Yard time should fall where it costs the fewest operating days and where the weather suits the work. For vessels working eastern Indonesia those two considerations usually point at the same part of the year, which makes the planning question less about when and more about how much scope fits inside it.
The geography that shapes the calendar
Bira sits at the corner where the South Sulawesi peninsula meets the Flores Sea. Selayar lies to the south-west; the routes east lead towards the eastern Indonesian cruising grounds that drive most charter and expedition demand. That position is the practical reason the coast matters to working vessels: it is a place with real timber capability sitting close to the transit routes rather than far from them.
The consequence for scheduling is that a haul at Bira does not necessarily mean a long delivery passage away from the operating area — which changes the arithmetic compared with hauling somewhere convenient but less capable.
The three-part year for a working vessel
Operating season
The months the vessel is committed. Nothing structural belongs here, and even short maintenance is a disruption.
Yard window
Low demand plus workable weather. This is where structural scope goes, and it is finite.
Shoulder periods
Transit, short cycles, inspections and preparation for the next yard window.
Using the shoulder for inspection
The most useful scheduling habit a working owner can adopt is to haul for inspection in a shoulder period, well before the main yard window. The vessel comes up, is opened in agreed areas, sounded and sampled, and goes back in. Nothing is repaired. What is produced is a scope built on facts, with materials identified and ordered, so that when the yard window opens the programme starts at full speed instead of spending its first fortnight discovering what it is.
This single change removes the most common cause of overrun on seasonal refits — the discovery phase eating the working window — and it is why the desk prices inspection as a distinct stage, as described under survey and condition reports.
Do not let a season decide the scope
If the honest scope will not fit the window, the answer is to split it across two years, not to compress it. Compressed structural work is how good yards produce disappointing outcomes.
A workable annual pattern
| Stage | Activity | Purpose |
|---|---|---|
| Late operating season | Defect log maintained by crew | Real evidence rather than end-of-season recollection |
| Shoulder | Inspection haul, scope written, materials ordered | Removes discovery from the critical path |
| Yard window | Structural work first, then systems | Weather-dependent work in the right weather |
| Late yard window | Joinery, finish, coatings, commissioning | Work that can proceed under cover |
| Pre-season | Relaunch, take-up monitoring, alignment afloat, sea trials | Faults found alongside, not on charter |
The defect log nobody keeps
Crews notice things all season and remember a fraction of them by the time the vessel reaches the yard. A simple running log — what, where, when, with a photograph — turns a season of observation into a scope document. It costs nothing, it makes quotations more accurate, and it consistently reveals patterns that a single inspection misses, particularly slow leaks and intermittent system faults.
Balancing convenience against capability
There is a real trade-off between hauling close to where the vessel works and hauling where the right skills and materials are. For a wash and antifoul, convenience wins comfortably. For planking, fastenings, seams or structural repair, capability wins, because the cost of having that work done poorly is paid over the following decade. The rule of thumb this desk applies is simple: if the work will still be visible in the hull in twenty years, choose capability. That reasoning is developed further in budgeting a timber hull refit.
Planning horizon
A full season ahead for structural work. Slipway windows, labour commitment and long-lead materials all need fixing before the window arrives, and the good windows are taken first. Owners who begin the conversation a month before they want to haul are usually negotiating for what is left rather than choosing what is right — the practical consequences of which are set out in planning a haul-out window at Bira.
Multi-year planning
Vessels last decades and budgets do not arrive in one lump, so the most useful planning horizon for a working boat is three to five years rather than one. A simple rolling plan — what must be done this yard window, what is scheduled for the next, and what is being monitored beyond that — turns a series of reactive haul-outs into a maintenance strategy.
It also changes how findings are handled. A defect discovered mid-season is no longer a crisis requiring an immediate decision; it is an item to be logged, assessed at the next inspection haul, and placed in the appropriate window. That framing removes most of the pressure that causes owners to approve rushed work, and it is the single habit that most reliably separates vessels that age well from vessels that are perpetually being repaired.
