In 1998 while a house boat was in the lock the main up river gate unexpectedly opened at speed and a wall of water rushed in filling the lock in an instant. The house boat was smashed and sunk and the lady owner drowned in the swirl of water. Thankfully the cause has been rectified and this can’t happen today but the thought did go through my mind what to do if the water rushed in. You now have to wear life jackets (PFD) in all Rhone locks.
I hope I have captured the feeling in my youtube video here Youtube video
Having had to wait at both lock we were behind schedule and did not want to rush to reach Viviers so we gently cruised past the Macoule nuclear power station that provide most of France with electricity. This one was completed in 1956 and is still going strong cooled by the water of the Rhone. We tied to the banks of the Rhone at two pylons and settled down for the night to be disturbed by a very large barge racing to get to the Bollene lock before it closed for the night. We rocked and rolled at the wake washed past us.
