Currently the wreck site is unknown except to them - they’re the ones who discovered it. Eri would (probably) know the proper way to log it - which is only its exact location and depth anyway, perhaps with a few remarks (“lies upright with a slight right list” would be as much as most wrecks have.) But there’s a good chance she can’t do the research needed to figure out what ship may have sank there; having the ship’s name from the wreck would solve that problem.

Logging the wrecksite is something that probably should be done, but won’t actually matter to them - nobody else is ever going to visit it, it’s simply too deep, and even if a diver were to make it down they would never enter. It’s not worth the cost of a submarine or ROV: but on the other hand, a meantime historian or such on the island could be interested in pictures; while he could never afford the the millions the above two would cost, how much would Eri’s dive shop charge for Aya and Chihaya to make a dive or two with a camera? A few hundred, a few thousand at most, and perhaps camera fees. And would Eri give the utterly impossible story its being done by teenage freedivers who visit the wreck for fun already anyway? And what if she was believed… Various plot hooks might lie around here…

And know the other half of the information on the SS Deep. First a few pieces of background information. First, every deck from deck 3 up has two fore and aft corridors running all the way from the forward hold to the aft hold; there is also a staircase on each side fore and aft. Naturally, the port staircase is off the port corridor and such. If there’s some sort of large space for one reason or another, a corridor would probably open into it on each end rather then run past it. There are also a couple of side-to-side corridors on each level, including near both pairs of stairwells. The left side of the ship is intact but burred in the mud of the seafloor up to the top of deck 2; the right side (it’s titled to the right as she rests) is probably burred to the top of deck 3, maybe a little up deck 4.

And yes, those ares an pretty much intact and accessible from higher up.

A few more notes: first, the “key” refers to letters, most of which are inside or next to a box or line of the same color - that box is that area that item would probably be located at, or within, depending on size; lines depend on what the key says. They are also completely separate from and often overlap other items. For example, on page 1 the blue “C” for the forward cargo hold labels the entire blue box as the forward hold, while the green box with the green “D” refers to something else that would be located there without regard for the blue box.

And of course, while a real ship would “probably” be like this, there are doubtless some common areas not shown, and just about anything that would make sense could be inserted where it makes sense. (Amenities would tend to be on deck 6-8; stuff for use of the crew would be on deck 3.

And finally, this is a 3 meter grid; 10 feet for Yanks. (Which is also the deck spacing.) To put ChihAya in context, their -combined- height is around a single square; either of them on their own would only be half as tall as a single square. This is a -big- ship, by their standards. (By the standards of shipping it’s actually a small, entry-level ocean “liner” only suitable for short local low-traffic routes back in the days before airplanes took over.)

Figures.

That was “SS Deep” page 1

Key:
A: The bridge. On each side of it are open air (with solid railing) platforms or areas on deck with doors to the interior center portion. There’s a good chance a small searchlight is or alternately was mounted on each. Inside the bridge is a traditional ship’s wheel (still used in that era, but it’s more likely it was made of wood decay is possible, but then furnishings inside the ship make seem intact so that’s probably not the case), a traditional brass engine room telegraph on one side (optional, it was on its way out when the ship was probably built and this would have been one of the last ship built with one if it had one, but it would certainly look nice) and toward the rear a table for charts (possibly not), a very old fashioned medium size analog radio with plenty of knobs/frequency windows/switches etc, possibly two radios, and the screen (very old design) along with all the electronics for an old radar from the 50’s. Chairs would have been around perhaps the chart table, radios and the radar, but after the sinking could have gone anywhere. There’s likely one or more old-school phone receivers/handsets next to each other, more likely to be towards the back, but no dial; there may be a small switchboard there. (These are used to communicate with other areas of the ship.) A large, horizontal, viewed from the top magnetic compass mounted on something stands might be present; or it might not be. The display for the ship’s gyro compass would be present and be smaller, perhaps a horizontal round gauge perhaps 30 centimeters in diameter mounted on something, it would probably located somewhere be easily visible and readable from somebody operating the ship’s wheel - it’s what they use to know which way to steer! Right behind the bridge is almost certainly room with a chart table (chartroom) and a room with a large number of very bulky even older school radios (radio room).
Something within the range of possibilities listed above for the bridge is very, very likely, higher then the rest of these plans, and would be if this were a real ship. Any finer details I couldn’t say with any useful degree of certainty, and that said I may be wrong on a thing or two, and there may be other things present (indeed there’s a good chance of that). Other things could be there as well. Additionally, A small compartment behind the bridge might contain the equipment for the ship’s gyrocompass (would only be a couple meters wide but would be on the centerline), or that might be in a small compartment low in the ship; or it might be on the bridge itself, or by this point in time it could easily have shrunk enough to not be noticeable and simply be in a cabinet directly under the gyrocompass display.. It’s also pretty likely the captain’s cabin is close behind the bridge, but not with that degree of certainty,

B and B1: these are hatches used for loading cargo. B is slightly open and how our girls entered the ship.

