Abstract : A computer program for simulating the performance of the 100-B surface effect ship is used to study the longitudinal motions of the ship under various wave conditions. An investigation into the effect that waves have on bow seal, stern seal, and plenum pressures is conducted. The relationship between the different pressures and their associated requirements of input air from the fans is studied. It is concluded that the computer program is limited to a certain range of speeds. The concept of the ship capturing air to reduce drag and increase its speed is questionable due to the rapid replenishment of air required to keep the ship riding on its bubble of air.
