Yesterday’s listener question was about a tugboat helping out a big ship in the Astoria Anchorage. That tug, the PJ Brix, by the way, is owned by Foss Maritime, a big presence in the tugboat world. Since we see fewer tugboats on the lower river compared to upriver vessel traffic, I thought today we would talk about the huge role tugs play in upriver commerce. In many cases, it could not happen without them.
