For 10 to 20 guests, the best value in Labuan Bajo is usually one right-sized open-deck boat or slow boat rather than a speedboat squeeze or two split hulls. On 2026 whole-boat rates, a single mid-size charter split across 14-18 people can land near USD 60-110 per person for the day, undercutting most shared per-person tours while keeping the whole vessel private.

Which boat classes actually hold 10 to 20 guests?
Capacity is the first filter. A group of 10-20 sits at the awkward hinge where small speedboats stop working and the open-deck, slow-boat and phinisi classes start earning their rate. Nera Wela Tour and Travel, in its 2026 whole-boat one-day pricing, tops its “medium speedboat” tier at 5-10 persons for Rp 10,000,000-13,000,000 (about USD 640-830) – which means a party of 16 has already outgrown that class and needs a deck-boat or larger.
Here is how the classes map to a 10-20 headcount, using 2026 signals:
| Class | Typical comfortable capacity | Fit for 10-20? | 2026 whole-boat signal |
|---|---|---|---|
| Small speedboat | 1-4 | No | Nera Wela: Rp 7-9M (USD 450-580) |
| Medium speedboat | 5-10 | Lower half only | Nera Wela: Rp 10-13M (USD 640-830) |
| Open-deck day boat | 10-20 | Yes – core fit | Best Komodo Tour: USD 800-2,500/boat by capacity |
| Slow boat / wooden day boat | 12-25 | Yes | Marketplace day spread (Click&Boat, Sailo) |
| Boutique phinisi | 10-20+ (overnight) | Yes – premium | Labuan Bajo Luxury: from USD 2,200/day |
Best Komodo Tour, writing in 2026, puts a private Komodo charter at USD 800-2,500 per boat depending on capacity and facilities – the open-deck and slow-boat sweet spot for exactly this group size. If your 10-20 want overnight cabins rather than a day deck, you cross into phinisi territory, where Labuan Bajo Luxury quotes boutique phinisi from USD 2,200/day. For the money-page view of groups this size, see our small-group boat charters overview, which frames the same classes around booking mechanics rather than the cost curve below.
How does per-person cost fall as the group grows?
The whole point of chartering at 10-20 is that the boat rate is fixed while the divisor rises. The marketplace averages back this up. Click&Boat’s 2026 data pegs a typical Labuan Bajo rental at USD 950-1,700 per day (average USD 1,992, full spread USD 1,025-3,068), while Sailo’s 2026 figures show day charters averaging about USD 1,100 with a minimum of USD 500. Take a representative mid-size day boat and watch the per-head number drop:
| Whole-boat day rate (2026) | 10 guests | 14 guests | 18 guests | 20 guests |
|---|---|---|---|---|
| USD 1,100 (Sailo avg day) | USD 110 | USD 79 | USD 61 | USD 55 |
| USD 1,500 (mid open-deck) | USD 150 | USD 107 | USD 83 | USD 75 |
| USD 2,200 (boutique phinisi) | USD 220 | USD 157 | USD 122 | USD 110 |
The curve is steep early and flattens late: moving from 10 to 14 guests cuts the per-head cost far more than moving 18 to 20 does. In practice the value plateau for a single mid-size boat arrives around 14-18 aboard – past that you are usually trading comfort and deck space for a few more dollars saved.
One large boat or two smaller boats?
At 16-20 guests the honest question is whether to book one bigger hull or split into two mediums. The math from 2026 rates leans toward the single boat, but not blindly.
- Two medium speedboats: On Nera Wela’s 2026 tier, two boats at roughly USD 830 each is about USD 1,660 for the pair – close to a single mid open-deck rate but with your group divided across two decks, two crews to coordinate, and two anchoring points at each stop.
- One open-deck or slow boat: A single USD 1,500 day boat keeps 16-20 guests together, splits cleaner (USD 75-94 per head), and simplifies logistics at Komodo landings.
- When splitting wins: If speed matters (spread-out itinerary, tight day) or your group genuinely wants two social pods, two faster hulls can be worth the coordination cost.
Base case for 10-20: one right-sized boat almost always beats two smaller ones on both price-per-head and hassle – unless raw speed is the priority.
Where is the charter-vs-tour break-even at this scale?
This site’s core thesis is that a full private boat beats per-person tours once the group is large enough, and 10-20 sits comfortably past that line. Best Komodo Tour’s 2026 shared pricing runs USD 60-150 per person for a one-day Komodo trip. Set that against the per-head charter numbers above:
| Option (2026 figures) | Per person, 16 guests | Privacy |
|---|---|---|
| Shared one-day tour (Best Komodo Tour) | USD 60-150 | Shared with strangers |
| USD 1,100 whole boat (Sailo avg) | ~USD 69 | Entire boat private |
| USD 1,500 whole boat (mid open-deck) | ~USD 94 | Entire boat private |
At 16 aboard, a whole boat frequently lands inside – or below – the shared-tour band while giving you the entire vessel. That mirrors the worked example this brand reuses: a medium speedboat at USD 830 whole-boat splits to about USD 104 per person with 8 aboard, already inside the shared band. Add eight more heads and the advantage widens. The general break-even against per-person tours lands at 6+ passengers; by 10-20 the case is decisive.
What could shift for 2027 – outlook, not prediction
Reading the 2026 signals forward: marketplace opacity is the standout pattern. Booking.com’s Labuan Bajo charter listing shows no price until you select dates, and AYANA Komodo Waecicu Beach offers charter only on a contact-the-team basis with no published day rate. That opacity rewards transparent per-boat rate cards, and the direction for 2027 is likely more groups pricing whole-boat hire directly rather than accepting undated averages. This is an outlook drawn from dated 2026 behavior, not a guarantee – rates move with fuel, season and demand.
Two more 2026 realities to carry into any 2027 budget. First, season swings are large: Click&Boat reports roughly USD 2,885/day in high season versus USD 1,154/day in low season, so the same boat can double. Second, park fees sit on top of the boat rate. Best Komodo Tour lists Komodo National Park entrance at about IDR 150,000-250,000 per person, a ranger at IDR 80,000-100,000 per group, and snorkeling or diving at IDR 50,000-100,000 per person – additional unless a written package states otherwise, and worth budgeting per head across your 10-20.

Frequently Asked Questions
What size boat should 15 guests book in Labuan Bajo?
For 15 guests, an open-deck day boat or slow boat in the 12-25 capacity range is the natural fit – a medium speedboat tops out around 10 on Nera Wela’s 2026 tiers. Using 2026 whole-boat rates near USD 1,100-1,500, fifteen guests split to roughly USD 73-100 each for the day, before park fees.
Is one boat cheaper than two for 18 people?
Usually yes. Two medium speedboats at about USD 830 each (Nera Wela, 2026) total near USD 1,660, versus a single open-deck day boat around USD 1,500 that keeps everyone together. The single boat typically wins on both per-head cost (about USD 83) and logistics, unless your itinerary genuinely needs the extra speed of two hulls.
How many guests make a private charter beat a shared tour?
The break-even generally lands at 6 or more passengers, and by 10-20 it is decisive. Against Best Komodo Tour’s 2026 shared one-day price of USD 60-150 per person, a USD 1,100 whole boat split across 16 guests is about USD 69 each – inside or below the shared band, with the entire boat private rather than shared.
