The first European traders, explorers, and settlers began exploring what is now Oregon's Pacific coast in the early-mid 16th century. As early as 1564, the Spanish began sending vessels northeast from the Philippines, riding the Kuroshio Current in a sweeping circular route across the northern part of the Pacific.

Some arrastras were powered by a water wheel; a few were powered by steam or gasoline engines, and even electricity. Arrastras were widely used throughout the Mediterranean region since Phoenician times. The Spanish introduced the arrastra to the New World in the 16th century. The word "arrastra" comes from the Spanish language ''arrastrar,'' meaning to drag along the ground.
