Specifies the structural requirements for fibre-reinforced plastics vessels not exceeding 35 m in length. The requirements for multi-hull vessels are included but the requirements for novel types of vessels such as hovercraft, hydrofoils and small-waterplane-area twin-hull (SWATH) vessels are excluded. Guidance in the avoidance of osmosis in fibre-reinforced plastics vessels is given in an appendix.

This Standard specifies the structural requirements for fibre-reinforced plastics (FRP) vessels not exceeding 35 m in length. It includes multi-hull vessels but excludes novel types of vessels such as hovercraft, hydrofoils and small-waterplane-area twin hull (SWATH) vessels.
