To Race Around Long Island. 
The Atlantic Y. C. and the New Rochelle Y. 
C. have arranged a race for small boats around 
Long Island. This race will be started on July 
12 from off the Atlantic Y. C. house at Sea 
Gate and end off the New Rochelle house. The 
distance is about 200 miles and more than half 
is over an open course. The conditions have 
not yet been framed, but the yachts are to be 
limited to those 50 feet over all and under. This 
course is a very good one for small boat sail¬ 
ing, and as the prizes are well worth winning 
there should be a good number of starters. 
New 38-Rater Yacht to Race. 
A NEW yacht for the 38 rating class is being 
built at Jacobs’ yard, at City Island, for a well- 
known yachtsman from designs by Henry J. 
Gielow. This yacht will specially meet the 
Dorello, the crack yacht of the class which hails 
from Marblehead, and that there will be two 
yachts in this class will please yachtsmen gen¬ 
erally, as the 38-foot class has been well thought 
of by those who want a yacht fast enough for 
racing and large enough for cruising without 
having a yacht for the larger, classes. Mr. Gie¬ 
low designed Effort and that is sufficient guar¬ 
antee that the new yacht will be a fast one. At 
present the owner wishes to be unknown. 
Gas Producer Plant for Yacht. 
A MOTOR boat, named Marenging, has been 
built for H. L. Aldrich, which has been fitted 
with a gas producer plant. In this respect she 
is unique, and this type of power plant has been 
fitted solely for experimental purposes, in order 
to determine the feasibility of using producer 
gas for marine work. The survey yacht 
Carnegie is to be equipped with a iso-horse- 
power gas producer plant, and the tests of these 
two boats will be watched with much interest. 
Marenging was designed and built by the 
Truscott Boat Manufacturing Company, and her 
principal dimensions are 40 feet over all, 38 feet 
6 inches on the waterline, 9 feet beam, 2 feet 6 
inches mean draft, 2 feet Q inches freeboard at 
lowest point of shear. The hull is well con¬ 
structed, the frames being of oak and the plank¬ 
ing of clear, red cypress. The forward part of 
the boat is taken up entirely by the main cabin, 
which is a compromise between the old style 
full glass cabin and the newer type of hunting 
or turtle-back cabin. The trunk of the cabin is 
composed of heavy plate glass sashes, which 
can be dropped down for ventilating purposes. 
Aft of the main cabin are the engine room, 
galley and toilet. The engine room and galley 
are 9 feet long, and the toilet 5 feet long. Aft 
of the engine room is the cockpit, which is 8 
feet 6 inches long. The top of the cabin is 
sufficiently strong to support any reasonable 
weight. 
Power is furnished by a 35-horsepower pro¬ 
ducer gas plant, consisting of a single-suction 
gas generator and a Truscott four-cylinder, 
four-cycle engine. The gas for the operation 
of the engine is generated in a single-generator 
suction gas producer. The producer is 24 inches 
in diameter and 4 feet high. The shell is made 
of tank steel, and is lined with a special grade 
of firebrick lining, at the bottom of which is at¬ 
tached a shaking grate, available through a 
cleaning and ash-pit door for the inspection of 
the fire and the removal of ashes. The fuel is 
charged into the producer through an automatic 
vestibuled charging hopper, so arranged as to 
preclude the possibility of admission of air to 
the upper zone of the producer. The hot gas 
is taken off at the top of the producer through 
a special three-way valve having one common 
connection with the producer, arranged on one 
side with a purge stack, and on the other side 
with a connection leading to the Monel metal 
gas scrubber, which is located on the deck house 
over the engine room. This scrubber is 12 
inches in diameter and 6 feet long, weighing 
60 pounds. In the scrubber the "'as is passed 
through numerous sprays of water, which cool 
it and cleanse it of all dirt and soot, and prepare 
it for its proper use in the engine. The gas 
leaves the scrubber at the after end through a 
lower connection, and passes directly to a gas 
and air-mixing valve which is substituted for the 
ordinary carburetor. This valve is arranged 
for the proper control of the mixture of gas and 
air, and also acts as a throttle in order to give 
the desired speed to the engine. 
The operation of the plant is, briefly, as fol¬ 
lows : A fire is kindled on the grate, and coal 
is charged into the top of the producer until 
the fire is of a proper depth for correct gas 
making.^ Vyiien hurried starting is desired, a 
fan, which is located in the locker on the star¬ 
board side of the boat, is operated by hand. 
The air leaving this fan enters the producer 
underneath the grate, passes up through the 
fire, and the products escape through the purge 
pipe_ until the fuel is heated to the proper gas¬ 
making temperature, when the purge valve is 
closed and communication made with the gas 
scrubber. A small vent pipe near the engine 
is then opened to the atmosphere, and the fan 
turned until gas appears at this vent. This fan 
is only used in starting the producer, and as 
soon as the engine is under way, the opera¬ 
tion of the fan ceases. 
The proper adjustment of gas and air is then 
made at the gas-mixing valve, the spark re-
