IN the last issue of this journal it was shown that the take‐off performance of seaplanes can be influenced greatly by design without adversely affecting the air performance. The various factors to be considered in an estimation of the take‐off performance were enumerated and typical curves of effective thrust, T', reaction drag, DR, and air drag, Da were given for a weight well below the limiting take‐off weight. It is shown in this part of the paper that there are two critical speeds and that failure to take off occurs at the lower of these speeds in some seaplanes and at the higher in others.
