The cost of a cocktail dinner on a boat in Paris: per person and as a sample budget

We have already devoted an article to how a cocktail dinner unfolds on board. This one takes a complementary angle, purely financial: how much to allow per person, depending on the number of pieces served and on whether drinks are included, and then what overall budget that means for a group of 20, 50 or 100 guests.

The figures below are rough orders of magnitude observed in the Parisian events market, not contractual prices. The actual price depends on the caterer, the season, the boat and the level of service. They are meant to help you set a budget before requesting a detailed quote.

What the price of a cocktail dinner includes

When people talk about a "price per person", several cost items often get blurred together. To compare offers, they need to be separated:

• Boat hire: it depends on the duration, the time slot and the capacity, not on the number of pieces. It is priced separately.
• Savoury and sweet pieces: the catering element, charged per piece or as a flat rate per person.
• Drinks: soft drinks, wine, champagne, cocktails, with or without a barman.
• Service: maître d', waiting staff, barman, depending on the number of guests.
• Logistics: crockery, glassware, table linen, ice, and any quayside delivery charges.

A clear quote should show these lines separately. If an offer gives a single "all-inclusive" price, ask exactly what it covers, particularly as regards drinks and staff.

How many pieces per person?

The number of pieces determines both guest satisfaction and the bill. Three benchmarks come up regularly:

• 6 to 8 pieces: an enhanced aperitif, suited to an early-evening cocktail, an after-work gathering or a reception lasting an hour to an hour and a half, after which guests dine elsewhere.
• 10 to 12 pieces: the most common format for a cocktail reception that replaces a light meal, with a mix of cold pieces, hot pieces and one or two desserts.
• 14 to 18 pieces: a proper cocktail dinner, for an evening of two to three hours, sometimes with a workshop or live station (carving, wok, oysters depending on the season).

These benchmarks vary according to the audience. A group coming straight from a day's work will eat more than a gathering that is there mainly to chat. The longer the evening, the more you should plan for successive waves of service rather than a single round.

Price ranges per person

For the catering alone, excluding drinks, you can reason as follows, as a guide:

• 6 to 8 pieces: around €20 to €35 per person.
• 10 to 12 pieces: around €35 to €55 per person.
• 14 to 18 pieces: around €55 to €85 per person, more if stations or premium ingredients are planned.

For drinks, two approaches coexist. With a package of soft drinks, water, wine and a glass of champagne on arrival, expect a per-person budget well below that of an open bar with cocktails and a barman, which can easily be double. These amounts vary with the brands chosen and the length of service. Drinks charged by the bottle, billed according to what is actually opened, can suit a well-behaved group, whereas a flat-rate package limits unpleasant surprises.

Service is generally added on top: a larger team is needed on a boat, where movement is restricted, than in a room.

Sample budgets by group size

Here are three scenarios covering food and drink only. Boat hire, which depends on the package chosen, comes on top.

• 20 guests, yacht, 8 pieces, moderate drinks: roughly €20 to €35 for the pieces and a reasonable drinks budget per person. At this scale, the cost of service weighs proportionally more; some caterers impose a minimum order.
• 50 guests, barge or moored boat, 12 pieces, wine and champagne: the heart of demand. The catering budget falls within the middle range of €35 to €55 per person, to which you need to add drinks and two to three members of service staff.
• 100 guests, barge, 14 pieces, cocktail bar: the per-person price tends to fall on the food side thanks to volumes, but staffing and the bar costs rise. Plan for a full team and a second service point to avoid queues.

To go from the price per person to the total, multiply by the number of guests actually attending, then add a margin of 5 to 10% for no-shows and last-minute additions. This is more reliable than asking for a bare-minimum estimate.

How to keep the bill under control without making the reception feel stingy

A few practical levers help you stay in control:

• Shorten the bar's opening time rather than the number of pieces: drinks are the most flexible cost item.
• Choose an early-evening slot with 8 to 10 pieces rather than a full cocktail dinner, if the aim is networking more than a meal.
• Concentrate the budget on a few signature pieces rather than a long, uniform list.
• Check the caterer's terms: some boats have an approved caterer, others accept an outside supplier, which changes the pricing logic.
• Look at the quote as a whole: a cheaper boat with a mandatory caterer can end up costing more than a slightly pricier hire with a caterer of your choice.

Finally, state the number of guests, the desired duration and the level of drinks from the outset: a quote built on these three parameters can be compared from one offer to the next, and spares you successive revisions.
