Well, as Ronald Reagan used to say, 'there you go again!' First off, you don't know who I am, or WHAT I know, that is just an assumption on your part, the same sort of assumption that gets curators and conservators in trouble! I happen to be a yacht broker, that specializes in classic ships of all kinds, and have been to more marine surveys than you can shake a stick at! Truly, I have seen yachts and ships of all kinds, and all ages and what happens to them over the years, what can be done to repair them, assessing damages, costs and values. You can have a look at some of the ships I represent at www.yachtworld.com/aib
I have been at this for a number of years, and have myself been a sailor for about thirty five years. And by sailor, I mean gaff-rigged craft, schooners, ketches, cutters, catboats, Friendship Sloops, you name it! I have been a member of The Old Gaffers Association since 1995, and have assisted in the restoration of a couple Essex Smacks, and a Falmouth Oyster Boat of my own, sailing and racing in the many 'gaffer' events in the North Sea, the Western Isles of Scotland and in the Netherlands too. And one thing I have learned after all this, is that conservators, curators, and many other arm-chair experts seem to ask questions of everyone EXCEPT the people that might actually know something on the subject, and that is the folks on the waterfront, the ones who actually own and operate wooden ships, and have been working with them for years (the most notable exception is the Navy folks who had the hogging of USS Constitution repaired with the help of some schooner-builders from Maine and Essex Massachusetts). The point is that most of the knowledge and information about preserving a wooden ship IS around, and has been for centuries, but for the most part, conservators and curators don't seem to be able to ask the right questions of the right people (mostly they just talk among themselves).
One of the reasons Mystic Seaport is so outstanding, and the preservation of their vessels is at such a high level is that it also contains a WORKING SHIPYARD, which actually BUILDS ships ('Amistad' is one of their products), rather than just a collection of labelled ship-building tools with no real idea how any of this stuff works, or how ships go together (and come apart!), and this brings me to a final point.
While a ship in use is in and of itself a good thing that ensures the survival of that vessel, equally, perhaps even MORE important is how the USE of that ship preserves the skills required to operate and maintain it properly. You can have the very finest display of an old ship, but if there is no-one who knows and understands how it all works, you have lost more than half the science and story of that ship, along with all the social structure, traditions and interactions of her crew with the vessel itself. One of the best examples of this involves the 'Mayflower,' which was sailed over from the UK to Plymouth by Alan Villiers, now these many years ago. Villiers had crewed and captained some of the greatest Tall Ships of the age, around Cape Horn and damn near everywhere else. But he had never sailed an old-fashioned square-rigger like Mayflower, and particularly never a ship that had a spritsail, but no jibs, nor had anyone else still living.
Until that voyage, it was common 'expert knowledge' that a square rigger with no jibs would have a very hard time sailing to windward, and were mostly considered to be very much 'by the wind sailers.' What Villiers and the others found out was a very different story indeed. The spritsail (that small square sail slung below the bowsprit) was not designed to be set 'square' like everyone had previously thought (i.e. parallel with the waterline and only used when the wind was aft), but instead is designed to be twisted at a considerable angle, almost perpendicular to the waterline. When used in this fashion, the spritsail functions almost exactly like a jib, but since it is quite close to the water, it does not in any way bear heavily on the ship (does not make the ship heel over). It is in fact a very powerful sail, that allows even an old-fashioned high-pooped ship like Mayflower to sail very well to weather, thank you very much, yet was easy to control, and is the explanation for why such a sail survived for more than a hundred years AFTER the introduction of the jib with all its supposed benefits (even USS Constitution is equipped to carry one!). Yet this was never discovered or accounted for by conservators, curators, or historians, but by sailors, USING a ship that was equipped with one for the first time in a couple hundred years! And this is just ONE assumption by 'experts' that had stood for years, but was stood on its head by actual, practical usage.
It would be a wonderful thing if old ships could be effectively and perfectly preserved by museums, and certainly many museums have done as much as they can, but in the end, it is a losing game, and nothing lasts forever......'Nuff said?
