2013 Nautical Almanac download. This is a computation, not copy of the official book. It should match the data, but you should spot check it to be sure. There is similar data at navsoft.com, but theirs cannot be printed, this one can be.
Nautical almanac Increments and Corrections valid for any year, from navsoft, but we have our own compilation of this in our online resources if this one goes missing. Ours is images of actual NA, theirs is nicer looking pdf.

Logbook (135 kb pdf) for recording required inspections, drills, and other data.
For an actual Navigation logbook see our Sailors Logbook

This link is not consistent with the others, it is also in our marine weather links, but it is too important and it seems maybe too over looked, so we have to stress it whenever we can. We have this archived, so if the link goes missing, let us know. Tropical storm safety and the Mariner's 1-2-3 Rule
Since we are not being consistent, here is a nice link from our weather resources PAC NW and Inside Passage Weather
