In the course of exploring Guam we have found two possible marinas for yachts.

There are four but one is the commercial marina on the way to town which is yacht hostile from what I hear. Not a perfect setup for a yacht either. It is really a working marina for all of the tourist para gliding boats and what not.

The marina in the harbor of refuge has no wind and is more of a parking spot for off duty work boats. It would be very buggy and I doubt you could arrange a long term stay if anything.

Agat Marina (pictured) is a real marina and the only problem with it is that it is pretty full from the looks of it. There is a wonderful marina in side the harbor at the Navy base but you have to have a base pass to reside there. It is a nice spot though and could cause you to consider joining the Coast Guard Auxiliary.

Tamio San on Dharma arrived at MYC today. Tamio San is Japanese and is just wrapping up a circumnavigation with huge ocean passages at every leg. It is interesting to note that Masa San on Nuk, Tomio San on Dharma and Fuji San, still inbound on Seagull, are all single handers.
