CHAPTER 3 Preparation for Use

Remove the retaining ring from the beveled end of the tow pin, withdraw the

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

shackle on the tow depressor tow bracket. 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 towfish 100-inch jumper cable in order

to reach the shackle 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. 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 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.

3.4.4

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 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:
