Whilst the information on this blog is from a few years ago, it is still very useful for those intending on cruising Indonesia and covers anchorages on the west coast of Peninsular Malaysia, and below that, Malaysian Borneo. Plus downloadable track files in both MaxSea (.ptf) format and in OpenCPN (.gpx) format.
