Blowback Calculations
Blowback
Simply stated, blowback is what happens to the
downrigger weight when you pull it through the water
behind your boat. As your speed increases, so does
the horizontal distance between the weight and your
downrigger. The faster you go, the farther the weight is
behind you. The farther the weight is behind you, the
shallower the weight is.
The following charts provide you with blowback in-
formation for three sizes of Cannon downrigger weights
pulled at three different speeds with no lures attached
and with no current. Current drag, water salinity and the
use of non-Cannon products will affect your actual troll-
ing depth.
As an example, the fi rst chart shows that if you are troll-
ing at 4 MPH with an 8 pound weight and you have 100
FT. of cable in the water with no current; the downrigger
ball is actually at a depth of about 80 FT.
