![]() "Capt. JG" wrote in message Very important in cold water, when speed is vital. Not so important in warm water when you've got time to experiment a bit. My way: Actually, accuracy in getting the boat next to the MOB and getting the boat stopped is more important than speed. It's better to slow things down and get it right, unless you're talking about arctic waters. In 55 degree water, the person will be a live quite a long time.. many hours. However, they'll be unable to help themselves in 20 minutes or so. The most important thing to have happen is for the person to have a PFD, since this will extend their survival time. By 'speed' I meant 'short time to recover MOB'. I thought that shorthand was obvious since I was referring to the cold water problem . . . sorry if it confused you. Ladders on the stern are not a good way to recover someone, due to wave/boat slam. The boat is a lot more stable on the beam, with less chance of getting hit by the boat, the prop, etc. I guess you haven't tried this. Almost always, the boat will be making a small headway, so you'll be heaving your man in from astern. Set the boat up beam to the sea to minimise pitching. Even if it's pitching, a deep enough ladder (3 steps in the water) prevents him from going under the stern. And once he's got a pair of hands on the ladder sides, he can control his position in all but the most extreme conditions. A beam ladder has to be positioned by someone, which is a delay, the man has to be pulled forward (past that prop?), and the vessel pointed head to sea. And very few beam ladders (unless they're specially designed) go deep enough into the water to useful to a swimmer. Rope ladders, sometimes suggested, slide around the bilge and are very difficult to get your foot into. You've probably tried using the flexible steps to get into a life raft - b** useless. but why not just rig something with the tools available on the boat... you have winches, halyards... use them. Because it takes time, rehearsal and at least two on deck. You'll need one person to stabilise the boat's motion and hold it's heading. One more to rig the gear - and that'll take time, especialy if the MOB is chilling down and becoming clumsy at assisting you. OK, now he's attached. Next, you've got to lift him . . . now, at this stage the helm can usually move in to assist, and you'll need him. I've tried this (in the Med, nice and warm) with several variations. Halyard with four part tackle attached. Barrel sling. All methods ended up needing three on deck. Negotiating the lifelines was always an issue. Best to cut those free so the deck edge is clear, and there's not so far to lift the man (or woman - sorry if I'm not being PC here!) 3. When they can't climb in, send someone down to drag 'em in. Bad idea in most cases. I meant, send someone down ito the dinghy to drag him in. It's much easier to get him on board from a dinghy, even if incapacitated. So, you're going to leave him in the water and rig halyards etc instead? Maybe OK in warmer water, but a right chill off otherwise. But of course, with only two aboard, deciding to go down into the dinghy means putting two at risk versus one (in cold water) certainly lost. A. It's foolish to go to sea in a boat which can't be boarded from the water by a fit person. Even a couple of feet of freeboard will prevent most people from climbing on by themselves. Precisely my point. All craft should be fitted with a ladder which can easily be set up from within the water. Even at anchor. Swimming ashore after falling in is not always an option. Even some marinas don't have ladders to get you out of the water . . . in fact, ladders cope with the majority of MOB events.

You said "important in cold water." What I'm saying is that accept in arctic conditions, speed shouldn't be considered during a recovery. You should block it out of your mind as best as you can. Sure, shorter is better than longer, but even if it takes 30 minutes and you do it right, that's better than several passes of doing it wrong and saving 10 minutes. You're much more likely to injure the person in the water or the someone on the boat or the boat itself. Ladders on the stern are not a good way to recover someone, due to wave/boat slam. The boat is a lot more stable on the beam, with less chance of getting hit by the boat, the prop, etc. I guess you haven't tried this.

