You could try, Others have and failed. If you walk out far enough to clear the shallows you might get away with it. It just depends on how much weed is floating about at the time. I sailed last year with a thruster but still caught a lot of weed and in close could not sail at all, You really would not want to catch a weed patch with a big freeride fin.....But your biggest problem will be hitting the bottom

...It's shallow through most of the run.
