An oyster and seafood bar on a boat in Paris

None of our articles has yet looked at one of the formats most loved by food enthusiasts: the oyster bar. Here we approach it from a practical angle, that of the organiser: how to set up an oyster shucking station on board, what quantities to plan for, which wines to serve, at what time of year, and under which hygiene rules.

The principle is simple and elegant. On a privately hired boat, a seafood counter becomes both a tasting moment and a meeting point: guests move around, help themselves and chat while the Seine glides by. Here is how to get it right, whether you are planning a cocktail reception or a dinner.

Why an oyster bar suits a boat so well

Oysters are enjoyed standing up, with your fingers or a small fork, with no knife and no porcelain plate. They are a product perfectly suited to a reception where people move about, between the deck and the saloon. They also encourage conversation: guests choose their size, their lemon, their shallot vinegar, and compare notes.

The setting works in your favour. A white counter, crushed ice, a little seaweed and some citrus fruit blend naturally with the maritime atmosphere of a boat. The result is visually striking without any extra decoration. For a brand, a company or a family who wants an elegant moment without heavy protocol, it is an option that stands out.

The oyster shucker on board: who, where and how

Opening the oysters to order is what makes the difference. A professional shucker, often provided by your caterer or a partner fishmonger, opens them in front of the guests and keeps the supply flowing. Plan for one shucker per group of roughly forty to fifty guests to avoid queues; beyond that, a second station is essential.

Choosing the location is a real logistical question:

• a counter or high table, accessible from both sides, with a workspace for the shucker;
• a flat, easy-to-clean floor, away from the main walkways;
• a water point or tubs for the shells, which are cleared regularly;
• a sheltered area in case of rain or wind, as wind sends ice and napkins flying.

Constraints vary depending on the boat (barge, yacht, moored boat). We recommend checking the layout during a site visit and having the caterer's equipment approved beforehand: tubs, ice, worktop and any power supply needed.

What quantities to plan for, depending on your format

Quantities depend mainly on the place the bar takes in your menu. As a guide, and to be adjusted with your caterer:

• Cocktail reception or aperitif: three to four oysters per person, supplemented with a few prawns or whelks if other bites follow;
• Cocktail dinner (canapés and finger food): the bar is one station among others, with a slightly lighter portion to leave room for the rest;
• Dinner: as a starter, around six oysters per guest; as a main course, move to a fuller platter with crustaceans, shellfish and accompaniments.

Think about variety on the platter: rock oysters in several sizes, possibly some flat oysters, then prawns, winkles, whelks, langoustines and brown crab. Also provide alternatives for those who do not eat them: vegetable tartare, blinis, rillettes made with cooked fish, cheeses. An oyster bar is not for everyone; a few guests will not touch it, and that is perfectly normal.

White wine and drink pairings

Oysters call for freshness, minerality and clean acidity. A few safe choices:

• a Muscadet sur lie, classic and saline;
• a Chablis, more taut and mineral;
• a Picpoul de Pinet, lively and approachable;
• a Sancerre or an Entre-Deux-Mers, depending on taste;
• a blanc de blancs champagne, for a more festive version.

For a cocktail format, two white wines and a sparkling option are enough. Serve them well chilled, in ice buckets on deck or in coolers on the tables. Do not forget non-alcoholic options: sparkling water with lemon, apple juice, iced tea. If you would like to explore wine pairing further, our article on wine tasting on board will give you some pointers. For the rules on alcohol and the bar, please also refer to the terms of your boat.

Seasonality and choosing your produce

Tradition recommends the months with an "r", from September to April, when rock oysters are firm and flavourful. Autumn and winter are therefore the natural seasons for an oyster bar, which works well: an event on the Seine at the end of the year, with the city lights, is particularly fitting.

In summer, oysters are still available, but they are more often milky during the spawning period. A good fishmonger will know how to guide you; ask for seasonal oysters of traceable origin, and let the professional advise you on sizes. In summer, you can also showcase prawns, crab and cold dishes based on cooked fish.

Hygiene rules and precautions

Seafood requires a rigorous cold chain. Here are the points to confirm with your supplier:

• cold storage until the moment of opening, and presentation on ice throughout;
• fresh supplies, delivered the same day or the day before depending on the supplier's practices;
• shucking as you go, rather than a large quantity opened in advance;
• trained staff, with clean worktops and appropriate hygiene practices;
• removal of any products that have been left too long at room temperature, particularly in hot weather.

Warn your guests: crustaceans and molluscs are among the allergens that must be declared, and raw products are not recommended for pregnant women, young children or vulnerable people. Provide clear signage and an alternative on every table. Our article on dietary requirements and allergies on board covers this organisation in detail.

Cocktail or dinner: which format to choose

For a cocktail reception, set up a central counter or two stations at either end of the boat, with continuous service. Guests help themselves at their own pace, and the bar doubles as entertainment. It is the most flexible format for a large group or a corporate reception.

For a dinner, two approaches work well: a seafood platter served at the table for sharing, or an oyster bar early in the evening, before the starter and main course. The second lets you follow on with a more traditional menu, while the first makes seafood the heart of the meal.

In every case, tell the Sein'ario team about your plans when you request a quote: we can advise you on suitable boats, the conditions for having a caterer on board and the possible layouts. Your caterer, or the one we recommend, will do the rest.
