For towing ropes of large diameters, cast closed-loop fodder jams can be used.

Option 1

The tow rope 9, having ogon on the running end, is fed with the root end through the aft lock 6 to the tunnel 12. The tow rope 9 is carried along the tunnel 12 from exit 15 to entrance 13 into it. In this case, the names of output 15 and input 13 of the tunnel 12 characterize their structural affiliation, and not the functional wiring of the tow rope 9.

Next, the towing rope 9 through the guide in the form of a roller 14 is brought out through the cutout 11 in the deck 7 on the drum of the winch 8. The towing rope 9 is mounted on the drum and selected by winding it when the latter rotates.

Option 2

Tow ropes 9, having ogons at the running ends, are fed with the root ends through the feed locks 6 to tunnels 18 and 24. Tow ropes 9 are led through tunnels 18 and 24 from exits 21 and 27 to entrances 19 and 25 in them. In this case, the names of outputs 21 and 27 and inputs 19 and 25 in tunnels 18 and 24 characterize their structural affiliation, and not the functional wiring of the towing rope 9.

Further, the tow ropes 9 are guided in the form of rollers 20 and 26 through cutouts 17 and 23 in deck 7 to the drum of the winch 8. The tow ropes 9 are fixed to the drum and selected by winding it during rotation of the latter.

The winch 8, installed in the stern 5 from the midsection on deck 7, has a control station, which is located close to it for the convenience of monitoring the towed vessel and the equipment for towing ropes 9. The winch 8 is controlled from the navigation bridge.

For the towing cable 9 use domestic winch LBYASH 30/150 or LBYASH 50/150, or LYAB-10, or LBG-40, or other winches of domestic or foreign production.

Instead of a winch when towing, towing hooks of open and closed type (not shown) can be used. To be able to change the direction of the rope, the towing hook can be fixed on an arc, pin or rod. When choosing the installation location of the hook on the vessel, the maneuverability of the towing and towed vessels and the influence of a possible lateral jerk of the towing rope are taken into account.

Towing is a complex operation requiring practical experience, attention and caution from boatmasters of a towing vessel and a towed vessel.

The implementation of the towing cable wiring system 9 with a single-branch line 10 (Option 1) and a two-branch line 16 and 22 (Option 2) extends the functionality of the tow.
