Thanks to Maranatha guide, Soggy Paws PNG Compendium: their notes are summarised in our own words.
This guide is a set of personal cruising notes shared in good faith. Information can be out of date or wrong, and positions can be out by hundreds of metres. It is not a substitute for official charts and notices, your own eyes, local knowledge, or professional medical, legal or customs advice. You use it at your own risk: the skipper alone is responsible for the safety of the vessel and everyone on board, and the authors accept no liability for any loss, injury or damage arising from its use.
