Safety At Sea Studies - Lifesling® Clinic
|
INTRODUCTION This manual is designed to enable a skilled sailor to teach the use of the Lifesling®. The Sailing Foundation, which has developed this system, has found that a lecture format followed by on-the-water instruction is the most effective way to teach the use of the Lifesling®. The Sailing Foundation has accomplished successful retrievals in sail and power vessels in wind conditions up to 35 knots of wind. It is important to note that sailors who are not to accomplish basic tasks of tacking, gybing, raising and lowering sails are not likely to be successful at Crew Overboard (COB) retrieval. For students who can accomplish these basic tasks, The Sailing Foundation methods have proven to be successful. The Sailing Foundation method focuses on the most difficult COB situation, specifically that of a two person crew with one overboard which necessitates a single-handed pickup in fresh wind and sea conditions exacerbated by cold water commonly present in northern waters. The method is also effective when used by more than the single-handed crew. It is successful when used students with a large variety of boats and wind conditions. An instructor should be thoroughly familiarize him/herself with the history of the Lifesling® including the case histories as well as other recommended methods commonly found in published material. Most other methods have not been tested, few of them work, and in fact may be dangerous. It is important to be aware that students may come to the clinic with preconceived ideas about COB retrieval, which may include those other methods. The teacher should be able to deal with questions about those methods. Most of your students will not realize how difficult COB recovery really is. The students must avoid improvising on the methods taught and follow the step-by-step instructions in this manual. You will need to communicate the methods in this manual at least 4 times. You may find that after communicating the method 3 times that there will be a few students who will forget some of the steps, however, after completing the on-the-water drills should become proficient at the Lifesling® recovery method. The Lifesling® is a patented device in the United States and Canada and is trademarked in The United Kingdom, Sweden, Australia, New Zealand, and Germany. The Lifesling® is available in most marine stores throughout The United States, Canada, Europe, Australia and New Zealand. The Sailing Foundation is a nonprofit education foundation dedicated the advancement of sailing in the Pacific Northwest. It was founded in 1971 and has conducted a wide variety of educational programs.
I.
THE EQUIPMENT The Lifesling® is a horse collar device having a minimum of 20 pounds of flotation measuring 70 inches end to end and containing a lifting strap with D rings or loop in the end for the trailing line. The trailing line connecting the Lifesling® to the boat is polypropylene and floats. It is high visibility red or yellow and should be approximately three times the length of the boat. The standard length of the Lifesling® is 150', the Lifesling® 2 has 125'. If a boat has a wide turning radius a longer length of line may be required. It is also recommended that the Lifesling® owner tie overhand knots in the Lifesling® starting at the end of the bowline at about every 9" to a point which is above the lifelines of their boat. These knots can be used for a crew assisted lifting of a COB back on to the boat. The line and Lifesling® is stowed in a stuff bay or hard container so that upon deployment the line will come out without fouling. The container has several attachment options which are available for different types vessels. Generally, the Lifesling® should be attached to a pushpit within easy reach of the person doing the recovery. The lifting device is a block and tackle of three, four or five
parts. The length of line in the block and tackle should be of
sufficient length to be able to have the top part of the block and
tackle 10' above the top life line or hand rail. The block and tackle
should be set up to assure that the top block have the exit of the fall. The Lifesling® has a pocket which is designed to hold an ACR L8-7BP Lifesling® water activated light (See last sentence of this paragraph, the pocket is no longer recommended for the ACR light.), The Inflatable Lifesling® has a pocket in the lifting strap for an ACR L8-7BP water activated light. The Lifesling® 2 should have the ACR L8-7BP water activated light attached to it with plastic wire ties. It is recommended that the user install the water activated light to their Lifesling®. Recent tests by The Sailing Foundation recommend that the ACR L8-7BP water activated light be attached to the inside of the towing strap near the loops for the towing line for all Lifesling®'s The Lifesling® does not come with SOLAS retro-reflective tape on it (The commercial vessel version does but looses its Coast Guard Approval when used on a recreational vessels.). It is recommended that the user wrap the SOLAS tape around the front of the bollards on their Lifesling®. II. THE CLINIC: HOW TO TEACH THE LIFESLING® METHOD A. FORMAT The clinic format takes three parts: 1. Lecture, slides and/or video;
2. Manually rigging each boat; and 3. On-the-water drills. 1. Giving the Lecture The lecture should begin with any one of the several Case Histories which illustrate the need for the Lifesling® method. It is also necessary to get their attention and convince them that it is a serious subject. The text of the lecture follows, but several points are important to stress: a. Repetition It is necessary to make at least 4 repetitions of the procedure. Once
in the beginning of the lecture in brief, once using the gear as a prop,
once using diagrams (An easel prepared showing the steps of recovery is
very helpful.), and once during the slide show. It is essential that your lecture be well organized and that all
points be simply and clearly stated. Make sure your students understand,
but do not allow questions until after the slide show. Questions during
your lecture will only cause confusion. There are several questions that are commonly asked that you should
be prepared for. Studying the history and research will give you some
insight on how to respond. One example is the person (There is always
one) who will insist that the boarding ladder is the solution. In
examining the Case Histories, you will find at least three documented
cases of deaths involving use of a boarding ladder. There are also
statistics illustrating the weakness and loss of strength occurring
immediately following immersion and preventing use of the ladder. It's
important to note that upon immersion in cold water that within 5
minutes that strength in the fingers is substantially lost. The Sailing Foundation recommends that an hour and a half works best.
