrows CPC49490. Exclude inflatable craft, sailing/rowing/canoes, personal watercraft, commercial/passenger/professional vessels, bare hulls, inboard/sterndrive/diesel/electric configurations, other hull materials, separate transport trailers and repairs/conversions/services. One accepted finished unit means one complete boat; Chinese 设备 carries the same measurement meaning.

Collect actual stock/hull receipt, fabrication/joining, conditional finishing, outboard rigging/outfitting, construction commissioning and accepted builder-gate delivery. Later recreational trips, owner fuel and accessories, maintenance, end of life and new-model research tests are excluded. No brochure model weight, speed, power, development-test duration, lifetime or fuel factor is adopted. Manufacturer sources establish possible architecture/configuration only; actual factory routes and upstream supplier links are required before a complete cradle-to-gate claim. Scientific review remains pending. [Sources: buster-welding-2022; buster-xl-config; anytec-owner]

3. Reference Flow

Field	Value
What	Manufacture the declared complete configured recreational motor vessel
How much	1 kg accepted net vessel output, with per-vessel exchange records divided by actual M
How well	Meet actual hull/weld tightness, outboard mounting/steering/fuel/electrical and fitted safety/functional release criteria under documented configuration-specific conditions. Equal mass does not imply equal passenger capacity, boat handling or travel service. No manufacturer marketing specification is imposed universally.
How long or cycle	One manufacture and construction-acceptance cycle; no assumed operating lifetime
reference_flow_link	finished_machine

Field	Value
Reference amount	1
Reference product flow	Accepted complete welded-aluminium petrol-outboard recreational motor vessel
Reference flow property	Mass 93a60a56-a3c8-11da-a746-0800200b9a66
Reference unit group	Units of mass 93a60a57-a4c8-11da-a746-0800200c9a66
Reference unit	kg
Required qualifiers	builder/model and hull serial; drawing/BOM revisions; welded aluminium monohull, alloy/temper and supplied hull completeness; installed petrol four-stroke outboard number/serial, mounts/propeller, steering and rigging; actual deck/seat/glass/foam/electrical/safety configuration, coatings and retained working fluids; actual assembly/acceptance criteria and corrected net delivery state; positive M kg from controlled acceptance records with current actual physical weight/lightship inspection, calibrated traceable inputs and signed itemized mass reconciliation; exclude persons, fuel/fresh water/ballast/test loads, trailer, removable protection and loose spares; actual factory/site/period, supplier boundaries and gate

