APPENDIX A Sample Towing Characteristics
Towfish. The Klein Model 5250 stainless steel towfish was used in all cases.
It weighs 48 kg (105 lb) in water, is 16.8 cm (6.6 in.) in diameter and has a
length of 203 cm (79.9 in.). Smaller or larger towfish will only make a
difference when being towed on a cable of less than 60 m (200 ft) length at
speeds slower than 2 knots.
Depressor. The Klein K-Wing II, Model 402A-002 was used to create the
depressive forces in the calculations shown on three of the graphs. The K-Wing
mounts directly to the towfish end.
Interpreting the Graphs. Pick the graph closest to your operating
conditions. With a given speed and cable length, you can determine effective
tow depth. You can also determine the cable length required to reach a specific
depth at a given speed.
More details on towing characteristics, such as tension, layback, etc., are available
at Klein Marine Systems, Inc . We would be glad to help you meet your
requirements. Your experiences in towing our side scan sonar under various
conditions would be helpful in upgrading our data, and we respectfully solicit your
comments.
