When we were planning this month’s trip, I had considered heading down the River Avon, either for a short jaunt, or possibly as a traverse to join the River Severn and on towards Gloucester. The navigation is operated by the Avon Navigation Trust (ANT) and requires a separate licence. I found from the ANT website that they published a spiral bound guide to the river, which had detailed charts. I decided that was worth having on board. I also signed up for their navigation alert email list. That is how I knew that the river is currently at FLOODCON 3 – which means “Tie up at a flood-safe mooring and don’t leave your boat without wellies.”
