This is the Sea Acceptance Test for the Simrad SC90 Fish finding sonar.
The purpose of this Sea Acceptance Test is to verify the operational
functionality of the SC90 that can only be fully tested with the vessel
at sea. The test assumes that the Harbour Acceptance Test has been
previously done on the same SC90 system. When all the tasks have
been done, the report form must be signed by the relevant parties. The
completed document then becomes the official report.
