Civilian bulk hauler

MV Tallow

A hauler whose articles are forty-one years old, that went out with ten and came back with fourteen. Her acting Master's hand log says three hundred and thirty-one days on passage. Her master clock says two hundred and forty-one. Her second engineer's says two hundred and sixty. Nobody has ever reconciled them, and the ship is the argument. What the Cairn found inside her was order: the walking line worn to bright metal on the mess deck, every locker labelled twice, a cloth on the table, and three hundred and thirty-one strokes cut into the paint beside the galley hatch.

The Cairn
Drawn as
As she came alongside at the Cairn's quarantine berth on Day 4 of 2318 — displaced, overdue, and carrying more than her manifest. The SITE sheet carries her whole life after that as dated revisions: the short-haul years out of the Cairn, the ground at Threap in 2334, the Mireth load-out, and the eleven days of 2342 that brought her back down at the stern with two hundred aboard.

Bare metal for a metre and a half above the line where the paint should have been; above that the whole flank matte and micro-pitted, the way a hull looks after a season working a dusty system. After end of the main hold — the cargo office is the steel box off it, one deck up. Cargo port, ramp and gangway platform, on the flank at the number-two hold. The aft cargo seam above it carries a repair strap welded down by hand, badly, in a hurry, and painted. Midships lock — the isolation sleeve; the umbilical mast and four braided lines up into the flank. Ten of the fourteen came off here. The galley hatch. 331 strokes in fives in the paint of the frame beside it, from the deckhead down past the second locker — twenty-two of them shallower, in another hand. The mess ports. At the third, a woman with a baby up on her shoulder, her free hand going up as the tender's lamps came across. Sleeping deck rigged aft, where the plating stays warmest. Mast lights — number two dead. One work light at the spine when the refit crew started on her. The after trunk — the berth feed's air and power come in here. 'Running cold to save the umbilicals, and the crew were wearing their whole wardrobes.' Heat map: the reactor and the reclaim plant reject their heat through the after plating — warm aft, cold everywhere the umbilicals allowed. 1 20 40 60 80 100 120 140 160 180 200 220 240 260 280 300 320 340 360 380 400 FRAME

  1. 1-01 Ladder well (head) Fr 182–192 published Who the Door Admits, chapter 14 — 'Efe came in from the ladder well with a rolled schematic under her arm'; ch14:89; ch20:65,:111

    The one vertically-confirmed stack on the ship: ladder well → cargo office → tween-deck → hold. Its head is drawn here; its foot is in the main hold.

  2. 1-02 Crew berths (designed) Fr 226–300 fixed spec ruling 2026-09-21; The Way Out Closes, chapter 9 — 'every one of the nine had a berth and a berth's worth of water'

    Berths exist; nobody's door is ever placed. On the passage the crew slept aft instead, on the rigged deck (2-08). The 2334 sleeping list hung 'on its nail' at a frame near the boat bay (The Way Out Closes, chapter 9) — a later arrangement, not this one.

  3. 1-03 Bridge Fr 300–350 published Who the Door Admits, chapter 18 ('the galley's clock and the bridge's clock months out from each other'); ch20:77 ('Corin's after that, when I was on the bridge'); ch06:27 ('My helm's been correcting to that wake for two days'); ch22:191 ('one deck up from her own dying air')

    The space is published; its position is the drawing's — a bulk hull with her machinery aft carries the bridge aft over the accommodation, and that puts it one deck up from the mess deck as the prose has it. Helm; the bridge clock, months out from the galley's. A 'second' stands watches here by 2342 (Inside the Window, chapter 8).

  4. 1-04 Chart space Fr 350–370 fixed spec ruling 2026-08-01; published by 2342 — Inside the Window, chapter 8 ('Sleep happened at the chart table'),:35 ('In the chart room Ravn wrote the hour')

    Not mentioned in 2318; a chart table and a chart room are on the page in 2342. Drawn from the first because nothing says it was added.

  5. 1-05 Master's cabin Fr 370–390 derived Master Cray, Who the Door Admits; never drawn

    Canon establishes a Master who died aboard and an acting Master who took her in; it does not draw the room. Efe keeps her own book in her jacket (Who the Door Admits, chapter 9,:175) and by 2342 sleeps at the chart table.

  6. 1-06 Stern watch Fr 390–410 published Who the Door Admits, chapter 5 — 'a stern-watch rating carried her in and stood at Lote's shoulder'; ch05:157 (the rating who kept the count by hand for seventy-one days)

    The watch exists; its station is the drawing's. The rating who stood it kept the only hand tally aboard that was argued about at the time.

Grade of every figure on these sheets

  • published Stated in the books. If a drawing disagrees, the drawing is wrong.
  • derived Arithmetic on published facts; the working is given.
  • fixed Canon was silent here and the drawing decided.

Principal figures

Each figure carries its grade: published (the books state it), derived (arithmetic on what they state) or fixed (the sheet's own decision, bounded by what the books rule out).

