![]() I saw the news earlier this week about the 591' ship Explorer with 681 college students on board getting hit by a 50' wave. What will happen if a 45' sailboat gets hit by the same wave ? Does it make a difference which way the boat is facing when it gets hit by a wave this big ? If it does then which way is the best way ? I was told that a good boat can correct itself even if a big wave turns it upside down. So can you just strap yourself to your bed and go to sleep ? Are the windows likely to break and let the water in so that the boat can sink after getting hit many times ? What else do you think can happen ? Thanks for your help. |

So, the _ship in question_ had windows in its bow?
From: Me Date: 2/4/2005 2:52 P.M. Eastern Standard Time Message-id: In article , (JAXAshby) wrote: of course it can. That ship was damaged because it turned broadside to the wave. You know it did, because it had windows knocked out. Having windows "Knocked Out", doesn't have anything to do with being broadside to the sea. In the Bering Sea, the Crab Fleet, routinely gets their windows broken by "Green Water", and those guys are out there every year, dealing with "High Seas". They just don't let themselves get broadside to the sea, but still lose windows. Me One who knows what "High Seas" really means....... |

Questions like these have always given me a good chuckle ;-) Anyone that
has spent any amount of time at sea or on the waterfront will have plenty of stories that relate to this. I'll spare you from hearing all of my "sea stories"... Having driven one ship in an Atlantic hurricane, another in a Pacific hurricane, a research ship off the coasts of Washington and Oregon during the entire months of November and December (first time I "lost my cookies" in over 30 years at sea), and numerous yachts and ships in gales, I have two bits of wisdom to pass on: 1. Nearly every ship (and most yachts for that matter) can withstand a heck of alot more lousey weather than the crew aboard her can. I know personally of numerous stories of people abandoning their yacht because the weather was just "too bad", only to have their yacht later found completely intact without a bit of damage. 2. If you're on a 45 foot yacht and the weather is severe enough for 50 foot seas... you ain't gonna be sleeping much... ;-) -- Paul =-----------------------------------= renewontime dot com FREE email reminder service for licensed mariners http://www.renewontime.com =-----------------------------------= |

I've heard more people say that was the only ship they ever got sick on than any other. She was here in Maine for a while but I don't know where she is now. -- Roger Long |

Was that the "Cayuse"? I've heard more people say that was the only ship
they ever got sick on than any other. She was here in Maine for a while but I don't know where she is now. Hi Roger, I'm guessing your asking why one ship might be more prone to causing seasickness than another? There are alot of determining factors, to name a few (I'm sure there are others, these are the ones that come to mind): Seas - The most obvious reason. The seas off the Washington / Oregon coast during the winter is about as bad as it gets. Gales hit every three days (like clockwork) and the seas are big and steep. I've been in bigger seas, but these seemed more uncomfortable. Vessel Motion - A vessel's size, obviously, has a big effect on it's motion at sea. Additionally, a more stable vessel will roll faster, thus making the motion more uncomfortable. The further you go from the vessel's center of gravity, the more motion you'll be subjected to. Yes, some ships are just more uncomfortable in a seaway than others, and the research ship I was on had a reputation for being a "puking machine". Since most of my waking hours were spent on the bridge, some 30-40 feet above sea level, it was a pretty "fun" ride. Below decks (in my bunk), it didn't seem quite as bad. The Irony was that our mission was to count whales, but because the weather was so bad, most of the scientists never left their bunks. Incidently, most cruise ships have "roll stabilizers" and "bilge keels". These usually do alot to reduce the vessel's roll. Health - If you're otherwise ill (or tired), sea sickness will definitely hit you faster. In my case, I had recently recovered from an inner ear infection, which I'm sure had alot to do with why I became sick. Smells - I know certain noxious smells trigger sea sickness in some people. Psychology - I am one of those that believe that if you think about it too much (or watch other folks that are sick) eventually you will get sick. Consequently, I do everything I can -not- to think about it. I know nothing about the circumstances with the cruise ship and students that everyone is talking about. I only caught a few seconds of the video that appeared on TV, so I'm in no position to judge or criticize, so I won't even try. The last I heard, she was docked here in Honolulu. Two other points on seasickness that are worth mentioning: One is that the seasickness pills I took while working off Oregon (Dramamine I think) worked like wonders for me. The other is that extended seasickness can be a -very- dangerous medical condition. If you (or one of your crew) should become sick, proper rest, meals and lots of fluids are -crucial-. Here's wishing everyone fair winds and following seas! -- Paul =-----------------------------------= renewontime dot com FREE email reminder service for licensed mariners http://www.renewontime.com =-----------------------------------= |

No, I was asking which particular ship you were referring to. I'm
primarily involved with oceanographic vessel design so I get to deal with motion and comfort questions a lot. I also hear lots of scuttlebutt and that particular vessel was legendary. Even after she came to Maine, people said the same thing about her. -- Roger Long "renewontime dot com" wrote in message ... Was that the "Cayuse"?

Sorry Roger, I missunderstood. The ship I was on was the NOAA ship McArthur. -- Paul =-----------------------------------= renewontime dot com FREE email reminder service for licensed mariners http://www.renewontime.com =-----------------------------------= |

I've been in bigger seas, but these seemed more uncomfortable. Seas and how a particular ship/boat handles them, vary as to what feels good or bad, depending on size, load condition, swell period, etc. Vessel Motion - A vessel's size, obviously, has a big effect on it's motion at sea. Additionally, a more stable vessel will roll faster, thus making the motion more uncomfortable. snip Couple all this with where are you working/quartered on the vessel. Surprisingly, I've noted that "accommodation" forward, tends to affect more people, than "accom" aft. BTW, Bilge Keels are great additions .... funny part is, that their best reduction in rolling ( note I said "rolling" ) is a mere 10%. As for blowing out windows/portholes.... heading is immaterial, vessel size is immaterial.... the right sea at the right moment, now, THAT'S important. otn |