Rope ladders, sometimes suggested, slide around the bilge and are very difficult to get your foot into. You've probably tried using the flexible steps to get into a life raft - b** useless. Actually, we have. The boat should not be making "small headway," rather it should be completely stopped. Small headway is how fast exactly? 1 kt? Even at that speed you'll be hard-pressed. You're talking about someone who at best is totally freaked from having been in the water. They're not going to be doing anything except scrambling to get back on, and that assumes they can actually do something useful. Most MOBs don't fall off in benign conditions. 10 foot seas with lots of chop and whitecaps are pretty extreme if you have someone in the water. Pulled forward?? You need to stop the boat between the waves/wind and the person ON THE BEAM. If your boat is set up properly, deploying a beam ladder (which I don't think is a good idea either) takes a matter of seconds to deploy. Instead of a ladder, use the rest of the boat's equipment to recover the person. As soon as you attach them to the boat, you have plenty of time. but why not just rig something with the tools available on the boat... you have winches, halyards... use them. Because it takes time, rehearsal and at least two on deck. You'll need one person to stabilise the boat's motion and hold it's heading. One more to rig the gear - and that'll take time, especialy if the MOB is chilling down and becoming clumsy at assisting you. OK, now he's attached. Next, you've got to lift him . . . now, at this stage the helm can usually move in to assist, and you'll need him. No, it doesn't take excessive time. Yes, it takes practice! You can and I have done all of this by myself. You don't need anyone to "stabilize" the boat. Here are the basic steps: 0) Calm down and help whoever remains on the boat to do the same (panic kills faster than cold water) 1) return to the MOB (several methods - note that using the Lifesling, you can't drag the person around) 2) position the boat abeam of the MOB with the MOB on the leeward side (this protects the person and makes it easier to recover them) 3) stop all forward motion of the boat (anything less than this will make it very difficult to recover the MOB) 4) attach the MOB to the boat (now they can't go anywhere) 5) drop all sails and secure the boom (you don't want jib sheets and booms whipping around and you don't want the possibility of sailing away) 6) recover the MOB (use a winch, etc. to make it easier on everyone) I've tried this (in the Med, nice and warm) with several variations. Halyard with four part tackle attached. Barrel sling. All methods ended up needing three on deck. Negotiating the lifelines was always an issue. Best to cut those free so the deck edge is clear, and there's not so far to lift the man (or woman - sorry if I'm not being PC here!) You're just wrong or not doing this right. ONE person can do this, but yes you have to practice. 3. When they can't climb in, send someone down to drag 'em in. Down? You should almost never put a second person in the water if that's what you mean. Bad idea in most cases. I meant, send someone down ito the dinghy to drag him in. It's much easier to get him on board from a dinghy, even if incapacitated. So, you're going to leave him in the water and rig halyards etc instead? Maybe OK in warmer water, but a right chill off otherwise. But of course, with only two aboard, deciding to go down into the dinghy means putting two at risk versus one (in cold water) certainly lost. The dink is going to be, at best, highly unstable. Putting someone in the dink is going to be tricky and dangerous except in the most benign conditions, as you pretty much said. A. It's foolish to go to sea in a boat which can't be boarded from the water by a fit person. Even a couple of feet of freeboard will prevent most people from climbing on by themselves. Precisely my point. All craft should be fitted with a ladder which can easily be set up from within the water. Even at anchor. Swimming ashore after falling in is not always an option. Even some marinas don't have ladders to get you out of the water . . . in fact, ladders cope with the majority of MOB events. Your point doesn't quite cut it. You need to use the boat to help you recover someone. A boarding ladder should be available when you go swimming, but it isn't good enough for an MOB recovery. Learn and practice the proper recovery methods for an MOB. That's what is going to save someone's life.... not getting a nice boarding ladder for the stern. -- "j" ganz @@ www.sailnow.com |

![]() "Capt. JG" wrote in message ... "News f2s" wrote in message ... (lots of good comments snipped, review thread if needed) My thought with the inflatable in the water, assuming the MOB is able to get into it, is that it gets them safely out of the water before the mothership can get itself properly positioned for recovery (inflatable still tethered to m.s.). In the inflatable, they can regain composure and calm down a bit (if possible after the big splash). Bringing the m.s. abeam the inflatable, the MOB is protected from the hard surface of the m.s.'s hull, and they can "stand on the water," as it were, making recovery easier. In theory, but I think a theory that is worth consideration. Most people can't levitate themselves to water level, so having that "step up" advantage could be very useful. |

In theory, but I think a theory that is worth consideration. Most people can't levitate themselves to water level, so having that "step up" advantage could be very useful. Well, I certainly agree. I guess my main beef is with the notion that a real MOB situation is going to allow for it. If it does, that's just so much gravy (ok, I'll stop with the food metaphores g). We were practiciing crew recovery in the SF bay. The conditions for the bay were fairly typical those few days... 20kts, 3/4 ft chop, 4 kts current running. We had 4 instructors, 3 students, one safety boat. One of the instructors went in the water wearing a wetsuit, fins and a PFD. The conditions were such that the buoys were straining in the current. It was up to each student in turn to do the complete recovery, nuts to bolts, dropping sails, etc., with no help from anyone else, which included hoisting the MOB into the boat to complete the drill. The MOB was instructed not to help, except to protect himself from getting hit with something... no help to the person attempting the recovery. The best time was from a woman who weighed about 100 lbs soaking wet, hauling the 200 lbs instructor back onto the deck. In fact, she over did it and had to lower him, because she winched him up too high initially. Time from in the drink to on deck was about 2.5 minutes. My best time was about 4.5. We all (instructors included, except for the guy in the water) did the drill multiple times over several days. Even though we had a safety boat, I would call this as real-world as you can get without risking lives. -- "j" ganz @@ www.sailnow.com |

I would call for help in any mob where they did not climb back on board themselves within a couple of minutes. Actually, an MOB is not technically a mayday situation. Debatable, I think. If the MOB can not get on board unaided or at least quickly then he is in is in danger of hypothermia (in cold water) or possibly inhailing sea water (if rough) and if he cannot climb a ladder, probably injured ( or a fat MF..). Use Pan pan or lower call if you like, the CG gets to know whichever way you call them. Of course, this is a judgement call, and you would be within the guidelines to call one in for that, but trying for more than a few minutes is likely to get faster help. I would think that even in the most idea situation for a mayday, it would take near that long to get outside help. Here, about five minutes plus however long it takes at 30kts for an ILB to get there. For a chopper may be half an hour but you probably would not get one unless the situation really needed one. Well they can't get started until you have given up, doing it your way and you still have the possibility of hypothermia, secondary drowning, injury etc. to deal with even if you succeed. It no time to let pride that you can recover a MOB be tested at the expense of not seeking outside help. Also consider the short-handed situation of being distracted by yet another thing... vhf hailing, explanation, location identification, etc. Sure, you need to keep sight of the MOB first and foremost. I think you need to get a GPS MOB position anyhow. I can reach my mic from the helm so I don't think of using the radio as a problem. There is nothing to stop you trying to recover the MOB after making the call. There is so much debate about the best methods, one is left thinking that some of them don't work out well when it comes to the crunch. |
