CHAPTER 3 Setup and Test
Remove the retaining ring from the beveled end of the tow pin, withdraw the
1.
pin from the tow bracket and set it aside. Remove the two bolts and tow
brackets from the welded-on six-hole towing flange. Take note of the location
of the tow brackets for future reference.
2. Position the K-Wing depressor over the towing flange in the same location as
where the tow brackets were previously connected. Secure the depressor to the
towing flange with the fasteners provided.
3. Align the tow shackle mounting hole with the mounting hole of the K-Wing®
depressor tow bracket, with the shackle pigtail connector facing the tail of the
towfish. Insert the beveled end of the tow pin through the holes in the tow cable
shackle and the bracket, and secure the tow pin with the retaining ring.
4. If the towfish was previously configured for towing without a depressor, it will be
necessary to extend the free length of the tow cable jumper in order to reach the
shackle pigtail connector. Do not extend more than is needed to make the
connection and to provide free rotation of the tow shackle. Remove the dummy
plug from the connector on the end of the tow cable. Apply a thin film of silicone
grease to the pins of the connector. Do not over grease. Align the male and female
connectors, and press the connectors together firmly. If necessary, use a slight
side-to-side rocking motion while pressing on the connector, but do not bend the
pins. When properly inserted there should be no gap between the surfaces of the
two connectors.
5. If using a safety cable, attach the shackle end of the safety cable to the bail grip
loop on the tow cable near the tow cable shackle. Attach the strap fork with clevis
pin end to the safety cable tab on the top of the towfish near the tail.
6. If using a safety cable, and if it is not already secured, use cable ties
(7.5 x 0.185 in.), which are included in the towfish spares kit, to fasten the safety
cable to the cable hold-down clips on the top of the towfish housing. Place a cable
tie through the shackle pin hole and wrap around the shackle pin to prevent the
shackle from loosening. Use electrical tape every 30 cm (12 in.) to secure the
safety cable to the tow cable starting at the top of the tow shackle and up the bail
grip loop. Move the tow shackle forward and back to check for smooth operation.
3.5.4
If possible, it is best to keep the tow cable connected to the towfish while on deck.
If the tow cable is disconnected, however, it is very important that all connectors
be properly maintained. Connectors must be kept clean and must remain out of the
way of traffic while on deck. Klein Marine Systems, Inc. supplies dummy
connectors which can be used to protect the underwater connectors on the towfish
and cable when they are not mated to each other. The procedure for disconnecting
the tow cable from the towfish is as follows:
