Define "model"  

.
Ships never disappear from the top down, first off, so that must be your fantasy world, again.
.
First you use a word then demand that someone else defines it?
Why should we be surprised --- flat-earthers most generally get the cart before the horse.
.
You ought to be the one to define model.
.
Then you posted another snow-globe "flat" earth, while you want someone else to define "model" ?

What is with all this arrogance.  You reek of it!  You are so condescending.  Do you really think that God is going to bless this prideful attitude of yours.  Do you think St. Lawrence would approve?  I think not!  

It is disgusting and it is scandalous for Catholics to behave this way.  

[....] this is a photo taken by a submarine while attempting to record a good image of a target ship. They wanted to get the most exposure of the target as possible, and if there were any rogue waves about they would have taken the shot while the target ship was on TOP of the crest with a trough in between the target and the periscope.

A photo taken almost certainly for confirming the identity of the target ship--the more of the hull & superstructure visible--the better.  Especially any unique markings or damage.  If not a prelude to attacking and sinking it, then perhaps just gathering specifics on fleet numbers & movements (e.g., when returning to port with no torpedoes left).  Sometimes it would be just plain foolish for a sub or dive-bomber to hang around to confirm the fate of a target ship that seems to have been hit, so confirmation will be delayed until the next allied sighting (e.g., thro' another sub's periscope).  And some sub-skippers were just more aggressive than others.

[....]  There are hundreds of movies showing periscope images, taken in calm seas, with no erratic waves making things unusual for cherry-picking. [....]  Try watching some WWII submarine movies with moving images of what the periscope showed.

Except that some of the more acclaimed WWII submarine movies were produced during that war, so, e.g., U.S. film crews for Destination Tokyo [×] certainly weren't going to have been able to film on-location in-&-around Tokyo Bay.  So what viewers see on-screen might be the work of a Hollywood special-effects team, often using model subs & ships in water tanks.

Consider instead the submarine footage in the 13 hours of the classic t.v. docuмentary Victory at Sea, which was famous for having been chosen from genuine photographic film made available by the U.S. Navy, including by being captured from the German or Imperial Japanese Navies.[†]

Note ×: A great title for a movie about the daring carrier-launched "Doolittle Raid" (1942), but it was, in fact, a WW-II submarine movie.
