IL at the rate or ten IHileS dh AouA- Cruising boats can be had of almost any size and any price can be paid for them. When high-power boats are used. and the motor is from forty to eighty horse power, then the consunnp- tion of oil is great and the cost in- creases very rapidly. But even with the high-p0wered boats the cost of running is comparatively small.
 This season is going to be busy one for motor boat racing. The American Power Boat Association, which was formed last year. has put the sport of fair basis and by it's rules and system ot measurement a small low-powered boat has just as good a chance to win as larger or high-powered craft. These rules have been so favorably received by builders of motor boats that they have been accepted by foreign associa- tiors, and builders are now stipulating that in races that are to be arranged the American Power Boat Association rules are to govern. It has often been stated that a certain boat has made from twenty to thirty knots, or some phenomenal speed. By those who do not understand anything of what is required to make boat travel through the water at high rate of speed. these statements are taken as correct. Boats are built and run over a certain piece of water that has not been measured and after the trial a statement of the speed is given out, which is only an approxi- mate one. Later on, when the boat is put in a race and sent against other craft for a measured distance, it is found that the speed far short of what was alleged in it's first trial.
 Given the waterline length of the boat the beam, draught and the power of the motor, it is an easy thing to figure ap- proximately just what the speed of the boat should be. Take the square root l of the waterline length and multiply it ! by the power and divide this by the area of the midship section submerged. Ex- tract the cube root of this and multiply 1 it by fifteen. This will give the rating of the boat according to the Power Associations rule, and one-fourth of this will be the speed of the boat in statute miles an hour Of course, to find the area os the midship section it is necessary to measure the boat care fully but for rough estimate of this speed this area can be found by taking | three-fourths of the beam multiplied by the draught.
 1 Fast boats are being turned out from all the shops, and some of these will be very remarkable looking craft. Frank Croker has had boat built from designs by c. F. Herreshoff which is 43 feet long, 4 feet wide on the water line and is to be fitted with two 2S horse- power motors. It is expected that this boat will make 27 or 2S mile an hour, and the rule applied to this boat shows that she should do what her designer expects.
 It is probable that there will be three or four more boats like this. This boat is very lightly constructed. Her plank ing is only one-quarter of an inch thick, of mahogany, and the hull will weigh only $50 pounds. This is very light for a boat of this size, but as she is only meant for racing 1t will be strong enough. These boats cost 5000 each. Another craft that will be seen in | tllCoS WdteiS GdIly III luc SesSOls IS tilt Vingtet Un. This boat was built at Yonkers last fall from designs by Clin- ton H. Crane. She is 30 feet long and tflas 221 horse power motor. In her trials she was said to have shown re- markable speed, and so pleased are those interested in the boat with her performances that she has been entered | in the race for the Harmswortl1 cup which is to be held in England in July. Before going abroad the Vingt ct tn will be raced against a boat that is be- ling constructed specially to meet her land the race is to be for cup worth l$2, 900. The Vingt ct In weighs ITO bounds and can carry 25 gallons of oil. | These fast auto boats are not being built altogether with the idea of racing. That is their chief excuse, however, and Ieverything that will increase the speed la fraction of time is being done. The lhulls are being made as light as possi- lble and the balance of the boat is
 watched very carefully. Another use to (which they will be put is to bring some lof their owners to the city In faster time than the railroad trains will bring them, and they will have a much more pleasant trip. In other words, they will Ibe used as fast ferry boats for the ex- Iclusive use of their owners. A boat like lthat for MT. Croker will carry seven Ipersons in addition to the helmsman. IThere is a small cockpit forward where
 the steering wheel speed gear and motor lever are arranged, and in the lafterpart of this pit is a seat athwart- Iships that will accommodate two per lsons. In the centre of the boat is a pit for the motors and aft of this is another cockpit with five automobile seats. With this boat or one like it the owner Icould get downtown from anywhere 1T the vicinity of Glen Cove, Larchmont o1
 from up the Hudson River as far as
 Tarrytown in about an hour or. ever Hess.
 Fifteen miles an hour is nice speed Ito travel at on the water, and 30 or s feet is a good length to have the boat
 This gives plenty of room, and such 3
 boat could easily carry a party of ter without being at all crowded. The motor for such a boat would have to be
 of 40 horsepower and this would use live gallons of oil an hour when speeded iInstead of having the reputation seats Iaround the sides of the boat automobile Iseats are used and are so arranged thai they can be turned in any way wanted lSome yachtnen prefer to have chairs ir In. I~oo l., x>Io
