Hong Kong sits on the northern edge of the South China Sea, exposed to tropical cyclones from May through November each year. The Hong Kong Observatory issues an average of about 30 tropical cyclone warnings annually, with roughly 5 to 6 resulting in No. 8 Gale or Storm Signal. For yacht owners in Hong Kong, understanding typhoon season preparations is essential for protecting both property and the safety of others moored nearby.
The Marine Department requires all private vessels moored in Hong Kong waters to comply with typhoon shelter or sheltered moorings during No. 8 or higher signals. Owners must also ensure they hold valid public liability insurance to cover potential third-party claims arising during the mooring period.
Pre-Typhoon Preparation Checklist
Owners should begin inspections and reinforcement at least 72 hours before a tropical cyclone signal is issued. Quality nylon or dacron lines should be replaced every six months to minimise the risk of line snapping in strong winds. Storm lines should have a diameter of at least 25mm and be protected with chafe guards. All fuel and lubricating oil tanks must be securely sealed to prevent spillage.
Loose items on deck — including life rings, storage boxes, sails, and bimini tops — must be removed or lashed down with rope nets. The Marine Department recommends installing adequate fenders around the hull to prevent the vessel from striking the pier structure during sudden tidal surges. Given the high vessel density inside typhoon shelters, owners should allow extra bow and stern line clearance — generally an additional 20% of the vessel’s length beyond normal practice.
Electronic Navigation and Communication Equipment
Electronic navigation systems are especially critical during the typhoon season. GPS, radar, and VHF transceivers on board must be fully charged, with backup power sources readily available. The Marine Department’s Vessel Traffic Management System (VTMS) increases monitoring during severe weather, and owners can maintain contact with authorities via VHF Channel 16 or 67.
Hong Kong Typhoon Shelters and Mooring Arrangements
Hong Kong currently has five typhoon shelters located at Aberdeen, Shau Kei Wan, Causeway Bay, Cheung Chau, and Tuen Mun. Aberdeen and Shau Kei Wan are the most heavily used, but berth availability is often limited. Owners should consider booking a berth at least two to three days before a storm is expected, confirming all line and fender arrangements in advance.
Vessels intending to remain at a private mooring must ensure they have obtained written approval from the Marine Department and meet all safety conditions for private moorings. The Marine Department is clear that placing a private mooring in Hong Kong waters requires the written approval of the Director of Marine — placing a mooring without approval is an offence.
Boarding Prohibited During Typhoon Signals
During tropical cyclone signals, no one is permitted to board vessels moored in typhoon shelters or at private moorings. The Marine Department emphasises that during No. 8 signal periods, police vessels increase patrols, and any unauthorised crew or owner found on board may face fines or prosecution. Once signals are lowered, owners should return to their vessels immediately to inspect for hull damage and report any issues to their insurer promptly.
The Role of Professional Yacht Management Companies
Delegating typhoon preparation to a professional yacht management company is a popular choice among Hong Kong yacht owners. Professional managers are familiar with the tidal patterns and vessel characteristics of each typhoon shelter, ensuring preparations meet Marine Department standards while relieving owners of significant time pressure.

A: Yes. Under Marine Department regulations, placing a private mooring in Hong Kong waters requires the written approval of the Director of Marine. Operating a private mooring without approval is an offence.
Q: Can owners board their own vessels during a No. 8 signal?
A: No. During No. 8 signal periods, boarding vessels in typhoon shelters or at private moorings without authorisation is prohibited.
Q: How far in advance should typhoon shelter berths be booked?
A: Booking at least two to three days before an expected storm is recommended to secure availability.