  • Length overall

    204.5 m

    derived410 frames @ 500 mm

    Length is not published. It follows from the beam at a bulk hauler's proportions and from eleven hold bays; the frame run is the drawing's, and it is the drawing's so that the published eleven-metre run between the cargo office and the crew mess (Who the Door Admits, chapter 14) can be arithmetic rather than assertion. Bounds the prose does give: the number-two hold is at least twelve metres inside (Who the Door Admits, chapter 6); the cold store is forty metres from the apron bollard at the sleeve (Who the Door Admits, chapter 9); ISV Rampart carries scrubber substrate 'for a hull twice the Tallow's size' (Who the Door Admits, chapter 7); she lies against eighty metres of apron at Nine (Who the Door Admits, chapter 4).

  • Beam

    41 m

    publishedWho the Door Admits, chapter 6 — 'The registry gave the Tallow a beam of forty-one metres across the frames. Wells laid the graticule across the hull on the optics, read the angle off the reticle, and worked the range with a pencil on the back of a stowage card.'

    The registry figure, and the one the throat-side pilot used to range her by eye when the boards would not agree. It is the only dimension of this ship canon states outright.

  • Height

    21.2 m

    derivedfive decks, floor heights below

  • Hull age

    41 yr

    publishedWho the Door Admits, chapter 5 — 'the Tallow's articles were forty-one years old under a registry that still existed'

    Read as the registry age of the hull. The line says articles; the sheet says so rather than improve on it.

  • Complement

    10 out, 14 back

    publishedWho the Door Admits, chapter 3–75 — 'Ten out. Fourteen aboard. Nine of the ten. One born.'

    Nine crew, four Sethlan passengers taken up at the depot, one child born on ship's day 168. Master Cray died aboard on ship's day 88 (Who the Door Admits, chapter 20); Efe brought her in as acting Master, two hundred and forty-three days of command (Who the Door Admits, chapter 20).

Systems

Water plant and scrubbers

published

Three barrier stacks, thirty cartridges baked four times

Three barrier stacks crazed through the potting. 'Your scrubber beds have done eleven months. Your barrier seals were certified for a year and have done a year. Your membranes are past service life and three of them are past it by a margin that should have killed somebody.' (ch06:111). Four full changes of scrubber media on a run that does not change one, the used beds retained aboard by mass (ch03:99). Grey holding 84 % → 91 %; independent reserve nineteen hours against seventy-two required (ch18:31). Whatever the passage actually was, this is the equipment that had to keep working through it.

  • Barrier stacks3 — crazed, weeping at the ends, failed leak-check
  • Scrubber cartridges30 in the ship's bins, each baked four times (trade allows two)
  • Grey holding, Day 1191 %

Who the Door Admits, chapter 18; ch06:111; ch09:13; ch03:99; ch18:23–31

Main plant

published

Reactor; single plasma main engine; helm

A reactor, dumped to standby when the umbilicals took her (ch06:87) and read by the Warden in its log (ch06:107); one main engine that leaves 'a good clean plume signature, plasma temperatures' (ch06:21); a helm that corrected to a displaced wake for two days (ch06:27). Type and thrust are never given. Landing legs appear in 2334 — 'Tallow sat on her legs with her lamps off' (The Way Out Closes, chapter 8) — and are on the site sheet as Rev E; whether she always had them is open.

  • Route rating, the return leg9 hours 12 minutes 'had been rated at nine hours and twelve minutes since the throat was first surveyed'

Three clocks

published

331 / 241 / 260 — and none of them the Cairn's

'Three hundred and thirty-one days. That's my book, kept by hand. The ship's master clock came home saying two hundred and forty-one. My second engineer counted two hundred and sixty and will argue with either of us. Your Warden has all three.' (ch18:55). 'The galley's clock and the bridge's clock months out from each other and both of them months out from the Cairn's' (ch18:9). The station calendar has her six days dark on a nine-hour road (ch06:63). The sheet draws three clock faces — bridge, plant, galley hatch — and does not add them up.

  • Elapsed, hand log331 days
  • Elapsed, master clock241 days
  • Elapsed, second engineer's260 days
  • Elapsed, station calendar~6 days dark

Cargo

published

Eleven bays, a tween-deck, and a number-two hold at temperature

Manifested: 31 sealed transit cradles in six crates, 40 litres each, hazard class two, in the number-two hold on a four-line cradle bus that ran continuously for the whole count; plus 4,800 kg of bulk print feedstock (consignment nine), eaten. She came alongside eleven tonnes light against her declared mass 'and her cargo lines all read present and correct, so the eleven tonnes isn't cargo' (ch02:228) – Sould works it as what nine bodies lose over three hundred and thirty-one days (ch02:234). Her own cargo gear appears on the page in 2336 (The Road Called Good, chapter 28).

  • Transit cradles31 in 6 crates, 40 L each, class two
  • Cradle bus4 lines, continuous for the whole count
  • Mass return11 tonnes under declared

Berth fit

published

Four braided lines, a mast, a sleeve, a pass-through

'The Tallow's umbilicals ran up into her flank in four braided lines' (ch09:193). Air on at eleven, power at eleven ten; the reactor to standby (ch06:87). 'Two hands in suits on the outboard umbilical at the mast — the port release won't answer remotely and hasn't since the crossing' (ch22:189). Substrate passed through 'her sleeve' (ch07:73); water cans through a pass-through 'built for sample crates', two at a time (ch18:5). The after trunk is what the feed warms (ch14:29).

