FOREST AND STREAM. 
[FEB. 17, 1906. 


The average for the New York Y. C. series is 
73 per cent., while that for the L. I. S. series 
is 119 per cent., and the average for all 1s 95 per 
cent. of the full time allowance, indicating that 
the allowance under the present 70 per cent. 
tables is too small. 
The large difference between the New York 
Y. C. series and the L. I. S. series is very notice- 
able. In explanation of this attention is called 
to the Indian Harbor curve (Sept. 21). The co- 
efficient of this curve, as tabulated, is 112 per 
cent., while the coefficient for its upper part is 
134 per cent., and for its lower part 97 per cent. 
Taking the 70’s and the New York Y. C. 30’s in- 
dependent of the curve it would be 90 per cent. 
These figures, taken in conjunction with the fact 
that while the New York Y. C. 30-footers are the 
top points in the New York Y. C. series they are 
frequently the bottom points in ihe Long Island 
Sound series, show that no coefficient based on 
the present method of calculating time allowance 
can be fair to all classes. The Long Island Sound 
series would be much more valuable had there 
been more boats of classes from H to N, and the 
New York Y. C. curves would have been better 
for the presence of boats of classes P, O and R. 
There were but four occasions when all boats 
sailed as one class. These were the New York 
Y. C. races of June 15, Aug. 11, 12 and 14. On 
two of these days (Aug. II and 12) there was a 
fair wind and tide and the races were finished in 
remarkably quick time with the order of finish 
on corrected time almost directly as the rating 
measurement with the small boats first, showing 
that the large boats had to give a great deal too 
much allowance for these conditions. 
Of the others, one (that of June 15) was a tri- 
angular course when the order of finish on cor- 
rected time was directly as the rating measure- 
ment with the large boat first; and the other 
(Aug. 14) was a dead beat to windward, with the 
boats well mixed on corrected time, and while 
there was a difference of over an hour on cor- 
rected time in the finishes there was a difference 
of almost 50m. in the finishes of the one-design 
class of 30-footers.

As these two conditions are more nearly those 
that the time allowance table was designed to 
cover it will be well to consider them. The ag- 
gregate corrected time for the first four boats 
for these two races was:

This shows a remarkably close finish for a 
total distance of 5914 miles. Noting and allowing 
for the fact that there was a favorable tide in 
the straight course race, which would unduly aid 
the small boat, we arrive at the conclusion that 
the time allowance, as given in the 7o per cent. 
tables, is insufficient, which also agrees with the 
average ratios derived from the curves. 
The 70s and 30's were raced persistently 
throughout the season and although they are 
boats of dissimilar form and some of the races 
were sailed over similar but not the same courses, 
still the table below, showing their performances 
on all days when both classes were represented, 
is of interest:

ness of the percentage indicated by the curve 
ratios. 
Ideally, time allowance for any one race should 
be based on the speed of the fastest boat and on 
the shortest actual distance sailed. In practice 
this is impossible, as neither of the quantities is 
measurable, and if they were, a lengthy calcula- 
tion would be needed for each race. It is obvious 
that no rule can be formulated which will cover 
boats of all sizes for all sailing conditions. The 
remedy is to avoid racing all boats as one class, 
and your committee desires especially to empha- 
size this point. 
In conclusion your committee respectfully 
recommends for adoption that the 80 per cent. 
tables in force in the New York Y. C. and East- 
ern Y. C. in 1904 be re-established.
