100' Rogue Waves
Experts Baffled by Giant Walls Of Water Surfersvillage Global Surf News: - - Rogue waves are the stuff of legend and maritime myth: Giant waves, taller than highrise buildings, that rise out of calm seas. For years scientists and marine experts have dismissed such stories as superstition. Walls of water do not rise out of the blue, they said. But now research has revealed that 'killer waves' do exist and regularly devastate ships around the world. They defy all scientific understanding and no craft is capable of withstanding their impact. Rogue waves in the past have been ignored and regarded as rare events, now we are finally getting a handle on them and finding out how common they are. These mammoth events are not tidal waves or tsunamis, however. Nor are they caused by earthquakes or landslides. They are single, massive walls of water that rise up - for no known reason - and destroy dozens of ships and oil rigs every year. The story of the super-tanker Munchen is a classic example. She was one of the biggest ships ever built - the length of two-and-a-half football pitches - and unsinkable, it was claimed. But on 7 December, 1978, the pride of the German merchant navy, en route to America, disappeared off the face of the earth. All that was found of the Munchen and her 26 crew was a lifeboat that had suffered an incredible battering. Something extraordinary had destroyed the ship, concluded an official inquiry, which dismissed the Munchen's sinking as a highly unusual event that had no implications for other forms of shipping. Now scientists believe this calm assurance may be dangerously misguided. The destruction of the Munchen was anything but uncommon. Ships are going down all the time. If you read the maritime press there is a boat going down at least once a month, with the loss of crew usually measured in dozens of lives. In the past, bad maintenance or poor seamanship were blamed. Now scientists suspect the truth may be more bizarre. It is known that the Queen Mary was hit by a 75ft wall of water while carrying 15,000 troops in December 1942. The ship came within an ace of capsizing. Only a few years ago the British superliner Oriana was struck by a 70ft wave that smashed windows and sent water cascading through the ship, swamping six of its 10 decks. These giant waves cannot be predicted by standard meteorology. Waves - even in the worst of storms - should not reach much more than 40ft. The fact that walls of water up to 100ft are being observed regularly suggests that something is worryingly wrong with meteorology theory. Waves are normally caused by high winds whipping over the sea surface, but the origin of the freak waves baffles scientists. One theory suggests that waves and winds heading straight into powerful ocean currents may cause these huge walls of water to rise up out of the deep. Another suggests that, under certain conditions, waves can become unstable and start to suck in energy from neighbouring waves and so grow massively and rapidly. Researchers are still arguing over these ideas, but what is indisputable is the fact that the design of modern ships is inadequate for dealing with the freak waves. |

Yeah,,,the reference was to a huge Tsunami.....see above Thats why I said yeah, that will work, then asked a question about the original thread. I'll go first. I worry about my engine room hatch and cabin doors caving in.. in a thumble. I would hope to punch thru, and not roll or tumble, or pitch pole.... I dont think a big cat would have a chance of punching thru. My big wave tactic would be to motor sail straight into it full throttle, once the boat went vertical it would be a bad day/night.

Are you crazy, Joe? That'd never work. Did you see the Perfect Storm movie? Remember what happened when the Andrea Gail tried to do the same thing, It almost got to the top but when it was almost straight up and down it went over backwards. No, not a good plan. This is what you should try. Act like your boat's a big surfboard and do what surfers do. Check out the wave and look for the side that's getting shorter. Turn your boat so it's going towards the small side about forty five degrees to the wave. Then wait till the wave catches up and as you go up it keep steering forty five degrees or so. Pretty soon you'll be going very fast. You'll be surfing along the bottom part to middle part of the wave away from the side where it's big and breaking. The face of the wave will give you the power to surf along. You can adjust your angle to control your speed. You should try to sheet your sails in tight because the apparent wind is going to be forward. If your lucky pretty soon the wave's gonna get smaller and smaller. They're tall but probably not more than a couple of miles wide. If you can keep control you can just ride the wave till it gets small enough to handle. You've seen surfers do it on TV. There's no reason a boat couldn't do it too. Cheers, Ellen |

"Joe" wrote good suggestion for a planing hull, bad bad ideal for a non-planning hull, drag would have you pitch poling right away. I don't think so, Joe. What's planing and what's non-planing? It's only so on a horizontal surface. On tilted water it has no meaning. A sailboat hull can't plane on flat water. There's not enough power in the engine or sails to make it go fast enough. But it can when it's going downhill when the hill's steep enough. Gravity gives you enough power. Your boat would be able to break out of the wave train it makes. The reason is because the front of the bow wave is almost horizontal on a steep hill of water instead of being too steep to get up like it is on horizontal water. What do you think? Cheers, Ellen |