C and C1: cargo hold (rather obviously C1 is aft.) There would a, well, deck every deck to hold cargo.

D and D1: These are “probably” openings under the cargo hatches open all the way to the lowest cargo deck, I have no idea if there was a hatch on each deck as well, but it seems likely, although there might not be. Events is AGVG tend to suggest there are. (After all, they entered through at hatch into the uppermost cargo deck directly above this.) If there was, most hatches would probably be closed, but its possible some might be open to some extent.

E: upper bow area and area under the forecastle (small deck covering a small area at the bow. This area certainly contains at the very least the chain lockers for the anchor chains, probably some other stuff related to anchoring, perhaps storage lockers or rooms for stuff that would be used on the deck or in port, and there’s a good chance a large fresh water tank.

F: Potentially a continuation of whatever the cargo hold or other is aft of it, storage lockers (high change cargo related) could be here and the forward part might be G extending farther back into this space.

G. Forepeak tank. A big tank normally kept empty that water coming though the bow accumulates in. Filled with water today; might actually extend one deck higher then drawn, possibly probably. Long since filled with water. Likely has an access hatch on the top (round, maybe 50-60 cm diameter, secured by being bolted down. It with take tools today to both unbolt it, and overcome the rust in the way. Same for all bolted hatches.).

H. There’s a pretty good change (50-50 or more, or even likely) that diesel fuel tanks fill the red “H” box instead of the lowest deck of the cargo hold. They’d be subdivided into a couple of tanks, as would all the fuel tanks Likely a maintenance hatch (40-60 cm round??) would be firmly bolted in place if it exists. All fuel tanks either are still full of diesel, were being used when the ship sank are have a mix of diesel and very nasty water, or had already been emptied and have highly diesel-contaminated water. In any case going inside would be a bad idea

.
GG1 (red): passenger quarters, staterooms and such,, across all three decks. A small common area or amenity is quite possible; for a common area even probable. Below brown line H1 it would be portholes and the least luxurious cabins; above it would be (larger) square windows for everything. (possibly excluding area J) The highest of the three decks probably contains the mid-range accommodations.

J. The side of the hull here rises to the level of the deck above; there may or may not be superstructure above it. However just behind and inside of the side wall the deck continues though without doors or such (essentially a passage); you can walk directly along the deck along the length of the ship each side.

I. Sort of a promonade on each side; deck (probably no superstructure above), above it, a couple feet tall ship’s hull on the outside, with pillars every couple/several feet. Direct continuation of J; at the aft end the deck continues without a roof.

Note; J and I are already in Savaster’s artwork, which is the main reason they’re here, and would be relatively common in real ships. But many ships might not have them.

K. This is that luxurious common area the girls had a breathhold contest in. Length is roughly correct; the upper of the two decks is just open space for a high ceiling, with no floor or anything.

L (red): these booms ‘would’ be here, at least before she sank, either one on the centerline or one angling toward each side; attached to the mast they effectively served as cranes for loading and unloading cargo. Good chance they’ve fallen away over the years.

L (green): propeller shaft, one each side.

M. there’s a good chance some of the ship’s best staterooms are in this area, an amenity is also possible. The uppermost deck might be narrower then those below in the superstructure here. (In AGVG it was drawn that way.)

N: At the time this ship was built, she would probably have a traditional bow (solid line), but the world was charging over to bulbous bows as standard over the course of the years in which the ship was built. It’s the dashed line. Either way they’re burred in mud below the seafloor and would need to be dug up. There chance of this area ever being in a media here ever is essentially zero.

O: this deck would have no portholes, and before it sank the waterline would be somewhere partly up this deck. Crew quarters, lot of various storerooms for provisions and whatever the crew or passengers would need; and rooms that serve functions such as the ship’s laundry (likely among others along those lines), perhaps some sort of small workshop, and maybe/probably a crew common area, which would be on this deck somewhere.

P: the rudder needs steering gear to move it - this is the compartment that contains it. Likely accessed by a hatch to the cargo hold above; nobody ever really goes here except for maintenance or repairs, but the hatch can be open without tools; or at least it was originally.

Q: masts, per your artwork still standing.

Unfortunately the deck labels ended up on this one. Decks might be numbered or name, from the bottom up or the top down. I also made a few minor changes to the ship to bring it in line with a real vessel.

