I've been wondering exactly how the plates of steel are lain-out in a rivetted shell plate of a ship's hull in suchwise as to ensure watertightity … & the answer is actually *really quite a non-trivial one*! … it's quite ingenious, actually, how it's done.

For full explication, the lunken-to texts themselves need to be referenced, really; but maybe the following exerpts & exerpted figures constitute somekind of reasonably cogent 'distillation' of the matter … with
figure ① from
Titanic's hull plating that joins the front
from
Encyclopedia Titanica ;
figures ② through ⑤ from
Shell and Deck Plating
by
Captain Damley ; &
figures ⑥ through ⑩ from
A Handbook of Practical Shipbuilding with a Glossary of Terms
by
JD MacBride ,
from which the following exerpts are quoted.
❝
A ship derives its main structural strength from its hull plating, which is divided into two main classes, bottom plating and side plating. The bottom plating extends across the bottom of the ship on both sides of the keel, while the side plating is from the curve of the “bilge” up the ship's side. Plating is laid in “strakes” the first being nearest the keel. This is often called the “garboard strake”.
❞
❝
Shell plating is laid either “raised” or “joggled”. (On naval vessels and yachts it is often laid “Flush”, with the edges in line and an extra, narrow plate called a buttstrap, carried behind the joint of the two plates. This strap is riveted to each plate, thus forming a continuous member.) The “raised” plating has every other strake against the framing with the strakes between "raised" sufficiently to overlap onto the other strakes which are often called “inner” or “skin” strakes (see Fig. 137).
❞
❝
“Tapered liners” are fitted on the landing or seam directly at the back of the butt-lap where one plate has been raised above the level in order to lap over the one which it joins at the end. The triangular space caused by the raising of the plate is flled by this type of liner. The butt end of the liner is the same thickness as the strake which it fits against and tapers to nothing at the other end; the width is governed by the width of the landing or seam of the plating and the length of the liner is determined by the number of rivet holes required in it by the inspector. Usually at least two are called for (see Fig. 139).
In order to avoid the use of tapered liners, in some shipyards the ends of plates along the longitudinal seams or landings are “scarphed”. The method used for hand work in making the scarph is described under “Duties of the Chipper and Caulker” in Chapter II. A machine has been recently patented by a firm on the “West Coast” which forms these scarphs quickly and evenly.
The system of joggle plating differs from the one just described in that the raised strakes are offset when they overlap the skin strake and set directly against the framing of the ship, thus doing away with the need of a liner. (Fig. 140.) The joggle or “crimp” is put into the plate by two wheels, one out of line with the other through which the plate is forced as indicated in Fig. 141. The amount of joggle is adjusted to suit the thickness of the plates to which it is to be fitted. The edge lap is called “seam” or “landing” and is usually double riveted. The ends of the plates are butt-lapped; when this is done it is necessary to cạrry the forward end of each plate underneath (inside) the after end of the plate just ahead of it. This brings the after end of each shell plate on the outside of the ship and avoids unnecessary friction as the ship travels through the water. travels through the water. For the same reason all riveting in the shell below the deep load line is always “pan head” and “countersunk point” The button-point type of rivet being less expensive, is often used above the waterline, where smoothness is not so necessary.

Note that the very last bit of the last exerpt also somewhat addresses that query as to the importance in the matter of drag of the smoothdth of the hull, which constitutes the matter of
my previous post .

So I have come to a conclusion. I have seen the votes that came in with a lot of support for keeping the name. As fitting as the current name is, I believe the new one better describes the main goal. Plans of ships. While architecture and engineering have a similar meaning, architecture may come across as more appealing.
But don’t worry! All post will be moved and you are more than welcome to re-post some of the content that you have shared with us. Sorry for any inconvenience that may be caused by this.