M is the controlled actual net mass of this complete accepted configuration, including installed hull, outboard drive and boat outfitting, actual retained lubricating/hydraulic working fluids and integral delivered parts. Exclude temporary test load, persons, consumable fuel/fresh water/ballast, temporary trial weights and transport trailer, spares, protection and external support craft. Do not equate survey displacement or catalogue tonnage with net M; retain current original physical lightship/weight inspection and itemized measured corrections to the exact net delivery scope below. No whole-ship platform scale is assumed.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
reference_mass	reference product	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	M = accepted net mass of one complete unit of the same configuration in kg; collect using cp_mass.
mass_record_provenance	controlled acceptance mass records	Mass	kg	Controlled acceptance mass is an acquisition interface, not proof of measurement. Require current original actual lightship/weight inspection, serial/configuration and delivery-state records, a traceable measured/checking method and itemized mass balance. Reconcile additions/deductions and installed service fluids to this PCR net scope. Where physically feasible, retain calibrated load-cell/weighing records and measured fixture/support tare for the actual complete boat or reconciled components; no whole-ship platform scale is prescribed. For afloat-survey-derived records retain observed draught/freeboard, actual water density, verified hull hydrostatics, instrument calibration and measured temporary/tank contents; no uncorrected displacement or design estimate replaces net M. The historical Norwegian procedure is a method example, not a current universal legal threshold. [Source: nma-lightship]
installed_scope	outboard; outfitting	Mass	kg	Preserve independently measured installed assembly masses and supplier inclusions for net M; a complete outboard includes its powerhead/gear/propeller only as supplied. Do not add included constituents or supplier-prefilled fluids again. Catalogue dry hull and nominal engine mass cannot replace accepted complete configuration mass. The historical Anytec manual distinguishes empty boat without engine, empty boat with engine, trailering with fuel/liquids, and maximum loaded conditions: none is automatically this PCR net M.
energy_conversion	electricity	Net calorific value	MJ	Actual measured kWh converts by verified unit identity 3.6 MJ/kWh; retain intake voltage and site route. Engine/motor nameplate kW is not measured energy.
formulation_mass	liquid formulations	Mass	kg	Weigh the actual coating base, hardener, fuel or service-fluid formulation separately. Volume-to-mass requires measured density at declared composition/state/temperature; no tank capacity or brochure coating coverage factor.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Received specified stock/fabricated hulls and machinery/outfitting modules, with actual supplier inclusions
starting_condition_role	Foreground receipt-to-accepted-vessel delivery manufacture
product_classification_scope	Welded-aluminium petrol-outboard recreational motor vessel with installed rigging/outfitting
recursive_input_rule	No complete recreational motor vessel recursively generated as its own input; bought-in finished hulls/modules bypass included operations
upstream_dataset_requirement	Match actual grades/formulations/module completeness/outboard drive, period/geography and property; disclose missing supplier production
disclosure	builder/model and hull serial; drawing/BOM revisions; welded aluminium monohull, alloy/temper and supplied hull completeness; installed petrol four-stroke outboard number/serial, mounts/propeller, steering and rigging; actual deck/seat/glass/foam/electrical/safety configuration, coatings and retained working fluids; actual assembly/acceptance criteria and corrected net delivery state; positive M kg from controlled acceptance records with current actual physical weight/lightship inspection, calibrated traceable inputs and signed itemized mass reconciliation; exclude persons, fuel/fresh water/ballast/test loads, trailer, removable protection and loose spares; actual factory/site/period, supplier boundaries and gate

rule_id	applies_to	rule	source_ids
boundary_construction	all processes	Include actual manufacture, attributable rework, launching and construction commissioning to declared acceptance gate. Allocate independently measured production-support trial resources; exclude recreational boating/transport service and research/operational maintenance. Add every actual tug/dock/crane service or fuel as a separate declared exchange when included, with service boundary/duration and supplier scope. No lifetime voyage burden is inferred.
boundary_modules	purchased components	Count finished fabricated hulls, outboard packages and fitted control/safety modules once with constituents and prefills. Replace constituent cards for included supply. Actual in-house manufacture needs measured component inventories. Complete the full actual BOM, all conditional chemistries and demonstrated species before dataset release; the candidate cards are not an exhaustive vessel bill.

6. Process Inventory Structure

Process Map

process_id	process_name	inclusion	inclusion_condition	role	quantitative_reference
stock_form	Aluminium hull stock cutting/forming	conditional	Stock cutting/forming occurs inside the reporting builder boundary.	foreground	one accepted configured recreational motor vessel, normalized with M
hull_join	Welded hull assembly and completion	required	Each complete welded-aluminium configured boat.	foreground	one accepted configured recreational motor vessel, normalized with M
surface_finish	Conditional hull preparation and coating	conditional	Actual preparation/coating is performed in the reporting foreground.	foreground	one accepted configured recreational motor vessel, normalized with M
rigging	Petrol outboard and steering rigging	required	Each accepted complete petrol-outboard configuration.	foreground	one accepted configured recreational motor vessel, normalized with M
outfit	Deck, electrical and safety outfitting	required	Each complete declared recreation configuration.	foreground	one accepted configured recreational motor vessel, normalized with M
acceptance	Construction commissioning and complete-boat acceptance	required	Each boat released at the declared builder gate.	foreground	one accepted configured recreational motor vessel, normalized with M
packing	Conditional delivery protection	conditional	Actual removable protection supplied at delivery.	foreground	one accepted configured recreational motor vessel, normalized with M

