2I FOOT AUXILIARY YAWL CONSTRUCTION PLANS DESIGNED BY SMALL BROS. FOR E. A. CHADWICK, 1902. 
21-FOOT AUXILIARY KNOCKABOUT DESIGNED BY SMALL BROS. FOR E. A. CHADWICK, 1902. 
2 J -Foot Aaxiliaty Knockabout. 
The accompanying plans of a 2ift. auxiliary knock- 
about were made by Small Brothers, of Boston. The 
boat was designed for Mr. E. A. Chadwick, of Lynn, 
Mass., who will use her for afternoon sailing and 
short cruises. While the design shows no unusual fea- 
tures, the boat should be an able, comfortable little 
craft, with a fair amount of speed, and can easily be 
handled by one man. A three-horsepower motor is 
placed under the cockpit, where it is out of the -way 
and yet easy of access. The cabin house is loft. long, 
and there is 5ft. headroom under the carlins. The 
cockpit is 7ft. long and is watertight. 
The dimensions follow: 
Length — 
Over all 32ft. 3 i"- 
L. W. L 2ift. 
Overhang — 
Forward 5ft. 3 in- 
Aft 6ft. 
Breatith-- 
At deck 8ft. 6 in. 
L. W. L : 7ft. II in. 
Draft- 
Extreme 5ft. 3 in. 
To rabbet . . . . 2ft. i in. 
Freeboard- 
Forward 3ft. 
Least ift. II m. 
Aft 2ft. 4'/4in. 
Ballast outside 3,000 lbs. 
Sail area — 
Mainsail 435 sq. ft. 
Jib 92 sq. ft. 
Total 527 sq.ft. 
so often changed that many gentlemen hesitate to 
buiW and no wonder. Taxing girth at bow and stern 
discourages freeboard, and to find the beam at a point 
one-eighth aft and forward of bow and stern is rather 
a complicated job to the average yachtsman, and peo- 
ple say, "Hang the racing rules." 
All rules mean by length AT waterline, the distance 
from A to B along the line A C B (see figure). Now 
my plan is to get the length OF waterline, which 
Rating Rules. 
Editor Forest and Stream: 
The many racing rules of to-day are so complex and 
really is A D E B, and we will call it for convenience 
curved waterline and express by the letters C. W. L. 
This line is longer in scow racers than in boats with 
V sections; therefore, tax it, and so as not to discour- 
age beam, subtract one-half greatest beam at waterline. 
This gives us C. W. L. — greatest beam at W.
