Full title and description

ISO 11812:2020/Amd 1:2024 — Small craft — Watertight or quick‑draining recesses and cockpits — Amendment 1. This document is an amendment to ISO 11812:2020 introducing changes and clarifications to the original second edition (2020) requirements for watertightness, draining performance and sill heights of recesses and cockpits on small craft.

Abstract

This amendment updates ISO 11812:2020 (Edition 2) which specifies requirements for watertightness, draining time and sill heights for watertight or quick‑draining recesses and cockpits in small craft (typically up to 24 m load line length). The original standard addresses draining by gravity only and clarifies its relationship to stability and buoyancy standards.

General information

• Status: Published
• Publication date: 8 August 2024
• Publisher: International Organization for Standardization (ISO)
• ICS / categories: 47.080 (Small craft)
• Edition / version: Edition 2 (2020) — Amendment 1 (2024)
• Number of pages: 10 (amendment document)

Scope

The amendment applies to ISO 11812:2020 and covers requirements and clarifications for watertight and quick‑draining recesses and cockpits on small craft (generally up to 24 m load line length). The standard addresses draining by gravity (not by pumping) and does not specify recess/cockpit size, shape or exact placement; it also does not replace separate stability and buoyancy requirements found in ISO 12217 series.

Key topics and requirements

• Watertightness criteria for recesses and cockpits.
• Draining performance: maximum draining times and quick‑draining requirements (gravity draining only).
• Sill heights and related dimensional requirements to limit water ingress.
• Applicability to small craft up to 24 m load line length and exclusion of pumping as a draining method.
• Clarifications to align with stability and buoyancy standards (ISO 12217 series) and to correct or refine technical/editorial points from the 2020 edition.

Typical use and users

Designers and naval architects of small craft, boatbuilders, classification societies, maritime safety authorities, conformity assessment bodies, surveyors and product certification organizations use this amendment together with ISO 11812:2020 to ensure recesses and cockpits meet watertight/draining performance expectations and regulatory or class requirements.

Related standards

Closely related documents include ISO 11812:2020 (the base standard), the ISO 12217 series (stability and buoyancy for small craft), and hull construction and structural design standards such as ISO 12215. These documents are typically used together when assessing overall safety and seaworthiness of small craft.
