When we bought the boat its anchor rope was about 150' long. Plenty for the Willamette, but too short for the Columbia.
This week we got 600' of 9/16" Dacron rope... really nice stuff.
300' is typical for the Columbia, to give plenty of play in the heavy current and various riverbottoms.
Here is the new rope ready to deploy! Fall fishing we are usually at 55-60' deep, and will use about 200', so we'll wrap up and stow the extra rope with the red/white bouy to keep it out of the way.
Lets hit the river!
