The paper proposes to minimize the average altitude of the ekranoplane due to the desire to circumvent the low-periodic components of sea waves with smooth vertical maneuvers. To evaluate the effectiveness of the proposed method for optimizing the trajectory, a model was developed consisting of four blocks: simulation of sea waves, simulation of the operation of the measurement and control system of a ekranoplane, modeling the dynamics of the movement of an UAV, and evaluating the effectiveness of altitude minimization. The simulation results showed the possibility of reducing the average altitude of ekranoplane by 0.65m in 6-point sea waves. Also, the overload caused by vertical maneuvers did not exceed 0.16 g, which is acceptable for the transportation of most goods and people
