BS EN ISO 12217-3:2025

This standard BS EN ISO 12217-3:2025 Small craft. Stability and buoyancy assessment and categorization is classified in these ICS categories:

• 47.080 Small craft

This document specifies methods for evaluating the stability and buoyancy of intact (i.e. undamaged) boats. The flotation characteristics of craft 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 (C or D) appropriate to its design and maximum load. This document is applicable to boats of hull length less than 6 m, whether propelled by human or mechanical power, except habitable sailing multihulls. Boats of hull length less than 6 m which are fitted with a full deck and quick-draining cockpit(s) complying with ISO 11812 can alternatively be assessed using ISO 12217?1 or ISO 12217?2 (for non-sailing and sailing boats, respectively), in which case higher design categories can be assigned. 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; —     aquatic toys; —    canoes and kayaks; —    gondolas and pedalos; —    sailing surfboards; —    surfboards, including powered surfboards; —    hydrofoils, foil stabilized boats 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.
