Description of BS EN ISO 12215-7:2020 2020This document defines the dimensions, local design pressures and global loads acting on multihull craft with a hull length (LH) or load line length of up to 24Â m (see Note). It considers all parts of the craft that are assumed watertight or weathertight when assessing stability, freeboard and buoyancy in accordance with ISOÂ 12217 (all parts). Scantlings corresponding to the local design pressures are then assessed using ISOÂ 12215-5. NOTE The load line length is defined in the OMI "International Load Lines Convention 1966/2005", it can be smaller than L H for craft with overhangs. This length also sets up at 24Â m the lower limit of several IMO conventions. This document is applicable to multihulls built from the same materials as in ISOÂ 12215-5, in intact condition, and of the two following types:
It is not applicable to multihull racing craft designed only for professional racing. This document is applicable to the structures supporting windows, portlights, hatches, deadlights and doors. For the complete scantlings of the craft, this document is intended to be used in conjunction with ISOÂ 12215-8 for rudders, ISOÂ 12215-9 for appendages of sailing craft and ISOÂ 12215-10 for rig loads and rig attachment in sailing craft. ISOÂ 12215-6 can be used for additional details. Throughout this document, unless otherwise specified, dimensions are in (m), areas in (m2), masses in (kg), forces in (N), moments in (Nm), Pressures in (kN/m2) (1Â kN/m2Â =Â 1Â kPa), stresses and elastic modulus in (N/mm2) (1Â N/mm2Â =Â 1Â MPa).
