FOREST AND STREAM. 
report is circulating there that Sir Thomas Lipton has 
given the order to Fife to design Shamrock III. Of 
course it is safe to say that Mr. Fife has such a design in 
his mind — probably on paper, too — but beyond that there 
is no truth in the report that the order has been given. 
It will be time enough to design the boat next autumn. 
If the Cup is to be won, Mr. Fife is the man to do the 
trick, but a golden opportunity was lost last year, through 
Sir Thomas "swapping horses whilst crossing the 
stream." E. H. Hamilton. 
Twin Screw Yacht Zaida. 
This handsome steam yacht, whose arrangement plans 
we reproduce, was finished in August, 1900, and con- 
structed to the order of Mr. Alfred Shuttleworth, of 
Lincoln, England, from designs prepared by George Simp- 
son, M. I. N. A., Camden, N. J., although the arrange- 
ment of the cabins is in accordance with the original 
owner's ideas. Her contract price was $87,500, and she 
was recently sold to Lord Rosebery at a price not stated. 
The vessel is mainly interesting as being of a type which 
strikes a mean between the mammoth productions in 
yacht architecture of recent years and the smaller sized 
steam yachts just outside the pale of power launches, 
whose cruising qualities are necessarily limited to coast- 
ing. The Zaida, on the other hand, while a boat of moder- 
ate expense compared with the large ships referred to-, has 
the necessary sea-going qualities combined with bunker 
capacity to enable her to undertake trans-ocean voyages. 
She is constructed of mild steel throughout to one 
grade in excess of Lloyd's Register requirements for the 
"100 Ai" class, a ndwas specially surveyer by that classifi- 
cation society's officers while under construction. The 
principal dimensions are as follows : 
Length — 
Over all 166ft. gin. 
L.W.L. ... 136ft. 9in. 
Breadth— Moulded 22ft. 6in. 
Depth— Moulded 13ft. 9m. 
Maximum draft 10ft. 6in. 
Tonnage, B. O. M. . 341 
It will be seen by the oyer all length that the vessel has 
very long overhangs, which add considerably to the grace- 
ful appearance of the semi-elliptical stern and the clipper 
stem, terminating in a beautifully carved female figure 
with scroll trail boards executed from a design specially 
prepared by the naval architect. 
The deck houses, which are two. in number, arranged 
forward and aft of machinery spaces, are fitted as deck 
saloons, with main entrance and drawing room respective- 
ly. They are beautifully furnished and upholstered, the 
fixtures being of the highest grade. 
The arrangements below deck are much of the usual 
order, but finished in the most luxurious- manner. 
A feature of the deck houses is the continuation of the 
aft end sides and top to form deck shelters or cosy cor- 
ners, where retreat may be had in dirty weather without 
the disadvantage of going indoors. 
The ventilation is complete and ample, the old-fashioned 
gooseneck and mushrooms being superseded by Simpson's 
patent diaphragms. 
The yacht is propelled by two sets of engines of the 
usual inverted triple expansion type, having cylinders 
nin., 17m. and 26in. diameter by 2oin. stroke, steam being 
supplied by a single ended boiler 13ft. diameter, at a 
pressure of isolbs. per square inch. On trial the engines 
developed 620 I.H.P. combined, propelling the vessel at a 
mean speed of 12.8 knots. 
The auxiliary machinery comprises electric light instal- 
lation, steam steering gear, steam windlass, etc., the whole 
being supplied by a vertical donkey boiler. 
Altogether the Zaida, though relatively small in size, is 
a notable addition to the ever-increasing fleet of modern 
yachts owned on both sides of the Atlantic. 
The Rating: Rules. 
Editor Forest and Stream: 
In your issue of the 18th inst, Thalassa points out with 
reference to my notes on yacht measurement, that a cor- . 
rected length under the old Seawanhaka rule is a measure 
of speed rather than of mere size. Now, curiously 
enough, I have a private letter from a well-posted yachts- 
man, who disagrees with me in quite the opposite way. 
He contends that size — in yacht measurement — is the 
summation of the' speed-producing factors, and conse- 
quently the various forms of the length and sail area rule 
do not fairly represent size in so far as they take no 
account of certain factors of design such as it is now pro- 
posed to tax under the new Hyslop rule. No doubt a 
good case may be made out on either side, and it simply 
shows our want of precise terms for use in discussing this 
question. Every writer uses the word size, and no two 
in just the same sense. Some recognized rule or formula 
for expressing size would be very useful. 
When comparing yachts by length, the phrase "other 
things being equal," means, as I understand it, that the 
vessels are in every respect similar in their dimensions, 
and when such is the case, any one lineal measurement 
serves as an index to size. Length qualified by the square 
root of. sail area, is to my mind a reasonable extension 
and practical application of this principle to yachts which, 
while not strictly similar, are not grossly dissimilar. We 
might do worse than accept it as a conventional expres- 
sion of size, and use it as Mr. Hyslop has done, as the 
foundation or dominating factor of the measurement 
rule.. 
I should like to add that the question of restricted 
classes versus rules demanding complicated data is iargely 
one of local convenience. Yacht clubs able to obtain the 
services of expert measurers and having weighing ma- 
chines or other necessary gear, may successfully apply 
rules that would be impracticable for clubs in remote 
localities, and for such restricted classes be far better than 
a decline of racing owing to the sinister influence of freak 
designs. William Q. Phillips.
