Who goes in first: sequencing spring installs

Which docks go in first? Most shops answer with some version of “whoever signed up first” or “whoever calls the most,” and both answers cost real money. Sign-up order sends the boat zig-zagging across the lake. Squeaky-wheel order teaches your customers to squeak.

The sequence that actually works is decided by three things, in this order: the water, the access, and the gear. Customer deadlines bend the sequence; they don’t set it. Here’s how each one works, and why the right unit of sequencing is the bay, not the customer.

First, the water decides

Ice doesn’t leave a lake evenly. Shallow, dark-bottomed bays open a week or more before the deep main basin; sheltered water is workable on days the exposed shore is whitecaps. Early in the season, part of your lake is available and part of it simply isn’t — so the first cut of the sequence is made for you. Work what’s open.

Water level is the other spring fact. High water can put a low fixed dock’s brackets underwater and make some shorelines easier to float sections into; low water grounds the barge short of shorelines you could reach all summer. Either way, the level you have in April is not the level you’ll have in June, and a stop that’s marginal now may be easy in three weeks. Let it wait.

Second, batch by bay

The most expensive minutes of an install day are the ones spent motoring between stops. Six properties in one bay is a day’s work; six properties scattered across a lake is a day’s driving with some work in it. So the sequence isn’t a list of customers at all — it’s a list of bays, and the boat clears each one before moving on.

This is the argument against sign-up order in one sentence: the March sign-up and the January sign-up live next door to each other, and any sequence that visits them on different days paid for the same boat ride twice.

Third, the gear sorts what’s left

Within a bay, gear does the sorting. If four stops need the crane barge and two need only the fork barge, that’s two different boat-days, not one mixed one — a crew that arrives at a lift it can’t set has wasted the trip, and a crane sent to do fork work wasted the crane. Batching by what the work needs is worth more than any per-customer priority, because it’s the difference between finishing a bay and visiting it.

Deadlines bend the sequence — they don’t set it

Real deadlines exist: fishing opener, the customer flying in Memorial Day weekend, the graduation party on the dock June 5th. Handle them as exceptions pulled forward inside the bay logic, not as the organizing principle. A season sequenced entirely by promises turns into a season of boat rides; a season sequenced by water and bays, with a handful of dated exceptions, keeps both the customers and the arithmetic happy.

And be honest about which deadlines are real. “Before the weekend we arrive” is real. “As early as possible” is a preference wearing a deadline’s clothes, and it goes in the bay order like everyone else.

Why “when the boat’s in your bay” beats a promised date

A promised date is a debt. Wind, a late spring, one slow stop — and now you’re not behind on work, you’re breaking promises, one phone call at a time. “We work your bay the week of” keeps the same information and none of the debt, and it’s the honest version: you genuinely don’t know which Tuesday, and pretending otherwise is how schedules die. Customers take the window better than most operators expect, because what they actually want is the dock in before their date — not a Tuesday for its own sake.

The sequence is a starting point, not a contract

However well you sequence, the wind gets a vote every single morning, and the right response to a west wind is to work the east shore — today, without ceremony, without re-planning anything. That’s the real reason to sequence by bay in the first place: bays are interchangeable in a way a dated customer list never is. Swap Tuesday’s bay for Thursday’s and nothing else moves.

This is also how dispatch works in LakeOps — you point a boat at a stretch of water and it takes what’s waiting there, so the sequence lives where it belongs: in the morning decision about where the boat goes, not written on five hundred jobs that would all need editing when it rains.

Water first, then bays, then gear, then the handful of real deadlines. It fits on a whiteboard — and unlike the whiteboard, it survives the weather.
