Hi Len and good evening to all the naval modelers on this forum.
In order not to disturb Duncan's work I decided to create a new topic to tell you my opinion regarding your interesting post. Thanks Len for these ideas to think and discuss things we like.
The discussion starts from the link indicated below.
Unfortunately I don't know of any real ship that has double wooden planking.
Just because I ignore it doesn't mean it doesn't exist at all.
Perhaps someone, in contemporary times, given the technical evolution of materials such as glues and paints, has thought of using a technique of this kind (which is typically modeling) also on real boats.
Regarding double planking on real ships, I'll just tell you what I'm sure of and then we can make (for pure pleasure) all the hypotheses we want and like to make.
Ships of the ancient era such as: Phoenix ships, Egyptian ships, Liburnians, triremes, quadriremes, quinqueremes of the various Greek and Roman polis did not have double planking.
The ships of the medieval era, such as: galere, galleys, galeotte, galeazze, of the Italian marinated cities such as Pisa, Genoa or Venice, the dromons of the Eastern Roman Empire, drakar vikings, the Hanseatic cocks, caravels, carracks, naos, of the European states they did not have double planking.
Ships of the modern era such as Spanish and European galleons did not have double planking.
Ships of the contemporary era such as warships of the line, brigs, frigates and schooners did not have double planking.
All historic wooden boats from the Adriatic and Tyrrhenian Sea for commercial use do not have double planking.
Even subsequently, as far as I know, double planking was never adopted for fast ocean-going clippers (such as those that transported tea from China to the United Kingdom).
Of course, the copper covers that were adopted to protect the hull had nothing to do with the double plating.
The list was not exhaustive and complete but only indicative, so I left out many other types of ships.
Correct me if I'm wrong.
The reasons why double plating is adopted in the modeling field are quite evident (obvious) and are always of an aesthetic nature.
I won't write these reasons now, I don't want to say everything.
The reasons why on real ships since the first boats the planking was not double lies, in my opinion, in the difficulty of making a double one combined with its total uselessness.
The single planking is the most logical and natural thing you can think of, although the techniques are different and here we can open another nice discussion.
While I don't know of any double-planked wooden ships, I imagine the weight problem can be overcome. I can halve the thickness of the planking so that by placing it double I will have the same thickness as the single one.
