Testing complete and classified as successful! Taken this afternoon at Georgetown, CO, about 45 miles west of Denver and at 8,500 feet. I was going to put the boat in the water but there were not any good places to float it from. The canoe appeared to just sit in place. There was no noticeable movement at all. I'm going to tweak this project with a few small adjustments but I think I can call this one 'good.' Looking forward to two days on the water in a couple of weeks.
