Vessels transiting the Great North East Channel enter or exit the REEFVTS area in three main locations. These are Booby, Bramble or Daru.

　

 It is necessary to state the first and second intended leg for transits through the Great North East Channel. For example, a ship enters at Booby and exits at Bramble, the first leg is via Varzin Passage and the second leg is via West of Coconut Island. This would be communicated to REEFVTS as "GNE, Via Varzin and West of Coconut Island."

　

 In Varzin and Gannet Passages ships are generally restricted by their draught. As a guide, deep draught ships normally transit through the Varzin Passage. Moderate and shallow draught ships normally transit through Gannet Passage.

　

 The standard route plan should be communicated to REEFVTS by stating:

i. GNE Channel

ii. The first set of alternative legs intended to be taken, and

iii. The second set of alternative legs intended to be taken.
