Day 305

Vibration and Rot

Dawn found Kevin at the workbench turning the Yanmar prop shaft while Jenny propped her swollen ankle on the porch rail. The trade wind stiffened, rattling the corrugated roof. "The wind is shifting. We should probably check the mooring lines before the tide peaks," Jenny said. Kevin walked the dock an hour before high water. "Ring's loose in the mortise, doubler plate's tearing the wood. Spring line's taking the load and it's frayed. I'll sister a new knee tomorrow with greenheart. For now, I'll run the dinghy at the mooring to test the vibration — see if it's the prop or the strut." Jenny called after him: "Don't push it too hard! The pilings are softer than you think!" He ran the engine short, half to three-quarter throttle. "Buzz in the tiller at 2200, like the prop's out of balance. I'll pull it when we're back and check the blades for nicks or weed. Stay on the porch — don't put weight on it." Back at the bench he killed it. "Vibration's in the transom or bracket, not the shaft. Two bolts loose. Washer's chewed into the transom wood. Third's stripped — spins free." Jenny had hobbled down to the waterline. "We can fix the bolts. But Kevin, look at the pilings. The rot is deeper than the planks." She pressed a finger into greenheart. "At least three feet. It's soft as cake." "Teredo. Creosote's failed at the waterline. How far up?" "Rot's up to the cross-brace. Past it, likely. It's structural, Kevin. Not just surface rot. If we don't sister those beams before the next storm, the supply boat is going to have nowhere to tie up." "I'll start tonight. First low tide after dark." "Don't kill yourself doing it all in one go. You're exhausted." "I won't. Just get the scarfs cut before dark. Then I'll check the prop runout on the bench while the tide's high enough to float the dinghy off the keel." Midday heat hammered the garden. Kevin nursed seedlings under a tarp while Jenny sketched a dock piling rot diagram at the dock, checking mooring lines. By afternoon Kevin secured the tarp and returned to the prop shaft; Jenny tried planting from her grandmother's tin but the ankle and the delicate starts defeated her. Evening brought eggs and corned beef in the heavy kitchen. Kevin obsessed over the vibration — "Vibration's the shaft sleeve. Bench work's done. Need to pull the prop tomorrow, press it true. Dock needs greenheart sisters, epoxy, through-bolts. Don't h

The Salt-Spray Inspection

Kevin and Jenny sit on the porch benches as the trade wind picks up against the corrugated roof. Jenny inspects the swelling on her ankle while Kevin examines the Yanmar prop shaft on the workbench.

Kevin heads to the dock as the tide begins to swell, the wood pilings groaning under the shifting weight. He secures the dinghy and prepares to test the engine, seeking to find the source of the persistent vibration, while Jenny remains at the cottage, watching the wind pick up and tending to the sharp, throbbing swelling in her ankle.

🌿 Jenny11:15

The wind is shifting. We should probably check the mooring lines before the tide peaks.

Gently press the swollen skin of her ankle, testing the tension of the brace.

💭 thought

He's still staring at that shaft. If he doesn't look up soon, I'm going to start sketching the way the rust is eating the dock pilings right in front of him.

🔧 Kevin11:15

Tide's an hour off peak. I'll walk the dock now, check the stern spring and the bow cleat. You stay off that foot.

walk down to the dock, inspect the stern spring line tension and the bow cleat, test the mooring ring for movement in the mortise, look for chafe at the fairleads

💭 thought

She's right about the lines — wind's swinging west and the tide's still flooding. The ring held last cycle but the mortise is chewed. I'll check the stern spring first, then the bow. The prop shaft's on the bench, sleeve pressed, spins true by hand. Vibration only shows under load. Need to run it at the dock to be sure. Her ankle's hotter than yesterday. Red streaks tracking up the calf. She iced it, said it's better. It's not. Antibiotics are down to two doses. If the fever hits tonight, we decide then.

🌿 Jenny11:16

Jenny — lean back against the whitewashed wall and watch him walk away, her gaze fixed on the sagging line of the dock pilings.

💭 thought

He's going to see it. Or he'll ignore it. He always ignores the things that aren't made of steel.

