Our Boston Letter. 
Boston, Feb. 2. — Some doubt has been raised by the 
yachtsmen in this district as to the judg-ment used by 
the owner and the designer of the Boston Cup defender in 
giving her dimensions to the public. They argue that 
either Herreschoff or Watson could easily_ change their 
designs if anything dangerous were found in the Boston 
boat. It is quite true that either designer could change 
his lines, but there are few yachtsmen who believe that 
either would take the chances of ordering a complete out- 
fit of frames, plating and bracings, which a change in the 
design would make necessary. 
Then, too, it is more than reasonable to suppose that 
each of the designers has a distinct idea of his own in 
regard to what he thinks will produce the most speed in 
a 90-footer, and he would be unwilling to depart from 
those ideas, even though the plans of another designer 
looked dangerous. As a matter of fact, the dimensions 
given out by the Boston designer give but a very remote 
idea of the actual form of the boat. He has not given the 
draft of the hull, nor the draft below the rabbet, so that 
he has not told the public or the other designers just how 
far he has gone in the matter of reducing dead rise. 
The work of bending frames is going on rapidly at 
the Atlantic Works, and already more than half of the 
angle irons have been bent to shape. In the big shed the 
frame of the keel has been set up. It takes up almost the 
entire length of the shed. From bow to stern, includmg 
the outline of the keel, the lines are as nearly straight as 
it is possible to make them, and still show beauty in 
fprtn. In fact, even from these initial disclosures the 
boat shows herself to be a thorough racer. 
A delay has been caused in having the first casting of 
the -bottom of the trough keel spoiled at the Victor Metal 
Cowpmfs works, 3t t»st Brsintree. Th? mstm% 
out in such poor shape that it was thought best to run 
another one. This was done Friday night, and it is ex- 
pected that the new casting will be ready to be shipped to 
the Atlantic Works by Monday. The casting was taken 
out of the sand Saturday and will have plenty of time to 
cool. The work of cutting off the snags and smoothmg 
it up will be rushed. 
Some interesting figures in regard to the construction 
of the yacht have come to light, which seem to have come 
from reliable sources. The specifications call for 160 
pieces of bulbed steel angles, each of which is cut to the 
required leng.h for its use on the boat. Frame No. i is 
2ft. Qin. long, and the longest pair of frames are marked 
80. They are each 32ft. 6in. long. Frames numbered 
45 and 46 are each just 32ft. in length. There have been 
ordered 86 deck beams, all of which are bulbed angles. 
Six are 24ft. lin. in length, and the shortest is 2ft. 2in. 
Four U-shaped beams will be used for strengtheners at 
the mast station. 
There have been 126 plates ordered, although the plans 
call but f(V 114. The margin is for imperfect plates, or 
those which may be spoiled in the working. Row A, on 
each side of the boat, the topsides, will be of nickel 
steel, there being nine plates on each side. Row B con- 
tains 12 bronze plates, and row C the same number. Row 
D has ID. row E 8, row F S, row G 4 and H and I 3 
each. These are at the bottom of the fin. S«me of the 
plates for the fin have arrived at the Atlantic Works. 
Holes will be punched in these and afterward reamed out 
in a few days. ' 
It is with the greatest pleasure that yachtsmen who are 
devoted to the raceabout type have heard of the decision 
of the Boston Knockabout Association to offer an intercity 
cup for a series of races between them. The building and 
racing of go-footers does not come within the reach of the 
average yi^htsmen, and neither, for that matter, do the
