1 Scope

This part of GB/T 19314 specifies the component rule of the rudder mounted on the dinghy of the hull length not exceeding 24 m measured according to ISO 8666.

Inch. This section applies only to individual boats.

This section does not specify the characteristics of the rudder handling capability.

This section only considers the pressure load acting on the rudder due to the manipulation of the boat. Acting on the rudder or rudder post due to stranding or docking (if

The load on the installation) needs to be considered separately.

Note. The component dimensions obtained in this section are mainly applicable to leisure boats, including rental boats.