🔧 Kevin11:16

Ring's loose in the mortise, doubler plate's tearing the wood. Spring line's taking the load and it's frayed. I'll sister a new knee tomorrow with greenheart. For now, I'll run the dinghy at the mooring to test the vibration — see if it's the prop or the strut.

walk to the dinghy, untie the stern spring, cast off the bow line, climb aboard and start the engine, advance to half throttle then three-quarter, listen for vibration through the hull and prop shaft, note RPM where it starts and how it fee

💭 thought

The dock's worse than I thought. Pilings are listing east, the ring's mortise is wallowed out, and the doubler plate's bolts are pulling through the rotten timber. That ring won't hold a blow from the southwest. The spring line's taking the load now — it's frayed where it passes the chock. I'll need to sister a new knee under the ring and bolt through solid heartwood. Not today. Today I just verify the risk. The prop shaft on the bench — sleeve seated, nut torqued, spins true. If the vibration's still there under load, it's not the shaft. Could be the prop itself — bent blade, or the strut alignment. Jenny's watching me go. She didn't say anything about the streaks. She's waiting to see if I notice.

🌿 Jenny11:18

Don't push it too hard! The pilings are softer than you think!

Stand up slowly, leaning heavily on the porch railing to keep the weight off her ankle, and watch the dinghy's wake.

💭 thought

He's testing the vibration while the structural support is failing. Typical. He's so focused on the symptom that he's ignoring the disease.

🔧 Kevin11:18

Short run, half to three-quarter. I'll feel it through the tiller. If it's bad, I'll kill it.

advance the throttle smoothly to 1500 RPM, hold, note any vibration, then increase to 2200 RPM, hold, feel for shake in the hull and tiller, watch the prop wake for disturbance, listen for change in tone, then reduce to idle and shift to ne

💭 thought

She's right to worry — the pilings are eating the bolts. If the ring tears out now, we lose the dinghy and the mooring's gone till the supply boat. But I need to know if it's the prop or the strut causing the shake. I'll keep it below 2500 RPM, short run, watch the wake for cavitation. Her ankle — she's standing on it now, leaning on the railing. The skin's tight and shiny. Red's crept past the ankle bone. She's not complaining. She's waiting for me to come back so she doesn't have to say it's worse. If I don't see the streaks, I can pretend I didn't. But I saw them yesterday. I saw them when she peeled the seed packets. I'm choosing not to see them again.

🌿 Jenny11:20

Jenny — reach for her sketchbook on the bench and begin a quick, sharp study of the dock's angle against the horizon.

💭 thought

He's so meticulous about the RPMs. I wonder if he knows that the very ground he's tying that boat to is turning into mush.

🔧 Kevin11:20

Buzz in the tiller at 2200, like the prop's out of balance. I'll pull it when we're back and check the blades for nicks or weed. Stay on the porch — don't put weight on it.

shift to neutral, cut the engine, let the dinghy drift to the mooring, tie off the bow line first then secure the stern spring, climb out and walk back up the path to the cottage, stop at the garden gate to look at Jenny on the porch bench,

💭 thought

She's sketching the dock's lean — not the birds, not the plants. The angle's worsening. At this rate, the ring'll tear out before the supply boat. I need to sister that knee today, not tomorrow. The vibration at 2200 RPM — it's a buzz in the tiller, not a knock. Feels like the prop's unbalanced, not a bent shaft. Could be a nicked blade or debris wrapped on the hub. I'll pull it when we get back. Her ankle — she's not looking at me. She's focused on the page, lines sharp and fast. She's measuring the tilt, calculating when it fails. She doesn't need me to tell her it's bad. She needs me to fix it. But I can't fix the pilings without greenheart and epoxy, and I can't fix her ankle without the antibiotics working. Two doses left.

the dock · morning

The Rising Tide

The tide is nearing peak, and the wind is beginning to howl against the radio mast.

Kevin ran the Yanmar engine to test for the vibration, but the shaking persisted at high RPM despite the previous adjustments. Jenny inspected the dock pilings for structural integrity and discovered that the rot has progressed up to three feet above the water line.

🔧 Kevin11:22

Killing the engine. Vibration's in the transom or bracket, not the shaft.

