Haul-Out Capacity Planner

Two constraints, and yards count the first one

Time. How many hulls fit through the machines in the hours you have left. A cycle-time question, and the one everybody works out.

Ground. Whether those hulls then fit in the yard. An area question, and the one that bites.

Plan on time alone and you run out of room before you run out of list — with boats out of the water, a lift still working, and nowhere to put the next one. That is the worst moment to discover a constraint.

Hull dimensions are not the number

A yard that plans on hull length times beam is planning on a number no boat occupies.

The real figure is the hull plus the blocking, plus the space a person needs to walk between them with a jack stand. Add that margin across forty boats and it is a substantial fraction of your yard — enough to be the difference between the last six coming out and staying where they are.

This counts the space you actually consume, in your own figures, because how tight you block is a decision your yard makes about your ground and your risk.

Every boat that stays in the water is named, with the reason

And the reason matters, because the two constraints have completely different answers.

Stopped by time means another machine, an earlier start, or a second crew. A staffing and scheduling problem.

Stopped by ground means somewhere else to put them — a field, a lot, an arrangement with the yard up the creek. A completely different phone call, made to a different person, needing a different lead time.

A list that just said “these forty-one come out and these nine do not” would leave you working out which problem you have while the clock runs.

It predicts nothing about the storm

The hours remaining is a figure you type in, from whatever you are watching — the forecast office, the marine channel, your own read on it.

This does not fetch a track, does not estimate an arrival, and does not have an opinion about the weather. It takes your number and every answer on the page moves with it. Change the hours and watch the list change, which is the useful thing to do with it at four in the afternoon when the timing shifts.

It counts, and the yard decides

Which boat comes out first is contracts, relationships, and knowing who has been at the dock eleven years and who arrived in June.

This does not rank customers, does not prioritize by value, and does not produce an order to work in. It tells you how many fit, in the time and the space you have, and which constraint stopped the rest. The list is yours to order, and the page says so in those words.

What it replaces

The plan made on a whiteboard with a marker while three people talk over each other, using a boat count and a rough sense of the yard. Which is often right, and which has no way of being checked before the thing it is planning for arrives.

You set your machines, your cycle times and your yard once. Each time is the hours and the list.

Who it is for

Boatyards, marinas and dry stacks — anywhere hulls have to come out against a deadline that is not negotiable, and the ground runs out before the list does.

What it will not do

It predicts nothing about the weather. Your hours figure is the input.

It ranks no customer. Not by value, not by tenure, not by anything.

It suggests no blocking margin and no cycle time. Those come from your machines, your crew and your ground.

Nothing you type is sent anywhere. The arithmetic runs in your browser — which also means it works when the power is unreliable and the internet is the first thing to go. Close the tab and it is gone.
