Modern whaling: the stern slipway, the factory ship and the 1930/31 Antarctic peak

evidence

The stern slipway, patented in 1922, was first taken to the Antarctic grounds in the factory ship Lancing in 1925, allowing whales to be hauled aboard and flensed in open water and beginning pelagic Antarctic whaling in earnest. In the 1930-31 season 29,410 blue whales were killed in the Antarctic, the highest single-season blue whale catch on record, with 41 factories and about 200 catchers operating and world production reaching about 3.6 million barrels; most Antarctic companies then declared a whaling holiday and production fell to about 775,000 barrels in 1931-32. V55 verification basis: retrieved in search summary; the sources retrieved render the patent holder's name inconsistently and no inventor is asserted.

A evidence is not a place. Drawing it on a map would assert something about the world that no stored fact supports.
