Instead, I merely point out that it would be an accurate representation of what the Royal Alatian (later Imperial) Navy would be building at the height of their wooden-ship period.
Well, except that they would be using the junk rig. But apart from that.
To be fair, I should probably have said evolved junk rig.
After all, on Earth, the primary user of the junk rig was China, whose uses for it were (a) primarily mercantile, and (b) primarily fluvial and littoral. A few abortive experiments such as Cheng Ho’s expeditions aside, it was a land empire, not inclined to naval power.
Alatia, by contrast, was very much a naval power, so you have to think on what the junk rig might have become if the British Royal Navy had turned their collective naval architects on to relentlessly improving its performance.
Such evidence as we have from modern experimenters with modified junk rigs seem to bear out the possibility of this, incidentally - specifically, that battens able to flex and/or be independently sheeted and create shape in the junk sail increase both speed and ability to sail close-hauled, as do intentionally cambered junk sails vis-a-vis the original flat-sailed rigs, to the point where they can outperform current Bermuda rigs in these areas.
Unfortunately, all the evidence I’ve found comes from small sailboats as no-one’s building tall ships quite that experimental these days, but I think the extrapolation is valid enough for fictional work.
And now I want to see someone experimenting with a junk rig in the Sydney-to-Hobart Yacht Race, which has had some interesting experimental technology over the years. And is hyper-competitive enough that if it looks like a promising line of tech, the experimental super-maxis will leap all over it.
The death toll, possibly? It’s not a safe race, so the ones with the deep pockets willing to really push the tech would probably want to see a smaller version at least manage to finish successfully first.
Did the Alatians have access to 100-meter long single pieces of ship grade wood, the local equivalent of redwoods? Because I think that’s what you’d need for masts and spars that size.
Even in our world we were using split masts and spars by that point in the Age of Sail, you don’t need the entire length as one contiguous piece of wood.
Although, all things being said, insofar as Alatia is as forested as most of Eliéra, the eldrae take silviculture very seriously, and it’s always been a major naval power, one may safely assume that the Growing of Masts is a Serious Matter, with future ship parts being carefully tended by a corps of Admiralty-contracted dedicated treekeepers.
