Roaring Dan Seavey was a sailor that moonlighted as a pirate. He would sail into ports at night in order to steal other ships cargo while their crew slept. Seavey was also notorious for altering sea lights, either by extinguishing existing lights or placing false lights. The trick, known as "moon cussing," would cause ships to sail into rocks, where Seavey's crew could easily capture the cargo from the wounded vessel. they could just simply double cross her later.
