How many ships did Britain maintain in South America related to the seal economy?

The reason for selecting the figure of 70 ships relates to Britain's historical engagement in the seal economy, particularly during the 19th century. During this time, British interests, particularly in the Falkland Islands and surrounding coastal areas, led to the establishment of a substantial maritime presence to support seal hunting operations.

The maintenance of 70 ships indicates a significant commitment to safeguarding the seal hunting activities, which were economically important. This number reflects not only the scale of the operations necessary for such a resource but also the strategic importance Britain placed on ensuring that these economic interests were protected from competing nations and to support the livelihood that depended on seal hunting.

The other figures provided are not consistent with the documented maritime presence of Britain in South America related to this specific economic activity during the period in question.
