Across the summer's published AI-visibility rankings of luxury destinations, Monaco placed thirteenth. On the water we measured, Monaco led every harbor we fence with 419 identified yachts, ahead of Saint-Tropez (352), Porto Cervo (316), Cannes (308) and Antibes (278). That puts Monaco 19% clear of second place and 51% clear of Antibes. Attention and presence are different instruments, and only one of them is measured.
METHOD · DISTINCT IDENTIFIED YACHTS 24M+ PER FENCED DESTINATION, JUN 15 – JUL 29 2026, VS PUBLISHED THIRD-PARTY RANKINGS
Among 481 yachts we tracked in both the 2025 and 2026 summer seasons, boats that shifted their season westward outnumbered those that shifted east by roughly three to two. Exclude the eastern Mediterranean altogether, the region our receivers reached latest, and the margin widens rather than narrows, to 94 against 54. The Mediterranean's summer, measured hull by hull, moved west.
METHOD · SAME-BOAT MEAN FENCE LONGITUDE, SHIFT > 2°, IDENTICAL JUN 15 – JUL 28 WINDOWS IN BOTH YEARS
While the rankings argued about which destination was fashionable, Porto Cervo filled. Across the final week of July the marina held an average of 28.5 yachts of 24 metres and over at any given hour, against a June norm of 11.8, and peaked at 43 on the evening of the 26th. Over the summer window it finished third among all the destinations we fence, ahead of Cannes and Antibes.
METHOD · CONCURRENT YACHTS 24M+ IN PORT, HOURLY MEDIAN PER DAY, MEAN OF 22–28 JUL 2026 VS MEAN OF 16–30 JUN 2026, COVERAGE LEVELLED
We fenced Bergen, the Sognefjord, Copenhagen, the Hebrides and Alaska and measured three summers of large-yacht presence. The result is flat: the northern rush exists in editorial, not yet in arrivals. We publish the negative finding because a measurement company that only reports surges is an advertising company.
METHOD · YACHTS 24M+ ABOVE 55°N, SAME SUMMER WINDOWS 2024–2026, FERRY AND CRUISE TRAFFIC EXCLUDED
The two newest fleets on the fifteen-house league arrived with the lowest movement on the board this fortnight, while the Mediterranean front-runners ran at more than double their pace. One fortnight is weather; a season is a market. The league publishes weekly either way.
