You do have a fair point. Most of the bigger hire companies have got so many boats being turned around they dont have the time to show them how to work locks etc. ESP with the Llangollen if you hire from Anglowelsh at Trevor or black prince at Chirk abc at Ellsmere there are no near locks for them to take the hirers through. So when theses hirers get to the locks they just use it as they think. Which is wot I done when we first hired from Ellsmere back in 2007 but I'd watch videos on YouTube & online advice so knew the dangers and briefly how to work them
