Practice Maneuvers

1. Make a hard-over turn in deep water and use the wake to measure the ship's- táctica! diameter. A brightly painted oil drum can be used as a reference or

the diameter can bè measured by radar using the display óf the sea returngenerated by the ship's wake. Hòw^âbea the diameter of the turning circlecompare with the ship's length?

Make the same^turn in shallow water £a depth less,than 1.25 times draft)and measure the turning circle. How does the.diam.eterof the turning circle inshallow water compare with that observed in.deep water?

2. Your ship is dead in the water. Put the rudder hard-oyer and put the engineprogressively from slów, to half, and then to full aheád só the ship executes acomplete circle with the revolutions increasing through. the entire 360 de-grees. Use the wake as in maneuver l above, to measure the diameter of thisturn. Now, leave the engine on full ahead and again measure the turning cir-cle diameter while making another complete 360-degree turn with the enginespeed unchanged (a steady state turn). How does the diameter of the acceler-ating turn compare with that of the steady state turn?

3. Perform the master's mane.uue.rs described in chapter l while one of the ship'smates collects data on your ship's characteristics using a data sheet similar tofigure 1-2 on page 9. Analyze these data and compare the rate of turn, time tostop, change of heading when stopping and backing, and other importantcharacteristics with the data collected aboard other ships you have maneu-vered. Study ali the pertinent information só you have some feel for your shipand can predict her behavior with reasonable accuracy.

4. This exercise will give you a feel for, and appreciation of, using hard-over rud-der to reduce speed. First, measure your ship's speed approaching an open an-chorage or pilot station. This can be done with a Doppler log, or the ship'sARPA (plotting a fixed point while the ship's speed is manually input to Oknots só the "computed speed" of the fixed object is then your ship's speed), orby any other method you might choose. A series of simple fixes at frequent in-tervals can be used to at least get a rough measure of speed and changes inspeed. Obviously, you can't accurately determine absolute speed with the lat-ter method, but changes in speed will be quite apparent to the experiencedmariner and this exercise can still be very useful even if your ship isn't fittedwith equipment to measure speed accurately.

Put the rudder hard over and change the ship's heading by at least 45 de-grees. Measure the ship's speed again and calculate the reduction in speed.Repeatedly shift the rudder from hard over to hard over while continuing tomeasure or estimate speed through the water and changes in speed until theship's headway is significantly reduced.

5. When searoom permits, make a practice of putting the rudder hard over to-ward the lee side (toward the side on which a pilot is boarding) a short time be-fore the pilot begins boarding. Observe how this sweeps a smooth lee for thepilot and makes boarding quicker and safer.

2. Make use of every opportunity to practicé hàndling your ship at minimumspeed. Stop the engine and keep her on course while approaching an anchor-age or pilot station, using hard-over rudder as headway is lost. Be patient,watch the stem or jackstaff closèly to detect movement às sòõn as possible,and learn how slowly your ship can be handled. When she no longer answersto rudder alone, use short kicks on the engine to start and check swing, andpracticé until you can handle your ship at less than l knot in ali but the worstconditions with a minimum of engine maneuvers. Anyone can handle a shipat sea speed!

.*3. Look over the side and check the position of the quickwater every time you

back the engine to slow or stop your vessel. Use the location of the quickwaterto estimate headway when approaching an anchorage, berth, or pilot station.(Read pages 119—120 for approximate speeds vs. quickwater position.)

4. If your ship is fitted with a Doppler log, check your speed through the waterwhen the quickwater is moving forward at the same speed as your ship, whenthe quickwater starts moving forward along the ship's hull, and when thequickwater reaches amidships.

Slack more chain, as necessary, un-til the drag of the anchor begins reducing the ship's headway (a lengthof chain equal to approximately twice the depth of water). Note howthe ship is steadied by the anchor as compared to maneuver Ia above

and thai there is no immediate or violent change in the ship's headingwhen the ancfaor is used.

c. Come dead slow or slow ahead and use the ship's rudder to maintainthe ship's heading across the wind. Slack out more chain if necessarysó the ship remains dead in the water at low RPM and note how theship's heading and position can be maintained, even when lying acrossthe wind.

d. Increase revolutions until the ship begins moving ahead again and usethe rudder to maintain the selected heading aeross the wind. Increaseand reduce revolutions to increase and décrease the ship's headway.Observe the ship's behavior under control of the anchor, including thechange of headway when engine EPM is changed; the time requiredfor the ship to lose ali headway when the engine is stopped; and speedthrough the water at a giyen RPM with the anchor on the bottom, ascompared to the speed at the same RPM without the anchor.

e. Reduce to dead slow ahead, and when the ship is dead in the water, usethe rudder'to change heading to port and starboard. Note the effect ofrudder on rate of turn and how quickly the ship steadies up with therudder amidships. Also pay attention to the forwárd shift of the pivotpoint toward the bow; the reduced diamètêr ôf the ship's turning cir-cíe; and leeway, or, more accurátely, the lack of leeway as the ship isheld on a particular heading.

f. Increase and décrease RPM and again alter the ship's heading, thistime with headway. Note that it's possible to make very controlled ma-neuvers by coming ahead on a fixed heading to move the bow toward adesired point, and by reducing RPMs until headway is lost and thenusingthe rudder to move the stern to one side or the other, ás might bedone to come alongside a berth.