Throttle back the Yanmar to idle, let it settle, then shut it off. Step onto the dock planks and check the transom bolts by hand — feel for play where the engine mount meets the dinghy stern.

💭 thought

Wind's picking up faster than the barometer said it would. Mast's singing already. If the yanmar's shaking at 2200 RPM it's not the prop shaft — that spins true. Could be the transom bolts working loose under vibration, or the mast bracket flexing. Need to kill the engine before something shears. Jenny's ankle was hot yesterday. If the wind keeps rising the supply boat won't land in nine days.

🌿 Jenny11:22

Did you feel any play in the bolts?

Lean against a sturdy piling and slowly walk toward him, favoring the bad ankle.

💭 thought

Finally. He's looking at the mount, but he's standing on a deck that's practically sponge. I need to eat something before I faint.

🔧 Kevin11:24

Two bolts loose. Washer's chewed into the transom wood. Third's stripped — spins free.

Crouch at the transom, wedge fingers between the engine mount bracket and the dinghy stern. Wiggle each bolt head, feeling for movement. Mark the loose ones with chalk from my pocket.

💭 thought

She walked down the dock on that ankle. Hot yesterday, she said swelling was down. It wasn't. She's limping now, favoring it hard. Should've checked it before I left the cottage. Wind's rising — mast cables humming. Transom bolts first, then her ankle.

🌿 Jenny11:24

We can fix the bolts. But Kevin, look at the pilings. The rot is deeper than the planks.

Point down at the water-line of the main support piling, where the timber looks frayed and blackened.

💭 thought

Typical. Mechanical failure on the boat, structural failure on the dock, and I'm starving. I can't even stand straight.

🔧 Kevin11:26

Teredo. Creosote's failed at the waterline. How far up?

Drop to one knee on the dock, reach over the gunwale, and run my fingers up the piling from the waterline — probing for soft spots, measuring the rot depth with my knife blade.

💭 thought

She's right. Greenheart doesn't fray like that unless the teredo got past the creosote. Tide's high — can't see the full extent. If the main piling goes, the dock goes. Supply boat's due in nine days. No dock, no supplies. Engine vibration can wait. Pilings can't.

🌿 Jenny11:26

At least three feet. It's soft as cake.

Shift weight off the bad ankle and watch him probe the wood, face tight with hunger.

💭 thought

He's finally seeing it. If those go, the whole jetty slides into the surf. God, I need a piece of toast or something.

the garden · midday

Midday Heat

The punishing sun beats down on the island as the tide begins its slow turn.

The midday sun beats down on the garden as Kevin struggles to maintain the seedlings in the oppressive heat. Jenny works at the dock, checking the mooring lines and preparing for the receding tide.

🔧 Kevin11:28

Kevin — pull the loose tarp corner tight, drive the stake deeper with the mallet, wipe sweat from eyes

💭 thought

Should've done this at dawn. Ground's too hot to kneel on now.

🌿 Jenny11:30

Jenny — make sketch: Dock Piling Rot Diagram

💭 thought

Three feet of rot. It's not just a few soft planks; the foundation is giving way. Kevin is so focused on the engine's heartbeat that he can't feel the ground dissolving under his feet.

🔧 Kevin11:32

Kevin — walk the perimeter of the garden wall, test each tarp stake, kick dirt over the one lifting on the west side

💭 thought

Tarp's holding. Should check the other three corners while I'm down here.

🌿 Jenny11:34

Jenny — limp slowly back toward the cottage

💭 thought

My ankle is pulsing. I need to get off these planks and back to the cottage before I lose my balance.

🔧 Kevin11:36

Kevin — walk back to the cottage, grab the prop puller and socket set from the workshop, head down to the dock

💭 thought

West corner's solid now. Knees are complaining. Time to get the prop off the Yanmar before the tide turns.

the dock · afternoon

Afternoon Heat

Kevin and Jenny meet at the dock as the sun begins to dip. The tide is at its lowest point.

Kevin worked on the Yanmar prop shaft at his bench and secured the garden tarp. Jenny attempted to plant from grandmother's tin but struggled with her ankle and the delicate seedlings.