A: There likely a large dining area here; it wouldn’t fill the entire space. A tiny number of the most luxurious cabins on the ship likely also are around here on this deck. Since it would be high in the superstructure, and since the girls swam directly aft on the deck below, process of elimination puts it here.

B, C, and D and E: Reserved for Savaster eyes only.

Both F1 (red) and F2 (blue) - this ship has either one diesel engine per shaft or two; one might be more likely but two would make the ship more interesting and is probably the better choice. The two F1’s in red are the forward and aft engine rooms; the propeller shafts would not go through the engine’s crankshaft, and instead helical gears perhaps 30 centimeters thick and/or some sort of clutch would connect them. (google “ship reduction gears” to see what they might look like). There would be one diesel engine each side in both rooms, the propeller shafts would continue through the bulkhead into the forward room. Each room would stretch the full width of the ship; it’s possible that there’s a 1-2 meter thick diesel tank between their side walls and the hull. They’re doubtlessly linked by one or two watertight doors in the bulkhead dividing them; those could be either open or closed. Access is by very steep stairs or ladder to a hatch in the floor of the deck above. Various sorts of all other types of machinery would be here; various pumps, importantly the ship electrical generators, etc. The large machinery makes the ceiling two decks above the deck; there is no second level.
In the event of one diesel per shaft there would only be a single engine room, taking up roughly the space F2 (blue) (longer to provide space for all the other various stuff.) Otherwise the same applies.

SS Deep page 2 key continued (as was the last post):

G1 and G2: Savaster’s eyes only.

H. All fuel tanks; subdivided into plenty of smaller tanks of course. All fuel tanks would have “manholes” at the top securely bolted in place for maintenance access; all of these in the entire ship would be securely closed, and the girls are going to need to bring down some tools to get them open even when they were new, rust has likely made things worse. And as always, this is a VERY bad idea.

J and JJ: a ship this size would have multiple watertight compartments, with watertight doors on each corridor (the left and right one pretty much) that passed through them; orange lines show where the bulkheads would be. Depending on the manor of sinking; those in bulkheads marked JJ may be closed, or at least more likely to be. (the one at the aft end of the forward hold on deck 5, at least on the right side, was how the girls headed deeper into the ship in AGVG, so at least that is open). This could be to try to save the ship, or simply since those are also the doors and to keep passengers from wandering into the holds on a routine basis. Those simply marked “J” likely would have most or all of their doors opened to facilitate abandoning ship. The doors could certainly be operated manually, operation remotely would be electrical but if the generators went down with the engines that wouldn’t have worked. Those in the passenger and crew areas would normally be open.

But really, ignore all that. Every time there’s a door take your pick - open, partly open, closed but can still be opened manually, or jammed or rusted shut and not going to open. Probably most but not all of them open works best for any given story. Just know there ‘is’ door here that could be closed, although many of the ship’s passengers on her glory days would have hardly noticed them, save for something a couple centimeters high to step over.

In AGVG, after heading through an open door on ‘deck 5’ the girls then went to either the port or starboard stairwell (I have a hunch it’s starboard) to the deck labeled ‘deck 7’ then headed aft to the fancy common area where they all had their breatholding contest. This is a rather large distance when you take doubling back on the stairs and likely some minor lateral movement into account; this ship can take a rather lengthy amount of time to swim through - be sure you leave yourself not only enough time to get to the surface, but also to exit the ship! The watertight bulkheads don’t extend above deck 5.

K: double bottom, 40-60 cm deep, also runs all the way to the stern (not shown). Likely subdivided to some degree. Only relevant in that the engine rooms likely have small “manholes” to them that have a considerable number of fasteners around the edge, but that were designed to be turned without tools. (likely since rusted in place.) If any part of the wreck would be damaged from hitting the seafloor it would be these first. The girls could fit in them without touching the top or bottom but swimming would be very cramped. Basically irrelevant, but better that they exist in the highly unlikely event they would be useful for one thing or another down the road then not exist at all.

L: not a space, rather the double bottom continues along under H and L; additionally the bottom of the hull under H and L is V-shaped.

M: Anywhere in this area not containing a common area or amenity (whether specified on these drawings or not - it’s likely there’s more that aren’t) likely contains medium-end passenger quarters on the lower two decks and high-end on the uppermost. On these decks square windows are the norm.

N. mast collapsed per your artwork. The radar antenna used to be mounted on top of it; who knows where it is now; still attached, broken, laying on the deck or simply missing.

O: the diesel exhaust likely travels up through here to the funnel through a narrow area along the center of the ship.

