Planning and Constructing Restricted Water Tracks, Continued
Constructing the In the following table, you’ll find all of the steps listed to construct the
Restricted
restricted water track. This list assumes that all information has been
Water Track
obtained about the port.
Step
Action
1.
Mark all red and yellow soundings.
2.
Lay down intended tracks. Normally, the intended track is laid
down in the middle of the channel (see fig. 12-7). The only
exceptions are very wide channels with mid-channel buoys where
the track is laid in the center of one-half of the channel.
Turn points are normally established by the intersection of two
course lines that have been laid for different legs of the track.
3.
Label all courses, speeds, and distances.
4.
Check for hidden dangers; construct danger bearings if necessary.
5.
Create turn bearings for each turn. Remember to use lighted
NAVAIDs where possible.
6.
Highlight all NAVAIDs and radar points; record in the Standard
Bearing Book.
7.
On several areas of the overall track, display forecasted wind and
current data. This may done by drawing arrows that point in the
direction of wind or current with the force labeled. Alternately,
you may cut out arrows labeled with the information and then use
tape to stick the arrows to the chart.
Note: On larger deep draft vessels, 1 knot of current can equal
about the same as 10 knots of wind. Strong winds along with
1 knot or more of current may make larger vessels crab up a
channel.
