4.2.6.1.2 Depressor Operation
Using the tow fish with the depressor wing will require some changes from the normal methods of
operation. The load applied by the depressor wing is speed dependent. As the tow speed is
increased the pull force is increased. This does not mean that the faster you go the deeper you can
operate the tow fish. The drag force that causes the fish to lift up will also increase with speed.
This increased drag force will reduce the effective weight that the depressor wing adds to the cable.
The depressor wing is most effective with speeds ranging from 2 to 4 knots.
WARNING:
The depressor wing is capable of applying over 100lbs of force on the cable. To ensure
safe operation please read over and abide by the following precautions:
·
Inspect all tow cable strain reliefs for proper attachment and wear and replace as necessary.
·
Inspect the boat strain relief attachment line for wear and ensure that it is adequately rated.
