Private vs Shared Day Charter: When to Skip the Shared Boat

Q: Is a shared day charter cheaper than private?

Per person, yes. Per group above four people, often not. A 6-person Ibiza shared trip at $220 per person is $1,320. A 6-person private day on a 14m motor yacht is $2,200 to $2,800. The gap narrows fast as the group grows.

Q: How many people are on a shared day charter?

Typically 10 to 16 on a 14m to 18m catamaran. Some operators load up to 24 on a 20m boat. The headcount and the route are usually fixed.

A shared day charter in Ibiza in July 2026 runs $180 to $240 per person on a 16-passenger catamaran. A private day on a comparable 14m motor yacht is $2,400 to $3,200 for the yacht. The shared option looks like an obvious win until you put four people in the comparison and the math flips. By six people, the per-person delta is small. By eight people, private wins on cost as well as on every other axis. That is the calculation no shared operator wants you to do at the booking page, so we have done it here.

The standard shared-catamaran route is the same in every destination

Before we get to the math, the structural problem. A shared day charter is built around an operator-optimised loop: a stop for swimming, a stop for lunch on board, a stop for a beach club or a snorkel reef, a return to base. The loop is the same every day. In every major day-charter destination, the shared catamaran route is set:

Ibiza: marina to Es Vedrá to Cala Salada to Formentera (Illetes) and back. Departure 1000, return 1730
Mykonos: marina to Rhenia anchorage to Delos for swim to a south-coast beach and back. Departure 1000, return 1800
BVI day shared: Road Town to The Baths at Virgin Gorda to Cooper Island for lunch and back. Departure 0900, return 1630
Saint-Tropez shared: Sainte-Maxime to Pampelonne for the beach club run. Departure 1030, return 1700
Cabo San Lucas shared: marina to El Arco to Santa Maria Bay for snorkel and back. Departure 0930, return 1600

The route is fixed because the operator has negotiated marina slots and beach-club fees against a fixed schedule. The schedule is profitable at full occupancy. You will share the day with 10 to 16 strangers and you will not deviate. If you want to spend the morning at Es Vedrá and the afternoon at Cala Bassa, the shared catamaran is not the product.

The break-even math

Take Ibiza as the worked example. As of May 2026:

Shared catamaran day, all-in (including basic lunch, soft drinks, snorkel kit): $200 per person
Private 14m motor yacht with skipper and one hostess, 8-hour day, no fuel surcharge: $2,600
Private 18m motor yacht with skipper, mate, and one hostess: $4,200

Per-person calculation, ignoring tip and provisioning:

Group size	Shared cost	Private 14m	Private 18m
2	$400	$1,300 each	$2,100 each
4	$800	$650 each	$1,050 each
6	$1,200	$433 each	$700 each
8	$1,600	$325 each (max load 8)	$525 each
10	$2,000	n/a	$420 each
12	$2,400	n/a	$350 each

The 14m private equalises with the shared at roughly four people and becomes cheaper at five. The 18m private equalises at six and becomes cheaper at seven. Above eight people the private option is cheaper on a per-person basis and the experience is materially different (own route, own playlist, captain's discretion on stops, hostess service that knows your name).

Add a 10% tip, $40 to $80 per person of food and alcohol over the basic catering, and a $50 to $100 fuel surcharge during peak season and the private case strengthens further because most of those costs scale with the yacht, not the headcount.

The math runs similarly in Mykonos, Saint-Tropez, the BVI, and the Costa Smeralda. The break-even moves slightly with the local rate band. The shape is the same.

When shared still wins

For two reasons.

The group is two or three people and the destination is a high-rate market. A couple in Mykonos in August, where a 14m private is $5,500 and the shared catamaran is $250 per person. The math says shared, with a clear conscience. The compromise is the fixed route and the company. Most clients in this profile take the shared catamaran, have a good day, and would not have spent triple for the difference.

The destination is one of the four where shared is genuinely the better product. They are: the Phang Nga Bay long-tail and traditional boat operators (small craft, intimate, only a few people per boat, a private equivalent does not exist at the same quality); the Komodo island-hop where the operator-pooled boats have permits and individual charters do not; the Galápagos cruise circuit where everything is shared by regulation; and the Whitsundays "Camira" and similar sail-day boats where the yacht itself is the point and you go because of it, not despite the company.

Outside those, shared is a price decision, not a quality decision.

Where private always wins

Six clear cases.

A family with children under 12. The shared boat is not built for them. The loud music starts before lunch, the deck is full of strangers, the toilet queue is real, the food is geared to adults. A private with a hostess who can warm the bottle and play UNO with the eight-year-old at the back of the yacht is a different product.

Any group over six adults. The per-person math has flipped. Private is now cheaper on cost and better on every other axis.

A trip where dietary requirements matter. A vegan, gluten-free, observant, or allergen-restricted client on a shared catamaran will eat the bread and a side salad. The chef on a private has a brief and a budget.

