The UK Hydrographic Office (UKHO) are planning a new edition of ADMIRALTY Ocean Passages for the World (NP136).

First published in 1895, this publication is designed to support mariners in the planning of deep sea voyages along major trade routes, with details of weather, currents, ice hazards and other environmental features that may be encountered in transit.

Ocean Passages for the World (NP136) supports the planning of deep-sea voyages on most major routes, with details of weather, currents, ice hazards and distances between major ports.

Members of IAIN are encouraged to complete this latest survey as soon as possible to ensure that small craft users and others do not lose the sailing route information used for ocean passage planning purposes that was formerly included. The survey, which is being run by the UKHO, should only take about five minutes to complete and can be found here.
