While crusing north of Sitka, AK we observed a logging operation where a helicopter would ferry logs from the hillside to this waiting ship. You can see one log beling lowered in this photo.
These fishing boats are known as purse seiners after the type of net they are using (purse seine). In this picture you can see the net coined on the deck.
A fishing boat plays out its purse seine net. The bigger boat is pulling away from the smaller skif, and the net is coming off the deck.
