Open Trip or Private Charter? The Break-Even Maths With Real Catnazse Numbers

Most articles answer this question with adjectives. This one answers it with the operator’s own published numbers, shown openly so you can check the arithmetic yourself.

The two price structures, side by side

Open trip is priced per person, by cabin. Private charter is priced per boat, by duration and guest tier. They are not the same unit, which is why comparing headline figures is meaningless until you normalise them.

The break-even maths

Take the 3D2N. Whole boat: USD 7,100 for up to twelve guests. Open trip at a representative mid-range cabin rate of USD 530 per person: twelve people would pay USD 6,360, and fourteen would pay USD 7,420. So the crossover lands between thirteen and fourteen — except that at thirteen guests the charter tier steps to USD 7,700, which at USD 530 each is matched at about fifteen people.

Illustrative arithmetic using the operator’s published 2026 rates and a representative USD 530 open-trip cabin price. Your actual figure depends on which cabins your group takes.

Two honest caveats. If your group takes the balcony suites at USD 650–680, the crossover arrives earlier. If it takes family cabins at USD 430–470, it arrives later. Run it with the cabins you would actually book — the open-trip rates used here and the charter rates used here have the full sets.

What money does not capture

Charter buys three things the arithmetic misses. Your own date — any day you like, not one of four or five published departures a month. Your own pace — a longer stop at Pink Beach, a later start, a swim where the schedule said sail. And no strangers, which for a family with small children or a company offsite is not a luxury but a precondition.

Open trip buys different things: a lower absolute cost, a fixed and well-drilled schedule, and other people on the sun deck — which a substantial number of solo travellers and couples actively want. Neither is the premium product; they are different products.

What 2027 rates do to the calculation

If your dates fall in 2027, run the numbers again — the charter ladder steps up, and it steps up unevenly. The short durations move a little; the long ones move a lot.

The practical reading: for two and three-day charters the two years are close enough that timing is not the deciding factor. From four days upward the gap widens sharply, and a longer 2026 charter is materially cheaper than the same trip a year later. The 2027 ladder also extends further, running out to 12D11N at USD 30,200 for one to twelve guests — the longer expedition routing that does not appear in the 2026 sheet at all.

A decision flow

• Two people: open trip, unless privacy is the entire point of the trip.
• A family of four to six: open trip with family cabins, or charter if the dates matter more than the money.
• Eight to twelve friends: genuinely close. Charter for the freedom, open trip for the budget.
• Thirteen or more: charter, on both money and practicality.
• A company group: charter. Fixed cost, whole boat, a karaoke room and a schedule you control.

The full price list carries both structures including 2027 rates, and if you are still deciding whether to be on a boat at all, the hotel-versus-liveaboard comparison is the prior question. The operator’s own charter overview shows how the same maths plays out across other vessels.
