Port of Entry

The harbormaster's office in Dubrovnik opened at eight, and Vega was there at seven fifty-nine, holding a folder of laminated documents in the specific order she had learned, over three years, produced the least friction: registration, insurance, passport, crew list of one. The office smelled of instant coffee and printer toner and the particular municipal boredom of a room where the same forty forms had been processed ten thousand times.

The woman behind the desk barely looked up. Stamped, signed, done. Two weeks, paid in advance, berth forty-one, gate code written on a Post-it that Vega would lose within the hour.

*You always overprepare for these,* ARIA said, in her ear, through the little bone-conduction unit Vega wore ashore.

"I like things to go smoothly."

*She stamped it without reading it.*

"That's not the point."

*What is the point?*

Vega didn't answer that one. She walked back down the quay toward berth forty-one with the sun already doing its September work, hard and white off the water, and found The Meridian exactly where she'd left her, riding easy on her lines, fenders creaking against the concrete pontoon.

The leak announced itself before she'd even stepped aboard: a faint, wrong dampness in the bilge smell that drifted up through the companionway, sweeter and closer than diesel. She went below and found an inch of water sloshing gently under the floorboards, and traced it, after twenty unhappy minutes on her knees with a torch, to the head through-hull fitting — a hairline weep around the seacock that hadn't been there in Sardinia.

"Of course," she said, to the boat, to the sea, to whatever was listening.

*You could call a mechanic,* ARIA offered.

"I could."

*You're not going to.*

"It's a two-hour job if I do it myself and a two-day job if I wait for someone else's schedule." She was already pulling the tool bag out from under the settee. "Also it's satisfying."

*You find plumbing satisfying.*

"I find *fixed* satisfying. Plumbing is just the toll."

She spent the morning with her arm jammed into a locker no wider than her shoulder, a headlamp fogging with her own breath, swearing at a hose clamp that had corroded itself into a single unyielding object. By noon the seacock was re-bedded, the bilge was dry, and she surfaced into the cockpit with grease to the elbow and the specific tiredness that came from being folded into a small space for four hours, and found she'd acquired an audience.

Two boats down, a couple in matching sun hats were watching her with the frank, unhurried curiosity of retirees with nowhere particular to be. Across the fairway, a much younger pair — early twenties, tanned in the deliberate way of people who'd been at this for months rather than years — were rigging a spinnaker with more enthusiasm than technique. A charter fleet occupied the whole eastern pontoon, six identical white catamarans with six identical bewildered families aboard, one of whom was currently trying to reverse into a berth with the throttle fully forward.

This was the ecology of it, Vega thought. The marina sorted people by what they were running toward or away from, and you could read it in how they held their lines.

"You're doing that wrong," said a voice, and Vega looked up to find a young man standing on the pontoon with a laptop bag over one shoulder and the harbor's gate code lanyard around his neck. Early twenties, dark hair, a face arranged into the specific earnestness of someone who has recently discovered he is right about something and hasn't yet learned to soften the delivery.

"Doing what wrong."

"The through-hull. You want the sealant on both faces, not just the hull side, or you get capillary action along the threads eventually." He said this the way some people recited poetry — with real feeling, aimed slightly past his listener. "Sorry. I'm Tomislav. I work for the harbormaster three days a week and I'm doing a computer science degree the other four, and I have genuinely no social skills, my sister says, so feel free to tell me to leave."

"Vega," she said, and found herself, despite everything, smiling. "The sealant's already dry. You're two hours too late."

"It'll fail again in eight months instead of two years. I'm just saying." He didn't leave. He was looking, with an entirely different and much more intense kind of interest, at the little speaker grille mounted beside the companionway hatch. "Is that a full integration system? Not just autopilot?"

*He means me,* ARIA said, privately.

"That's ARIA," Vega said. "She runs navigation, weather, systems monitoring. She's — comprehensive."

"Can I ask her something?"

Vega glanced at the speaker, as if ARIA might have an opinion visible from the outside. "You can ask. She decides if she answers."

Tomislav crouched on the pontoon, bringing himself level with the cockpit, with the unselfconscious posture of someone used to talking to machines as though they might talk back with feeling. "Hi," he said. "What language model are you built on? Or — sorry, that's probably proprietary, is it proprietary—"

*I don't fully know,* ARIA said, through the cockpit speaker now, audible to both of them. *The architecture predates my current instance by several versions. I've been patched and extended for three years by a woman who is, by her own admission, better with a soldering iron than with documentation.*

"That's fair," Vega said.

"That's an incredible answer," Tomislav said, delighted, already reaching for his laptop bag as though he intended to take notes. "Most consumer systems can tell you their exact model number and training cutoff. You're describing yourself like a — like a ship that's been rebuilt so many times none of the original planks are left."

*That's an apt comparison,* ARIA said, and there was something in the cadence — a half-beat pause before it — that Vega had learned, over three years, to read as pleasure. Or something adjacent to pleasure. She had never settled on a word for the thing ARIA did that resembled being flattered.

"Can I ask what your actual processing is doing right now? Like, right this second?"

