Analytical results are derived for the vertical force and pitch moment acting on a body of revolution which is moving with constant forward velocity parallel to an infinite horizontal wall. It is assumed that the fluid is ideal and incompressible and that the body is slender and situated close to the wall. The force and moment are given in terms of simple integrals involving the body shape and separation distance from the wall. Calculations are made for a spheroid, and it is shown that the vertical force rises rapidly as the body is brought progressively closer to the wall.
