A full boat charter in Labuan Bajo usually beats per-cabin booking once your group fills about 70 percent of a vessel’s berths. Groups of 10 fit Silolona exactly, 14 fit LAMIMA, and 18 fit Prana, and chartering buys a private itinerary, one deposit, and one Siora permit manifest for Komodo National Park.
Every week our reservations desk fields the same question from group organizers: should we book cabins on an open trip, or take the whole boat? After a decade of sailing Komodo National Park — our team has operated here since 2015, and TripAdvisor named us Best Boat Agency in Labuan Bajo in 2024 before recognizing us again as a 2025 Travelers’ Choice winner — we can tell you the answer is almost always a math problem, not a taste problem. This guide walks through that math by group size, then covers the three group formats we plan most often (corporate retreats, weddings at sea, and family reunions), the deposit and planning timeline we recommend, and how group permits actually work under the Siora app rules in 2027. I’m Mira Mahendra, liveaboard specialist on the Labuan Bajo liveaboard team, and this is the exact framework we use internally when a group inquiry lands on my desk.
When a Full Boat Charter Beats Per-Cabin Booking
There are only two ways to sleep aboard a phinisi in Komodo. On an open trip, you buy cabins and share the boat, the schedule, and the dinner table with other travelers. On a full boat charter, you take every berth, and with it, control: departure date, route, pace, menu, music, and who is on board. Both are legitimate ways to experience a Labuan Bajo liveaboard — we run both across our fleet and partner vessels — but they suit different groups.
The financial tipping point is occupancy. Published liveaboard pricing in Labuan Bajo runs per person per night: roughly US$150–250 on budget boats, US$250–350 midrange, and US$800–1,500+ on luxury vessels. A charter, by contrast, is priced for the boat, and as operators we price full charters below the sum of every cabin sold individually — otherwise nobody would ever charter. Our rule of thumb after hundreds of group bookings: when your party fills about 70 percent or more of a vessel’s berths, the full boat charter is usually the cheaper option per person, not just the nicer one. Below 60 percent occupancy, per-cabin booking on an open trip almost always wins on price, and the charter becomes a privacy decision instead of a value decision.
A quick midrange example makes it concrete. Ten friends paying US$300 per person per night on an open trip spend US$3,000 per night as a group. If those same ten travelers charter a 10-guest boat, they are buying exactly the capacity they use — no empty berths subsidized, and the charter rate reflects that. The same ten people chartering an 18-guest boat, however, are paying for eight berths they will never sleep in. Match the hull to the headcount and the charter wins; mismatch it and the open trip wins.
Group Booking Math by Group Size: 6, 10, 14, and 18
Here is how the group booking decision plays out against our four flagship vessels. Capacities are fixed, so the occupancy percentages — and therefore the verdicts — are too.
| Group size | Best-fit flagship | Capacity | Cabins | Occupancy if chartered | Our verdict |
|---|---|---|---|---|---|
| 6 guests | Fenides | 11 guests | 5 cabins | 55% | Per-cabin booking usually costs less; charter only if total privacy outweighs price |
| 10 guests | Silolona | 10 guests | 5 heritage suites | 100% | Full charter wins outright — you fill the boat exactly |
| 14 guests | LAMIMA | 14 guests | 7 suites | 100% | Full charter wins — the grand sailing phinisi at perfect occupancy |
| 18 guests | Prana | 18 guests | 9 suites across four decks | 100% | Full charter wins — the largest single-boat group we can host in one hull |
Two notes on the edges. A group of six is our most common awkward size: too big for a double cabin arithmetic to feel simple, too small to fill a flagship. For six, we usually quote a smaller midrange partner vessel from our wider fleet for charter alongside per-cabin pricing on Fenides, and let the numbers decide. And a group of 11 is Fenides’ sweet spot — at 100 percent occupancy across her 5 cabins, she flips from “expensive privacy” to “obvious charter.” Groups larger than 18 split across two hulls sailing in convoy, which sounds like a compromise but in practice becomes its own kind of fun: two boats, one shared itinerary, and a friendly race into every anchorage.
Corporate Retreats, Weddings at Sea, and Family Reunions
Roughly a third of our full charters are events, not vacations. Each format changes how we plan the boat.
Corporate retreats
A phinisi is the most effective offsite venue we know, mostly because nobody can leave early. For leadership teams of 10–14, LAMIMA and Silolona work as floating boardrooms: mornings for structured sessions on the shaded deck, afternoons for Padar ridge hikes and reef time that do the team-building without a facilitator. We handle the logistics companies care about — invoicing in USD or IDR, itemized cost breakdowns for finance, and a single manifest so HR is not chasing eighteen individual bookings.