What's planing and what's non-planing? Planing allows the boat to go faster by using its speed and hull shape to lift the front part of the hull out of the water. The boat travels on top of the water, greatly reducing the hydrodynamic drag on the vessel. The increase in aerodynamic drag is small by comparison, and can be compensated for by the increased power from the sails due to the faster speed of the craft, and by the crew trimming the sails. The term 'planing' refers to a craft which is predominantly supported by hydrodynamic lift, rather than hydrostatic lift (bouyancy). The extent to which a boat is said to be planing is usually derived from the dimensionless 'Froude Number'. The earliest documented planing sailboat was a proa built in 1898 by Commodore Ralph Munroe; it was capable of speeds of more than twice the hull speed. Planing a sailing dinghy was first popularised by Uffa Fox in Britain. In 1928 Uffa Fox introduced planing to the racing world in his International 14 dinghy, the Avenger. It had been designed with a hull shape which permitted planing. He gained 52 first places, two seconds and three third places out of 57 race starts that year. Obviously this performance had an impact: other designers took on his ideas and developed them. Over the years, most dinghies have acquired some ability to plane, and there are now many high-performance dinghies (usually called skiffs, see these examples, or these in [1]), which will plane even in light winds, at all points of sail. How planing works Normally a non-planing, displacement, hull is restricted in its maximum speed by a formula related to its overall length , where HSPD (in knots) is maximum hull speed, and LWL is the hull length in feet at waterline. This speed is maximised when the boat sits between the bow and stern waves, with no intervening self-caused waves along its length. At low speeds, a hydroplaning hull acts as a displacement hull. But, when the speed increases the hull begins acting as a planing hull. However, when the boat begins to plane the formula becomes irrelevant since the boat is climbing its own bow-wave. The bow rises slightly as it starts by mounting its own bow wave. When it reaches the speed where it overtakes the bow wave, the bow resumes its normal attitude. The boat can often be seen to leave its stern-wave some distance behind it. The hull is now planing. Beginning to plane is the aquatic, and less dramatic, equivalent of an aeroplane breaking the sound barrier. The aeroplane at Mach 1 begins to pierce and go beyond its own 'bow wave', i.e. the compressed layers of air on its front surfaces and ahead of it. A hydroplaning hull travels faster and more efficiently than a displacement hull of comparable size due to two factors: less area of the hull is in contact with the water. This reduces the friction on the hull caused by water. the hull is displacing less water from its path. Water is relatively heavy and a displacing hull must displace its own weight of water. The characteristics of a planing hull are that it is narrow at the prow, with a broader beam towards the rear. The shape of the underneath of the rear of a larger, planing, powerboat is often V shaped. To plane, the power to weight ratio must be high; sailing boats need a good sail area and powerboats need a highly powered engine. Note that under some high wind conditions, very light craft (such as windsurfers and kitesurfers) can actually be pulled up onto the surface of the water, or into the air, by the upward lift of the sail alone. Although this certainly reduces water resistance, it is probably better described as flying, rather than hydroplaning. It is also not a sustainable state, as sailing (or kite flying) involves the extraction of energy from the shear force between the wind and the water. If the entire hull leaves the water, the craft will quickly come to rest relative to the wind, and lose its lifting/driving force. How to plane in a sailing boat Planing can happen in a suitably designed boat in moderate to strong winds if the crew do some or all of the following: Sail on a reach or broad reach to begin Slacken the jib Raise the centreboard Increase the speed Keep the hull level, trapeze if necessary Observe the wake until it is smooth and fast Move the crew weight increasingly towards the rear to begin and to sustain planing Sheet in as speed increases, and apparent wind correspondingly moves forward Keep the boat flat and level Bear away to maintain speed as necessary Flick or pump the sails (although there are restrictions on doing this in a race) While planing, keep control of the waves and steer through them, avoiding to increase speed to collide with the wave in front. Also, in dinghies, keep good control of the sail power. A small change in wind direction can easily cause a capsize, watch also out for gybes. Boat control becomes easier as planing begins, but fast reactions are often needed to get there, to keep the speed up and to keep the boat level. Crew balance and trim are vital, as are sail trimming and minimal centreboard It's only so on a horizontal surface. On tilted water it has no meaning. A sailboat hull can't plane on flat water. There's not enough power in the engine or sails to make it go fast enough. But it can when it's going downhill when the hill's steep enough. Gravity gives you enough power. Your boat would be able to break out of the wave train it makes. The reason is because the front of the bow wave is almost horizontal on a steep hill of water instead of being too steep to get up like it is on horizontal water. What do you think? I think before I got 65,000 lbs on plane with a displacement hull I would be in a vertical position racing to stuff the bow deep into the wave leaving to a classic pitchpole like this: http://www.bymnews.com/photos/albums...ormal_Git1.jpg Joe Cheers, Ellen |

