UK heatwave turns canal boats into 35C ovens

UK heatwave makes life on canal boats unbearable, with steel houseboats reaching 35C and residents comparing them to ovens. Permanent resident Wayne says his 60ft Oxford Canal boat with baby daughter hit 35C, retaining heat well into evening. Nathan Sherlock at Tooley's Boatyard says cooling steel boats is a huge challenge with no good answer. The Canal and River Trust estimates up to a third of 35,000 boats on England's waterways are permanent homes; steel retains heat, helpful in winter but not in a heatwave.
