This paper is a general description of the cable layer “Toyo-Maru”, which was recently built by Kawasaki Dockyard Co., Ltd., Kobe, for the Department of Communication of our Government.
In the former part of this paper, the general arrangement of the ship and construction of the hull are refered; and in the next part, the cable handling apparatus and their arrangement, to which various installations are properly deviced and attention is paid to make them fit to the modern submarine cable.
In the latter part, the propulsive machinery is described. It is worthy of note that the new ship is provided with two sets of double reduction geared turbine and one set of Voith Schneider system of propulsion; the latter, however, is prepared rather for the purpose of manoeuvering the ship during cable laying operation than for the propulsion of the ship. The principal dimensions are as follows.
Length over all……121.02m Load draught……6.34m
Length between perpendiculars 102.25m Gross tonnage……3, 718.73t
