Introduction

Guam is the largest island in Micronesia and an unincorporated territory of the United States, sitting at the strategic crossroads of the western Pacific. For trans-Pacific sailors it is one of the most significant waypoints in the region — a fully American destination with US customs and immigration, excellent provisioning, English spoken everywhere, and genuine big-ship harbour infrastructure at Apra Harbor. The island stretches 50 km from the dramatic limestone cliffs and beaches of the north to the rolling hills and mangroves of the south. Guam's indigenous Chamorro culture — blended over centuries with Spanish colonial influence and American modernity — gives the island a unique character found nowhere else in the Pacific. The sailing approach from any direction is straightforward: Apra Harbor is deep, wide, and well-marked. Typhoon season (June–November) brings real risk — Guam has been struck by severe typhoons — but Apra Harbor's inner basin offers good shelter and the US military infrastructure provides up-to-date weather services.

Protected Anchorages

Apra Harbor is Guam's main port and the centre of yachting activity. The inner Apra Harbor (also called the Inner Harbor or Cabras Island area) is protected by a long breakwater on the north and the peninsula on the south. The Agaña Boat Basin (also spelled Hagåtña Boat Basin) on the northwest coast is the primary small-craft facility — anchor or pick up a mooring in 3–8 m over sand and mud, good holding. VHF 16 is the working channel; contact Marianas Yacht Club on VHF 16 or by phone. Apra Harbor's commercial areas are off-limits to pleasure craft without a permit; keep clear of Naval Station Guam waters — the restricted military zone covers much of the southern harbor. Fuel (diesel and gasoline) is available at the Agaña Boat Basin fuel dock and at the commercial marina. Water, electricity, and basic facilities are available at the boat basin. For typhoon season: the mangrove channels of Apra Harbor's inner reaches and the sheltered berths at Marianas Yacht Club offer the best protection — consult club staff well in advance.

Customs Protocols for Visiting Yachts

Guam is a US port of entry subject to full US Customs and Border Protection (CBP) and US Coast Guard procedures. All arriving vessels must contact US Coast Guard Marianas on VHF 16 prior to arrival and receive clearance instructions. Flying the Q flag is required. CBP maintains a presence at Apra Harbor; vessels should proceed directly to the CBP dock on arrival. All crew require valid passports; US visa rules apply — many nationalities qualify for the Guam-CNMI Visa Waiver allowing stays up to 45 days. US biosecurity (USDA APHIS) is strictly enforced — declare all food, plant, and animal material. Agricultural inspectors will board the vessel. No fruit, vegetables, or meat from outside the US mainland may be brought ashore without inspection. Departure to non-US destinations requires a CBP outbound clearance.
