About 8-9 ears ago Ralph was commissioned by the Tuttles to build a Seydlitz hull plug, mold and 7 hulls, which were shipped to the Tuttles. He kept the first hull from the mold and has just decided to build the Seydlitz instead of a Mogami, partly because I'm building an Indefatigable Class battlecruiser with a hull from his mold. (When I complete the rebuilds of the Canarias and Suffolk we'll have a pair of well matched cruisers so a Mogami isn't needed yet.) Seydlitz is more than 10% longer than the Indefatigable, about 30% heavier, faster (24 vs 26 sec/100'), has 4.5 vs 4.0 combat units, tandem rudders vs parallel and multiple casemate guns for extra impenetrable area vs none. Despite those differences we think Indefatigable should be a well matched opponent, mainly due to better maneuverability. Ralph and I will get together later this month to mark and cut out the penetrable areas of the Seydlitz and Indefatigable hulls.
