“As planned sailing ships” Cristiano Bettini: the origins of modern architecture of ships and yachts

“There is no vessel which, like a book, can take us to distant lands” – Emily Dickinson

For several years he was missing in Italian bibliography historiography of boating that concern the modern technical design of ships and yachts, and was talking to the audience that loves to know how it behooves the record number in mensura et.

The Edizioni ETS was able to capture this need and has recognized the merit of the book “How the planned sailing ships, the origins of modern architecture of ships and yachts” written by Admiral Cristiano Bettini.

If the tracking method of the plans of a traditional boat has been common for centuries and unchanged in the Mediterranean basin, different is the way that it has undertaken in the naval arsenals after the seventeenth century.

“The British have built the best type ships indicated by Newton and their admirals have assured me that these ships are much less good than those built with the experience rules” – Frederick the Great

What did he mean Frederick the Great in his letter to Voltaire of 1778?

Up to 1600 in shipbuilding he had never used the paper drawing as we understand it, with the orthogonal views, and the various sections, but was used a wooden boat shape that represented the main section, namely the central one.

Plotted on this timber, with the gradual movements around a point of rotation, it is traced all the rest of the ordinates of the vessel is towards the prow and towards the stern, is that this was small as a spear or as big as a ship.

The principle is based on three variables: the bottom of the shrinkage, the opening towards the outside of the ordinate (ie the ordinate that gradually flares outward), and finally the gradual reduction of the sidewall curvature.

As known to those who study naval architecture, the ordinate is not an arc, but a parable, which starts almost straight, and is gradually curving toward the keel.

This figure, the sixth, as they call it in the Adriatic, is used inside, and the design of the boat is born “within the shell.” This tracking method took place in a direct manner on the wood, allowing the master – the only one able to use it and to convey this knowledge to students – to discard any defects of the wood, to better exploit the arrangement of the grain, to obtain the minimum waste of material and therefore to avoid errors due today is the magnification of scale plans 1: 1 for both steps of copies from the paper drawing at room tracked in the pipeline.

This method has been overlooked by scholars and architects as they considered that it was not present geometry and design in the construction of traditional boats. It was thought that the boats were built by eye. The study of ancient forms, teaches us that it was actually the experience of shipwrights to dictate these forms and their harmonic development.

Tracing the history, the admiral Bettini has come to the heart of the big changes of the last decades of the 1600s and during the course of 1700, in which new physical and mathematical knowledge, merging crosswise to the geometrical disciplines, the development of metallurgy and knowledge material placed the foundations for the modern naval architecture development, aimed at developing more efficient ships, safer, better suited to their purpose.

Admiral Nelson, worried on this significant the passage quoted by Admiral Bettini: the inability to keep the sea of ​​many British ships, wrote to his Admiralty:

“If I have to keep an eye on the French, I have to be by sea; and if I have to be by sea have to face the bad weather; Therefore, if the vessels are not adequate to deal with the bad weather, they are useless “- Horatio Nelson

This shift became possible thanks to the Enlightenment, a time when great strides were made in mathematical analysis and the study of rational mechanics. It was in this cultural context that the mathematical and physical studies Euler (Basel, 1707 – St. Petersburg, 1783) and Bouguer (Le Croisic, 1698 – Paris, 1758) led to the developments on the balance theory based on the hulls representing metacentre the most emblematic step in this new era, even the base naval Architecture contemporary.

In the same years the studies on fluid dynamics and on the resistance to motion of solid bodies in them conducted by Simon Stevin (Brugge, 1548 – The Hague, 1620), Isaac Newton (Woolsthorpe-by-Colsterworth, 1642 – London, 1726) , the Bernoulli family (well 9 mathematicians and physicists), Leibnitz and later by Froude, were developed just in the marine sector.

“The contribution of great scientists also allowed through the entrance of physics and mathematics in the design, geometric application enhancement and aesthetic symmetry of the early nineteenth century out of the fog of uncertainty through mathematical genius Galois [ …]

History that of men, as well as technical, then, I have tried to tell, of genius and sacrifice, but also about politics among states for dynastic struggles, with all that this entailed in the pursuit of economic and military supremacy […] – Cristiano Bettini

Admiral Bettini has gutted a complex story, often hidden from the echo of naval battles and geographical discoveries enabled by these vessels and then by the great history of yachting and the pursuit of speed at sea.

“I tried, in conclusion, to act as an interpreter of this long history little known, especially in Italy, trying to reconcile history, technique and some general concepts of naval architecture, which I consider useful to enlarge the ranks of those who take interest in this fascinating evolution; so the book can also be read in a non-sequential, depending on the interests of the reader. – Cristiano Bettini

About the author:

Cristiano Bettini: Team admiral. During the long experience in military ships, both in staff roles Command, took part in all the major multinational missions and NATO in the country since 1982, after working both at the General Staff of the Navy and Defense both at the Interagency Command Summit. From 2002 to 2005 he was Defense Attaché and the Navy in Great Britain, with credit for Ireland. It has a matured so many years of direct experience in the field of training and deployment of personnel, first as a teacher and, later, in the rank of Admiral, in the positions of Commander of the Naval Academy, Inspector of Schools and Director of Naval Personnel Military, Deputy Chief of the Defense Staff. The efforts has added numerous professional experiences of sailing ships and yachts offshore, around the Mediterranean, Atlantic and Black Sea, extended to the field of design in the past. As commander of the yawl Corsaro II made two transatlantic sailing. [1]
