8.7 Target intercept
The Intercept feature can be used to help rendezvous with friends or for Pilot boats and the
Coastguard to intercept vessels that are to be boarded.
To use the Intercept feature, select and hold the target icon until the menu is displayed,
then select Intercept . The Chart app will automatically plot a direct course to a point
where your vessel and the target will cross (intercept).
An interception mark is placed at a predicted point where both your vessel and the
target will cross.
Important:
When performing an individual interception, you are placing your vessel on a collision
course with the target vessel. It WILL be necessary to change to a parallel course to
prevent a collision.
Pre-requisites:
• It is vital to have a good understanding of the International Regulations for Preventing Collisions at
Sea (IRPCS / COLREGS), to ensure all actions taken are in accordance with the IRPCS. For more
information on IRPCS / COLREGS, refer to: IRPCS
• You must be familiar with the AIS feature.
• You must have a thorough understanding of the Target interception feature and its implications
before attempting to use it in a real life scenario.
