This article presents the problem of overloading of the steering gear controlled by an autopilot in high sea states and ways of reducing it. The author proposes a new method of estimating the steering gear load by counting the number of machine reversals in a selected time period. A block diagram of such solution is presented along with the results of simulations of system operation in different sea states. The results obtained, in terms of number of reversals, depend significantly on the state of sea, providing a means to estimate the current state of the sea as well as the expected difficulty in exploiting the steering gear.
