8.12 SAR (Search and Rescue) patterns
Attempting to search the water for an object can be challenging, due to the vastness of the ocean
and the effects of tide. Additionally, the object you are searching for is not normally in its last
known location.
SAR Patterns are routes that can help you find an object in the water. The pattern can be modified
and can take the effects of the tide into account, providing a more accurate and consistent route to
search. SAR Patterns can be created on your MFD in the
Chart app .
Access search pattern options: Chart app > Menu > New > Search patterns .
The available Search Patterns are:
• Sector Search
• Expanding square
• Creeping line
• Parallel Line
Once a search pattern is created it is saved as a Route and can be managed and navigated in the
same manner as any other saved Route. For more information refer to:
7.2 Routes
When the MFD is configured using the ‘First responder’ boating activity profile SAR patterns can be
received over STEDS messaging. For more information refer to:
9.8 SAR pattern receipt
Sector search pattern
The Sector Search pattern is made up of 9 legs, with the 3rd, 6th and 9th leg running past the datum
(the Track Spacing will change depending on whether you are with or against the drift).
Note: As the Search patterns take in to account drift, the resulting Route may not resemble the
patterns shown.
