Appears to be a steamer only, no sail capability.  She'll have to stop along the way to recoal on voyages to the Cape Colony or to Ceylon or the DEI.

True, I forgot that bit.  I'll have to re-do the design a little.  Add in some extra weight.  I'm trying to replicate as exactly as possible the original.  Obviously not possible.

I thought the DEI didn't exist here...

If you are trying to replicate HMS Euphrates as exactly as possible, I would think that she's too long. Wiki indicates that the length overall is 360 feet and I would assume that that length includes the Bowsprit on the ship and the overhang of the stern. Below my attempt. Not quite there, but I would think that it looks reasonable for the post 1873 11 knot Euphrates.

Some countries will have colonial holdings to start with.  The Dutch, in particular, with their small home population, NEED some colonies to have a prayer of keeping up with the neighbors.  Don't worry, there's plenty of territory to plant the flag on, even without having to kick some other non-natives out first to do it.

> Half of natural speed (10 knots) is 7.4 knots for 5% of normal displacement

The ship's natural speed is actually 14.8 knots, so all the calculations are right, just the text is wrong.

Very short (vertically) and thin main belt, with a thicker upper belt.  Crew will be fairly well protected, hull a little less so.

Darman

I wanted the same standard of protection from main belt to upper belt but I didn't want too much armor below the waterline.  So main belt got shortened.

Don't know of anything that does not allow you to set trim other than the springstyle notes regarding submarines so I would trim the ship a bit more so that the stability is a bit higher.
