ISO 12217-1:2022

Small craft — Stability and buoyancy assessment and categorization — Part 1: Non-sailing boats of hull length greater than or equal to 6 m

Edition date: 2022-12-16
In Force
Available languages: French, English
Summary:

This document specifies methods for evaluating the stability and buoyancy of intact (i.e. undamaged) boats. The flotation characteristics of boats susceptible to swamping are also encompassed.

The evaluation of stability and buoyancy properties using this document will enable the boat to be assigned to a design category (A, B, C or D) appropriate to its design and maximum total load.

This document is principally applicable to boats propelled by human or mechanical power of 6 m up to 24 m hull length. However, it can also be applied to boats of under 6 m if they do not attain the desired design category specified in ISO 12217‑3 and they are decked and have quick-draining recesses which comply with ISO 11812.

In relation to habitable multihulls, this document includes assessment of susceptibility to inversion, definition of viable means of escape and requirements for inverted flotation.

This document excludes:

—    inflatable and rigid-inflatable boats covered by the ISO 6185 series, except for references made in the ISO 6185 series to specific clauses of the ISO 12217 series;

—    personal watercraft covered by ISO 13590 and other similar powered craft;

—    gondolas and pedalos;

—    sailing surfboards;

—    surfboards, including powered surfboards;

—    hydrofoils and hovercraft when not operating in the displacement mode; and

—    submersibles.

NOTE       Displacement mode means that the boat is only supported by hydrostatic forces.

It does not include or evaluate the effects on stability of towing, fishing, dredging or lifting operations, which need to be separately considered if appropriate.



Le présent document spécifie les méthodes d'évaluation de la stabilité et de la flottabilité des bateaux à l'état intact (c'est-à-dire non endommagés). Les caractéristiques de flottabilité des bateaux susceptibles d'envahissement sont également prises en compte.

L'évaluation des propriétés de stabilité et de flottabilité effectuée en utilisant le présent document permettra d'attribuer à un bateau une catégorie de conception (A, B, C ou D) appropriée à sa conception et à sa charge maximale.

Le présent document est principalement applicable aux bateaux propulsés par l'énergie humaine ou mécanique, d'une longueur de coque comprise entre 6 m et 24 m. Elle peut, cependant, être également appliquée aux bateaux de moins de 6 m, s'ils n'atteignent pas la catégorie de conception désirée en appliquant l'ISO 12217-3, et s'ils sont pontés et munis de cavités rapidement autovideuses conformes à l'ISO 11812.

Pour ce qui concerne les multicoques habitables, le présent document comprend l'évaluation de la susceptibilité à l'inversion, la définition d'un moyen d'échappée viable et les exigences de flottabilité à l'état inversé.

Le présent document exclut:

—    les bateaux pneumatiques et semi-rigides couverts par la série ISO 6185, excepté lorsque la série ISO 6185 fait référence à des paragraphes spécifiques de la série ISO 12217;

—    les véhicules nautiques à moteur (motos aquatiques), couverts par l'ISO 13590 et engins à moteur similaires;

—    les gondoles et pédalos;

—    les planches à voiles;

—    les planches de surf, y compris les planches de surf motorisées;

—    les hydrofoils et les bateaux à coussins d'air (hovercraft) lorsqu'ils ne fonctionnent pas en mode à déplacement; et

—    les submersibles.

NOTE            Le mode à déplacement signifie que le bateau est uniquement supporté par des forces hydrostatiques.

Il n'inclut ni n'évalue les effets sur la stabilité provenant du remorquage, de la pêche, du dragage ou d'opérations de levage, qui doivent être, si nécessaire, considérés séparément.