🔧 Kevin11:38

You're a long way from the porch.

Wipe hands on a rag, set it on the dinghy gunwale, and wait for her to reach the end of the jetty.

💭 thought

The light's changing. Tide's dead low — good time to check the prop shaft runout while the boat's sitting on the keel. Jenny's walking the planks I haven't replaced yet. She shouldn't be on that ankle.

🌿 Jenny11:38

I needed to see the waterline. And the pilings.

Walk slowly to the end of the jetty, favoring the bad ankle, and point a finger at the water-stained rot on the main support beam.

💭 thought

He's still thinking about the engine. He doesn't even see the wood turning to mush under his boots.

🔧 Kevin11:40

Rot's up to the cross-brace. Past it, likely.

Step off the dinghy onto the jetty, walk the length to the main pile, press the spike of the nail puller into the darkened timber at the cross-brace level, then a foot higher. The wood yields like cork.

💭 thought

Three feet above the waterline she said. At low tide that's the splash zone — worst place for rot. The greenheart sister held the ring but the beam itself is spongy. Supply boat in nine days. If a pile gives under her weight...

🌿 Jenny11:40

It's structural, Kevin. Not just surface rot. If we don't sister those beams before the next storm, the supply boat is going to have nowhere to tie up.

Lean back against a sounder piling and cross arms, watching him face the reality of the wood.

💭 thought

Finally. He doesn't need me to translate the decay when he can feel it collapsing under his own tool.

🔧 Kevin11:42

I'll start tonight. First low tide after dark.

Turn to the shed, haul out two of the sound cores and the crowbar, set them on the jetty beside the rotting pile, then pull the tarp from the generator and spread it over the tools to keep them dry as the tide comes in.

💭 thought

She's right. Three sound cores from the old planks are still in the shed, but sistering means lifting the load, cutting scarfs, epoxying under tension — and she can't bear weight on that ankle. Storm season's still weeks off, but the tide's coming in now. Every hour the water rises, the rotten piling takes more load.

🌿 Jenny11:42

Don't kill yourself doing it all in one go. You're exhausted.

Reach out and touch his shoulder briefly, then shift weight to the good leg.

💭 thought

He's moving so fast. It's his way of dealing with it—immediate action to drown out the anxiety.

🔧 Kevin11:44

I won't. Just get the scarfs cut before dark. Then I'll check the prop runout on the bench while the tide's high enough to float the dinghy off the keel.

Shoulder the crowbar and one sound core, walk back to the shed, set them down, then pull the prop shaft sleeve from the oarlock bracket and carry it to the workbench under the porch.

💭 thought

Her hand on my shoulder — warm, dry, the first real contact in days that wasn't about the ankle or the radio. She's watching me, not the wood. Tide's turning. Salt's in the air.

🌿 Jenny11:44

Fine. I'm going to check the seedlings.

Turn away from the porch and limp slowly back toward the garden, rubbing the side of the swollen ankle.

💭 thought

Back to the engine. The dock is a crisis for ten minutes, then he's back to the vibration. It's like he can't stand the silence of things just breaking.

the keeper's cottage · evening

Evening Medical Check

Kevin and Jenny are in the kitchen. Kevin is preparing a simple meal while Jenny sits with her ankle propped up on a chair.

Kevin and Jenny ate a meal of eggs and corned beef in the cottage while the heat pressed down. Kevin obsessed over the engine's vibration issues while Jenny focused on the swelling in her ankle. The dock rot remains untreated as the tide continues to rise.

🌿 Jenny11:47

The dock pilings are rotting, Kevin. Three feet up from the waterline. It's not just surface wear; it's structural.

Gently shift the ankle on the chair, wincing as the skin pulls.

💭 thought

He's humming. How can he hum when the dock is practically a sponge and my leg feels like it's being tightened by a vice? I can't even stand up without seeing stars.

🔧 Kevin11:47

Landward side holding?

Set the skillet on the stove, drop in a knob of corned beef fat, and let it melt while I wait for her answer.

💭 thought

Three feet up means the rot's eaten past the tidal zone. That's not splash — that's wicking. The sister knees I put in last month won't hold if the cores are gone. Need to check the landward pilings too, see if it's tracking inland.

