Developed in the 10th Century, Sea Hawks were similar to battleships. Long and fast, they typically were between 150 and 200 feet long. They displaced around 100 to 150 tons. Standing at 20 to 30 feet high (beam) – Sea Hawks too incorporated the “wing stabilization” technique to help with keeping the ships upright. Sea Hawks were among the first Chinese vessel to NOT incorporate Oars and relied strictly on sail. Longer and more slender that the wider ships in the Chinese Navy, they were akin to the European Corvette. Sea Hawks also used “fire weapons” (to include chemical) as their weapon of choice. Sometimes called “Fire Hawks”, these were truly “unique” ships.
