Port Hercule
Port Hercule de Monaco
Monaco-Ville / La Condamine, Monaco · 43.735°N 7.426°E
The principality's deep, breakwater-protected yacht harbour and the operational heart of the Monaco Yacht Show. Night entry is controlled, megayacht quays are scarce, and September occupancy is a planning problem rather than a berth search.

Conflicts in the ledger
Maximum LOA
Operator materials and captain reports disagree on whether 140 m is a hard limit or a typical planning envelope. Treat as REPORTED and confirm the specific quay.
