As I was thinking about possible issues that could occur during my river trip, an idea occurred to me. In the case of light winds, perhaps I could utilize the river’s current to help pull me downstream, and it turns out there’s a commercially available device that could work for that, the drift anchor. It’s actually meant to keep a boat’s bow pointed into the waves in the case of losing power in rough weather. What I am hoping to do with it is use it in reverse.
It looks pretty rough, and it should. This is more of a prototype at this point.
