Season decides what kind of work is sensible; tide decides which day it starts. On the Bira foreshore the drier months suit anything that opens a hull — planking, fastenings, seams, coatings — because timber has to be dry to work and finishes need settled weather. Wet-season slots remain useful for short cycles that do not expose structure.
Two clocks, not one
Every programme here runs against two independent constraints, and confusing them causes most scheduling disappointment. The tide governs the two irreversible events: the haul and the relaunch. The season governs everything in between — how fast timber dries, whether coatings will cure, how many working days are lost to rain, and how much competition there is for skilled hands on the beach.
A programme that fixes only the tide is a programme that will run into weather. One that considers only the season will find itself waiting a fortnight for water. The scheduling method used by the yard project management desk fixes the tide events first, then tests whether the work between them is realistic for the season it falls in.
What the drier months buy you
Workable timber
Replacement planking and frames can be fitted at a stable moisture content, and seams prepared without fighting damp. Work done wet moves when it dries.
Coatings that cure
Primers, stopping, paints and antifouling all have humidity and temperature ranges. Applied outside them, they look right and fail early.
Fewer lost days
An open hull under a rain squall stops work entirely. Across a ten-week programme, the accumulated stoppages are measured in weeks, not hours.
Predictable drying
Hulls needing to dry out before sheathing or coating do so on a schedule rather than whenever the weather permits.
The trap at the end of the dry window
The most expensive scheduling mistake made on this coast is starting a structural job late in the dry season on the assumption that it will be finished before the weather turns. Timber lead times, a survey that finds more than expected, and a single delayed material delivery are enough to push a nine-week programme into the wet months — at which point the hull is open, the work slows, and the boat sits on the beach through a season nobody planned for.
The desk’s rule is straightforward: if the scope plus a realistic contingency does not fit inside the remaining dry window, the honest options are to reduce the scope, split it across two haul-outs, or wait. Starting anyway and hoping is not a plan.
Splitting a scope across two haul-outs
Structure and everything that must be dry goes in the first window. Systems, joinery and finish — work that can proceed under cover — goes in the second. It costs one extra haul cycle and routinely saves more than that in weather losses and rushed decisions.
Labour competition is seasonal too
The skilled shipwright, caulking and joinery gangs on this foreshore are a finite resource, and they are busiest when the weather is best. A slot booked into a peak period without labour committed against it is only half a booking. Scope, slot and gang are confirmed together, which is one reason the desk asks for a written scope before holding a window rather than after.
Wet-season work that makes sense
Not everything needs to wait for the dry months. Short haul cycles — wash, inspect, anode renewal, antifoul in a settled spell — are entirely reasonable. So is anything conducted under permanent cover, and so are inspection-only hauls, where the point is to gather information for a scope that will be executed later. In fact hauling for a condition survey in the off months is good practice: it means the main programme starts with facts already in hand and materials already ordered.
How to choose your own window
- Define the scope honestlyIncluding the work you suspect will be found, not just the work you have decided to do.
- Add lead time for materialsLong planks, grown frames and specific timber species are not always in stock.
- Count working days, not calendar daysThen add a weather allowance appropriate to the season you are proposing.
- Fix the relaunch tide backwardsWork back from when the vessel needs to be afloat, not forward from when you want to start.
- Test the fitIf the result runs into the wet months with structure still open, revise the plan rather than the optimism.
