Small group or large boat to Benagil: what the passenger numbers mean

Twelve passengers and forty-two passengers are not just different amounts of company. They change how a private booking is paid for, how your group sits together and what questions you need to ask about the boat. From Vilamoura, there is a concrete comparison: a private Benagil boat for up to 12 guests from €585, activity 1313981, and the private Lince catamaran for up to 42 from €890, activity 1376554.

Both start in Vilamoura, but their catalogue durations differ: two hours for the smaller private trip and three hours for Lince. The figures were recorded on 11 September 2026. Both products have zero reviews in that snapshot, so this is a comparison of published terms, not a claim based on previous passengers’ reports.

Private and small describe different things

A private boat for up to 12 is reserved for your party under the selected booking. It does not require you to bring twelve people. A small shared group, by contrast, can include strangers even if its maximum is lower. Decide first whether the important part is the number of passengers or keeping the booking within your own group.

Lince demonstrates the reverse: a private catamaran for up to 42 remains private despite its larger capacity. The word says who shares your booking, not how small the vessel is. Do not search only for private and assume all the results will have a quiet, intimate layout.

The price per person depends on who actually comes

For the €585 boat, a party of twelve would divide the starting price into €48.75 each. Six people would pay €97.50 each; two would pay €292.50 each. The boat has not become more luxurious as the group shrinks. Fewer people are sharing the same quoted total.

For the €890 Lince charter, ten people would pay €89 each, twenty would pay €44.50 each, and forty would pay €22.25 each. These examples deliberately use actual party sizes below the stated maximum. Do not divide by forty-two if you only have ten confirmed guests. The unused places do not pay the bill.

These calculations use the catalogue starting prices, without assuming extras or a child discount. Ask for the total for your date, party and planned programme. If one family drops out, recalculate before everybody agrees to a contribution. A group organiser should also establish who holds the booking and receives any refund.

A passenger capacity is not a comfort rating

There is no universal size hidden behind the word catamaran. As an illustration of the range in this marina, Ocean Quest publishes a capacity of 110 passengers for its named boat. That is a different vessel from Lince. Neither number tells you how many tickets will be sold on a particular shared departure.

Ask for the expected maximum booked on your sailing, not only the vessel’s technical capacity. Then ask whether your party can sit together and whether everybody has the kind of seat you need. A low passenger number does not identify shade, backrests or a toilet. A larger boat does not tell you how crowded the best viewing position becomes.

This is also why the €45 shared Benagil catamaran and the €585 private boat cannot be ranked just by dividing prices. They sell different arrangements, with different durations. The local catamaran list and private charters are useful together, provided you compare the actual passenger terms.

Fewer guests do not reserve the cave

Your charter may be private, but Benagil is not reserved for your group. Ask whether the chosen boat normally enters and how the skipper handles a route change. Do not infer access from the word small, and do not infer exclusion from the word catamaran. The relevant answer concerns that boat, that programme and the conditions on the day.

The same applies to photography. A small party may find it easier to take turns, but the charter does not guarantee an empty backdrop or extra time at a viewpoint. If you want family photographs together, explain that before booking and ask where on the vessel it is practical. This is more useful than buying unused seats in the hope that the cave itself will be less busy.

When the larger private boat fits better

For a celebration involving several households, Lince’s capacity may let everyone travel on one booking. For six friends, the smaller private boat has a lower total in this comparison, though its published trip is an hour shorter. For a couple, neither total is close to two ordinary shared tickets; privacy needs to be something you actively want.

Do not turn a group excursion into a compulsory outing for the least enthusiastic relative. Ask whether non-swimmers can stay aboard during any offered swim stop, whether food may be brought, and how the return time is handled. If individual needs cannot be confirmed, use separate cave-trip bookings that each household can choose independently. The passenger number should solve a real problem for the group before it becomes the reason to charter.
