Overview
SIST EN ISO 11812:2024/A1:2024 is an essential standard amendment for small craft, addressing watertight or quick-draining recesses and cockpits. Developed by CEN and ISO technical committees, this amendment aligns the standard (initially published as EN ISO 11812:2024) with updates and clarifications necessary for craft safety and regulatory compliance. It plays a crucial role in supporting conformity with EU Directive 2013/53/EU, which governs recreational craft and personal watercraft safety within the European market.
The amendment refines definitions, reference documentation, and requirements for drainage, watertightness, and companionway construction. This ensures small craft are designed, constructed, and maintained with enhanced safety standards, particularly concerning flooding risk and water management in critical areas like cockpits and recesses.
Key Topics
-
Updated Terminology and Symbols
Revised definitions provide clarity around terms such as recesses, companionways, retention heights, and more, referencing ISO 12217 and ISO 8666 for design categories and principal data.
-
Watertight and Quick-Draining Recesses
Specifies requirements for ensuring certain areas of small craft prevent ingress of water or allow for quick drainage, using gravity rather than pumps.
-
Companionway Sill and Recess Requirements
Outlines minimum dimensions and configurations for companionways and recesses to reduce flooding risk.
-
Drainage Calculations
Introduces updated methods for assessing draining time, including stepwise guidance for both single and multiple-bottom recesses.
-
Referenced Standards and Harmonization
Aligns with essential harmonized standards such as ISO 8666, ISO 9093, ISO 12216, and the ISO 12217 series, ensuring consistency and up-to-date compliance for small craft.
-
Owner’s Manual Guidelines
Provides instructions for including relevant watertightness and drainage information in the owner’s manual, supporting safe use by end-users.
Applications
SIST EN ISO 11812:2024/A1:2024 applies to all organizations and individuals involved in the design, construction, certification, and maintenance of small craft (boats and recreational vessels up to 24 meters in length). Key practical uses include:
-
Boat Manufacturers and Designers
Ensure cockpit and recess designs meet strict EU safety and construction requirements, supporting market access and product reliability.
-
Certification Bodies and Inspectors
Reference standardized criteria during vessel assessment to confirm conformity with Directive 2013/53/EU.
-
Marine Surveyors
Evaluate vessel features related to watertightness, drainage, and companionway entry points, enabling precise safety checks.
-
Owners and Operators
Gain confidence in the safety of vessel structures and system designs, with guidance available in owner’s manuals for operation and maintenance.
By adhering to this standard, stakeholders contribute to safer boating experiences, minimized flooding risks, and legal compliance in European and international markets.
Related Standards
This amendment refers to and harmonizes with several key international and European small craft standards:
For full compliance and the latest safety information, users should consult these related standards, as well as ensure their craft adheres to the specific clauses referenced in Directive 2013/53/EU as outlined in Annex ZA of the document.
SIST EN ISO 11812:2024/A1:2024 remains central for achieving recognized safety and conformity in the small craft industry, supporting both manufacturers and vessel owners across Europe.
