FOREST AND STREAM. 
[March 30, 1907. 
The Hydroplane. 
On March 16 Forest and Stream published an 
article on the hydroplane boat, describing her 
peculiar model. On Saturday, the 23d, this boat 
gave another demonstration before a number of 
interested visitors. Mr. C. Andrade, Jr., gen¬ 
eral manager of the Hydroplane Co., himself 
ran the boat as the inventor, Mr. Canaux, was 
in France. 
Lacking the experience of the French inven¬ 
tor, Mr. Andrade had considerable difficulty in 
getting the engine, a single cylinder, air cooled, 
four-cycle De Dion engine of 8 horsepower, 
started. 
A piece of sash cord, wound once around a 
grooved wheel about a foot in diameter just aft 
of the cylinder, then through a small pulley to 
port and aft to the man seated in the stern, 
formed the starting apparatus. A quick yank on 
this cord started the engine; but having no 
heavy fly-wheel to carry it by the compression 
stroke, repeated attempts to start it were un¬ 
successful. Many spectators got tired and left, 
but those who stayed were well repaid by the 
sight of that little 11ft. scow fairly flying up 
and down the calm waters of the Harlem. When 
she did start after a short rest she went off 
first shot. 
A new, tbree-bladed propeller was put on for 
this trial, but as no time on a measured distance 
was taken, her speed could not be judged other 
than this. The Seabury people sent out a high 
speed mahogany launch about 30ft. long, fitted 
with a Speedway engine. This boat, they claim, 
makes 17 miles over a measured mile. The little 
hydroplane ran neck and neck with this boat 
when Mr. Andrade could get his gasolene mix¬ 
ture adjusted right. And once or twice when 
he accidentally had her adjusted perfectly she 
shot ahead of the larger boat quite fast. It 
was an excellent demonstration of the boat’s 
ability and showed great possibilities for extreme 
speeds. 
One of the greatest points of difference in 
the actions of the two boats was this. The large 
boat, of the ordinary, accepted speed boat model, 
was running up hill all the time on an angle 
of about five degrees, whereas the hydroplane 
was not over about two degrees, and in her 
spurts ran just about level. 
Jamestown Yacht Races. 
Norfolk, Va., March 25.—An event in which 
the greatest interest will center, is the yacht rac¬ 
ing at the Jamestown Ter-Centennial. Five cups 
have been offered for these races and they will 
attract the largest fleet of sailing vessels ever 
gotten together for any event in the history of 
yachting. The offer of any one of the five would 
have aroused much interest and the proffer of 
so many illustrates the magnitude of the under¬ 
taking. These cups are offered by King Edward, 
of England; Emperor Wilhelm, of Germany; 
President Roosevelt, Sir Thomas Lipton, and the 
Jamestown Exposition Company. The official 
announcement has just been received by cable¬ 
gram of the offer of a gold cup by King Edward 
and the event has been promptly scheduled. The 
King’s cup is offered for the 20ft. class, the class 
of small boats that has aroused keener interest 
than any other in the racing lists of the past 
few years. This is known as class Q. In the 
contest for this cup, Canadian yachts will take 
a hand and the Fife ship yards of Scotland and 
• the Alfred Mylne yards of England are each 
building a boat for this event and two are being 
constructed in Canada. The boats that are being 
built in Scotland and England have an interest¬ 
ing significance since it will be the first essay of 
English designers at turning out boats to the 
American rule, which will probably obtain in the 
next race for the America’s cup. 
Advices from Germany state that at least two 
boats are being built in that country for the 
Jamestown Exposition cup races, and while the 
advice does not specifically indicate which of the 
cups will be contested for, yet the intimation is 
conveyed that they will try for the King Edward 
trophy. Emperor Wilhelm’s cup will bring out 
a most interesting race. It is offered for all 
classes of schooners racing at the regular rating, 
with full time allowance in accordance with the 
standard scale. It is open to schooners of classes 
A, B, C and D, sailing as one class. President 
Roosevelt’s cup will be for competition in the 
27ft. and 30ft. classes of sloops and yawls. This 
is known as class P and is a popular class. Ger¬ 
man and Canadian boats may also enter the con¬ 
test for this cup, and in this they • will have 
strong competition from New York boats which 
are mainly of the 20ft. and 33ft. classes. The 
t 
Sir Thomas Lipton cup is offered for smaller 
boats, the 15ft. and 18ft. classes, and it is expected 
to build up a size yacht that has been little de¬ 
veloped in the last three or four years. The 
Jamestown Exposition cup is a free-for-all for 
boats under 40ft. racing length contesting with¬ 
out time allowance, to give a chance to those de¬ 
signs which do- not fit the present rule very well. 
The only class unprovided for in these special 
cup races are the big sloops, and it is likely that 
such a trophy will be offered to them to race in 
one class with full time allowances, 40ft. and 
over tO' be eligible. Besides these races will be 
offered for all classes of boats from class A 
down, for schooners, sloops, cutters and yawls, 
so that no boat going to + he exposition need fail 
of an opportunity to race. All races are to' be 
under the rules of the Atlantic Coast Conference 
and all are to be under the universal rule of 
measurement. 
Invitations have been extended to the yachts¬ 
men of every country in the world and assur¬ 
ances have been received that there will be rep¬ 
resentation of foreign clubs in keeping with the 
importance of the contests. Sir Thomas Lipton 
has shown much interest in the event and will 
visit the Exposition races, at Gravesend Bay, 
Long Island Sound, Massachusetts Bay, the New 
England coast, the Middle and South Atlantic 
coast, and the Great Lakes. 
Hampton Roads, with its tributaries, offers a 
splendid course for yacht racing, and it is 
planned that the smaller classes shall cruise over 
the inside course which includes the Chesapeake 
Bay, and the larger classes, over the outside 
course which is reached through the gateway to 
the Atlantic ocean between Cape Charles and 
Cape Henry. The Jamestown International yacht 
races will start Sept. 9 and will continue until 
the end of the month if necessary to complete. 
The president of the Jamestown Yacht Racing 
Commission is Dr. J. E. DeMund, Brooklyn, N. 
Y.; Secretary, Jame F. Duncan, Norfolk, Va. 
Rube, it is reported, could not stand the fast 
pace set at this big metropolis and is going back 
to rusticate in Maine, Mr. Geo. Granberry hav¬ 
ing sold her to Mr. Wm. J. Latta, Jr. Mr. Stan¬ 
ley M. Seaman, yacht broker, did the swapping.
