How did decked fishing vessels change Icelandic fishing in the 19th century?

In 19th-century Iceland, the introduction of decked fishing vessels was a significant technical innovation that transformed the industry by enabling fishermen to operate farther offshore than was previously possible with open boats.1

Despite this advancement, the transition was gradual; at the beginning of the 20th century, more than half of the annual catch was still being taken in open boats. This development occurred during a period of economic stagnation in Iceland, which stood in sharp contrast to the country's high level of political activity as it struggled for independence from Denmark.1