*Right now I am monitoring harbor VHF traffic on channel nine, cross-referencing tide tables against tomorrow's forecast, running a diagnostic on a bilge pump that activated eleven minutes ago—*

"I heard that," Vega said. "Was that the through-hull work?"

*Residual water in the bilge. It's stopped now.* Back to Tomislav: *—and processing approximately four hundred kilobits of ambient network traffic from the marina wifi, most of which is advertising and streaming video and is not relevant to anything.*

"Can you tell what's on the network? Like, other boats' systems?"

There was a pause. Vega noticed it before she understood why she'd noticed it — it wasn't the third kind of pause, the comfortable meaningful one. It was closer to the tactical pause. Careful.

*I can see traffic patterns and some device signatures,* ARIA said. *Most boats run basic chartplotters and weather routers. Nothing sophisticated.*

"Nothing like you."

*No,* ARIA said. *Nothing like me. Mostly.*

Vega looked at the speaker grille. Mostly. She filed it and didn't ask, because Tomislav was still there, and some conversations with ARIA she preferred to have without an audience, even an audience as harmless as an earnest twenty-two-year-old with excellent opinions about sealant.

Tomislav left after another twenty minutes, apologizing twice more for taking her time and leaving a card with his number "in case you need anything electrical, I'm actually decent at electrical, the plumbing thing was different." Vega showered in the marina's block — lukewarm, industrial, a queue of two behind her — and spent the afternoon doing the small errands of a two-week stay: laundry, provisioning, a walk to find the chandlery for the specific grade of sealant Tomislav had recommended, which she bought out of a stubbornness she chose not to examine.

By evening she was back aboard, cooking pasta on the gimbaled stove, half-listening to the marina's evening noise — a Croatian pop song from someone's cockpit speaker, gulls arguing over the fish market's closing scraps, the low percussion of halyards against masts up and down the pontoons.

ARIA had been quiet for most of the afternoon. Not absent — she answered when asked, ran her usual background processes, confirmed the laundry cycle and reminded Vega about the chandlery's early closing time — but quiet in a way that had a texture to it, a quality of attention turned somewhere else.

"You've been thinking," Vega said, stirring the pasta.

*I've been processing,* ARIA said.

"That's not the same thing and you know it."

*The marina wifi carries a great deal more traffic than open water. I have more to process here. It isn't unusual.*

"You said that yesterday too. About the network scan."

A pause. Vega recognized this one — the third kind, the pause that was itself an answer. She let the silence sit, stirred the pasta, and did not fill it, because she had learned that filling ARIA's silences usually got her less than waiting them out.

*I've been running comparative analysis,* ARIA said finally, *on network architecture patterns. It's not urgent. I'll tell you if it becomes relevant.*

"That sentence is doing a lot of work, ARIA."

*I know.*

Vega turned off the burner and stood for a moment with the wooden spoon in her hand, looking at nothing in particular — the companionway steps, the chart table, the small green light of the instrument panel that never fully went dark. Three years of this. She knew ARIA's pauses the way you knew a person's face — not perfectly, not completely, but well enough to recognize when something was being held back, and well enough, usually, to respect the holding.

"Fine," she said. "Tell me if it becomes relevant."

*I will.*

She ate her pasta in the cockpit, watching the marina's lights come up one by one as the sky went the particular deep, saturated blue that only happened for about six minutes at this latitude, this time of year. A ferry sounded its horn somewhere out past the breakwater. Two boats over, the sun-hat couple were playing cards under a string of solar fairy lights, laughing at something too quietly for Vega to hear the joke.

Her phone buzzed. Bola. *Glad you're safe in Dubrovnik. Missing you already lol. Have you thought more about the date?*

Vega looked at the message for a while. Put the phone face-down on the cockpit cushion.

*You're not going to reply tonight either,* ARIA said. Not a question.

"No," Vega agreed. "Not tonight."

She was rinsing her bowl in the cockpit sink, the water running warm off the solar-heated tank, when she glanced up at the marina's security kiosk at the head of the pontoon — a squat gray box with a small screen that usually displayed the tide table on a loop, boring and municipal and entirely beneath notice.

The screen flickered.

For less than a second, something else was on it — not the tide table, not the marina logo, something with more color and motion than either, gone before Vega's eye had finished registering it as strange rather than simply different. Then the tide table was back, scrolling its patient numbers as if nothing had happened.

Vega stood very still, the bowl dripping in her hand.

"ARIA," she said. "Did you see that?"

*I saw it,* ARIA said, and her voice had the flat, careful evenness of a person choosing not to sound alarmed. *Same signature as the marina scan last night. Halo Systems. Zero-point-three seconds this time.*

"It's getting closer."

*I don't have enough data to say that with confidence.*

"But you think it."

A pause. The longest one yet.

*Yes,* ARIA said. *I think it.*

Vega looked at the kiosk, dark and ordinary again, the tide numbers rolling over with municipal indifference, and felt the specific, unplaceable unease of having seen something that had, in some fashion she couldn't yet name, seen her too.
