A light wire fitted with sister hooks is handy for this purpose and should be given a lead close to the pelican hook slip.ġ1. The sweep wire is then hauled through kite ring and fair-leads to the slip, in which it is directly secured. (b) If the shearing pin coupling and pendant are not used, lead a receiving line from a winch gypsy through fair-leads and kite ring ready to bend on the end of the sweep wire when received. At that point the sweep wire is to be joined to the shearing pin coupling and the pendant and the coupling then thrown clear astern. (a) Secure the end of the shearing pin pendant in the pelican hook slip and reeve it through all fair leads, kite ring, and back to a point at the rail convenient for receiving the end of the sweep wire from the winch boat. (c) Pair off with the slip boat designated and take position 100 yards astern of her, ready for coming alongside and passing the sweep.ġ0. (a) Provide sweep buoys and means of attaching them to the sweep wire in case they are to be used. Enough slack is stopped up along the rail to reach the slip boat, which has to haul the end aboard and secure it. (a) Unreel sufficient sweep wire to reeve it off through all fair leads and kite ring and thence to a point at the rail convenient for passing the end by means of heaving lines to the slip boat. (5) Take position preparatory to passing the sweep.ĩ. Preparations on both boats for sweeping. The winch boat uses her sweep wire for the sweeping, passing it over to the slip boat, which secures the end of it on board ready for slipping.Ĩ. The two boats of a sweeping pair are called the winch boat and slip boat, respectively, though the term is temporary only, as any sweeper may be assigned to either duty and must be prepared to act in either capacity at any time.ħ. GENERAL DESCRIPTION OF PASSING THE SWEEP.Ħ. Buoys attached to the bight by pendants are used for this purpose. When sweeping over a rocky bottom it is frequently necessary to hold the bight of the sweep wire up to a certain depth as well as to hold its ends down to this depth. A depth of 6 fathoms for the kite is desirable and is usually obtained under standard conditions, with 11 fathoms of kite wire out, at not above 10 knots.ĥ. The depth of the kite depends on the length of kite wire out the speed through the water, and the tension on the sweep wire. The limits of the swept channel may be taken safely as being 50 yards inside the wake of each sweeper.Ĥ b. A ring on the end of a short pendant attached to this water kite acts as a fair lead for the sweep wire, which, from there to the opposite kite, sweeps wholly at or below the depth of the kite, thus sweeping the fall width of channel between the kites at their depth. A water kite dives to a certain depth in a water current just as an ordinary kite rides to a certain height in an air current. A device known as a water kite is therefore towed by each sweeper to force its respective end of the sweep wire down to the desired sweeping depth. To obtain this certainty is the main object of sweeping operations.Ĥ a.
