GB/T 19314.6-2019 is the English-translated version of 小艇艇体结构和构件尺寸第6部分：结构布置和细则.

GB/T 19314.6-2019 is the Chinese standard "Small craft -- Hull construction and scantlings -- Part 6: Structural arrangements and details". Its scope clause reads: This part of GB/T 19314 relates to GB/T 19314.5-2019, ISO 12215-7, ISO 12215-8 and ISO 12215-9.

Clear structural details and structural elements. This section applies to fibre reinforcements with a hull length of not more than 24 m in accordance with ISO 8666 Monolithic and multi-hull boats constructed of plastic (FRP), aluminum or steel alloys, wood or other hull materials.

This section includes two features. First, provide an explanation of the further calculation process and formula for GB/T 19314.5-2019; Second, provide examples of structural arrangements and rules for applying the principles.

The structural arrangements and details specified in this section can be used as a design basis. Note. This part of the component size is mainly used in yachts, including rental boats, excluding rowing. Its clauses include terms and definitions.
