I was looking to see if there was anyone who sailed on tow boats on the Columbia River and had some information. I’m on a ship that comes into Portland once a week so I’m familiar with the various companies that are up there but I just wanted to get some more info.
The Columbia river will give you inland time. Foss, shaver, tidewater, Bernert, sds, and Olympic are the players on the river. Foss only does assist and Olympic works lower river. The other 4 work up to Lewiston. You will also see sause and brusco. If you want coastal time go with one of them but they aren’t really Columbia river companies.
