A problem of computing the visibility of a rather large submerged object in case of visual observation from the given height over the sea surface is considered. The developed algorithm requires a minimal ob-servation conditions data set: the object parameters, the solar angle, the horizontal visual range, the wind velocity, and the Secchi depth. A procedure of computing the visibility range, taking into account surface roughness influence, is given. Some examples of visibility range computations for objects of minimal size 10 and 20 m under given meteorological conditions are given as well.
