GB/T 18815-2013Small craft, engine-driven -- Field of vision from helm position (English PDF)

Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules.

This standard replaces GB/T 18815-2002 "motorized boat steering parts of Vision", compared with the GB/T 18815-2002, the main Technical changes are as follows.

--- Increased "horizontal extent of vision", "sail boat", "sliding state", "taxi boat", "draining the state", "drain the boat" as used herein (see 3.9,3.11,3.12,3.13,3.14 and 3.15);

--- Modify the horizontal range of boats vision requirements (see 512, 2002 edition of 4.1.2.);

--- Changed boat in determining the scope of the horizontal field of view of the vertical reference line hull length (see 521, 2002 edition 4.2.1.);

--- Increasing the vertical position when the steering port and starboard forward field of vision requirements (see 5.2.3).

This standard uses the translation method identical with ISO 11591:2011 "motor boat steering parts of vision" (in English).

1 Scope

This standard specifies the hull length of not more than 24m motor boat steering parts in the forward, backward vision requirements.

This standard does not apply to the following boats.

--- Maximum speed of less than 10kn tiller steering the boat, 3.10;

--- Sail boats, 3.11.

Note. when maneuvering boats sailing in a certain way at a certain speed will cause the pitch angle, in this case, the forward field of vision will be temporarily obscured. This standard in the case of the boat sailing the transition from state to state drainage coasting state and the large pitch angle when sailing, steering parts of the visual field loss is not temporary We do consider.
