Trinovante must have sufficient ‘way on’ to be able to tack.
This means it must be moving through the water at the best speed for the conditions and be at the right angle to the wind neither too close nor too far off.
The staysail lizard or backing line (red) is secured.
The crew are in position – No.1 to cast off the staysail lizard, No.2 to cast off the port jib sheet (mauve) No.3 on the helm and No.4 ready to sheet in the jib on the starboard side.
Any topsails will have been been lowered prior to tacking.
‘Stand by to tack’ calls the crew to their positions. ‘Ready about’ means tacking is imminent