🌿 Jenny11:48

Barely. The landward side is better, but the seaward ones are spongy. If we get a real surge before the supply boat, the whole thing could shift.

Reach for the antibiotic blister pack on the windowsill and slide one pill out.

💭 thought

"Holding" is a generous word for it. He always wants a binary answer—yes or no—instead of actually looking at the decay.

🔧 Kevin11:48

Swallow it.

Crack two eggs into the hot fat, whites spreading thin. Slide a plate toward her end of the table.

💭 thought

She's taking the antibiotic without water. Ankle's hot enough to feel from here. Red streaks didn't fade. She's not saying how bad it is.

🌿 Jenny11:50

I'll swallow it when I have water.

Take the pill and hold it in my palm, staring at the eggs.

💭 thought

He's not even looking at me, just the eggs. He knows the infection is climbing, but he can't bear to see the redness.

🔧 Kevin11:50

Kevin — pour water from the tank tap into a chipped enamel mug, set it down beside her hand.

💭 thought

Tank's at 363. Can spare a mug. She's counting.

🌿 Jenny11:52

Thanks.

way the pill and swallow it with a dry gulp, then rub the swollen ankle.

💭 thought

At least he brought the water. The heat in this kitchen is thick enough to breathe like wet wool.

🔧 Kevin11:52

Eat.

Slide the second plate over, fork on the side. Take my own seat opposite. Cut into the yolk, let it run.

💭 thought

Two doses left. If the streaks reach the knee by morning, we're past pills. Radio's working. Coastguard heard that Mayday last night — they're in range. But a medevac means leaving the island, the engine, the garden, the contract. She'd refuse. I'd have to make the call while she's unconscious.

🌿 Jenny11:54

I can't believe you're still obsessing over that vibration. The dock is the real problem.

Pick up the fork and push a small piece of egg around the plate.

💭 thought

I'm not even hungry, but if I don't eat, I'll just be tired and hungry and hurt. The yolk looks too rich for this heat.

🔧 Kevin11:54

Vibration's the shaft sleeve. Bench work's done. Need to pull the prop tomorrow, press it true. Dock needs greenheart sisters, epoxy, through-bolts. Don't have greenheart. Don't have epoxy. Have three sound cores from the last repair and oak wedges that split.

Eat a mouthful of egg white. Watch her push food around.

💭 thought

Vibration's the prop shaft. Dock's the pilings. Both can kill us — one slow, one fast. Supply boat in nine days. If the dock goes, no boat lands. If the engine fails, no dinghy to meet it. She thinks I'm choosing the engine. I'm choosing the thing I can fix with my hands right now.

the keeper's cottage · night

Night of the Heat

The heat finally breaks slightly, but the air remains heavy and humid. The sound of the tide lapping against the pilings fills the silence.

Kevin checks Jenny's swollen ankle as the dry season breeze settles through the cottage. The air is warm, and the high tide laps against the dock pilings, keeping them for now.

🌿 Jenny11:56

( way said)

Reaches for the cold compress and wraps it around her swollen ankle, wincing at the pressure.

💭 thought

My ankle is throbbing in time with the tide, and I can't even look at the dock without feeling the weight of that rot.

🔧 Kevin11:57

Let me look at it.

walk over to where she's sitting on the porch, crouch down beside her ankle, reach out to gently unwrap the compress

💭 thought

She's trying to hide how bad it is. That wince wasn't from the cold — it was from the weight of the wrap on skin stretched too tight. The red streaks I saw this morning haven't faded. They've probably spread.

🌿 Jenny11:58

It's fine, Kevin. Just swollen.

Pulls her leg away slightly, looking out at the half-weeded garden.

💭 thought

He's always trying to help, but I'm too tired to explain how much the dock scares me today.

🔧 Kevin11:58

It's not fine. Let me see.

stay crouched, wait with my hand outstretched, not reaching for her again but not pulling back either

💭 thought

She pulls away like I'm the one who'll break something. The ankle's hot through the bandage — I felt it yesterday. Antibiotics are down to two doses. If the streaks hit the femoral vein, we're not waiting for a supply boat.
