1830 was the worst year in the Greenland Fishery. There were 91 British ships in the Davis Straits that year and 19 of them were lost, most of the others were damaged, and 21 returned without catching a whale. Details are in Basil Lubbock's book 'The Arctic Whalers', which, although it gives much detail about the whole of the fleet, fails to mention a whaler called Diamond, (Eliza Swan, Rattler and Resolution are mentioned).

It was a bad year for Hull (the major contributor to the whaling fleet). We lost 6 of our 32 ships.