Actual stock forming feeds hull joining and conditional finishing, machinery/outfitting and launch/commissioning/acceptance, then conditional delivery protection. Stages may overlap; assign resources once to actual operations and supplier scope. Every card is conditional on exact composition/state/configuration, even in required stages. Add each actual omitted component/fuel/chemical and demonstrated waste/emission independently. No universal welding/coating recipe or obligatory emission is claimed.

Process: Aluminium hull stock cutting/forming (stock_form)

Cut and form actual certified alloy sheet/plate and structural profiles to serial-linked hull drawings. Record thickness, alloy/temper and actual cutting/forming technology, issues/returns and offcuts. A purchased fabricated hull replaces included stock and fabrication, with its completed operations disclosed. In-house extrusion/casting is not presumed.

7. Allocation and Co-product Handling

rule_id	applies_to	rule	source_ids
allocation_orders	shared shipyard resources	Separate hull orders/configurations and directly attribute measured stock issues/returns, machinery receipts, work hours, meters, trials and rework first. Inseparable shared resources use a demonstrated measured causal driver such as operation time/load or coating area/layer requirement: share = order driver / sum of drivers for all covered orders. Retain period, denominator and causality; tonnage, nominal displacement or equal vessel count is not an automatic causal driver.	ghg-product-allocation-2011
allocation_recovery	internal reuse and waste	Internal reused stock/water/test fuel is a transfer, not repeated fresh input or an automatic credit. Exported waste retains its measured quantity and recipient with no assumed avoided-production benefit. Separate saleable co-products before a documented reviewed residual allocation. Reconcile rejected/reworked construction and work in progress to accepted output during the reporting period.

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
normalize_mass	all inventory rows	q_ref = q_item / M; q_item = exchange amount per one accepted finished unit; q_ref = exchange amount per 1 kg reference flow.	q_item; M; cp_mass	q_ref

For each hull/configuration order collect attributable net stock issues, independent modules, utilities, construction trial consumption, wastes and actual emissions; subtract recorded returns and inventory change and apply justified shared allocation, then divide by accepted vessel count to obtain q_item and by the same controlled measured net M. Preserve physical mass exchanges kg/kg and electricity MJ/kg; independently measured outboard mass establishes configured completeness, never a fixed catalogue engine mass. Compatible serial vessels with measured mass variation may use attributable totals divided by summed accepted net masses, retaining all serial records. Separate incompatible outboard drive, hull, outfitting, coating and trial scope. Unknown is a gap, never zero. No tonnage/capacity/rated-power or lifetime conversion is inferred.

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
quality_mass_origin	cp_mass	The original current vessel acceptance mass record must implement mass_record_provenance. Retain actual physical lightship/weight inspection, observable method inputs/calibration and a signed item-level reconciliation to delivered net configuration; reconcile independently weighed installed modules and fluids. A catalogue or unexplained displacement/tonnage record is insufficient. Missing method, uncertain correction or configuration change prevents a complete quantitative dataset; resolve by new measurement/reconciliation, never an assumed weight.	originals/correction ledger; nma-lightship is a method example only
quality_bom	complete vessel	Reconcile drawings/BOM and installed hull/machinery/outboard drive, piping/electrical, control/safety/navigation and actual service-fluid masses, supplier scope and detached delivered parts. Add all actual missing components before completion; received complete modules count once.	original drawings, weighing and supplier scope
quality_balances	flows and trials	Retain calibration, material issues/returns/reuse, actual formulation/density, commissioning consumed versus retained fuel and measured species/medium/outlets. Define QA limits from applicable actual records or verified comparable evidence; no invented yield, intensity range or universal commissioning consumption.	stock, meters, SDS, trial and transfer records
quality_boat	rigging; outfit; acceptance	Reconcile hull-alloy/temper, actual joints and supplier hull scope; installed outboard/propeller/steering/fuel/electrical/safety components and actual working-fluid masses. Record actual construction trial loads/persons/tanks, speed/load/duration only as measured, calibrated station and engine-test energy/fuel, net returns/recovery/wastes and independently measured exhaust species. Development/model tests are not a mandatory per-boat manufacturing input. Missing net-configuration weight method or correction balance blocks complete quantitative data.	actual drawings, supplier scope, weighing and calibrated trial records
quality_coverage	dataset	Disclose actual geography/period/configurations, conditional absence, outsourcing, identity/quantity uncertainty, empirical range gaps, missing upstream and applicable acceptance regime. Historical manufacturer/authority examples do not prove present certificates, current legal completeness or the actual M of this vessel. PCR checking validates the declared relationship, not a real ship record or scientific approval.	coverage/evidence limitations register

