Vessel Operation
For increased holding power in windy conditions, two anchors are
sometimes set. If your primary anchor drags, you can run out your
secondary anchor without picking up the primary one. The important
thing is to lay them out at an angle. When setting two anchors, make
sure they are fastened to separate rodes or cleats. This is done in case
you need to adjust one later so the line is accessible.
If two anchors are used ahead of a boat, make sure to set the rodes at
an angle rather than in a straight line to reduce the chances of tangling
as the boat moves in wind and current.
