Last time I looked there was no place on the National Archives (NARA) web site to search for ship and submarine plans. Here is the NARA search page: https://www.archives.gov/research/catalogIt isn't very useful for searching for ship plans. You can go to the "Contact Us" page and send an email request for information about a specific ship or ship class. Archivists are not ship modelers, and they can't read you mind. There are about 17,000 ship plans in the Archives and they will not search them all to try to find what you want. So you have to be pretty specific and give as much information as you can, such as ship name, hull number, ship class, etc. Tell them you want plans, drawings or blueprints. They have always answered my questions, but expect a delay of up to six weeks before receiving an answer. You aren't the only one asking questions and there are a limited number of Archivists. The Historic Naval Ships Association (HSNA) has a web page for finding information at the National Archives: http://www.hnsa.org/resources/manuals-d ... s-at-nara/HSNA also has a page for searching for ship plans at NARA: http://archive.hnsa.org/doc/nara/searchplans/index.phpPhil

in this shot you can see the stringers. this is a typical cross section. am now trying to find the various deck locations as they are staggered

Joe,
"LL" means long length. Longer than stock lengths.
"Bottom Plating" is that part of the shell plating that is below the water line. The immersed plating from bilge to bilge. "Bilge" is the rounded portion of a vessel's shell which connects the bottom with side.
I would guess the "bottom curve" is the curvature of the hull bottom plating from keel to knuckle, from frames 1 to 7. Aft of that the buttock lines set the curvature.
A "stringer" is a fore and aft girder running along the side of the ship. It makes up the framing of the ship along with the vertical frames. Hull plating is attached to this framing.
The "bottom stringer" rests on the top of the keel. The top of it is straight and probably supported the lowest deck.
A "wing" is the outboard part of a ship. Looks like the "wing stringer" was at the knuckle between the bottom and sides of the boat.
****
I came across an invaluable little book years ago at a used book store - "Ship Structure and Blueprint Reading" by H. L. Heed, printed by the Cornell Maritime Press, New York 1942, 258 pages.
The inner dust cover says "This book is written for the sole purpose of teaching the men who are building the ships to read the prints."
It has chapters describing the parts of ships and how they are drawn in blueprints, a list of abbreviations, and a glossary. It looks like it was the draftsman's bible for ship building in the 1940s. It is small enough (5 1/4" x 7 1/2") to be carried in a large coat pocket.
On many occasions it has helped me to decipher the hieroglyphics embedded in ships blueprints. I keep it on my work desk.
No, I won't consider selling it!

right now I am just trying to figure out the transom set up. I re lofted the hull as i was doing it backwards was why i had several different short lofts. then once i get the transom finished I need to see if I can find how the keel and frames were built
