In this paper, optical problems of sun following on the sea is discussed. Main difficulty is that angular velocity of the raft is very large when the sun passes near the zenith. This difficulty is released by mean of adequate rotation of raft that reduces the angular velocity and minimizes the loss of incident solar energy resulting from sun following error.Furthermore, some formulae for sun following that is necessary to use in the third and the fourth reports are showed, for example, raft angular velocity, acceleration, moment, power, and energy for raft rotation etc.
