SECOND SESSION. 
THuRSDAY AFTERNOON, NOVEMBER 16, 1916. 
President Taylor called the meeting to order at 1.50 p.m. 
THE PRESIDENT :—We will resume the sittings of the day, gentlemen, by the reading of 
paper No. 6, entitled “Description and Trials of the Turbine Steam Yacht Winchester,’’ 
by Mr. E. A. Stevens, Jr., Member. Mr. Stevens, unfortunately, is on the Pacific coast, but 
Secretary Cox will try to give you a brief résumé of the paper. 
THE SECRETARY :—It is much to be regretted that the author of this paper is not here to 
present it in person, as he has taken a great deal of pains in assembling the information. 
Unfortunately he was called to the Pacific coast before the paper was really completed and 
was, therefore, unable to insert in the paper his analysis of the trial results, with particular 
reference to the propeller performance, as analyzed by Captain Dyson’s method. 
The author has promised to supply this additional information so that it may be incor- 
porated in the paper when it is finally printed and bound in the Transactions of the So- 
ciety. 
As the author has pointed out, the Winchester is the fourth vessel of the same name 
built for the same owner. It is, however, very different from the preceding yachts of the 
same name, in that, although she has extreme speed, the cruising accommodations and sea- 
going characteristics have not been neglected. 
At first sight an inspection of the plans would indicate that a large amount of space was 
given to the machinery, and that the owner’s accommodations were relatively small. Upon 
comparing the general arrangement, however, with the plans of other so-called fast yachts, 
it will be seen that Mr. Rouss in this vessel has unusually good accommodations for a vessel 
of this type. In the average high-speed yacht, the owner in establishing the dimensions has 
insisted upon a certain speed and has accepted such accommodations as could be arranged. 
Mr. Rouss, however, had a definite amount of accommodation that he wished to secure; he 
stipulated the speed that he would expect, and left the dimensions of the yacht to the de- 
signers, thus allowing them to produce a boat having the comfort that was required, and 
in other respects producing a satisfactory proposition from an engineering point of view. 
An examination of the table showing the relative dimensions and characteristics of the 
four Winchesters indicates that the owner’s ideas as to size and speed have been continually 
increasing. It may be said, however, that in the present Winchester Mr. Rouss seems to 
feel that he has gone as far as is necessary in either direction. 
The secretary then abstracted the paper.