This will allow you about 45 minutes for the lecture and about ½ hour
for slides and/or video with 15 minutes for questions. Each lecturer's) will develop their own style, but be sure to cover the essential points. The following is a suggested lecture and standard slide show commentary. Copies of the slides are available from The Sailing Foundation at for the cost of duplication and mailing costs. The Sailing Foundation has found this format to be effective and suggest that you follow it closely.
THE LECTURE B: RIGGING THE BOATS The step-by-step process of rigging the boats has been taught in the lecture. It is essential that ALL boat handlers rig the boats at the dock prior to the drills to thoroughly understand the process and work out any questions. This part of the process contains the most room for deck seamanship errors so adequate attention MUST directed to it. The process itself appears in the lecture section and in attachments, but several points should be stressed. 1. Rigging Each instructor shall take the gear to each boat for rigging. (Some
boats may have their own gear so this should be used.) It is suggested
that all clinic boats be in one spot to save time. Many people are not familiar with use of block and tackle. The top
block identification should be stressed so that all the students know
which end (The end with the fall.) should be at the top. Make sure students physically hoist the tackle to at least 10' above the deck so that they can see what height is required. A person standing on the deck will help to illustrate the height requirement. 4. Tail of the Block and Tackle Depending upon the length of line in the block and tackle, you may have to be careful of hoisting the top of the block and tackle too high and losing the tail of the line out of the fair lead and around the winch. A stopper knot may not be a good idea as it may not pass through a fair lead to a winch. For clinic purposes and make sure that block and tackles contain at least 65 feet of line on a 3:1 block and tackle should normally be adequate for most boats. 5. Fair leads The tail of the block and tackle must have a deck fair lead to a
winch. Generally a jib car serves the purpose, but each boat has its own
requirement. A normal lead to the winch will avoid the override. Make
sure your students understand the set up and can duplicate it in an
emergency. It is well to illustrate the problems that will be caused by twists in the tackle line and make sure students understand the block and tackle well enough to sort it out. 7. Tying COB Off Illustrate the need to get the COB high up on the side of the boat and designate the appropriate place and method of securing the trailing line. 8. Lifesling® Attachment to the Boat Stress the need to tape or seize the bowline at the deck attachment. The polypropylene line may undo itself quickly without the seizing being done. 9. Block and Tackle Outside the Life Lines Make sure your students practice, several times, hooking the block
and tackle to the bowline in the Lifesling® OUTSIDE the lifelines. It
is a common mistake to inside the lifelines. Try to utilize existing leads and gear that is always on deck. Remember that during an emergency the rigging for a pickup should be automatic, non- complicating and quick. C. ON-THE -WATER DRILLS Common problems are found in the section "Problem Areas". This is intended as a guide. 1. Instructor Each boat must have an on-the-water instructor. The instructor must be a competent sailor familiar with the method and comfortable working on different boats. The instructors are there to coach and to PREVENT serious problems. This means taking the helm if necessary in dangerous situations. 2. Sail Selection 3. Number of Pickups Each boat should do at least one pickup for each student on board. If time allows, additional pickups can be done. 4. Weather and Sea Conditions This is a judgment call. Light air can be frustrating but power can
be used in the circling only. THE ENGINE MUST BE TURNED OFF ONCE THE COB
HAS CONTACTED THE Lifesling®. D. COMMON QUESTIONS 1. Boarding Ladder (Used as an example in the lecture section) The main points here are the difficult of getting to the first rung and the probable weakness of the victim particularly in rough seas. See Case Histories 13, 22 and 50. 2. Use of Another Halyard People commonly suggest use of a spinnaker halyard instead of a main halyard. If a spinnaker halyard is used the COB must be taken much farther forward to be raised from the water or the halyard must be brought back aft of the mast outboard of the shrouds. On some boats a halyard may jump the sheave if taken past the mid-ship aft. The use of a spinnaker halyard entails more time spent getting rigged to the block and tackle. The spinnaker halyard may also hang up on the spreaders if it is brought aft. Use of the main halyard seems best but remember each boat is different. Use a halyard that will not jump the sheave. 3. Won't the Main Halyard Jump the Sheave? It is possible, however in 100's of drills held by The Sailing Foundation, it has not happened. Use of the spinnaker or jib halyard can work. 4. Aren't My Winches Big Enough to Eliminate the Tackle? Possibly, but only those boats which have large halyard winches, usually 45' and above. The problem using halyards is having a long enough tail which will reach down over the life line and attach to the bowling and still be able pull up the victim and NOT come off the sheave. It is important that the COB may weigh as much a 300 pounds. 