Who the Door Admits, chapter 9; ch22:189; ch07:73; ch18:5; ch06:85–87

Set, transponder and mast

published

One set; a beacon; the mast lights

Transponder block 'hull ID good, authentication good' with an elapsed counter reading 331 days (ch02:222); 'We have a beacon up.' (ch06:17). Her own set transmits from the mast (Inside the Window, chapter 5). Mast lights, plural (ch24:69); number two dead at the print date (ch06:53). No radio room is ever placed — none is drawn.

Who the Door Admits, chapter 2; ch06:17,:53; ch24:69; Inside the Window, chapter 5, ch08:3

What was checked

The books state distances aboard this ship. The drawing has to produce the same ones or it is wrong — so it is made to, and the working is shown. These run again on every build; a compartment moved by a metre fails them.

  • “The crew mess is eleven metres aft of the cargo office” Who the Door Admits, chapter 14 ('a mother eleven metres aft', said in the cargo office), ch14:53 (Lote in the crew mess)

    2-01 cargo office ends F204; 2-06 crew mess begins F226. 22 frames at 500 mm = 11.0 m, and the mess is at the higher frame number, i.e. aft. Corrected 2026-09-21 from a sheet that had the mess forward of the office. Pass.

  • “The cargo office is off the after end of the hold” Who the Door Admits, chapter 14

    The main hold 4-01–4-04 ends at F180 on D4; the cargo office 2-01 begins at F182 on D2, over the hold's after bulkhead, with the ladder well 2-02 beside it dropping through the tween-deck to the hold (ch14:27; ch20:65). The 'after end of the hold' annotation sits at F181, under the office. Pass.

  • “The eleven metres is the midships lock” Who the Door Admits, chapter 9–99 (through the lock, Sesk is on the mess deck); ch22:191

    2-03 midships lock spans [204, 226] — exactly the run between the office's after end and the mess's forward bulkhead. 22 frames at 500 mm = 11.0 m. The lock opens aft onto the mess deck as the prose has it. Pass.

  • “The number-two hold is at least twelve metres long — the Master lay twelve metres from the cradles” Who the Door Admits, chapter 6; ch06:99

    4-05 spans [182, 214]. 32 frames at 500 mm = 16.0 m. Crates drawn at the forward end, the remains at the after end. Holds.

  • “The third locker is forty metres from the apron bollard at the sleeve” Who the Door Admits, chapter 9

    From the lock's after edge F226 to the cold store's after end F270: 44 frames at 500 mm = 22.0 m horizontal, plus three deck drops (D2 z 14.8 to D5 z 0.0) and the sleeve's own length. Under forty from the bollard. Pass.

  • “The passage runs aft from the mess to the sleeping deck and the machinery” Who the Door Admits, chapter 9,:179; ch09:121

    2-06 mess ends F260; 2-07 passage spans [260, 300]; 2-09 sleeping deck spans [300, 340] and abuts the machinery casing 2-10 at F340, over the engine room 5-06 [340, 396]. Pass.

  • “Efe speaks from one deck up from the mess deck's air” Who the Door Admits, chapter 22

    D2 (mess deck) z 14.8 + height 3.4 = 18.2; D1 (bridge deck) z 18.2. One deck, no invented deck between. Corrected 2026-09-21 from a six-deck sheet with a boat deck the book never mentions. Pass.

  • “Beam is forty-one metres across the frames” Who the Door Admits, chapter 6

    Stated dimension; carried into the drawing unaltered and used to scale every deck plan. The passage 2-07 at band ±0.04 is 3.3 m wide on it.

  • “Two openings from 2318 — a personnel lock midships and a cargo port with a ramp” Who the Door Admits, chapter 9 (the lock); ch14:225 (the ramp); ch22:193 (the cargo hatch, the Sethlan cradle out of it); ch22:183 (the gangway platform)

    2-03 midships lock [204, 226] on D2; the cargo port annotation at F200 on the hold flank at 4-05. Distinct openings, distinct chapters. By 2342 only the after port works (Inside the Window, chapter 8) — a revision line, not a change to the print. Pass.

  • “The strap and the doubler are two repairs, twenty-four years apart” Who the Door Admits, chapter 6 (strap, painted, 2318); What the Station Keeps, chapter 6 (doubler, unpainted, 2342); Inside the Window, chapter 8

    The print carries the painted strap over the aft cargo seam at F200 and nothing else on the after-quarter plating. The unpainted doubler and the frames standing through the plating are Rev G on the site sheet. Pass.

  • “No compartment on this sheet carries a grade its line cannot bear”

    Removed: 'Ship's office' and 'Radio and log space' (the hand log is in Efe's jacket, ch09:129,:175; the ship's log is in the cargo-office locker, ch14:27,:71) and a boat deck to hold them; three tween-deck subdivisions with no line. Regraded: crew berths fixed; chart space fixed (published only by 2342); the bridge's position fixed, its existence published. Pass.
