Ship's Log

I was never diligent about keeping a ship's log for inland and near coastal (less than 25 nautical miles from shore) sailing. In my opinion, detailed hourly position reports in a log simply doesn't make sense for day sailing, or port hopping. Even updating a log every 4 or 8 hours with position and various other data points is not very useful unless you collect amounts of data over a long period of the same area. So, my approach to logging employs modern technologies and a daily narrative of events.

The technologies I use are Automatic Identification System (AIS) and Iridium Satellite Communications, and the daily check-ins on the marine/ham SSB radio via The Pacific Seafarers' Net. AIS updates my position once daily, and can be found on websites such as Marine Traffic. The Pacific Seafarers' Net tracks my position and other data once daily. Finally, the Iridium Go system updates my position underway every hour, and plots my track on my Predict Wind Internet page.

The narrative portion of my log are the posts at least once per day to my Predict Wind tracking page on the Internet and uploaded via the onboard Iridium Go system. I find the narrative makes for more interesting reading by others and provides a way to share my experiences, my thoughts, and important events aboard the boat.
