Stag or Hen Party on a Boat: Ideas, Games and Activities on Board

A stag or hen party on a boat has everything it takes to be epic: the whole group together, the Tejo river all around, music, sun (or stars) and no neighbours telling you to turn it down. But what do you actually do during those hours on board? Here are the fun ideas, games and activities that make the day unforgettable — and how it all works, from boarding to the final toast.

How a party on a boat works

It’s simpler than it sounds. You charter a private catamaran (just for your group, up to 37 people), board at Doca de Alcântara, and the boat is yours for the whole trip. The crew handles the sailing and the logistics; you handle having fun. You can pick a daytime programme (sun, swimming and water sports) or a night-time one (DJ, lights and party) — or both.

For the practical side — prices, capacity, what’s included — see the guide on how to plan a stag or hen party on a boat. This article is about the good part: what to do on board.

Fun ideas for the party on board

Little touches that make all the difference:

• Theme or dress code — matching t-shirts with the guest of honour’s name, a single colour, tropical, 80s… it helps with the photos and the group spirit.
• “On-board kit” — squad sunglasses, sashes, balloons and a welcome poster with a funny photo.
• Coordinated surprise — plan a moment (a video from family and friends, a message from someone who couldn’t make it) to reveal halfway through the trip.
• Cocktail contest — with open bar, each “team” invents a cocktail and the guest of honour crowns the winner.
• Deck photobooth — props, a giant frame and the 25 de Abril Bridge as the backdrop.
• Mid-trip swim — a stop for a dip (Sail & Swim) breaks the programme in half and cools everyone down.

Games and activities to play on board

Easy to prepare, guaranteed to lift the mood (and bring on the laughs):

1. “Who knows them best” quiz — questions about the bride or groom; whoever gets it wrong pays a forfeit (a shot, a dance, a dip).
2. Challenge list — each guest draws a card with a fun mission to complete during the trip (e.g. “make a toast in rhyme”, “teach a dance routine”).
3. Truth or dare, group edition — the classic that never fails with everyone sat on the deck.
4. Party bingo — cards with likely “events” of the day; first to complete wins.
5. Karaoke / playlist battle — everyone adds their song to the boat’s sound system and the group votes for the “king/queen of the party”.
6. Secret gift — small surprise presents for the guest of honour, handed out throughout the trip.

Tip: prepare 2–3 games, not 10. On board, the scenery, the music and the water do half the work.

Day or night? Choose the vibe

• Daytime programme — sun, a swim stop, water sports (jet-ski, wakeboard, towable tube) and lunch on board. Ideal for groups who want energy and sea.
• Night-time programme — a boat party with a DJ, lights and the sunset kicking off the celebration. Ideal for those who want to dance with Lisbon lit up all around.

Can’t decide? Combine the two: a sunny afternoon and a swim that slides into a party at nightfall.

Music: a DJ or your own playlist

The sound makes the party. You can bring a DJ on board or connect your playlist to the boat’s sound system via Bluetooth. Pair it with an open bar and cocktails and the scene is set. For groups who want a proper party, check out the boat party in Lisbon.

Tips for a party that goes off without a hitch

1. Book early — summer weekends sell out.
2. Match the programme to the group — not everyone wants the same thing; balance party, swimming and downtime.
3. Flag any dietary restrictions for the catering.
4. Appoint a discreet “ringleader” for the surprises and the games.
5. Respect for the boat and the crew is the only rule. 😉

Frequently asked questions

What can you do at a stag or hen party on a boat? Plenty: group games (the bride/groom quiz, challenges, bingo), a cocktail contest, a deck photobooth, karaoke, a swim stop and water sports, and a party with a DJ at sunset. The boat is private, so the programme is tailored to your group.

Is it just for men, or for hen parties too? Both. We organise stag and hen parties in the same way — the games, the music and the extras adapt to whatever the group wants.

Can we bring decorations, games and gifts? Yes. You can bring sashes, balloons, props and your own games. We can also sort out the DJ, catering and themed decoration if you prefer.

How many people can come? Up to 37 guests, on a private catamaran, just for your group.

Is it better by day or by night? It depends on the group: by day for sun and swimming; by night for a party with a DJ. Many combine the two — an afternoon at sea that turns into a party at nightfall.
