The master of the vessel decides whether a charter sails. That authority is not negotiable and sits above the operator’s sales desk and the guest’s preference. A fair Indonesian weather policy offers a reschedule within the season, a shortened or sheltered route at the same rate, or a partial refund where neither is possible — and it states the decision time, usually the evening before or 06:00 on the morning of departure.
Who actually makes the call
Under maritime practice everywhere, and Indonesian practice specifically, the master of the vessel has final authority over whether and where the boat sails. The charter desk cannot overrule it, the owner cannot, and neither can a guest who has flown a long way for this one day. If a policy document suggests otherwise, that is a warning sign rather than customer service.
What guests can reasonably expect is that the call is made early, explained in plain terms, and accompanied by an option rather than a shrug.
What the skipper is looking at
- Wind strength and direction — and crucially whether wind is against tide, which builds a short steep sea in the straits around Bali far faster than wind alone.
- Swell period. A two-metre swell at fourteen seconds is comfortable; one metre at five seconds is unpleasant.
- Tidal streams. The Badung and Lombok straits run hard, and the timing of slack water often decides departure time.
- Squall risk. In the wet season, convective squalls build and pass quickly, which sometimes means delaying two hours rather than cancelling.
- Visibility, for a route with reef passages or an early start.
- The guest list. A crossing that is fine for six adults is a different decision with a toddler, a pregnancy or an elderly guest aboard.
The seasonal pattern behind all of it is set out in our month-by-month sea conditions guide.
Three outcomes, not two
Guests expect a binary — sail or cancel. In practice the most common outcome is the third one.
| Outcome | When it happens | Usual commercial treatment |
|---|---|---|
| Sail as planned | Conditions within limits | Nothing changes |
| Sail a modified route | Crossing is rough, sheltered water is fine | Same rate, different anchorage |
| Delay departure | Squalls passing, tide against wind early | Same rate, shorter day or later finish |
| Cancel | Conditions outside limits all day | Reschedule, or refund per the policy |
The modified route is worth understanding because it is where most disagreements arise. A group that booked to see Nusa Penida and is offered a day inside Benoa bay may feel short-changed even though the operator has behaved correctly. Agreeing the fallback route at booking removes that argument entirely.
What a fair policy says
- Who decides — the master, named as such.
- When — typically the evening before for a full-day charter, or by 06:00 on the day.
- What is offered on cancellation — reschedule within the season, credit, or refund, and in what proportion.
- What happens on a shortened day — pro-rata credit, or nothing, stated plainly.
- What happens if you cancel for weather but the boat would have sailed — normally treated as a guest cancellation under the standard ladder.
That last point catches people. If the skipper is willing to sail and you decide the forecast looks unpleasant, that is your cancellation, not a weather cancellation, and the deposit terms in our deposits and damage guide apply.
Insurance is not a substitute
Some travel policies cover trip disruption where a supplier cancels; many exclude weather cancellation of an excursion entirely. Check your wording rather than assuming, and read it alongside the operator’s policy so you know which one is meant to respond. The distinction between operator cover and your own is set out in our day guest insurance guide.
How to reduce the risk before you book
- Book early in your stay. A charter on day two of a ten-day trip can be moved; one on the last day cannot.
- Ask for the fallback route in writing at booking, so a modified day is a plan rather than a disappointment.
- Prefer a sheltered itinerary in the wet season if your group includes anyone prone to seasickness.
- Depart early. Mornings are calmer almost year-round, and an early start leaves room to delay rather than cancel.
- Choose the right hull. A catamaran in short chop is far more comfortable than a monohull of the same length.
When the call goes against you
The reasonable response is to take the reschedule if you can, or the modified route if it is offered. Skippers who cancel are giving up their own day’s earnings; nobody in the chain benefits from a cancelled charter. Pressing a crew to sail against their judgement is the one request a professional operation will always refuse, and correctly so.
If you want the weather policy in writing before you commit, ask for it with the quote. Send your dates and group to our team on WhatsApp at +62 811-3941-4563 or email [email protected], and ask for both the standard route and the sheltered alternative for your date.
Frequently Asked Questions
Who decides if a charter sails in bad weather?
The master of the vessel, and that authority sits above the charter desk, the owner and the guest. A fair policy states this plainly and gives a decision time, usually the evening before or by 06:00 on the day.
Do I get a refund if weather cancels my charter?
It depends on the policy. Common fair outcomes are a reschedule within the season, a credit, or a partial refund. A shortened or sheltered route at the same rate is the most frequent outcome in practice.
What if I cancel because the forecast looks bad but the boat would have sailed?
That is treated as a guest cancellation under the standard ladder, not a weather cancellation, so the normal deposit terms apply. Ask the skipper for their assessment before deciding.
How can I reduce the risk of a weather cancellation?
Book early in your stay so the day can be moved, depart early when conditions are calmest, agree a sheltered fallback route in writing at booking, and choose a catamaran if anyone in the group is prone to seasickness.
