A micro wedding at sea is a small celebration, usually with fewer than 30 guests, held aboard a private yacht instead of in a venue. In Barcelona it works best with a tight guest list, a legal ceremony handled on land and a boat that has one job for the day: you. On our yacht the practical limit is 11 guests, which suits couples who want the sea, the skyline and the people who matter, without a crowd.
This guide covers what counts as a micro wedding, what Spanish law means for a ceremony on a boat, how to choose a vessel, ideas that make the day feel personal, the budget logic and a weather plan.
TL;DR
- A micro wedding is generally a celebration of around 10 to 30 guests, and a yacht in Barcelona suits the smaller end of that range. Our private charter takes up to 11 guests.
- A legally valid marriage in Spain needs a marriage file and an authorised official. Plan the legal step with the Civil Registry, then celebrate at sea.
- Choose the boat on stability, space, catering and access for every guest, not only on looks.
- Our private yacht charter is published at €350–€2,400 per group, and multi-day charters start from €1,200 per day. Food, flowers and music are planned around that.
- Keep a flexible date and a plan B for wind and swell. We design our booking terms to be refund-friendly.

What counts as a micro wedding at sea
There is no legal category called a micro wedding. It is a planning term for a celebration far smaller than the traditional guest list. Spanish wedding planners describe it as a smaller-scale celebration with 10 to 40 guests, with 15 to 30 the most balanced format. A Mallorca wedding magazine puts it nearer up to around 20 guests, and separates it from an elopement, which is usually just the couple and perhaps a tiny handful of people.
A yacht changes the arithmetic. A boat has a fixed number of seats, a fixed deck plan and a captain who answers for everyone on board. That is why a micro wedding yacht celebration in Barcelona usually sits below the 20-guest mark. With us, the number is 11 guests on a single private boat, so the question is rarely “who can we squeeze in” and almost always “who do we truly want next to us when the sun goes down”.
If you are torn between a full micro wedding and something even smaller, it helps to look at how elopement planning and coordination services frame a custom ceremony: a handful of chosen people, a setting that means something, and every detail designed rather than inherited. Aboard a yacht in Barcelona the same logic applies, with the Mediterranean as the venue.
Micro wedding, elopement or vow renewal
- Elopement: the couple and a very small circle. Often a surprise proposal or a private ceremony with no guests at all.
- Micro wedding: a short guest list, a proper meal, music, photographs and a sense of occasion.
- Vow renewal: for couples already married who want to mark an anniversary. We have a page on planning a yacht vow renewal in Barcelona.
The legal side: what Spanish law asks of a wedding on a boat
This is the part couples most often get wrong, so it comes before the decoration.
The Spanish Civil Code says a marriage requires prior proof of capacity through a marriage file, and normally takes place before the competent judge, mayor or authorised official, with two adult witnesses. For civil effects, the marriage must be registered in the Civil Registry. The same text contains a narrow exception for a marriage aboard a ship or aircraft, but it applies only when one of the parties is in mortal danger. It is not a route for planned weddings.
What that means in practice:
- Do the legal marriage through the official channel. Ask the Civil Registry or the town hall where you intend to marry what the file requires.
- Foreign couples start earlier. If you live outside Spain, contact the relevant Spanish Civil Registry or your consulate about which documents are needed, such as passports, birth certificates, proof of marital status and official translations. Requirements and timings differ by case.
- Treat the yacht as the celebration. Many couples complete the legal step on land, then hold the vows, the toast and the dinner at sea with their closest people. Confirm with the authority handling your file what can and cannot be done on board.
We do not replace that legal process, and we would not want you to rely on a boat ceremony until you have confirmed it with the authorities. What we do is make the celebration itself calm, private and well run. For a deeper look at the guest limit that applies on the water, read our guide on Spanish law and guest caps for a wedding at sea.
Choosing the right boat for a small wedding
For a wedding party of up to a dozen people, comfort and stability matter more than size. When you look at vessels, compare them on these points.
Capacity and layout
Count everyone: couple, guests, photographer and any musician or chef. Then ask how many people the boat is licensed to carry at sea, and how many can sit for dinner at once. A boat that carries a crowd standing may still be a poor place for a seated meal.
Our private charter is built around up to 11 guests. That figure is deliberate: it keeps the group small, the service personal and the dinner table intact. Our small yacht wedding ideas for 11 guests page shows how couples shape a day within that number.
Stability and comfort
If you or your guests are prone to seasickness, ask about the boat’s behaviour in swell and about a plan for calm, short routes close to the coast. Choose a route that keeps the boat gentle during the vows and the meal, and save any sailing or swimming for later in the day.
Facilities on board
Check shade, seating, toilets, a place to change and somewhere to store a dress, jackets and shoes. Ask where food is prepared and served. Our private dining at sea experience includes an onboard chef, which keeps catering inside the same private space.
Access and safety
Boarding is the moment where a wedding outfit meets a gangway. Tell us in advance about anyone with limited mobility, young children or an elderly relative, so the crew can plan the boarding and the seating. Flat soft-soled shoes are far better than heels on a wet deck, and a pair of spares in a basket is a graceful solution.
The captain and the crew
A wedding is a day with a timetable, and a boat is the one venue that cannot overrun without consequences. A personally captained experience, with a crew whose only guests are yours, lets the pace follow the moment instead of the schedule. That is the core of how we work.
Boat wedding ideas that feel personal
A small wedding lets you spend on quality rather than quantity. Wedding planners in Spain note that with fewer guests, couples can invest more in gastronomy and personalised décor. On a yacht, that translates into a few good decisions.
Time the day around the light
Sunset is the obvious choice for a reason: warm light, calmer afternoon air and a skyline that does the decorating. A late afternoon departure gives you time for the vows in good light, then a toast as the sun drops. Our sunset cocktail on a private yacht is a natural format for the toast.
Make dinner the centre of the day
With 11 guests, one long table is possible. A chef cooking on board, wine chosen with the couple and a menu that reflects where you are from turns the meal into the memory. Our guide to culinary experiences on yachts goes through how to shape a menu at sea.
Keep the décor minimal
A yacht is already beautiful. Fresh flowers on the table, a simple arrangement at the bow for the vows and good linen are enough. Heavy arches and large installations compete with the sea and are hard to secure on a moving deck. Wind is the designer’s constant: anything that cannot survive a breeze should stay ashore.
Write the vows, skip the formalities
Vows read aloud at the bow, with the coast behind you, need no stage. Ask a friend or a sibling to lead the moment. Add a playlist, a short reading and perhaps a surprise from a guest. Keep the programme short enough that nobody is holding a glass for twenty minutes.
Add one active moment
Some couples like a swim stop with the group during the afternoon. Our water sports and swimming option can be added to a charter, which suits younger guests and gives the day a relaxed second half.
Plan the proposal or the surprise
If the day starts as a proposal and grows into a celebration, plan it with the crew. Our guide to creating a memorable yacht surprise explains how to coordinate flowers, music and photography without alerting the guest of honour.
What a micro wedding at sea costs in Barcelona
A yacht wedding is not priced like a venue hire with a per-head menu. The main cost is the boat and crew for the time you want it, with food, drink, flowers, photography and music added around it.
Here is what we publish:
| Item | Published price |
|---|---|
| Private yacht charter | €350–€2,400 per group, one-off |
| Multi-day charter | From €1,200 per day |
| Sphynx Gift Card | From €450, one-off |
The range for a private charter reflects the length and format of the trip, so the number you pay depends on how long you want the boat and what you add. Private dining, a sunset cocktail and other experiences are quoted together with the charter, and we do not publish a fixed price for them. Ask for a quote built around your date and your guest count.
How to build your budget
- Start with the boat and the time. Decide whether you want two hours for the vows and a toast, or a longer afternoon with dinner.
- Add food and drink. Choose between a cocktail, a seated chef-led dinner or a lighter menu.
- Add the people. Photographer, musician, florist and any officiant for a symbolic moment.
- Add the land side. Legal paperwork, transport for guests, hotel rooms and a welcome dinner the night before.
- Keep a margin. A weather change or a late request is easier to handle with some budget spare.
Weather, season and the backup plan
A wedding at sea depends on the sea. The skipper decides whether conditions are safe, and a sensible plan accepts that from the start.
- Pick a flexible date. If you can, choose a primary and a reserve date during your stay. Our booking terms are designed to be flexible and refund-friendly, so ask us how a change of date is handled for your booking.
- Plan the wind. Light dresses, hair that holds and secured décor all matter. A shawl or a jacket for each guest is useful after sunset, even on a warm day.
- Have a second venue. A restaurant table or a terrace on land is the usual plan B for a day when the boat cannot go out.
- Ask the captain. The skipper reads the forecast and the coast every day. Their advice on timing and route is worth more than any app.
- Think about sun and shade. Shade, water and sun protection are not optional for an afternoon on deck.