Ali this should help you develop an understanding of, and a feel for,shiphandling under the control of an anchor. Think how useful maneuver Icwould be while holding a ship awaiting tugs or improved weather conditions.Ship behavior demonstrated in Id would be useful in very narrow channels orin reducing speed without backing (or when youVe lost the engine) while thepractice in lê becomes important when you have to maneuver in a narrowchannel or into a narrow berth without a tug (by choice or circumstances), orneed the anchor to break a sudden sheer while proceeding up the channelfrom sea. Maneuver If puts it ali together and shows how a ship can make con-trolled maneuvers or come alongside a berth or another vessel under perfectcontrol, using an anchor even when conditions are less than ideal.

2. Hold your ship in position using the anchor and a short scope of chain whilewaiting for the pilot to board. This maneuver is most advantageous with alight ship in bad weather and you should try it at every opportunity to gain ex-perience in ali conditions of wind, tide, and ship's draft.

a. Reduce speed to bare steerageway and put down one or two shots ofchain (depending on the depth of water). Steam on the anchor, adjusting

the rudder angle and engine revolutions to head the ship into the pre-vailing wind and sea.

b. Adjust RPM and slack a bit more chain, if necessary, and continuecoming ahead against the anchor. Hold the ship stationary relative tothe bottom on the same heading into the prevaíling wind and sea.

c. Put the rudder hard over as the pilot boat approaches and increase en-gine RPM to change heading across the wind and sea/swell and make alee for the pilot. Depending on cireumstances, you could begin heavingthe anchor after the pilot boards or steam on the anchor to bring theship around to the initial course toward the channel while awaitingthe pilofs arrival on the bridge.

This is certainly a lot safer and easier than backing and filling for half anhour in a crowded anchorage while awaiting the pilot launch!

••--. : . . . Practice Maneuvers

The Williamson Turn is used for man-overboard emergências and for routine vesselmaneuvers, both to bring a ship back to a desired point with a minimum of maneu-vering and to help mates and masters appreciate a ship's handling characteristicsat full speed at sea. Turning circles, the time and amount pf rudder needed to makeand check tums, and the amount of speed a ship losés making large course changescan ali be demonstrated during a Williamson Turn. :-.

1. Paint an oil drum or other object bright orange só it can be easily seen andused as a reference during the Williamson Turn. Puncture both ends of a5-gallon paint pail and attach it to the drum with small diameter line. Thepail serves as a drogue to minimize wind drift during the exercise. Also, pre-pare a data sheet, like the one described in ehapter l for the master's maneu-vers, to collect data during the maneuvers. The information will be usefulwhen studying the ship's performance and comparing handling characteris-tics under different conditions of loading.

2. Muster the crew prior to starting the Williamson Turn, and explain the ma-neuver and its purpose as both a man-overboard drill and a shiphandling ex-ercise. The details of the man-overboard procedure are outside the scope ofthis book, só only the shiphandling aspecís of the maneuver will be discussedhere.

3. Throw the drum or reference object over the side, note the ship's base course,put the rudder hard over, and start the turn as described on page 232. Mea-sure the time required for the ship to begin turning after the rudder is puthard over and compare the advance and tactical diameter with the ship'slength, as the ship turns, using the drum as a reference. This information willbe helpful both for maneuvering in close quarters situations at sea and in any

Page 28: Questões SHFM

future emergency situation that might arise. The time to turn, the tactical di-ameter, and the advance will probably be significantly less than you expected.

4. Continue the maneuver, shifting the helm from hard over to hard over whenthe heading hás changed 55 degrees from the base course (point "A" in figure9-15). Note the heading when the ship steadies up and begins swinging in theopposite direction. Calculate the number of degrees that the ship swings be-fore she checks up and you'll know the are of swing required to steady up froma hard-oyer turn.

5. Keep the rudder hard over as the ship turns through a cirçle toward the recip-rocai of her initial heading. Apply the are required to check her swing, as cal-culated in maneuver 2 above, and when the ship's heading is that number ofdegrees from the desired final heading (the reciprocai of the initial heading),reverse the rudder hard over again. The ship should check up on, or near, thefinal heading as" the ship returns to her starting point alongsidè the referenceoil drum.

The ship will have completed the Williamson Turn in a predictable manner withthe least possible helm movements (three) and thus thi minimum of variables.Note the total time to complete the maneuver, the speed through the water at theend of the maneuver, and the distance and bearing from the starting point. If de-sired, back down and stop the ship as close to the starting point as possible.