5. Why not Heave-To Instead of Dropping sails? A proper heave-to can be very effective. Lashing the helm down, releasing the main sheet and dousing the jib will immobilize the boat. However while a boat is hove to it can still drift. The Sailing Foundation sticks the standard "Quick Stop" method for the clinic. 6. Doesn't Dropping the Slotted Main Cause Problems? It may be messy, but it normally is not a problem. In an emergency the neatness of the deck is not important. The Sailing Foundation has successful held many tests with slotted mains with no resulting problems. 7. Do You Use Pole and Horseshoe? Our tests and those of the Naval Academy indicate the pole and horseshoe get deployed too far from the victim for the horseshoe to be usable. If the horseshoe is attached to the pole has shown in tests to foul the Lifesling®. However the pole by itself my help mark the vicinity of the COB. It is not recommended as a part of The Sailing Foundation method. 8. What Do I Do With the Spinnaker Up? The procedure is the same. With training the crew can drop the spinnaker down on the deck as the boat "stuffed" to windward. The most important thing is to stop the boat as close as possible to the COB. If done correctly, the boat will not broach (The boat must be turned very quickly into the wind.). A broach may be unpleasant, but it does stop the boat. It should be practiced with crews familiar the specific boat. 9. What Do I Do With the Tiller? It may be necessary to have some means to quickly tie off the tiller so that the boat will remain head to wind when you lower the sails. Sometimes the tail of a jib sheet can be used. If the boat doesn't stay head to wind while lowering the sails the boat can sail off towing the COB. 10. Can I Use My Tackle Without a Winch Back Up? Generally not. It may be possible. It is best to try with the weakest person lifting the heaviest person. 11. Can I Just Lift the COB with the Main Sheet or Vang from the Boom? No, the victim will not clear the lifelines. 12. What Side of the Boat do I Bring the Victim to? Generally the windward side. The main sail and the boom will not be in the way, however, it has been done successfully done on the leeward side. 13. What About an Unconscious Victim? If it is a single handed recovery, your chances are VERY slim. A boat hook MIGHT be used. If more than one rescuer is available, you are able to put a line on a crew member, drop the crew near the victim and the crew can assist the COB into the Lifesling® and both then lifted into the boat. This is obviously a very risky situation and the potential loss of two people MUST be considered. 14. Crewed Pickups On some boats a single handed pickup might not be realistic, i.e.
some large boats or very complicated boats. E. COMMON PROBLEMS 1. Towing Probably the most dangerous part of the whole procedure is the
potential of towing a victim. The Sailing Foundation tests show that at
4 knots the water is coming over the COB's head and at 4 ½ knots you
will drown them quickly. (It is important to note her that victims are
best towed with their back to the boat [180 degrees from the lifting
position]). The boat must be stopped immediately upon the COB's contact
with the Lifesling® and remain immobile as possible until the sails are
dropped. Constant observation of the victim must be maintained. For
drill purposes, The Sailing Foundation recommends the COB start with
their arm in the Lifesling® and get into the Lifesling® when the boat
is stopped and the sails are dropped. This is very probable and is accountable to ability to handling of a
boat and its turning radius which may be strange for the students on a
boat they don't normally handle. Fin keel boats are more likely to run
over the line. Sometime having students handle the boat prior putting a
COB in the water helps to get familiar handling characteristics. Again, taking the jib across when in danger of running down the COB will allow you to steer clear of the COB. Do not steer too close when upwind of the COB. 4. Tiller Falling Off 5. Tackle Upside Down Make sure the students understand the fall of the block and tackle is at the top. Standard 3:1 block and tackle sold by West Marine for this purpose have color coded blocks. Otherwise using tape can help to mark the top. 6. Twists in the Tackle Twists in block and tackles create friction which make lifting the COB difficult if not impossible. Twists occur when the bottom block turns, usually when the set is not 2 blocked. It is important to show the students that storing the block and tackle in a 2 blocked position will prevent twists from happening. If kept in a 2 blocked position prior to use will prevent a friction problem. F. RESPONSIBILITIES OF THE INSTRUCTORS 1. Be alert to problems and be ready for solutions. This requires
qualified sailors who can adapt to different boats and recognize
problems and react to them when they occur. III. HOW TO ORGANIZE A CLINIC Organization is essential in creating a successful clinic. The format that follows has been successful in reaching the largest number of students. 1. BASIC ELEMENTS a. Place for a lecture, slides and diagrams. It is recommended to combine the boat owners with other participants.
