NGA Philippines, Celebes, Java, Banda, Japan, Yellow and China Seas, and Gulf of Thailand Nautical Chart

The maritime region stretching from Southeast Asia to the Far East is one of the world's busiest and most complex navigation areas. Covering strategic waters such as the Philippine, Celebes, Java, Banda and Japan Seas, the Yellow Sea, the China Seas and the Gulf of Thailand, this region combines narrow straits, remote archipelagos, tropical waters and major international shipping routes.

Nautic Way Maritime Bookshop offers a specialised selection of documentation produced by the NGA (National Geospatial-Intelligence Agency), providing essential resources for modern navigation in these waters. These reliable technical resources, regularly updated, provide leisure sailors, fishermen and professional mariners with precise support for planning routes and manoeuvres safely. Choosing the right chart for this region is essential not only for accurate route plotting, but also for meeting regulatory and safety requirements when navigating offshore or in coastal waters in areas where local documentation may be limited.
