The effect of fouling upon the resistance of ships was examined by the towing experiments with the ex-destroyer Yudachi at various stages of fouled surface after 4,75,140,225 and 375 days out of dock ; the speeds experimented with were up to 20 knots at each fouled condition. After these experiments the author studied the effect of fouling on the propulsive efficiency applying the above-mentioned results of towing experiments to the trial results of a first-class destroyer. The chief conclusions drawn from these investigations are : (1) Frictional resistance of ships having fouled bottoms can be expressed by the following formula : -R_f=f S V^<2-1>, where R_f=frictional resistance in kg., S=wetted surface area in m^2., V=speed of ship in knots, f=coefficient of frictional resistance which varies with the weight of fouled substances per unit area as shown in Fig.6. (2) Propulsive efficiency is affected scarcely by the bottom fouling.

The first part of the paper deals with the combination comprising a triple expansion engine, with poppet valves for high and intermediate pressure cylinders, and direct coupled to the main shaft line, and an exhaust steam turbine, to utilize the energy contained in the exhaust steam from the engine, double reduction geared to the main shaft line. In this system, the turbine is to work for ahead direction only; an automatic friction clutch is to disengage the turbine when the main engine is to run in astern direction.Mechanical regilient coupling composed of friction disks and a number of coil springs is contained inside the first reduction gear wheel, and is arranged to take off uneven torsional shocks taking place due to the action of the crank shaft of the reciprocating engine.In the second part, description is given about the combination consisting of a set of double compound high speed engine, single reduction geared to the main shaft line, and a low pressure turbine, double reduction geared to the same line. In this case an astern turbine is also arranged. The exhaust steam from the engine is controlled with special manoeuvering valve to enter into either ahead or astern turbine as desired and the valve is to cooperate with the reversing mechanism of the reciprocating engine.Particulars of the ships having these systems of combination machinery are given in the attached table also the performance data of their maiden voyages are given in another table.A sketch of the design of the machinery space of twin screw engines and its brief description is given in the last part of the paper.

It has elapsed many years since the water tube boilers were introduced into marine use, with full success in European countries and in America. In Japan, on the contrary, this type of boiler has been used for some large cargo ships before the war and for a few kinds of War-time Standard Type of Ship under instruction of the former Japanese Navy during the war, but now no positive demands.It is generally recognized that through the possibility of high pressure and high temperature steam usiug the water tube boiler, the higher thermal efficiency and weight reduction in total engine part are gotten. This fact mokes us profitable to adopt the boiler in this country where fuel and steel are excessibly short. Nevertheless, there are hesitations in our ship world to adopt this type for marine boiler due to li anxiety of reliability and difficulty of handling.The prob ems on reliability and difficulty in handling. are as follows;(1) Danger of low water, (2) Trouble through feed water, (3) Easiness of coal burning.In this paper, the above problems should be investigated to clarify the reality, and if possible new design on the water tube boiler and finally the remedy to so ve these problems will be protested.

The “Argentina Maru” is the first motor passenger and cargo ship to he constructed under the special Shipbuilding Subsily of the first grade grented by the Japanese Government, and this magnificent Round-the-World Liner is wholly of Japanese construction and materials. In vi w of these circumstances, it seems to be appropriate to make some reference to the ship; therefore a general description of the vast design, construction, equipment, etc., is given in this paper.

The antarctic whaling tanker, “Nisshin Maru” (22, 000 tons deadweight) was successfully built on 28 th Sept. '36 by the Kawasaki Dockyard Co., Ltd., Kobe, in the record of only 216 days from laying down of the keel to the delivery to Messrs. Taiyohogei Kabushiki Kaisha.The vessel is the largest tanker of its kind ever built in Japan, and the following dates indicate the extraordinary speedy program at which she was built in such a short period.The contract signed 28 th, November, 1935.The keel laid 26 th, February, 1936.The launching 1 st, August, 1936.The official trials 14 th, September, 1936.The Delivery 28 th, September, 1936.There were many difficulties which they had to overcome, such as : difficult construction on an ordinary building slip not well arranged with up-to-date crane equipments, unusual short time limit of construction, and hardship of prompt collection of materials, etc.They laid down therefore a strict schedule so as not to delay the delivery and by good luck, it was faithfully obeyed by the men of all departments of the Dockyard Co.Combined with the mutual co-operation of all men and proper supply of all necessary materials, the schedule was very satisfactorily carried out in good order.On the other hand, special attention wa so pa to the working hours as well as labour shifts so that the workmen should not be overworked either mentally or physically.Thus their earnest efforts have at last produced good results with such an epoch-making record of speedy ship building which has never been experienced in the world.In addition, this vessel adopted the “Isherwood Bracketless system, ” the simplicity of which has proved a good effect upon such a quick work as “Nisshin Maru.” The principal dimensions are as follows : Length over all…550'-0''Length between perpendiculars…535'-0''Breadth moulded…74'-0''Depth moulded to upper deck…48'-9''Load draught…34'-25/16''Gross tonnage…16, 764 tonsDeadweight…22, 000 tonsMaximum speed…14'5 knots

The completion of the M.S. Tatsuta Maru, the sister ship of the Asama Maru and the biggest motor liner of almost wholly a Japanese production, is an important event for Japanese Shipping and Shipbuilding. On this remarkable occasion, it does not appear to be wholly nonsense to make some reference about these ships. In this paper, a short review is made about the vast designs and long efforts to arrive at the final elaborate design of the Pacific Liners. Some results are also picked up from those of the exhaustive trials, and finally, an attempt is made to lay out 2,000 B.H.P. geared Diesel installation for a high speed Trans Pacific Liner which might come into question in future.

It is a well known fact that oil tankers in loaded conditions sustain severe sagging stress on top-side member in rough weather. The motor tanker “San Diego Maru” encountered extremely rough seas in Pacific Ocean during a winter voyage, resulting severe bucklings and some cracks on the upper deck plating and also upper strakes of longitudinal bulkheads in midship portion. The author analyses the causes of the damage referred to, describing her general longitudinal strength among waves, the effect of impinging water on decks, together with some investigation on the theoretical buckling stress on deck plating stiffened with beams of comparatively light scantling.

The auther briefly touches, in the first place, on the signifieation of "Air Conditioning, " its origin and development ; and describes on air conditions v.a.v, human susceptibility. Then he generally exp'ains the methods of conditioning the air, now usually employed ; and tries a short survey on the present state of air conditioning of communication means such as railway wagons, tram cars on land, and vessels on water. He, finally, enters into the explanation of the design, lay-out and the results of provisional testa of the air conditioning equipments on board the two ships above named, which are not only the pioneer ships in Japan furnished with these equipments, but also the foremost vessels in the world in which the equipments are most extensively employed, viz.all public rooms and all cabins in the quarters for all classes of passengers have been completely air conditioned throughout.
