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. 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. Good luck. Joe Cheers, Ellen |

"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?

Both...mostly pilots in training. Joe Cheers, Ellen |

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.

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 |

Badly enough that you'd could only hang on. You wouldn't be able to move. No doubt Ol Thom, a displacement hull has no chance of steering on plane. 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.

OzOne wrote What an absolute load of BULL****! You really need to do some ocean miles in a nice racing yacht. They are displacement, they will plane when surfing, and are perfectly controllable when doing it. Thank you, Oz1...of the 3 twins. Those two were trying to gang up on me. Even small displacement sailboats plane all the time. Like the J-24 and J-27. I've seen them do it. Duh. Cheers, Ellen |

OK, My displacement hull has no chance of steering on plane. I'd have to be up and skiing on the board trunk/ keel, and if so the rudder would be out of the water. Here see for yourself: http://sports.webshots.com/photo/205...63212926UfyOMU You really need to do some ocean miles in a nice racing yacht. I'm still waiting for you to invite me. They are displacement, they will plane when surfing, and are perfectly controllable when doing it. Are you are talking about a semi displacment hull? Joe Oz1...of the 3 twins. I welcome you to crackerbox palace, We've been expecting you. |

Joe,
That's exactly what they are takling about; Semi-planning! or even full planning!! Ole Thom |
