best bet is to watch and see if the clouds are moving at sea, close to shore, you'll see the movement. For a take off in these conditions, I've found a set of peddals to be an absolute must. Rudder control is key to a successful take off when the carrier is turning. It can be done using the keyboard, however, your takeoff will NOT be pretty. But most of the time, without peddals, you'll be in the drink 9 out of 10 times while the ship is turning