A celebration: birthday, anniversary, engagement, bachelor or bachelorette party. A private boat is a venue. A shared catamaran is a Tuesday with strangers who are also celebrating. Pricing the venue against the moment makes the private case obvious. A Mykonos birthday on a 22m private for 14 guests at $9,500 is $680 per head and the yacht is yours. The shared catamaran at $250 per head is $3,500 for the group and you sing happy birthday next to a hen party from Manchester.

A corporate or client-entertainment day. The shared boat is not professional cover. If you are entertaining clients, partners, or recruits, the private boat is the only option that signals what you intend it to signal.

Any day where the photo or video matters. A wedding-pre-shoot, an Instagram-driven trip, a milestone family portrait. You cannot control the background or the deck or the lighting on a shared catamaran. You can on a private.

The hidden shared-charter costs

The $200 per-person price is rarely the only cost. The four extras that show up at the dock or on the platform's final-confirmation page:

Beach club entry fee. The shared catamaran "stops at Formentera" but the beach club entry at El Pirata or Beso Beach is $35 to $80 per person extra and the yacht does not wait long enough to skip it
Bar tab. The "all-inclusive" is usually water, soft drinks, and one beer per hour. A bottle of cava is $40 to $60. A bottle of Whispering Angel is $90 to $120
Tip. Standard 10% to 15%. Not waived because it is shared. Most operators add a 10% gratuity automatically and the crew sees most of it
Transport to and from the marina. The Ibiza shared catamaran usually leaves from Marina Botafoch, which is a $25 to $50 taxi from most southwest coast hotels

Realistic all-in for a couple on a $200 per-person shared day in Ibiza is $550 to $650, not $400. That further closes the gap to the private 14m.

What "shared" actually covers in 2026

Shared day charter is not one product. There are four distinct sub-types and the term covers all of them on the booking pages we audit.

Open-deck catamaran day, 12 to 16 pax. The standard. Bunk-row seating on the back deck, a netting trampoline at the bow, basic lunch served buffet-style on board, a loud sound system. $150 to $280 per person depending on destination.

Smaller-group sailing day, 6 to 10 pax. The premium version. A 12m to 14m sailing yacht, often a Sun Odyssey or a Bavaria, with a captain and one mate. The day is calmer, the route is the same, the lunch is better. $200 to $400 per person.

Party-boat day, 30 to 80 pax. Not the same product. Loud, often theme-branded, branded shots service, the yacht does not really anchor anywhere quiet. $40 to $120 per person and almost never the right choice unless that is the actual plan.

Cabin-charter cruise, multi-day. Two to seven nights, shared cabins on a 25m to 35m motor yacht or sailboat. Common in Greece, Croatia, and the Galápagos. Different product entirely and we cover it in our shared-cabin charter explainer.

When you read "shared catamaran" on a booking page in Ibiza or Mykonos, you are almost always reading about the first type. When you read it in Croatia or Greece, you are sometimes reading about the second or the fourth. Confirm before paying.

Passed on

The party-boat day in Ibiza, Mykonos, and Dubai. We do not link to the operators in this segment, even where the affiliate commissions are highest in the day-charter market. The product is structurally bad on three axes (overloaded, often non-compliant on the published passenger limit, weak crew-to-guest ratio) and the safety record is the worst in the day-charter category. A private day at the lower end of the rate band is a better choice in every case, and a shared catamaran from a vetted operator is a better choice when the budget is tight. If a party boat is genuinely the plan, our position is that the right product is a privately booked party boat with a known operator, not a public ticket.

How to decide in five seconds

If you remember nothing else from this post, run this test.

Two people, mid-range budget: shared catamaran from a reputable operator, with the expectation that the day is the route, not the yacht
Two people, no budget constraint, special occasion: private 14m, no question
Three to four people: private 14m breaks even and wins on quality
Five to eight people: private 14m to 18m is cheaper per head and structurally better
Nine or more people: private 18m to 22m is decisively the answer
Family with under-12 children at any group size: private
Celebration or corporate-entertainment day at any group size: private

The shared-charter market has a real role for the budget-constrained couple and for the four destinations where shared is the actual product. Outside those, the answer is private and the math supports it.

FAQ

Is a shared day charter cheaper than private? Per person, often yes for groups of two to four. Above five people, private is usually cheaper per head and is materially different in product.

How many people are on a shared day charter? 10 to 16 on the standard 14m to 18m catamaran. Up to 24 on a 20m party-boat configuration. The booked headcount is the maximum the operator will run.

Can I pick the route on a shared charter? No. The shared-charter route is fixed and runs the same stops at the same times every day. Route control is the main difference you are paying for when you go private.

Is the lunch included on a shared charter? A basic lunch, yes. Buffet-style, served on board, usually a pasta, a salad, fruit, water, and one drink. Anything more is extra at bar prices.

Are there shared sailing-yacht day charters? Yes, in Greece, Croatia, and the BVI. They are quieter than the catamaran-party format and run smaller groups (6 to 10) at slightly higher per-person rates.

Can I book a half-shared, half-private day? No. The operator either runs the day as private (you book all available cabins or seats) or as shared (a fraction of capacity). A few operators offer a small-group private (6 to 8) on a vessel that would otherwise carry 16 shared, but at the full-vessel rate.
