"Boats gather Food from Fish and Coin from Whales faster."
Gill Nets is a technology in Age of Empires III that can be researched at the Dock. Once researched, it increases the gather rate of Fishing Boats, Caravels/Galleys/War Junks/Fune, Canoes, War Canoes, Tlaloc Canoes, and Marathan Catamarans by 15%. Long Lines is the further upgrade of this technology.
- Note: All canoes and the Marathan Catamaran have a base gather rate 2.5x slower than other vessels. See Food and Coin for exact totals.