A timeline for a micro wedding on a yacht
A simple sequence keeps the day easy for everyone.
- Months ahead: start the legal file with the Civil Registry, fix the date and the guest list, and request a quote.
- Weeks ahead: confirm the menu, the music, the photographer and any dietary needs or access needs among the guests.
- The days before: check the forecast with the captain and confirm the reserve plan.
- Boarding: welcome drinks on arrival, with the crew handling luggage, gifts and flowers.
- At sea: vows and photographs first, while everyone is fresh, then the meal and the toast at sunset.
- Return: a calm final stretch into port, with time for a last round of photographs.
Our perspective
We think a small wedding at sea is the most honest kind of luxury: no queue of strangers, no schedule imposed by a venue, only the people you chose and a coastline that needs no decoration.
That is why we run one boat, with a personally captained, hospitality-first approach. A group of up to 11 guests means we know every name before you board, and we can slow the day down or move it forward as the light and the mood require. Custom itineraries are not an extra for us, they are how we plan.
Our advice to couples is to settle the legal side early, keep the guest list to the people who would sit beside you at a dinner table, and spend on the meal, the music and the hour of sunset. The rest is the sea.

FAQ
How many guests can a micro wedding at sea have?
Micro weddings are generally described as celebrations of around 10 to 30 guests. On a private yacht the number is set by the boat and the rules at sea. On our boat it is up to 11 guests, which keeps the day intimate and the dinner seated.
Is a wedding ceremony on a boat legally valid in Spain?
Spanish law requires a marriage file and a ceremony before an authorised official, then registration in the Civil Registry. The exception for ships applies only where one party is in mortal danger. Confirm with the Civil Registry or town hall what is possible for your case, and plan the yacht as the celebration around it.
What are good boat wedding ideas for a small group?
A sunset departure, one long seated dinner prepared by a chef, simple fresh flowers and vows read at the bow all work well. A swim stop or a surprise from a guest adds personality. Keep décor light, because wind and movement make large installations impractical.
What happens if the weather is bad on the day?
The captain decides whether it is safe to sail, so it helps to have a reserve date and a land-based plan B. Our booking terms are designed to be flexible and refund-friendly. Ask us how a date change would work for your booking.
