The left and right banks of a stream are found by looking downstream. In
drawing this portion of the symbol, attention must be paid to the direction of the stream
flow. Irregular lines are placed on the corresponding side of the basic symbol to show a

1-16. Ferry Symbol. Limited ferry information is recorded on maps or overlays by means
of symbols (STANAG 2253) as shown in Figure 1-17. A question mark is substituted for
unknown or undetermined information.
An arrow extends from the ferry symbol to the geographic location on the
map or overlay. The symbol may be drawn on either side of the stream.
A serial number is assigned to each ferry for later reference. Numbers must
not be duplicated within any one map sheet, overlay, or document. The number is recorded
at the extreme left and above the symbol.
The type of ferry (V or P) is shown after the serial number. If the ferry can
haul vehicles, it can also haul pedestrians.
The MLC of the deck is placed inside the symbol and to the left.
The dead-weight capacity of the ferry (in short tons) is shown inside the
symbol and to the right of the MLC. Dead-weight capacity is the actual load capacity plus
the actual weight of the ferry.
The turnaround time is expressed by the number of minutes required to cross
the water obstacle, unload, and return. Special attention must be paid to the direction of
Left and right banks are determined by looking downstream. Approach
conditions are determined in the same manner as for fords. Irregular lines are placed on
the corresponding side of the basic symbol to show a difficult approach.
