Happy to see that the boat was easy repairable!
Other most likely had lousy days for model boating. I've see/had sinkings, collisions, drops (especially on concrete), loss of electronics on the water (batteries, connections, RC gear), weed entanglements, as some examples.
"Not a good day" is a good topic for some more feedback from members, so...
