January, 1927 M. S. WEsT HoNAKER—Main engine, McIntosh & Seymour—At left, top of engine showing valve operating mechanism—At right, view of main engine looking aft from port side forward end of engine room was. started fifteen times from one compressed air tank. As_ the equipment includes two such tanks the stored supply of air would be enough to start the engine thirty times. Other results of the trial such as oil consumption and temperatures are shown in Table 2. After the test the WEST HONAKER returned to the army supply base pier at Boston, where complete satisfac- tion at her performance was expressed by the shipping board officials. The next day, Nov. 30, the vessel left for Savannah to enter the transatlantic service. The weather on the day of the trial ‘was perfect, and many of those on board spent a large part of the time walking about on deck without their overcoats. Luncheon was served on board to guests and observers. The test was conducted with Capt. Edward B. Lambert of Machias, Me., and Capt. Joseph Kemp of the Fore river plant on the bridge. Diesel Engine is Unique The conversion of the WEST HONA- KER from steam to diesel drive and her immediate entry into regular serv- ice is an important step in the at- tempt to build up an American mer- chant marine. The WEST HONAKER’S main engine, a_ 6-cylinder, 4-cycle, single acting diesel engine of 2700- horsepower, is the largest single act- ing American marine diesel engine ever built, and is one of the largest all American diesel engines of any type. The vessel is of the conventional three island type with poop, bridge, and forecastle. Quarters for passen- gers and officers are located in the midship house as are the galley and dining’ rooms. The staterooms throughout are large, airy and com- fortable, special attention having been paid to ventilation and insulation from heat so that these rooms will give maximum comfort even under tropical conditions. The staterooms are fin- Index for 1926 The index for the year 1926 covering all of the valuable edi- torial material which appeared in MARINE REVIEW last year is now ready for distribution.

The vessel is profusely electric lighted throughout.

On the WEST HONAKER the electrical equipment .includes a 2-ton York ice machine direct driven by a Diehl motor, a Sperry-Westing- house automatic or hand controlled steering gear, eleven winches, wind- lass, radio equipment, a _ 5-gallon coffee urn, and several smaller ones, a 100-gallon water heater and several smaller ones, electric radiators, whistle, and a 1000-watt searchlight. Auxiliary Diesel Engines In addition to the main diesel en- gine, which was furnished by the McIntosh & Seymour Corp., the vessel carries several auxiliary diesel en- gines also made by this company. These include a 4-cylinder 4-cycle en- gine of 400-horsepower driving a three ‘stage air compressor and a 75-kilowatt generator, and two 2-cylinder 4-cycle diesel engines, each of 108-horsepower and each direct connected to a 75- kilowatt generator. The fuel oil for all purposes is carried in double bottom tanks in suf- ficient quantity to give a cruising radius of 20,000 miles. A small emergency lighting and compressor set has been provided. This consists of a 22-horsepower Mianus diesel engine driving a 14-kilowatt generator and a Rix-compressor. A detailed list of equipment is given in Table 3. The Shipping Board Program There is approximately $25,000,000 available for carrying out the ship- ping board’s program of conversion of vessels from steam to diesel power.
