A fairly substantial result, Larry conceded. The flush-decked U.S. Navy sloop-of-war upon which the design was based had been one hundred and forty-eight feet long between perpendiculars, with a beam of just under thirty-nine feet. That meant her hull was about thirty feet shorter than the ironclads Simpson was building in Magdeburg, but since she was going to have a bowsprit over sixty feet long, Eddie suspected no one would notice. And whereas Simpson's ships were going to be ugly, boxy vessels, with an uncompromising brutality of line and form, Gustavus' ship retained the graceful lines crafted by her original 19 th -century architect. The only real change the emperor's builders had made in the enlarged builder's draft Grantville copiers had produced from Chapelle's carefully redrawn plans had been to increase the height of the bulwarks from just under five feet to approximately seven. Once the armor plate being produced in the local rolling mill was bolted to the outside of the hull, that would provide head-high protection for her gun crews. Of course, hanging that much iron plate on the outside of the hull was going to add about two hundred tons to her weight, so even with the reduction in her broadside armament, she was going to draw close to twenty-four feet, which was a bit deep but manageable for the Baltic.
Personally, Larry suspected that the impressiveness of Gustavus' new ship was the real reason the emperor had insisted upon building her here in Luebeck. Certainly, she made a lasting impression on anyone who entered or visited the city's harbor… including the town's burghers and authorities.
The harbor itself swarmed with shipping of every description. According to Ms. Mailey, Luebeck had managed to sit out the Thirty Years War in the past of Larry's own world pretty much unscathed, maintaining its neutrality with shrewd diplomacy. This time around, it didn't look like it was going to be quite so lucky, because in
Gustav Adolf needed a solid base for his logistics, and Luebeck was one of only a few North German ports suitable for the part. Wismar, Rostock and Stralsund were already held by the Swedes and incorporated into the CPE, and it was fairly obvious to everyone that Luebeck was going to join them in the end. The only real question was how much independence the old Hanseatic League city was going to retain, and that was what Gustavus' current diplomatic dance with the city's authorities was all about.
Unlike Hamburg, which dominated the estuary of the Elbe, Luebeck was on the Baltic side of the Jutland Peninsula. That was important, because as long as Denmark was in a position to close the Kattegat to shipping and so deny Sweden access to the North Sea, Hamburg was completely unsuitable as a supply port connecting Sweden itself to the continental portions of Gustav's CPE.
Not that Luebeck was a perfect substitute for Hamburg. The Stecknitz Canal, which linked the city to the Elbe River at Lauenburg, upriver from Hamburg, had been designed only to accommodate the barges of the salt trade. Those were large enough to haul cargos that could be broken up into fairly small chunks, but not for the sort of heavy transport the CPE and the United States envisioned. That could be fixed, however, and Gustavus' engineers, assisted by American survey crews, were already busy designing the new and improved Stecknitz which would serve their needs just fine.
More immediately, however, there was the fact that any of the North German ports were close enough to Christian IV's Denmark for the Danish Navy to threaten their lines of communication with Sweden. Luebeck, in fact, was more vulnerable to Danish interference than most of them. But that was what the Swedish Navy was for. The Danes had learned the hard way that the Swedes were not to be trifled with, and the squadron of Admiral Karl Karlsson Gyllenhjelm had been stationed at Luebeck to remind Christian of that.
