Apparently you didn't read my last post closely. A ship is NOT an airplane! An airplane can be carefully stowed inside a museum, and climate controlled, and you can't do the same with a ship! Cutty Sark has had, and is going to have so much replaced on her, or bastardized for the sake of commercialism that it really will have very little to do with the old ship! In other words, it is just a collection of old wood and iron, with very little context. If you want to see what a ship really looks like, feels like, and how they were built and operated, you will NEVER get that from a static display, no matter how 'original' it may claim to be! Take a charter on a Tall Ship, be a part of its crew AT SEA for a few days, and you will learn far more than any book, or display will EVER teach you! And that's a guarantee..... I think you have missed the point I have been trying to make, and that is, we ARE destroying many of these ships to satisfy our selfish desires, by putting them in a static museum, we are loving them to death! Cutty Sark now IS a 'pile of scrap' that used to be a beautiful clipper ship, and you and your children will NEVER see, or hear, or feel what it USED to be like (unless a replica is built and sailed).
It is important to understand that a ship's useful life is measured in decades, even centuries, whereas an airplanes useful life, or even it's level of technology is hopelessly obsolete within just a few years. A WW2 fighter could only be expected to be usefull for a couple years at best, even if it didn't get shot down or crashed. Thus, the airplane survivors that still exist really ARE 'ephemera,' and the social and other structures that go along with them, that put them in context are even more fleeting. To put ships in the same perspective as an old WW2 airplane, think if your visiting experience was not just seeing the plane fly ("you should have seen it..."), but included the whole aircrew, not 'pretending' to be a WW2 aircrew, but in fact ARE a WW2 aircrew, with all the rank structure, the mess hall, promotions, camaraderie, etc, etc, etc. And YOU can actually be a part of all that, not JUST an observer or reader of labels (though that is possible too, if you wish). That is what you get with a Tall Ship in active commission! Why? Because with a traditional Tall Ship there really is only one way to do things, the same way it has always been done, and for the same reasons. Can you understand the difference of experience?
As far as patterns, etc, there are excellent plans available for the construction of just about every Tall Ship, many of them the original builders plans, others been created after the fact to ensure the information is not lost. And these are available regardless of whether the actual ship is still in existence, for use in the future should someone wish to build a sistership.
Yes, Vasa has provided a wealth of detail about period ship-building practices, but far more important from a historical and anthropoligical view were all the personal items found aboard, the context they were found in, all of which revealed enormous amounts of information as to the social structure inherent in life aboard a ship of this period (its sudden loss created a snapshot of social and cultural history). But you know, the information about how the ship was built really didn't take that long to figure out. It is all the rest of the stuff aboard that has kept researchers busy ever since. One quick aside, although they know how Vasa was constructed, actually constructing a ship by these methods has turned out to be MUCH more difficult than anyone imagined! The great Dutch Flagship 'Zeven Provincien' was built in the same manner as Vasa, and the people in the Netherlands have been trying to build a replica in the same manner. Halfway through the construction of the lower hull they discovered they weren't able to do it, and have had to start over, this time using English style construction which is completely different. Why? Because the actual techniques used in the old Dutch ship-building method have quite simply been lost to time, and while we know the theory, and we even have diagrams of how to do it, the practical experience to do so has been lost, despite the best historical research by the best people.......
Finally, I am not suggesting that ANY old or historic ship should be simply destroyed, as that WOULD be a tragedy. All I am suggesting is that the old ships either be brought up to commission status, of if that is not possible, to build a replica and USE it, not only to understand what that ship was really all about, but to ALSO create a revenue stream to preserve as much as possible of the original. To do otherwise simply guarantees the eventual loss of the original, and all of its social and historical meaning (I'd rather see a real indian, being an indian, in the indian nations, than to look at a collection of arrowheads in a museum!)
