Diana was a whaling ship built in 1840, in Bremen, Germany. She sailed out of Hull, England. In 1858 a steam engine was installed, making her the first steam-powered whaler to sail from Hull (Tay from Dundee was the first ever, a year earlier). Records held in Kingston upon Hull, claimed that the steam engine was installed in Diana in 1857, and, according to Dundee websites, in Tay in 1859.