Weddings at sea
Sunset ceremonies at anchor, with Padar’s ridgeline behind the vows, are the most requested event we plan. Prana’s four decks give a wedding party of 18 genuine separation — ceremony deck, dinner deck, dance floor, and quiet corners — while smaller celebrations suit Silolona’s heritage intimacy. Be realistic about headcount: 18 guests aboard is a wedding; 40 guests means a day-boat flotilla joining the mother ship for the ceremony, which we can arrange, but it is a different budget conversation.
Family reunions
Multigenerational groups are where chartering earns its keep in ways no spreadsheet shows. Grandparents nap while teenagers snorkel; the galley cooks two menus without complaint; the crew adjusts the pace daily. For families of 12–14, LAMIMA’s seven suites solve the who-sleeps-where puzzle cleanly. The one thing we insist on for reunions is a single decision-maker on the group side — one aunt with authority beats twelve opinions on a WhatsApp thread every time.
Deposits and the Group Planning Timeline
Full charters are planned further ahead than cabin bookings because you are reserving an entire vessel’s calendar. This is the timeline we work to with group organizers.
| When | What happens |
|---|---|
| 9–12 months out | Reserve the vessel and dates — essential for July–August and the Christmas–New Year peak, when flagship charters sell out first |
| At reservation | 30% deposit holds the boat exclusively; we stop selling those dates the moment it lands |
| 6 months out | Route, event details, and dive plans confirmed; provisional guest list started |
| 60 days out | Balance due; final menu, celebration, and special-request planning locked |
| 30 days out | Final manifest with passport details for the Siora app permit entries |
| 14 days out | Park permits secured under the daily quota; flight and hotel alignment double-checked by our team |
Shoulder-season charters (May–June, September–November) can compress this timeline to 3–4 months, and last-minute gaps do appear — but a group of 14 wanting LAMIMA over New Year should treat 12 months as the real deadline, not a cautious one. Dry season runs April through November; manta season peaks December through March, which quietly makes a January family charter one of the best-value, best-wildlife weeks on the calendar.
Group Permits via the Siora App in 2027
Komodo National Park now operates under a daily visitor quota of roughly 1,000 people, piloted since April 2026, with all entries booked through the government’s Siora app in three timed sessions: 06:00–11:00, 11:00–15:00, and 15:00–18:00. For groups, this changes the booking logic in one important way — your whole party must hold permits in the same session window, or half your group watches the other half climb Padar. This is a genuine advantage of the full boat charter: one manifest, one session, one confirmation, handled by us. We walk through the mechanics in our Siora app booking guide, but on a charter you will never open the app yourself.
Budget the park fees per person per day: IDR 250,000 entry, IDR 75,000 guide, and IDR 25,000 conservation — IDR 350,000 (about US$21) per guest per park day. Ranger treks are charged per group of five or fewer: IDR 200,000 on Komodo or Rinca and IDR 150,000 on Padar. A group of 14 therefore needs three ranger groups — IDR 600,000 for a Komodo landing, IDR 450,000 for Padar — and a full four-day Labuan Bajo liveaboard charter for those 14 guests carries roughly IDR 19,600,000 (about US$1,190) in park fees alone. We itemize all of this in every charter quote, because a Labuan Bajo liveaboard proposal that hides the fees is not cheaper, just less honest.
FAQ
How far in advance should we book a full boat charter in Labuan Bajo?
For peak dates — July, August, and the Christmas–New Year window — reserve your vessel 9–12 months ahead with a 30 percent deposit. Shoulder-season charters in May–June or September–November can often be confirmed 3–4 months out, but flagship boats like LAMIMA and Prana still book earliest.
Is a full charter cheaper than booking cabins for a group of 10?
Usually, yes — if the hull matches your headcount. Ten guests fill Silolona at exactly 100 percent occupancy, and our charter rates are set below the sum of all cabins sold individually. The same ten people chartering an 18-guest vessel would pay for eight empty berths, so vessel fit decides the answer.
Can our whole group visit Komodo in the same time slot under the quota?
Yes, and a charter is the safest way to guarantee it. We submit your entire manifest through the Siora app under one timed session — 06:00–11:00, 11:00–15:00, or 15:00–18:00 — within the park’s ~1,000-visitor daily quota, and we arrange the ranger groups of five that every landing requires.
