The procedure required for entering Apra Harbour in which the MYC is located is to call US Coast Guard on VHF 16, advise of your arrival ETA preferably 12/24 hours before, then contact Port Control on VHF 13 advise of your intention to enter and await permission to proceed to the club. This is principally required because the course through the harbor is amongst various navy anchorages and defense training areas. A U.S. Coast Guard vessel will probably shadow you into the anchorage.

Also see Apra Harbour.


ARRIVAL: Proceed to the anchorage directly opposite the Marianas Yacht Club (Apra Harbour). No less than three members of the club (two board members) waded out to help us beach. They will advise the authorities who will come to you. DEPARTURE: Proceed to the Apra Harbour Complex where Immigration and Customs will issue your exit documents.

Not a problem.


Guam has four main areas for yachts to stop whilst there - the MYC, the Agana Marina, the Agat Marina and the harbor of refuge. Both the Agana and the Agat Marinas have no space for a cruising yacht. Agat in particular we would consider unsafe anyhow should a typhoon come Guam’s way.

The harbor of refuge is a facility owned by the government of Guam for the use of vessels in times of typhoons … and it pays to remember this island is the gate to Typhoon Alley.

The special harbor has space for about thirty vessels arranged in a grid. On the sea floor are situated large concrete blocks with rebar hoops to which one can shackle ropes to hold the vessel in position.

During our stay typhoon Kong Rey caused a flurry as the island went on the alert. We were assisted to the harbor by club members Chris and Cindy Bell. Through the club’s facilities we were able to borrow eight sets of shackles and thimbles with which to make Shadow of Lorelei secure. The typhoon fizzled.

Behind the harbor of refuge is a ‘marina’ facility run by the port a where occasionally a space might become available. This is basically a shallow area where you can tie to the shore and a buoy aft, but provides no water or electricity. (Contact Bree at the port administration 671-688-6488)

Guam is expensive in some supermarket items but cheap in others. All in all it is a good location for those wishing to provision with Western goods prior to continuing on to Japan or the Philippines. We found the PayLess supermarket chain (various locations) and the California Mart (at the GPO complex) to be the best priced and freshest produce.

For retired defense force or government personnel, base rights might be granted at the Polaris Point Navy Base or Andersen Air Force Base where there are well stocked PXs. We did not qualify for entry so the information is from locals.


  • Direct flights to the US mainland, Asia and Oceania are available from the international airport.

Guam is an island in the western South Pacific Ocean, about three-quarters of the way from Hawaii to the Philippines. Archaeological evidence indicates that the island was inhabited as early as 4,000 years ago, settled by people of Indo-Malayan descent. The first people on Guam braved the vast waters of the Pacific Ocean in relatively small canoes, eventually settling throughout the Mariana Islands.

  • Anyone who doesn’t have all their charts for the areas surrounding Guam, the MYC has a treasure trove of charts many of which are doubles and may be accessed with permission.
    On the fun side of things there’s lots do here, culturally and physically. Diving, snorkeling, water sports, skydiving, nature walks, rugged or serene beaches, coral lagoons, World War II memorial sites, dining, several movie theatre complexes, good bookstores and so on. On Wednesday nights the Chamorro people, original inhabitants of the island, put on a fiesta and market at the Chamorro Village, with a wide choice of food stalls, local artifacts and general paraphernalia topped off by a dance performance by the local youth groups. Worth a visit.
    For those who require internet facilities there’s the G3 group with outlets at the Agana Shopping Centre and Micronesia Mall, free wifi at several coffee shops in Agana, Tumon and Tamuning, wifi in the lobby of most of the upscale hotels. At times the members of MYC might help out by allowing one to use their home facilities.
