Scope: This part of GB/T 20895 specifies the methods for assessing the stability and buoyancy of intact (ie undamaged) boats, including the buoyancy of easily sunk boats. Using this section to assess stability and buoyancy, each boat can be assigned the design category (category C or D) appropriate to its design load and maximum load. This section is mainly applicable to boats propelled by human power or mechanical power with a hull length of less than 6 m, except for habitable multihull sailing boats. For boats with a full deck and a fast-draining stern tank complying with the requirements of GB/T 20896, the hull length is less than 6 m, which can be evaluated according to GB/T 20895.1 or GB/T 20895.2 respectively. In this case, a higher design category can be specified. This Part does not include: - toy boats; - canoes, kayaks or other boats of less than 1.1 m in width; - inflatable boats and rigid inflatable boats not greater than 8 m covered by IS0 6185; - inflatable boats covered by IS0 13590 Personal boats involved; — Hydrofoil craft and hovercraft sailing by means of dynamic support; — Submersibles. This section does not consider or assess the effects of towage, fishing, dredging or lifting operations on stability, such circumstances should be considered separately (if applicable).
