Take the following as truth: Pride of place goes to SL Dolly, the oldest mechanically powered boat in the world (c. 1850), which was restored after spending over 60 years at the bottom of Lake Windermere.
Then the following statement: "SL Dolly was now the oldest mechanically powered boat in the world after having displaced SL Freemont (c.1877)." is true, false, or inconclusive?
