ISO 12215-5:2019 PDF Download

ISO 12215-5:2019 is a standard that provides guidelines for the design pressures, design stresses, and scantlings determination for the hull construction of small monohull watercraft of up to 24m in length. The document takes into consideration all parts of the craft that are watertight or weathertight to assess stability, buoyancy, and freeboard according to ISO 12217. This standard includes the assessment of structures supporting windows, portlights, hatches, deadlights, and doors. It can be used for both recreational and small commercial craft and workboats while excluding racing craft designed only for professional racing. The standard is not applicable to traditional wood construction.

The core of the document determines the local design pressures and stresses for monohulls and presents various scantling methods derived from these parameters for both monohulls and multihulls. The assessment process is aided by several annexes for relevant applications. Local pressures and stresses for multihulls are given in ISO 12215-7. To obtain complete scantlings of the craft, this standard should be used in conjunction with ISO 12215-8 for rudders, ISO 12215-9 for appendages and ISO 12215-10 for rig loads and rig attachments. The document is applicable to craft constructed from fibre-reinforced plastics, steel or aluminum alloys, glued wood or plywood construction, excluding traditional wood construction.
