Over in the Quaker State, the Philadelphia
M. Y. C. is determined not to lose its many
sailing events in spite of all the handicaps the city and state or park officials might put in its path. This coming Fall the members will sail at “Hunting Park,’ located at the junction of Roosevelt Blvd. and Broad St. This is a new lake, evidently, and it runs due north and south with a measurement of 200x630 ft... . and
there is plenty of depth for A boats and a fine wall around it so wading will not be necessary.

Prior to the advent of the new X class there
existed in this country but two major classes, the A class and the M class. Many model yachtsmen objected to the A class because of its too complicated rule and excessive weight and size. With the advent of the Marblehead 50-800 or M class, it appeared that at last a rule had been perfected which because of its extreme
simplicity and the moderate size produced would suit everyone, and so it did apparently, because hundreds have been built and the M has formed the largest class and proved to be the backbone
of model yachting throughout the nation.

Model sailing yachts, especially racing craft, have their sailing qualities materially altered when a change is made in the amount of the rake of the mast—the center of effort of the sail plan is shifted backward when the rake is increased,
causing the boat to luff into the wind, and forward when the rake is lessened, reducing the “pointing” ability of the yacht.

All too frequently one sees a model racing
yacht skipper lining up his craft’s rudder
at the pondside, or hears him bitterly complaining of a race lost because his quadrant has loosened on the rudder post and he was unable to make a solid adjustment. Rudder assemblies
are a real problem, as even the best available books on the subject of model yacht construction slight this particular feature, or pass it over entirely.
It can be appreciated that the writer had the

In line with good practice, the hull, in the
white, should be basically free of defects and present the smoothest possible surface for the finisher.

Projects which offer boys and girls a chance to build and sail boats under supervision are limited to cities where natural facilities make them feasible and where already existing clubs and sailing activities have created interest.
