The brokerage fleet assembled at the Cannes Yachting Festival this week is worth about half a billion dollars. According to BOAT International, more than 45 of the boats for sale measure over 25 metres, which makes the opening event of the autumn season unusually heavy on large tonnage rather than on the small and mid-size stock that normally fills a September show.
That matters because the next two weeks are when most of the year's big brokerage deals are shown, negotiated and set up. Cannes runs from 8 to 13 September and the Monaco Yacht Show follows from 23 to 26 September. What sits on the docks across those two weeks is the clearest read available on what owners are trying to sell, and at what size.
The largest in-water show, under a new director
The 49th Cannes Yachting Festival is the world's largest in-water boat show. Yachting News reports more than 680 exhibitors and a fleet of around 700 boats from 5 to 50 metres, with close to 150 world premieres and roughly 56,000 visitors expected across the six days. The show splits across two harbours: the Vieux Port carries motor boats, superyachts, rigid inflatables and technical services, while Port Canto holds sail, the smaller motor boats, water toys and the brokerage area.
Port Canto is the part that carries the market signal. It is where the pre-owned fleet is berthed, and where the half billion dollars of listed stock will change hands or fail to. The edition is also the first under newly appointed show director Constance Brement.
The autumn selling season in numbers
Two shows, sixteen days apart, carry most of the year's large brokerage business

Monaco Yacht Show
23 to 26 September 2026, Port Hercule
The read: roughly three in five yachts arriving at Monaco arrive with a price on them, and Cannes opens with more than 45 boats above 25 metres already listed. Supply at the top of the fleet is generous going into the season that sets most of the year's large deals.
Cannes figures: BOAT International (brokerage fleet), Yachting News (show scale). Monaco figures: Monaco Yacht Show fleet list, and BOATPro via Monaco Life for the for-sale count.
Monaco opens with most of its fleet on the market
The Monaco Yacht Show two weeks later gives the same picture in sharper form. The show's own fleet list puts 120 superyachts at Port Hercule by opening day, including 43 delivering in 2026, with the largest at 102 metres and an average brokerage length close to 49 metres.
The figure that turns a show preview into a market story comes from BOATPro, BOAT International's market intelligence platform. Of the 116 yachts examined in its preliminary fleet report for Monaco, 71 are listed for sale. On the numbers reported by Monaco Life, roughly three in five yachts arriving at the most exclusive show in the calendar arrive with a price on them.
A heavy for-sale book is not automatically a weak market. It can mean owners are confident enough to trade up, and the autumn shows are the accepted place to do it. But it does mean supply at the top of the fleet is generous going into the season, and generous supply is usually the thing that decides whether asking prices hold.
The half year said fewer boats at higher prices
The context for all of it is a first half that broke in the sellers' favour. AVNET reported in August that 281 yachts of at least 24 metres changed hands between January and June for EUR 4.05 billion, against 272 sales for EUR 3.61 billion in the same stretch of 2025, with the 50 to 70 metre segment up 52.9% from 17 transactions to 26. Volume moved barely at all. Value moved a lot, because buyers went bigger.
Set that pattern beside what is now on the docks and the autumn becomes a test rather than a formality. The market spent the first half proving that a small number of buyers would pay more for larger boats. Cannes and Monaco are where it finds out whether that appetite extends to an unusually deep book of large listings, or whether the same handful of buyers simply picks through a wider choice and leaves the rest on the market into the winter.
The behaviour is not confined to boats. The same narrowing has been visible across hard assets all year, including at the Monterey auctions in August, where total sales reached $755.6 million on fewer cars sold than the year before. Fewer transactions, larger tickets, more of the value concentrated at the top of the range.
Why an aviation title is watching a boat show
The two markets share buyers and, for two weeks in September, they share airspace. Nice Cote d'Azur is one of the busiest business aviation gateways in Europe through the summer season, and Cannes and Monaco sit within a short transfer of it. The show weeks are among the heaviest private aviation traffic of the Riviera calendar, and the flight departments serving them are frequently the same ones managing the aircraft owned by the people walking the docks.
There is a practical overlap too. Large yacht purchases and business jet purchases run through many of the same structures, the same jurisdictions and often the same advisers. Both markets have spent 2026 telling the same story: transaction counts flat to lower, average values sharply higher, and the strength concentrated in the biggest and newest assets.
What to watch over the next three weeks
Three things will show whether the autumn holds the first half's shape. The first is how much of the Cannes brokerage fleet is still listed when Monaco opens on 23 September, which is the fastest read on whether large stock is actually moving. The second is what happens to asking prices on the 50 metre and above segment, the part of the fleet that did the heavy lifting in the first half. The third is the split between the 43 new 2026 deliveries at Monaco and the pre-owned book beside them, because a strong delivery year competing with a deep brokerage listing is the condition under which used prices soften.
None of that will be settled by the time Cannes closes on 13 September. But the inventory is on the water now, and the size of it is the story going in.
