The bridle itself is a short length
of monofilament line
with a sliding noose in each end.

Begin by tying a noose on the hook
and pulling it up tight
using the knot configuration shown here.

Then tie another sliding noose in the other end
of the monofilament, keeping in mind
that the bridle needs to be quite short,
say 100 mm for towing Skipjack Tuna.

Tying bridles of this short length
does take a little practice.

Close the loop up on your loop gauge or pen,
but not so tight that you can't get it off.

Slide the loop off your loop gauge
and engage your open–eye live baiting needle.

When the baitfish comes aboard, the hook
is usually cut straight off to save time,
and the needle is passed straight through
the eye tunnel of the baitfish taking care
not to damage the eyes.

Pull the second loop right through
and hook it over the point of the hook.

Then disengage the loop
from the open–eyed needle.

The bait is put back in the water
and trolled slowly.
