The economics of a Gili tourist boat business hinge on how many paying seats you move per day at a sustainable fuel, crew and maintenance cost per crossing. A sensible operator models capacity, seat load factor, daily crossings and a maintenance reserve, then tests how many monthly passengers at what average ticket price are needed to cover fixed and variable outgoings.
Route profile and operating pattern for Gili boats
Most Gili tourist boat operations are short shuttle routes between Bali or Lombok and Gili Trawangan, Gili Meno or Gili Air. Distances are modest, but sea state, monsoon season and harbour procedures affect trip time, fuel burn and mechanical wear.
A typical pattern on the Lombok–Gili axis might include:
- Base at Teluk Nara, Bangsal, Senggigi or Sekotong.
- One to three round trips per day in high season; one to two in low season.
- Turnaround time shaped by passenger handling and Syahbandar clearance.
- Weather-related cancellations factored into annual planning, not ignored.
Before running numbers, you need a realistic timetable and seasonal operating window, not a perfect-calendar assumption.
Capacity, seating layout and realistic load factor
Regulated passenger capacity is set by Kemenhub approval and the issued Surat Ukur and Gross Akte. Revenue capacity is what you can sell consistently at a given comfort level and ticket price.
Rated capacity vs economic capacity
- Rated capacity: Maximum passengers authorised on certificates.
- Economic capacity: Seats you can sell routinely without overloading baggage areas or compromising turnaround times.
- Seasonal reality: High-season sailings may approach rated capacity; low season often runs far lower.
Many operators use a planning seat load factor, the average percentage of seats filled over time, to smooth this variability.
Illustrative capacity planning
The table below shows indicative planning bands for a fast Gili passenger boat. These are not survey figures or a quote; they are planning assumptions to stress-test a business case.
| Parameter | Unit | Illustrative band |
|---|---|---|
| Rated passenger capacity | persons | 40–70 |
| Economic capacity per trip | persons | 35–60 |
| Average seat load factor (annual) | % of seats sold | 55–75% |
| High-season seat load factor | % of seats sold | 75–95% |
| Low-season seat load factor | % of seats sold | 35–55% |
Fuel consumption and cost per crossing
Fuel is usually the dominant variable cost for a Gili tourist boat business. Consumption depends on hull form, displacement, engine setup, cruising speed and sea state. A more detailed comparison of propulsion choices is covered in the article on outboard vs inboard Gili passenger boats.
Key fuel-planning drivers
- Route distance: For example, Teluk Nara to Gili Trawangan is short; Padangbai to Gili Trawangan is longer and more exposed.
- Service speed: Higher speed shortens travel time but raises fuel burn significantly.
- Propulsion configuration: Multiple high-horsepower outboards or inboard diesels.
- Sea condition: Head seas and wind increase resistance and burn.
For planning, many operators work with an indicative fuel burn per hour and a fixed cruise time per leg, then add a safety margin for rough days and harbour manoeuvring.
Crew cost, harbour fees and daily operating overhead
Crew cost sits beside fuel as a major daily expense. On a regulated passenger boat you must budget not only for helmsman and deckhands, but also for those handling ticketing, luggage and guest communication on shore.
Crew and shore team structure
- Skipper with the correct licence for the route and vessel size.
- Deck crew for lines, boarding, safety briefing and emergency response.
- Shore staff for check-in, baggage control and coordination with vehicles and agents.
- Occasional extra crew during peak luggage-heavy sailings.
Beyond wages, factor BPJS, uniforms, recurrent training and relief crew for leave. Harbour dues, Syahbandar charges and local retribution are usually modest per passenger but noticeable when combined with taxes and accounting costs.
Maintenance reserve and lifecycle planning
Gili fast boats see hard use: multiple cycles per day, hot sun, salt water and frequent berthing. Repairs will not be smooth or evenly spread; they will cluster around unplanned events and scheduled yard periods.
Practical maintenance cost categories
- Engines and driveline: Oils, filters, impellers, injectors, gearboxes, propeller work.
- Hull and structure: Antifouling, topside repairs, occasional structural reinforcement.
- Regulatory surveys: Work required to satisfy BKI or Kemenhub findings.
- Hotel systems: Seating, canopy, toilet, electrical and safety gear.
Many owners place a maintenance reserve aside per operating hour or per trip. This is not a warranty or guarantee; it is an internal allocation to avoid running short when a major service or unplanned grounding occurs.
Illustrative break-even calculation (example only)
The following worked example is an illustration, not a forecast, offer, or promise of performance. It shows one way to structure a break-even view for a single Gili route fast boat.
Assumptions for the illustration
- Certified passenger capacity: 60 persons; economic capacity 55.