P: Any real ship would absolutely “not” have any sort of large crane here, in the event that area gets drawn again.

Q: there would be maybe 2-3 cable drums both here and on the deck above the aft hold near the end of the superstructure, but they wouldn’t be more then a meter or two high.

R: this ship doesn’t have railings, instead the edge of the hull extends above deck level by about the same amount. The dashed line here and farther aft on deck 6 show roughly where the edge of the hull would be.

A bunch of the things here are almost certainly never to be relevant in the slightest. But anything that isn’t known about can’t be used at all, so I’ve tended toward toward including it on the remote chance it might matter someday. There was also a choice not to go into fine detail, more then “about here” or “this is what types of things would be here,” Also - the passenger and (to a lesser extent) crew spaces wouldn’t have bare metal walls, they’d be finished with ‘something’ and certainly painted, or decorated some other way. Finally, this looks more or less exactly like what a real ship might look like; a few minor changes were made from the two decent drawings in AGVG.

Edit: decks would be numbered or “lettered,” not named. Oops…

Oh - this ship wouldn’t have a crow’s nest; those had gone away decades before she built.

I’d also like to say there’s a combined ChihAya diving profile that doesn’t depend on times at all, and works equally well at any point in the series under the circumstances where it might be needed.

Essentially, it’s for cases when you need to get one of as much time/distance/depth/air/whatever underwater for some reason, both Chihaya and Aya don’t need to be there, just one of them, and it’s beyond what either Chihaya or Aya are capable of on their own. The most likely reason would be for a rescue of some sort.

Essentially, Chihaya and Aya start together, and at a point which Chihaya (who can’t swim as far or long) has used about 1/3rd of her air/etc., she transfers another third to Aya, then returns to the surface. Now after having traveled a third as far as Chihaya could, Aya is now fully topped off, and has her full ability starting from this point. Aya goes and does whatever the reason for this was, turns around and heads back, while Chihaya, with lungs refilled with fresh air, dives back down to meet Aya where she did the first time, again a third of what she can do from the surface, refills Aya with a third of her air (Aya’s nearly out at this point), and they both head back to the surface, and reach it together at about their (now changed) maximum dive limits.

This means Aya gets both her own ability and either 1/3rd of Chihaya’s max added on top (if counting distance/etc. away from the surface) or 2/3rds (if counting time or counting total covered distance).

Mostly this would be used for situations such as rescuing somebody; I’d note Saski might be willing to “do “X” or die trying,” but if Chihaya and Aya are standing by they might not let her die trying. Aya may or may not be able to do it either, but using this profile ChihAya together can certainly have Aya + 2/3rds Chihaya drag Saski out of whatever mess she may get herself into.

Alternately if for whatever reason they need to send “somebody” to maybe -400 meters briefly, then could probably send Aya there for maybe a minute or three. Maybe somebody asked Eri if she could get pictures of something that deep; the camera would make coming back up slower though. (Tying the camera to a line with the other end on the boat might enable it being pulled up from the surface afterward, who knows.) Or who knows what else.

The only higher performing combination possible is the (rather unlikely) Aya + Saki (either way, they’re both roughly equal), but that’s only a minor increase. Chinaya is at least 75% of Aya, perhaps a little more; by default that also makes her at least 75% of Saski, and that benefit only applies to the 1/3rd top up/refil. This roughly means a ChihAya version of this profile would be either 125% (distance from surface) or 150% (time/air/total distance) of Aya alone; replacing Chihaya with Saski would only increase it to 133% or 167% (depending on what you’re measuring of Aya alone. (And I suspect Saski has much less experience with air transfers (has she even ever given one? I wouldn’t know), while for ChihAya it’s normal by now, and while ChihAya might be able to do it with negligible air loss by now, Saski might lose enough bubbles in the transfer to eat away most, maybe even all the tiny increase. (25% lost in the transfer would remove any benefit. Using both Chihaya and either Aya or Saski together makes no difference, since on the way down Aya/Saski doesn’t have any more room for air in the first place, having not used enough up, while on the way back while on the way back one of them alone has enough air to allow Aya/Saski to reach the surface.

Either combination is about the most you’ll get out out of the 5 Minute Summer universe; going any farther would require three links of divers, and while it’s been a long time since I’ve crunched any numbers, you’d need at least 3 more divers, possibly 4 or more to make it work; each addition link might need -at least- double the number of divers as those below, the benefits IIRC per additional link starts going down -fast-, they’d all need to be divers not too much worse then Chihaya for it to actually matter and experienced with air transfers, and Aya, Saski and Chihaya combined don’t really work well together in this configuration.
