Looking over this springsharp for the Sanxay Straits, I came to a realization. Its not a bad ship. I also noticed that it has a "natural" speed of 26 knots, so I redid the numbers, reran it, and still came up with the same results. So, I've been thinking... instead of considering this to be an underarmored battleship, it could very well be a damn fine battlecruiser instead. I believe I may reclassify this thing to a battlecruiser.
