The map
224 yachts at their last recorded position — 105 in port, 97 at anchor and 22 underway. Positions are rounded to roughly 100 m and refreshed with the record, at most hourly: a snapshot as of , not a live feed.

Overlapping yachts are spread slightly for legibility — within a harbour the dot marks the port, not the berth. Yachts unseen for more than a day are not shown. How positions are published.