This allows you to teach the method to larger numbers of students. On
boats 25' and under, 2-3 students is recommended. On boats 25-40', 3-5
participants is recommended. Boats over 40', 6-7 people could be
accommodated. You may not need to advertise to have an adequate class, however, remember you will have to advertise in local magazines (paper) at least 4-6 weeks prior to the clinic date because of deadlines. Signing up and committing individuals is important to monitor class size for committed boats, instructors and COB's. If a fee is required, confirming with a check is suggested. 4. INSTRUCTORS On-the-water instructors should have enough time spent so they are
very familiar with the recovery method and are familiar with potential
problems. They should also be matched with boat in the size range in
which they are comfortable. (Don't put a dingy sailor on a 50' her.) COB's should be people you know who are in good health, are scuba divers or at a very minimum are comfortable in jumping off boats in wet/dry suits. Accepting COB's at the last minute is NOT recommended. 6. HOLD HARMLESS AGREEMENT It is highly recommended that Hold Harmless Agreement be drafted and signed by ALL participants including the teaching staff and students. 7. TIMING As mentioned previously, at very least, 4-6 weeks prior to the planned clinic advertising should go out. 8. COSTS If you charge $10-15 you should make enough to cover costs for
moorage, wet/dry suit rental, postage and printing. Any additional
"profit" can be used to purchase wet/dry suits and cover any
other future costs. 08:30-09:00 Registration/Coffee 10. DAY OF THE CLINIC Arrive at 08:00 to 08:15. Have name tags ready for students. Start
coffee. Start Clinic at 09:00 promptly. Make boat assignment at end of
clinic This addendum is a suggestion for recovery of COB from a power boat. It should be noted that this is only a recommendation. Because of the different configurations of power boats available in the market each power boat skipper should work on and develop a method which works best for their boat. To help develop a recovery technique, attaching a fender to a bucket in the water to simulate a COB works well. A. EQUIPMENT REQUIRED 1. Lifesling® B. RECOVERY TECHNIQUE Two methods of recovery can work for the power boat. The first method is to stop the boat immediately, turn the boat and approach the COB keeping the COB in sight at all times, approach to windward until the COB is abeam of the boat. Stop the boat and SHUT DOWN THE ENGINE(S) allowing the boat to drift down on the COB. Throw the Lifesling® to the COB. Pull the COB along side the boat tying the COB off on a cleat. Rig the 5 to 1 block and tackle to the lifting point (the portion with the cam cleat on the top) and then to the Lifesling® bowline, release the COB from the cleat and lift the COB on to the boat. The second method of recovery of a COB in a power boat situation in not unlike a sailboat recovery. They same basic techniques used in sailboat recoveries except the engine is used for the recovery. Also it should be known maneuvering will be different if a boat is single or double screw. This portion assumes that the steering station of the boat and the Lifesling® are stowed on the starboard side of the boat. 1. Stop the boat. Pull the throttle(s) back to idle, pull the gear
shift(s) to neutral and then to reverse. Put full throttle(s) on to stop
the boat. Once boat is stopped, pull the throttle(s) to idle and gear
shift to neutral. KEEP IN MIND THAT WHILE YOU ARE ATTEMPTING TO RECOVER THE COB TO KEEP
SAFELY AWAY FROM THE VICTIM BECAUSE THE TURNING OF THE SCREW(S) UNDER
THE BOAT CAN BE EXTREMELY FRIGHTENING FOR THE VICTIM AND A PERSON CAN BE
SEVERELY INJURED BY TURNING SCREW(S).
