1 Scope

This part of GB/T 19314 specifies the design load and pressure of a multi-hull ship with a hull length of not more than 24 m measured according to GB/T 19916. Determination of force, stress and component size.

This section applies to boats with full displacement and a speed of no more than 50 kn under full conditions. When assessing stability, freeboard and buoyancy, all structures integral components, other high-load areas (eg, ballast keels, mid-water slabs, rudders, chain plates, etc.), usually including watercraft or water all parts of the rain. This section only applies to new boats.

This section does not apply to hydrofoil, small waterplane catamaran and surface effect vessels.
