From the Scientific American
 The new boat has more beam and con- eiderably less dead rise than the Consti- tuition. a harder bilge and longer ends particularly in the forward overhang' Her extreme beam is 25 feet inches; her draught IS feet 9 inches, and her length over all 140 feet.
 In her midship section she shows exact ly two feet less dead rise than the Consn- tuition. and while her hull is not so shal- low as that of the Independence, 1t IS still sufficiently shallow to allow the ends to be carried out to give practically the same length on deck as the crownishield boat. While she will thus secure some thing of the same long, flat floor, she diff fers from the Independence in the fact that the fullness of her bilges, as shown in the midship section is not carried out into the forward overhang, as was done in the Boston boat. the sections from the water line at the stem to the bow being something of a compromise between the almost semi-circular sections at the wa ter-Iine of the Shamrock II. and the de- cided V-sections of the Columbia and the
 
 power in. this modification, there will be decided gain in business in seaway, es- pecally when the seas are short; and while the new boat will pound somewhat heavily under these conditions, she is not likely to take the bit in her teeth, as did the Independence, and run wild under freshening breeze or in sudden puTs. Although the draft is less than that of the Constitution, the keel IS longer and the bulb Is drawn out to finer lines. The mast relatively to the road-water line is stepped in the same po- sition as in the Constitution, and with her 100 tons of lead in the keel her harder bilges, greater beam and greater length, of water line when heeled, she will natur- ally possesses larger sail-carrying power; she will spread in the neighborhood of 15.00O square feet of canvas.
 It,is a curious fact that broadly speak ing, the English designers are working on opposite lines from those outlined above. The new Fife boat as compared With the two Shamrocks, will have deeper body, considerably more dead rise, greater full ness in the garboards and some what less overall length, the mod el thus reverting somewhat to the type of the Valkyrie II and Brit annia Hence, for the second time in the history of these cup races, the Amer ican and British ueSlgnerS nave croSSsu each other, our boat running to great beam, shoalness of body, and large wetted surface and the English craft tending to greater fitness of body, large displace- ment and a small wetted surface. S2ould both boats come up to the designers ex- peotations and prove to be successes, the out come of the races will depend, more than it has for several years past, upon the conditions of wind and weather. In light breezes and troubled water the ad- vantage should lie with Shamrock H. Also when split open,' that is running dead before the wind and spinnaker set the larger displacement and fner-lined Fife boat with her smaler-wetted sur face should prove to be the faster both in light winds and strong. On the other hand, on a triangular course where there is much reaching to be done, especially under the conditions of a strong breeze and smooth sea, Shamrock III. should be yhopelessly beaten, while in a rough sea and strong wind and under any condi- tions where reefing becomes necessary, the advantage. except in reaching. should lie with the Fife boat. Seeing, however. that moderate winds and fairly smooth seas prevail during August, it would look as though the extreme boat which Herre-
