Okay two comments in my looking for advice of ships brought some more questions.. I figured I should be put somewhere else... if not sorry for the cross post. Okay so the later Arizona which no longer has casement guns but still the windowed casements counts as casements in regards to impenetrable hull area? ie.www.navsource.org/archives/01/013818.jpg the forward and rear old casement guns no longer has casement guns as per www.navsource.org/archives/01/013807.jpg. So if I were to build the later 30's era Pennsylvania I would have added "protection" of casements inpenetrable areas even w/ out the actual guns being depicted there? Both IRC and MWC has this rule stated in the same words. "On ships which have casemate mounted guns, the cupolas may be constructed of impenetrable material. A 1/8" wide strip on each side of the cupola may also be impenetrable. If a flat bulkhead area between cupolas is inset more than 1/2" from the edge of the gunwale the entire casemate area (cupolas and all flat bulkhead areas inset greater than 1/2") may be made impenetrable." Okay I am either dense in my understanding of inline rudders or they are the daftest concept of dual rudders. So inline would mean one rudder in front of each other like say.. time for some bad ascii art.. Inline: | | Tandem | | Is this a correct depiction? If this is correct I have never seen it in my life. Plus, how would a rudder behind the other would help in the steering of a vessel? I would think the turbulences created by the first rudder would greatly reduce the efficiency of the second rudder.
tandem is one in front of the other... http://dictionary.reference.com/browse/tandem the Yamato's had tandem rudders, a large one far aft and a smaller one a bit further forwards... the front rudder was not terribly useful.... Other ships, such as the Iowas had the rudders side by side at the same spot as measured lengthwise along the keel, offset to either side. Some folks use inline for that, although I am not sure that is the best word to use (and some folks just mix them up occasionally or use them as synonyms)... hence I usually try to talk about them as side by side...
The inline rudders get increased rudder area in the IRC because the Axis campaigned for it because the Britsh got increased rudder area due to their side by side placement. It was a weak point in the rules meeting. Casements can give greater protection but only to the above hull areas, so ... they do not increse surviablity but do lessen the points given except in those vessels that are almost all casements. IMHO Marty Hayes
The pre 1930 Arizona with the side casemates have huge cupolas. Frank is rebuilding his adding them back in. It will limit allot of the stern gun damage that the center of the ship takes.
I was going to pre date my arizona also but would have needed to remove about 1 inch from the beam of the ship. The middle area of the ship which had casemates but does not any longer (flat) is all penetratable. Rudders are single, in line (tandam) or side by side depending on ship.
Well, for one thing: A casement is a type of window, with panels that hinge vertically on the outer sides. A casemate is an armored structure with openings for guns to fire out. JM
Thanks all I am no longer clueless on casements/casemates and inline/tandem rudders.. still clueless in other areas mind you =D