"Joe" wrote http://www.bymnews.com/photos/albums...ormal_Git1.jpg Those trimarans certainly can go fast enough to pitchpole. And you're right it's usually because they go so fast they stuff the bow into the back of a wave. Dame Ellen can have them. But, I don't think a monohull with ballast on the bottom would suffer such a fate. They just don't go so fast even down the face of a wave. They would stay on the wave and never get a chance to hit the next wave in the backside. Also, if your going across the wave at 45 degrees like a surfer you stay in place on the face of the wave even if your going very fast. You'd have to have a boat with good rudder control. But, I think it would be a safer thing to do than trying to go straight up a huge wave. You'd just have to hang in there till the wave wore itself out. A wave that big just can't be that wide for more than a mile or two. What would that be if your surfing along at ten to fifteen knots? About fifteen minutes? Doable. Cheers, Ellen |

If you thinking of kicking out in front of a tube then you need to be in a area a wave is breaking. A rouge can be a wall 100+ ft tall, you try to run down the face of a wall at 45 you going to tube roll and be in a waching machine for quite a while. Punching thru and over is your only hope. http://lifesjestbook.typepad.com/men..._storm_001.jpg You'd have to have a boat with good rudder control.

"Joe" wrote http://lifesjestbook.typepad.com/men..._storm_001.jpg That picture shows how far the Andrea Gail has to fall and tumble. You just can't punch through a wave with a little boat. (unless your driving a submarine) You can't make a whole boat sink under a wave with power. It will stay on the surface. If it's long, really long, longer than the wave length then maybe the bow will go under for a few seconds as the wave sweeps along the hull but the whole boat isn't punching under the surface. Back to the small boat.... The minute water from the wave gets inside the diesel air intake there goes the engine. Then the boat's dead in the water. Under water if the crest falls on it. So what happens you get rolled and slammed off the top of the wave all the way to the bottom. http://www.indiana.edu/%7Eg131/waves4.gif If the Andrea Gail would've tried to surf the wave to get out of the way of the breaking crest they would've had a chance at least. The way they tried to do it was a death sentence. I don't think real ships captains would try to power straight up a wave like that. Where's Otn when we need him? I bet he wouldn't power his pilot boat with it's two powerful diesels straight up a rogue wave face. That reminds me something I was gonna ask him..... Who drives the pilot boat out to the ship and who drives it back? Do pilots ever drive the pilot boat or do they just go along for the ride and pilot the ships they're put on. Cheers, Ellen |

I know they would, you gave good reason, most ships have a longer wave length and will punch thru. I think whenever the wave height is longer than your waterline and has a shorter length then you in deep trouble and are at the mercy of the sea no matter what you do. Where's Otn when we need him?

Joe,
Neal has made that statement about waves before and as usual he's full of S--t. His whole scenario is riddled with wrong stupid assumption. The first and dumbest is comparing a displacement hull with a Surf board. Can anyone that has ever been in a Sea way ever tried to control a displacement hull in near free fall on the face of a wave with a rudder? A wave that large creates a sucking action into the wave. Something he is ignoring or is completely unaware of. He assumes his hull would be on a level plane like a surf board when in reality it would be heeled badly. Badly enough that you'd could only hang on. You wouldn't be able to move. When he make statements like that, it is because he is speaking through a "Sock-puppet" but I've read his mentality on waves before and it is DAMN STUPID AND DANGEROUS!! His "Cut the Mustard" carries a broken Boom, Which according to him, happened in a wave entering a channel. DON"T LISTEN TO HIM! I don't think he has ever Battened Down and had the let the Vessel take care of him and itself. He just doesn't know. http://community.webtv.net/tassail/ILLDRINKTOTHAT http://community.webtv.net/tassail/GOODNITE |

