Victor Wejer produces each year a Yacht Routing Guide for the North West Passage for the current season. This provides up to date information to supplement that in the RCC Pilotage Foundation book Arctic and Northern waters. Victor has posted the new 7th edition Guide to Northwest Passage for 2020 under the new name of Periplus to Northwest Passage signifying the reference to the old sailing directions and rutters. It has revised some pointers and added updated information.
The current version of the guide is available as a free download from the RCC Pilotage Foundation using the link below.
