I'll assume that this may have been sparked off by my revisioning of the Solomani Navy, specifically in the small ship category.
The specific reason that I discarded the hundred tonner as the primary scouting hull by the Solomani is that I don't view it under current design rles as economically viable as a civilian trader, nor the capacity to fulfil the roles hat a purely naval service would expect it to accomplish.
This is to be explained that instead of the Solomani Navy trying to cram everything in, they've decided just to mass produce two hundred tonners, so that when they do retire the hulls, stripped off anything sensitive, it can easily be refirbished or converted to private and commercial use helped by the fact that even a more limited number of alphabet selection exists, that true economy of scale is encouraged and practised.