Badly enough that you'd could only hang on. You wouldn't be able to move. I don't know about what Capt. Neal said but if he said to try surfing down and across the wave then he's got it right IMO. It makes perfect sense to me. I'm glad we think alike. Your wrong about a wave making a sucking action. Look at the link I gave Joe. It has a little circle in the wave. It shows which way the water goes. The arrows show the opposite of a sucking action. Being a woman I know all about sucking action. :-). Just kidding, don't get all excited, Tom. You said the hull would be heeled badly. I don't think so. Rogue waves travel fast. Very fast. Just imagine the apparent wind. If the wave was going fifty miles an hour and the wind was calm you'd have a fifty miles an hour wind at the top of the wave. That's what blows the spray back. But at the bottom of the wave the wind would be less but still strong enough to keep the boat level. It would be blowing against the tilt of the wave so things would balance. That's why I said to sheet the sails in tight. When he make statements like that, it is because he is speaking through a "Sock-puppet" but I've read his mentality on waves before and it is DAMN STUPID AND DANGEROUS!! His "Cut the Mustard" carries a broken Boom, Which according to him, happened in a wave entering a channel. Whatever, but it sound like he's got it right to me..... Tom, I was reading a good book last night. This is what it says about big waves and sailing in them. It agrees with what I'm saying. That's mostly why I said it. "4) If truly enormous seas threaten to engulf the vessel you can try oil...... You can cut away some or all the warps and begin to steer by hand, bearing off a little when the yacht rises on a big sea. This will require careful steering, and crew exhaustion will become a factor. Let's hope you will never get to this point." This is the fourth of four steps to sailing in heavy weather. The first three are heave to, lie ahull, run with the storm with warps trailing astern. Know who wrote it? Hal Roth in his book, After 50,000 Miles. So your telling people to not listen to Hal Roth, Duh, I think he's got more experience even than Capt. Neal does. And certainly much more than you do...... Joe's talking about one big rogue wave. Exhaustion's no problem, careful steering's the most important thing. Just like I said. Cheers, Ellen |

Can you just imagine "Ellen" standing in the cockpit of her Tangerine like a surfer kicking out of a 100 footer...hehehehe. Even the planing boats getting hit from astern have little chance as discovered by Hatfield from Canada. The 7880 nm Leg 4 of Around Alone from Tauranga NZ to Salvador (Brazil) round the notoriously rough Cape Horn has claimed two booms, two masts, damaged two keels caused a pitch-poling (end-over-end capsize) and forced Kiwi Graham Dalton on his Open 60 Hexagon to retire from the race entirely. The ports of Mar del Plata and Ushuaia in southern Argentina and Port Stanley in the Falkland Islands have been extremely busy receiving the yachts, effecting emergency repairs before sending the competitors on their way. Winds of around 70 knots and 40 foot high waves have been recorded and Canadian skipper Derek Hatfield (before dismasting his Open 40 Spirit of Canada) joined a long line of mariners who have been fooled by Deigo Ramirez, a small rocky archipelago 30 miles west of Cape Horn that have scared the fillings out of many sailors who have come up on the group in the middle of the night and suddenly seen the lights on the wrong side of the boat. Hatfield's pitch-poling story is pretty amazing: It was sometime mid-afternoon when the wave that had his name on it came up from behind. "I was so exhausted that I could hardly think, but when I heard the wave I knew that I was in trouble. It was not as big as some of the others, but was breaking and it made a huge roar as it approached the boat. In seconds we were falling down the face of it until the bow dug in and then we pitch-poled. The boat went straight up and then fell over sideways. I was at the back of the boat and got flung forward, and the next thing I knew I was in the water under the boat." Derek continued his story. "I heard the water gurgling and knew that I was under the boat, then all of a sudden I heard loud explosions that reverberated through the water and I knew in a instant that the mast was breaking. It was unreal. Gurgling water and huge bangs. Suddenly without the mast the boat came back upright and I was dragged back on deck." Derek is amazed and gratified by the outpouring of support he has been receiving including Emma Richards sponsor Andrew Pindar offer to fund a spare mast is starting to feel a bit confident that he might just be able to get back into the race.

Is there something in the air? Or is it that time of the month for you both? :-) It's just like a man to refuse to admit it when he's wrong. Then comes curse words. Then playing the word game. Oh, it's not planing, it's surfing. Gag me with a spoon. We're talking about going down/across waves fast. Call it anything you want, I don't really care but be man enough to admit the boat's going faster than it ever can on flat water. And it's easy to control unless it's poorly designed. Displacement monohull sailboats surf all the time. Go out to sea and get in some big waves with the wind behind you and you'll see. When your going down a big wave look at the speedometer. It will say your going ten or fifteen knots. That's surfing. I've seen J-24 boats surfing on flat water if it's windy enough and they have the big spinnaker up. Duh! You and Tom are fake sailors. If you were real you'd know these basic things. Cheers, Ellen |
