The long boats seen in Horta harbour are the original whaling boats that put to sea up until the 1980’s. They were towed out by the launch to wherever a whale was sighted, then rowed or sailed sometimes for hours, and when a whale was in range drew alongside. The harpoon expert threw from the bow and the attached line ran out through the slot seen in the bow.
After a messy fight the motor launch would drag the whale back to a holding buoy just before the whale factory. At it’s peak in about 1952 about 160 whales were processed for oil and fertilizer.