9. Validation Rules

rule_id	applies_to	rule	source_ids
validate_reference	reference	Require complete configured welded-aluminium petrol-outboard recreational motor vessel and positive actual net M from controlled records implementing mass_record_provenance. Exclude operational contents/persons/fuel/fresh water/ballast and temporary loads, retain declared installed service fluids. Reject tonnage, deadweight, catalogue/full-load displacement or full-fuel mass substitution. Missing underlying method or balance requires review and blocks completed quantitative data.
validate_identity	all rows	Check each atomic physical/chemical exchange, public reference property/unit group, route/state and supplier scope. Engine item count is not mass; a complete outboard includes its engine and fitted constituents once; CuO/Cu2O chemical powder is not formulated aluminium-compatible antifouling paint; water supply is not effluent or resource withdrawal. Keep unsupported identity blank and add actual species/components before completion.
validate_measurement	all rows	Verify every amount/collection/conversion against same configuration, actual period/site, accepted count and net M. Reconcile installed prefills, consumed trial fuel and supplier constituents without duplication; verify calibration, density/unit conversions and shared denominator. Unknown is never zero.
validate_species	elementary rows	Use only demonstrated attributable construction-trial species and actual environmental medium. These CO2/NO/NO2 identities are air-unspecified immediate releases; fossil CO2 requires fossil provenance. Total NOx without species split, N2O, nitrogen/nitrite, biogenic CO2, water/soil and long-term releases cannot substitute. Captured dust remains waste.
validate_acceptance	claimed flag/class acceptance	Trace actual vessel-specific surveys/certificates and applicable administration/class regime when claimed. Generic manufacturer certification does not certify this recreational motor vessel; no universal numerical standard/test/load is adopted.

10. Published Dataset Profile

Field	Value
dataset_role	Configured complete welded-aluminium petrol-outboard recreational motor vessel foreground manufacture dataset
downstream_use	secondary_dataset; background_dataset after qualified review and declared upstream linkage
allowed_use	Manufacturing supply-chain models matching hull/outboard drive/outfitting/coating, controlled net-mass scope, trial boundary, gate/site/period
excluded_use	Recreational boating/transport service or lifetime comparison, equal-mass capacity equivalence, other hull/propulsion categories and unsupported complete cradle-to-gate claims
required_metadata	builder/model and hull serial; drawing/BOM revisions; welded aluminium monohull, alloy/temper and supplied hull completeness; installed petrol four-stroke outboard number/serial, mounts/propeller, steering and rigging; actual deck/seat/glass/foam/electrical/safety configuration, coatings and retained working fluids; actual assembly/acceptance criteria and corrected net delivery state; positive M kg from controlled acceptance records with current actual physical weight/lightship inspection, calibrated traceable inputs and signed itemized mass reconciliation; exclude persons, fuel/fresh water/ballast/test loads, trailer, removable protection and loose spares; actual factory/site/period, supplier boundaries and gate
