Hiring of the steersman becomes available to the player from 50th level in the store in the bar. A player can hire only one steersman. The steersman is gaining experience similarly to the player, so the sooner a player will hire the steersman the better for him.
The steersman gets experience at the rate of 1:1 with the experience of the player. With the accumulation of experience by steersman he can "pass retraining", to increase his stats for a certain amount of money.
