I had to cut my 3rd practice derby short due to a broken rudder bracket. At least I was able to figure out I had the problem and get to a beach to make some kind of jury-rig to then enable me to get back to the launch place. I was looking forward to going 20 miles, though. Perhaps next time. At least the rudder bracket failed in a practice session and not the actual race. I’ll have to make a replacement bracket part and then make a 2nd one as a spare to keep in the boat.
