THE COMMODITIES IN TABLES 1.99 AND 1.100 HAVE BEEN THE TOP ITEMS SHIPPED IN THE UNITED STATES INLAND WATERWAYS AND ON THE GREAT LAKES SINCE 1970. DURING THIS TIME THE ENTIRE SHIPPING INDUSTRY HAS BEEN STABLE CONCERNING TONS SHIPPED AND TON-MILES (TABLE 1.98).

BOAT CLASSIFICATIONS WERE CHANGED IN 1976. WHEN COMPARING DATA FOR 1973 (TABLE 1.101) TO DATA FOR 1976 (TABLE 1.102), CARE MUST BE TAKEN TO COMPARE DATA FROM IDENTICAL CLASSIFICATIONS.

THE 1973 VALUES ARE NOT THE SAME AS FOUND IN EDITION 2 OF THE TEC DATA BOOK BECAUSE THE COAST GUARD RE-ANALYZED THE 1973 DATA USING 1973 BUREAU OF THE CENSUS "POPULATION ESTIMATES (REVISED)." (CENSUS POPULATION DATA FOR 1970 WAS USED FOR THE DATA IN EDITION 2.)

TO COMPARE

FOR 1973 THE NUMBER OF RECREATIONAL BOATS IN USE IN THE UNITED STATES INCREASED
FROM 8,165,000 IN 1973 TO 11,322,000 IN 1976. THE PERCENTAGE OF MOTOR
AND NONMOTOR BOATS REMAINED ALMOST THE SAME IN THIS TIME PERIOD (78.8%
WITH MOTORS IN 1973 AND 77.2% WITH MOTORS IN 1976). ONE SIGNIFICANT
CHANGE WAS WITH ROWBOATS IN WHICH 32.0% OPERATED WITH MOTORS IN 1973
AND 62.2% OPERATED WITH MOTORS IN 1976. PASSENGER-HOURS PER BOAT IN-
CREASED FROM 564 TO 674 DURING THIS PERIOD AND BOAT-HOURS PER BOAT
INCREASED FROM 189 TO 199 INDICATING MORE PERSONS PER BOATING OUTING IN
1976.

Number of Boats Used for Recreation and Length
of Exposure, 1976

1970 census data was used to estimate the number of boats in use when the Coast Guard conducted their Nationwide Boating Survey in 1973. In the 1976 edition of the Nationwide Boating Survey, the 1973 data were reevaluated using 1973 census data. Therefore the data in 1973 is revised from Edition II of the Transportation Energy Conservation Data Book.

Most 1973 and 1976 data cannot be compared because the survey changed the definitions of same types of boats. Comparisons can be made only
with identical types (rowboat, jonboat, sailboat, canoe, kayak, and houseboat).

The survey doubts the accuracy of these figures because of a misunderstanding of the question or the transfer of incorrect data.

THE CHANGE IN THE PERCENTAGE OF PLEASURE BOATS BY HORSEPOWER CATEGORIES
WAS INSIGNIFICANT FROM 1973 TO 1976. (SEE TABLE 1.103.) THERE WAS,
HOWEVER, A LARGE SHIFT FROM HEAVIER WOOD AND STEEL BOATS (20.8% IN 1973,
15% IN 1976) TO LIGHTER ALUMINUM AND FIBERGLASS BOATS (75.3% IN 1973,
81.4% IN 1976). THIS SHIFT WAS EVEN MORE DRAMATIC FROM 1970 TO 1977.
IN 1970, 31.4% OF ALL PLEASURE BOATS WERE WOOD AND STEEL, 65.5% WERE
ALUMINUM AND FIBERGLASS. BY 1977 THESE RESPECTIVE PERCENTAGES WERE 13.6
AND 83.6.*
