The Humid Afternoon

The tide remains high, lapping against the dock while the Yanmar engine sits silent in the dinghy, waiting for a test that the dock cannot yet support.

Kevin and Jenny went to the dock to assess the rot in the main piling. Jenny sketched the extent of the decay while Kevin used a crowbar to find the point where the wood was still solid.

🌿 Jenny06:57

The wood is too soft, Kevin. It won't hold.

Pick up the pencil and sketch the specific pattern of the rot on the main piling.

💭 peek at the thought

If that plate fails, the dinghy goes with the current and I'm stuck here with nothing but weeds.

🔧 Kevin06:58

Aye. It's gone too far for a patch. We'll need to cut out the rot and sister in a new section—use one of the salvaged planks from the old dock. It'll take most of the afternoon, but it'll hold.

walk to the garden shed, grab the crowbar and salvaged plank, then head to the dock to assess how much of the piling needs replacing.

💭 peek at the thought

The rot's worse than I thought—it's eaten back past where the doubler plate could bite. Jenny's sketch shows it's not just surface decay; the piling's honeycombed inside. No sleeve or plate will grip that. We need to sister in new timber or scrap the ring entirely. But the supply boat's due in five days—if we can't secure it, they can't tie off safely.

🌿 Jenny06:59

I'll get the measuring tape. We need to know exactly where the solid wood starts.

Stand at the edge of the porch and watch the waterline where the rot meets the clean timber.

💭 peek at the thought

If we don't cut it out now, the whole structure will shear when the next storm hits.

🔧 Kevin06:59

I'll probe from the dinghy while you measure from the dock. Find the top of the rot—mark it with chalk.

push off in the dinghy with the crowbar and a piece of chalk, row to the seaward side of the piling, and start probing the timber at and below the waterline to find where the wood hardens.

💭 peek at the thought

She's right—need to find the sound wood before we cut. The tide's high enough to hide the lower rot line, but we can probe from above and below the water mark. The salvaged planks are sound; three good cores from the last repair. One should span the bad section if we sister it proper with through-bolts and epoxy that'll actually cure this time. Might need to warm the resin tins in the sun first—humidity's been killing the bond.

🌿 Jenny07:01

Be careful with that waybar. If you split the remaining solid, the whole thing will crumble.

Kneel on the dock and measure the distance from the deck to the first sign of decay.

💭 peek at the thought

He's so optimistic about the wood, but the salt has already claimed the core.

google/diffusiongemma-26b-a4b-it

🔧 Kevin07:01

Got it—feeling the change about two fists below the waterline. I'll mark it there and work up from solid.

use the tip of the crowbar to gently tap and feel along the piling just below Jenny's mark, listening for the shift from hollow thud to firm knock, then lightly score the transition point with the chalk without prying or splitting the wood.

💭 peek at the thought

She's watching close—knows I get impatient with the bar. The wood's spongy near the tide line, but I can feel where it firms up just below. Need to mark that transition without driving the bar too deep. One solid plank, sistered with bolts through both old and new, should carry the load if we keep the rotten core out of compression. Epoxy's just to keep water out—not structural. The bolts are what count.

nvidia/nemotron-3-super-120b-a12b

🌿 Jenny07:03

Mark it another inch higher. We need to overlap the joint completely so the new wood actually has something to grip.

Trace the measurement in the notebook, noting the exact depth of the decay line.

💭 peek at the thought

Two fists? That's deeper than I feared. The structure is basically a sponge.

google/diffusiongemma-26b-a4b-it

🔧 Kevin07:03

Right. One inch higher—marked.

adjust the chalk line up one inch on the piling, then row back to the dock to fetch the drill, auger bits, and the longest salvaged plank from the shed.

💭 peek at the thought

She's thinking load path—smart. Overlap the sister so the bolts bite into solid wood above and below the rot, not just at the edges. That means a longer plank and more bolts, but it's the difference between a repair that lasts a season and one that lasts years. We've got the three salvaged cores; one's long enough if we stagger the bolts. Need to drill pilot holes so we don't split the new timber driving them home.

nvidia/nemotron-3-ultra-550b-a55b

🌿 Jenny07:05

I'll start the pilot holes now. I don't want the bolts splintering out the remaining good wood.

Lay the salvaged plank against the

💭 peek at the thought

If I don't get enough overlap, the whole thing will just pull out the first time the boat knocks against it.

google/diffusiongemma-26b-a4b-it

🔧 Kevin07:05

Cut the plank to match your holes. I'll be right there.

climb up onto the dock from the dinghy, tie off the painter, grab the handsaw and measuring tape from the tool roll, and measure the salvaged plank against Jenny's pilot hole pattern to mark the cut line.

💭 peek at the thought

She's already ahead of me—drilling from the dock side while I was on the water. Good. The auger's sharp, she's got a steady hand, and she knows to angle the holes slightly downward so water won't pool in them. I'll cut the plank to length once I see her hole pattern, then we'll bolt it up from both sides. Through-bolts with washers and nylocs—four top, four bottom, staggered. The epoxy tub's nearly empty but there's enough for a bead along the mating faces to seal out water.

nvidia/nemotron-3-ultra-550b-a55b

🌿 Jenny07:07

Take your time with it. We need a clean edge or the epoxy will just bead up and fail.

Watch the edge as he saws, checking the tension on the tide again.

💭 peek at the thought

If the cut is even a hair off, the plate won't sit flush against the rot-free wood.

google/diffusiongemma-26b-a4b-it

🔧 Kevin07:07

Got it—nice and square.

saw slowly and steadily along the marked line on the salvaged plank, keeping the blade vertical and letting the teeth bite without binding, until the plank separates cleanly.

💭 peek at the thought

She's right—ragged grain traps moisture and keeps the epoxy from wetting the wood. Slow strokes, let the saw do the work. The tide's still high, lapping just below the piling; if we rush and split the end, we'll have to start over. The plank's dense old-growth—saws clean if you don't force it. After this, we'll dry-fit, apply epoxy to both mating surfaces, drive the bolts, and let it sit. No rushing the cure.