6. Perform the maneuver again using an initial change of heading at point "A" of35 degrees. Did your ship return closer to or farther from her starting pointusing this smaller initial course change? The required initial change of head-ing is, to a large extent, determined by the ship's directional stability, and themore positive the directional stability, the farther the ship should be allowedto swing before shifting the helm at "A."

Practice this maneuver at light and loaded drafts, in various conditions oftrim, and let ali the ship's officers perform Williamson Turns só everyonelearns the procedure. A great deal can be learned about shiphandling param-eters and the effects of various loading and trim conditions by eomparing theturning rate, most effective change of heading at point "A," tactical diameter,advance, etc.

ABOUT THE AUTHORS

Daniel H. MacElrevey was raised near the Delaware River where he de-veloped an interest in the sea watching the ships come and go from theport of Philadelphia. He graduated from the U.S. Merchant Marine Acad-emy in 1963 and went to sea as a deck officer with Moore-McCormackLines aboard cargo and passenger ships trading to South and East África,South America, and northern Europe. He also worked with the same com-pany in marine ope*ations and stevedoring in New York. ...

He and his family moved to Panamá in 1970 where he worked as a Pan-amá Canal pilot for eight years. Living in Panamá provided the opportu-nity for him to pursue another strong interest—ocean sailing—and laterhe and his family lived aboard and cruised before he returned to sea. Hesubsequently spent four years as master of LNG vessels with El Paso Ma-rine Company and served as mooring master for VLCCs at the LouisianaOffshore Oil Port. •: .J/-.:'::.•;..-;-.:

Captain MacElrevey resumed a career in Panamá and spent morethan 24 years piloting ships in the Canal and the ports of Balboa áhdCristobal. He hás also become very involved in the use of simulation forshiphandling training and evaluation including service as a member ofthe Committee on Ship Bridge Simulation Training sponsored by the Na-tional Academy of Science's Marine Board in 1993—95. He was chairmanof the Panamá Canal Pilot Association's technical committee while work-ing on studies of ship behavior and squat in narrow channels with Water-way Simulation Technology, Inc. and developing a real-time vessel trafficand Communications system for pilots (CTANS) with the Department ofTransportation's Volpe Center. Captain MacElrevey retired from his posi-tion as pilot and port captain at the Panamá Canal in 1998.

MacElrevey provides consulting, training, technical writing, and ship-handling services to the marine industry through Offshore Services Com-pany, which he formed in 1980. Current work includes services asconsultant and expert witness for various maritime law firms and simula-tor-based training for pilots and ship's officers including a contract at the

Daniel E. MacElrevey celebrated his second birthday aboard the S.S.Cristobal, while enroute to Panamá. His early childhood was spent livingnear the locks of the Panamá Canal and it was there that he developed hisfondness for ships and appreciation for the mariners who guide them. Hemade his first transit of the Panamá Canal with his father at age eight.Following this trip he declared his intention to one day be a pilot.

Dan's family left Panamá in 1977, living aboard their boat for a year-before settling in Cape May, New Jersey. Dan developed his love of life onthe water during subsequent summers spent saiHng on the waters of theDelaware and Chesapeake Bays, and racing small boats in New Jersey.

He graduated from the U. S. Merchant Marine Àcademy in 1990 andwent to sea with Mormac Marine Transport as a deck officer aboard tank-ers engaged in the charter trade. During his time as deck officer withMormac, he traveled to many ports on both coasts of the United States, toCanada, to South and Central America, the Caribbean, Europe, northern-Africa, partsof Ásia, and the Mediterranean.

In 1994, Mr. MacElrevey began a three-year apprentice program withthe Pilot's Association for the Bay and River Delaware. In addition toniaking trips with experienced pilots, his training included simulator-

^htsed classes at MITAGS in Maryland and at the STAR Cènter in Florida,and manned-model instruction at the Sóuthampton Institute in England.He is now a first-class pilot handling ships in the Deljiware Bay and River,guiding ships through the Chesapeake and Delaware Canal, and dockingships at bsfths"in Salem, New Jersey.

Dan was first involved with Shiphandling for the Mariner as a teen-ager, checking- for spelling mistakes by reading sentences from the textbackwards, and he is tremendously honored to have worked with his fa-ther on this fourth edition. Ships and equipment evolved during the pasttwenty years, but the text remains current because shiphandlers sharetheir specialized skills with their peers. Dan hopes.those whp read this lat-est edition will continue that tradition.

Daniel E. MacElrevey lives in one of the oldest pilot towns in theUnited States—Lewes, Delaware—with his wife, Dana, and their twochildren, Austin and Madison. Their home is a short distance from the pi-lot station at the entrance to the Delaware Bay. A love of the sea and thepractice of shiphandling have passed to the nsst generation.
