hard.â
âAnswer the question.â
âOh, all right. Itâs forward in the bulb nose; first thirty-two feet.â
âWhy?â
âBecause of the teardrop shape of this class, and for balance. The nose gives the most room for shielding.â
âHow thick is the radiation wall behind the pile room?â
âI missed that.â
âTwelve feet. Remember it. Twelve feet.â
âWell, I can tell you what itâs made of: hafnium, lead, graphite, and poroucene.â
âWhatâs on the aft face of the radiation wall?â
âDirect-reading gauges for the reactor. Repeaters are in
the control room, forward bulkhead to the right of the first-level catwalk. Then there are lockers for ABG suits, tool lockers, doors to the tunnels leading into the pile room.â
âYouâre getting it. How many tunnels into the pile room?â
âFour. Two top; two bottom. Not to be entered for more than twelve minutes at a time unless wearing an ABG suit.â
âFine. Whatâs the rated horsepower?â
âTwo hundred and seventy-three thousand, reduced to about two hundred and sixty thousand by the silencer planes behind the screw.â
âExcellent! How long is the engine room?â
âUh ⦠nope. That oneâs gone, too.â
âLook, Ramsey, these are important. You have to remember these distances. You have to get a feeling for them. What if you donât have any lights?â
âOkay. Okay. How long is the damned thing?â
âTwenty-two feet. It fills the whole midship section. The four electric engines are set two to a level with the gearbox for the drive below center aft.â
âGotcha. Here, let me take a flash of the aft section. Okay. Now try me.â
âHow many catwalks in the engine room and where located?â
âLook, I just flashed the aft section.â
âHow many catwalks andââ
âOkaaaay. Letâs see: one center of the control deck going forward. One off center into machine stores on the second level below. One called A level into top stores. Same for bottom level: called B level. Short bridging catwalks
from A and B levels to the engines and oxy tanks. And one very short to the conning-tower-retracted which lifts into a section of steps when the tower is extended.â
âGood. You see, you can do this if you set your mind to it. Now, tell me how the four staterooms are placed.â
âStaterooms yet.â
âStop dodging the question.â
âWise guy! Letâs see: captain is top-level starboard behind the electronics shack. First officer portside behind the recreation room-sick bay. Engineering officer starboard below the captainâs quarters and behind the machine shop. Electronics officer portside below the first officer and aft of galley stores. Thatâs the place for me. Gonna cut me a private door into galley stores.â
âWhereâs the galley?â
âThat one I can answer. Itâs far port, top level, entered through the wardroom. Selector controls for the prepackaged meals are against the bulkhead separating galley and wardroom. The galley-wardroom unit is between control deck and rec room.â
âWhatâs behind the staterooms?â
âMachinery of the Palmer induction drive.â
âWhy an induction drive?â
âBecause at the dive limit for Hell Divers, there can be no weak points in the hull, therefore no shaft through the hull.â
âYouâre getting the drive on the hypnophone tonight. Every man blindfolded. Thereâll be a model for you to work on day after tomorrow.â
âOh goody!â
âWhatâs the pressure hull limit for Hell Divers?â
âThree thousand and ten pounds to the square inch or 7000 feet.â
âStick to your first answer. Pressure varies with different water conditions. Youâd be okay at 7100 feet in one place, dead at
