A new design inboard hydroplane
Ninety-one and a half cubic inches—the smallest of the inboard hydroplane racing classes. The very size of the class guarantees its eventual popularity. Smaller racing classes have steadily gained in favor as improvements in engine and hull design have consistently raised the speeds in each class. The 91 cubic inch class, for which this new Flyer was designed, has several unique rules which will, aid in popularizing racing in it to a marked extent. A price limit is placed on the motor; $450, retail, is the highest price that can be affixed. Superchargers are barred. The waterline length of the hull must not be less than twelve feet; the chine beam at the widest section must be at least four feet. A total minimum weight for the hull and motor is prescribed—600 pounds. While it has been borne in mind that many persons will wish to build the 91 cubic inch Flyer not exclusively for racing, no element of speed or handling qualities has in any way been sacrificed. Yet features of this craft will make it an excellent speedy runabout for use in more sheltered waters. Such features consist partly in the double seat and provision for use of starter, following racing rule requirements. The design as shown also provides for reverse gear and hatches over the motor. These are not called for by the racing rules but the builder who wishes to leave them off should be careful that in doing so he does not lower the total weight of the outfit below 600 pounds. Total weight will, of course, vary with the motor used.
