A big 'like' awaits completion of the work 🙂

Thank you Michele for starting this log. And you are right – a Venetian capital ship is a real gem among all other ships-of-the-line of this period. I have a special attitude towards Venetian shipbuilding in the early modern era (meaning 15-17th cent.), as I consider it as a kind of ancestor for the later constructions of the north of the continent. Back to the Venetian 18th century ships-of-the-line. Somewhat ironically, the best monograph on them I have in my home library, among quite many other books on Venetian shipbuilding, is the work in German by an Austrian Karl Klaus Körner – Das Erbe der Serenissima. Rekonstruktion und Restaurierung eines venezianischen Linienschiffsmodells von 1794 (Heeresgeschichtliches Museum, Wien 2010). Just from curiosity – have you consulted this monograph too while doing your historical research? I judge this particular work to be of the same high standard as other, much better-known monographs.

I see and am not pressing the issue further. I would only add that you are very lucky to have so many contemporary plans to work with. Thank you very much for your reply, Gérard.

Gérard, So many important and excellent news in your post, thank you very much for them. However, I would try to talk on La Néréïde only, to not risk pushing Michele into the discomfort area 🙂. And the hopes are that Michele would be interested too. Okay – while it is true that La Néréïde main vertical section is quite similar to that of Le Jazon, why not to try to reconstruct the whole hull shape of La Néréïde basing on the known conceptual methods from this period, so splendidly explained by Jean Boudriot in his works? Provided of course that such an attempt would suit the highest rigours of your work. It must be said that it is always some arbitrary choices are simply inevitable in such reconstructions anyway. And the reconstruction of the hull shape by contemporary methods, especially those of B. Ollivier, known to us after all, could be much satisfying and even better than that done for Le François 1683. In this place I must explain that IMHO, while J.-C. Lemineur made an excellent overall job, I am not quite happy with his choice of the curve of the greatest breadth forward in plan (tracé de la lisse du fort avant en plan) and the non-tangential arcs of vertical sections at the height of the greatest breadth line. And I suspect that the general approach adopted would be too detailed and too complex for the 17th century craftsmen/shipbuilders. Having said this, I am waiting impatiently for the monograph of La Néréïde, which is now so beautifully executed by Michele. I expect to find there detailed answers on the so much interesting issue of La Néréïde hull shaping.

Gérard, we are very happy to have a top expert like you on this forum, who have created the world's best and the most reliable ships' plans available. Not sure if I may, but you have also stated the striking news that you have started a monograph of La Néréïde a few years ago. Should we expect two monographs on this ship? Or perhaps you collaborate with J.-C. Lemineur? Or do you work on another monograph now? Or something else? Apologies if my questions are too indiscreet.

Thank you very much Gérard. I found your comments very informative, and the most surprising was your statement that J.-C. Lemineur adapted vertical sections of another ship to make his plans of La Néréïde. This explains much, as until now I have assumed that he has reconstructed the whole hull shape basing on the main frame profile as shown on the original plans/sections of La Néréïde (he had already made a similar try while reconstructing the frigate Le François 1683). Indeed, all the frigate plans show these visually very attractive forecastle 'wings', but only very few of those 'wings' are as much large as in this case, which made me curious. Now it is clear... Thanks again.

And I am curious as to why the forecastle on this ship is so extremely wide at the bow? Unfortunately, just this particular detail can not be derived directly from the original plans of this ship. Is it simply a more or less personal choice of the modern plans designer, J.-C. Lemineur? Perhaps Gérard Delacroix, present on this forum, can answer this?

This frigate has an incredibly sexy hull shape. If this were my build, I suppose I would probably stop building the model at this stage 🙂.

I had another look at the book La Frégate. Marine de France 1650–1850 by Jean Boudriot and Hubert Berti, and have now found 'all' the information on the frigate La Nereïde. The original plans are both extremely detailed and beautiful, and seem to lack only rigging and armament. Even complete drawings of the ship's decorations have survived. Indeed, the source documentation for this frigate is simply a dream.

Thank you very much in advance Michele! I was hoping you would elaborate on this issue.

And it is very interesting to note that in Venice, as late as the 2nd half of the 18th century, large ships were actually still being built with single frames („ad ordinata unica”), despite a comment above that they should be (or actually were?) built with double-frames („a doppia ordinata”).

Many thanks for posting these photos. After a quick browse through my books on the Venetian Navy, I found the following (these particular scans/photos are from a must-have for anyone interested, fantastic modern work – Vascelli e fregate della Serenissima. Navi di linea della Marina veneziana 1652–1797 by Guido Ercole). And I assume that your model is one of these four 1780 class ships shown below. Please don't forget to open a log on this model too. 🙂

Hello Amalio. Just to say, that until recently, I thought it was impossible to build a model of a wooden sailing ship so precisely and beautifully. Thanks.

What Venetian vessel? Is it shown somewhere? From what period and of what type?

Grazie mille per la risposta. Bene, nolens volens, aspetterò pazientemente le fotografie del tuo meraviglioso modello. Thank you very much for your reply. Well, nolens volens, I will wait patiently for the pictures of your wonderful model.

However, on balance, I would tend to follow Kevin's advice to simply fake the scarphs to avoid complicating the task. These scarphs are not desirable or essential elements per se, but just means to an end, i.e. combining small elements into larger ones. And they could have been located almost anywhere along the keel length, depending on the available material.

Can you show a side view as it is on the plans? May be quick'n'dirty photo of the side projection with gun ports shown (decorations not needed). Just to see the general layout of the ship.

What a pace of work! Do you work alone? Or do you manage a large team of employees!? 🙂

... and this only confirms that you made the scarf correctly, although perhaps somewhat unconsciously. 🙂

This is exactly what you have already done, and which can be seen in your post #14.

Depends on many factors which only you can anticipate. Say, the quality of the milling machine (like stiffness or repeatability) and the cutters themselves, the quality of your preparations and the actual work, like your ability to correctly program the CNC device, the right (or bad) setup of the part to be machined, the properties of the material to be milled (size, thickness, strength, stiffness) etc. The intricate shape of your keel (especially twisted surfaces) would probably require several passes of a cutter of quite small diameter, which would leave steps anyway. Still, if you feel you must try, go for it, at worst (or best) you will gain experience.

I think Scrubby has already explained it very convincingly, but to give you still an additional warning of what you will be dealing with, let me say that it is not only about the geometry, but also about the actual machining of such long, curved, tapered and slender parts: You will have to precisely position such parts on the flat table, you will have to hold them fast all along their length so that they do not bent under cutter pressure, you will have to change your cutters to different shapes, you will have to reposition your parts on the table to machine all sides, you will have to "zero" your different cutters each time you modify your setup. All of this you will have to do with a very tight repeatability to get just the acceptable results. This would be a nightmare even for very experienced machinist.

...and that shape of the bottom. Of unmistakably French (or rather Mediterranean) origin.

If you persist, they probably can. Yet, in this particular case, the level of complexity and effort required to do so would make it a hopelessly inefficient endeavour, and even more so for a one-off build. This is perhaps the last method I would consider.... Sorry.

Oh my...! New Ancre monograph! And of a frigate of the pre- "modern” concept! Fantastic news!
