Overview
EN ISO 14946:2021 (Small craft - Maximum load capacity) defines the items to be included when determining the maximum load of small recreational craft. The standard clarifies seating and occupancy-area requirements, what mass must be counted in maximum load calculations, and the information manufacturers must provide on the builder's plate and in the owner's manual. Personal watercraft are explicitly excluded from the scope.
This edition supersedes EN ISO 14946:2001 and aligns with related ISO standards such as ISO 12217 (stability, buoyancy and flotation) and ISO 8666 (principal data). It also supports conformity to Directive 2013/53/EU where applicable.
Key Topics
- Scope and exclusions: Applies to small craft up to 24 m length of hull; personal watercraft excluded.
- Seat and occupancy definitions:
- Seat minimum dimensions: 400 mm × 750 mm (including clear foot space).
- Occupancy area: clear space within the craft with at least 400 mm × 400 mm per standing person.
- Crew mass assumption: Each person is limited at 75 kg for load calculations (with references to ISO 12217 and ISO 6185 for child allowances).
- Items included in maximum load (Clause 5): The maximum load (m_ML) includes:
- crew mass (75 kg each), personal effects, stores and cargo;
- contents of permanently installed tanks filled to 95 % (fuel, water, oils, live wells);
- ballast water (100 % capacity);
- consumable liquids in portable tanks (95 % capacity);
- dinghies and associated outboards, liferafts beyond the essential minimum, and additional non-standard equipment.
- Manufacturer’s values:
- Maximum recommended load: determined in accordance with stability, freeboard, buoyancy and flotation requirements.
- Builder’s plate load (m_B_P): displayed load that excludes the weight of contents of fixed tanks when full (per Clause 7).
- Owner's manual requirements: Manufacturer must state the maximum recommended number of persons and the builder’s plate maximum load.
Applications
This standard is essential for:
- Boat designers and builders calculating safe load limits and producing compliant builder’s plates.
- Certification bodies and conformity assessment tied to maritime safety directives.
- Owners and operators who need clear guidance in the owner’s manual for safe loading, seating and occupancy.
Practical benefits include consistent load accounting across small craft, clear seating/occupancy rules, and harmonized information for regulatory compliance and safe operation.
Related Standards
- ISO 12217 (all parts) - Stability and buoyancy assessment and categorization
- ISO 8666:2020 - Small craft principal data
- ISO 6185 (all parts) - Inflatable boats
For design validation always refer to the normative clauses of EN ISO 14946:2021 together with ISO 12217 and ISO 8666. Consult the owner’s manual and builder’s plate for the manufacturer’s specified limits before operation.