- Two round trips per day on average; 26 operating days per month (allowing for weather and maintenance).
- Indicative average seat load factor over the year: 65%.
- Illustrative average ticket yield: USD 22 per passenger one-way.
Step 1: monthly passenger and revenue estimate
- Seats offered per day (one-way): 55 seats × 4 legs = 220 seats.
- Seats sold per day at 65% load factor: 220 × 0.65 ≈ 143 seats.
- Monthly seats sold: 143 × 26 ≈ 3,718 one-way passengers.
- Indicative monthly revenue: 3,718 × USD 22 ≈ USD 81,800.
Step 2: simplified cost structure illustration
This banded view is for planning only. Actual numbers depend on specification, staffing and finance structure.
- Variable costs (fuel, oil, harbour dues, per-trip cleaning, basic consumables): assume USD 5,500–8,000 per month.
- Crew and shore wages (including relief crew and basic benefits): assume USD 7,000–10,000 per month.
- Maintenance reserve (engines, hull, safety gear, yards): assume USD 4,000–7,000 per month.
- Insurance, permits, accounting, marketing and office overhead: assume USD 6,000–9,000 per month.
- Financing or depreciation allocation for the vessel: assume USD 10,000–18,000 per month.
That set of planning bands might put total monthly cost in a range of roughly USD 32,500–52,000.
Step 3: indicative break-even range
Using the revenue illustration (around USD 81,800/month), the boat might cover these hypothetical costs and leave a margin for owners, reserves and growth. If any of the key assumptions deteriorate—fewer operating days, lower seat load factor, weaker ticket yield or higher fuel cost—the break-even point slides upwards in passengers per month or in ticket price.
The value of this exercise is not in the specific figures, but in stress-testing different scenarios: low season vs high season, one engine out-of-service, or fewer daily crossings due to weather or port congestion.
Aligning build specification with operating economics
Hull choice, engine package and passenger layout all have direct cash-flow consequence. Some owners prioritise maximum speed to fit more crossings into a day; others prefer moderate speed, lower fuel burn and a longer engine life between overhauls.
When designing a new vessel, build decisions should be based on a route model and a financial model, not on aesthetics alone.
- Clarify target capacity and route set before fixing hull length and beam.
- Model fuel usage and service intervals for shortlisted engine options.
- Consider boarding arrangements at Bangsal, Teluk Nara and the Gili beaches.
- Align structural scantlings and laminate schedule with surveyor expectations for your intended service.
A tailored new build allows you to design towards a specific operating profile and cost structure. A starting point for hull and machinery options is the overview on our fast boat build page.
From planning bands to a formal quotation
When you are ready to move from high-level economics to a concrete project, the next stage is a technical and commercial proposal. That will normally include a concept general arrangement, outline specification, indicative build cost bands, and an estimated build schedule tied to contract milestones.
Each owner has different preferences: outboard or inboard, enclosed or open saloon, luggage handling concept, and intended flag and survey regime. This means there is no single standard “Gili boat price”.

Frequently asked questions
How many crossings per day make sense for a Gili tourist boat?
The practical number of crossings per day depends on route distance, port congestion and sea state. Many operators plan for one to three round trips, then trim schedules for low season. The key is protecting turnaround time for safe boarding and baggage handling while leaving margin for unexpected delays and routine engine checks between sailings.
What seat load factor should I use in my Gili boat business plan?
A planning load factor for Gili routes is often lower than peak-season expectations. Some owners work with an annual average in the 55–75% range, depending on marketing reach and competition. Using a conservative assumption for the first years helps ensure the business can handle weaker months without straining cash flow.
How do I estimate fuel cost for a new Gili fast boat?
Start from the intended cruising speed, route distance and engine package, then apply an estimated burn per hour and multiply by trip time. Add allowance for harbour manoeuvres and rough-weather penalties. For a new build, combine engine manufacturer data with local experience on similar routes, then stress-test the business model against higher fuel price scenarios.
What is a sensible maintenance reserve for a Gili passenger boat?
Many owners set aside a maintenance reserve per operating hour or per month, often framed as a planning band rather than a fixed rule. The reserve should be large enough to cover routine servicing plus occasional heavier work such as gearbox repairs, hull coatings and safety-equipment renewal, without forcing emergency cash injections when an unplanned yard visit is required.
Do I need a shore office to run a Gili tourist boat business?
A shore presence is highly desirable, even if small. You need space for passenger check-in, baggage control, accounting, crew coordination and liaison with travel agents or vehicle providers. Some operators share or outsource these functions, but someone must control manifests, ticket reconciliation, safety briefings and real-time communication with the vessel for schedule changes.
