It is recommended to pick up a tourist guide before arrival and study the countries culture and history. Even in rain or on a speed boat it is always comfortably warm. There are several carpentries and other workshops as well as some hardware stores. Prices in general are below US standards but don't expect any give-aways. Mostly everything in Male needs to be imported and is accordingly pricy.
Local goods are fish, fish, fish, bananas and coconuts, betel leaves and nuts.
If you're into scuba diving or snorkeling, this is the place. Bring your own, buy it locally or rent everything you need. If you can find some time, it is well worth spending it on one of the close islands, Male itself does not have a beach.
