Sailfish are a type of fish found at the Deep Sea Fishing hub. They are also featured as fishing spots found in the northeast corner of the platform. They do not require any bait, and require 97 Fishing to catch. There are two standard sailfish spots, and like most fishing spots, they change location every few minutes.
Alongside regular sailfish spots, there are also swift and calm sailfish spots. A swift sailfish spot is always found near the regular ones, and lasts a shorter amount of time, but boasts a higher catch rate. Calm spots spawn rarely, and last a longer amount of time, but have a lower catch rate.
