    Default Navigating without a log

    Son took a tug across from the Clyde to Northern Ireland. His nav was completely dependent on GPS.

    When chastised, he told me no tugboats have logs. He had a compass but couldn't read it as the dome was obscured.

    He became stroppy when asked what would happen with a GPS outage.

    Not having a log was nothing unusual years ago but no useful compass is daft imho

    Doesn't surprise me that they don't have a log. The MCA would probably take a dim view of the unusable compass even though I'm sure tug skippers practically never use them.

    It's a matter of risk and mitigation. The more your son does not know, the more he has to be careful. This could mean only navigating in perfect visibility with a reliable weather forecast. Nothing is absolute: log, compass, paper or even approved navigation systems.

    I would have thought that the compass was necessary as it does actually rain a lot on that passage and steering a straight line over a few miles without visual references is difficult.

    That could be. I learned to sail on my father's boat in and around Vancouver, BC. We cruised for weeks at a time and the only log was a bit of wood on a string that got pulled out once every couple of years to see how it worked with a stopwatch. We used a compass a lot, but when you can navigate by sight, you can easily get by without a log. Particularly if you have a pretty good sense of approximate boat speed.

    Someone will be along to say that he will have had a compass and a GPS on his phone, and maybe charts too.

    We haven’t had a reliable log in 9 years of sailing or current boat and haven’t really missed it.
