GB/T 18822.2-2024 in English

The standard GB/T 18822.2-2024, titled "Small Craft - Determination of Maximum Propulsion Rating by Maneuvering Speed - Part 2: Craft with Hull Length Between 8m and 24m," is a technical specification issued by the Standardization Administration of China. It provides guidelines for determining the maximum propulsion power rating for small craft based on their maneuvering speed, specifically for vessels with hull lengths ranging from 8 meters to 24 meters. This standard is applicable to recreational and commercial small craft, ensuring safety, performance, and environmental compliance.

The standard outlines the methodology for calculating the maximum propulsion power by considering factors such as hull design, speed, and operational conditions. It aims to establish a uniform approach to power rating determination, which is crucial for manufacturers, regulators, and operators. By adhering to this standard, stakeholders can ensure that small craft are designed and operated within safe and efficient power limits, reducing risks associated with over-powering or under-powering.

GB/T 18822.2-2024 is part of a series of standards addressing small craft propulsion ratings, with this part focusing on medium-sized vessels. It complements other standards in the series, providing a comprehensive framework for the industry. The standard was released on April 25, 2024, and will come into effect on May 1, 2025, marking an important step in the standardization of small craft design and operation in China.
