SCANTLINGS FOR SMAll WOODEN FISHING VESSELS

Abstract

Studies are carried out to find a suitable basis of specifying
scantlings for wooden fishing vessels for India, specially for the range
301 to 501 length overall. Equations of the type y=a + bNt (where
'y' is scantling in inches, N is cubic numeral in ftB and 'a', 'b' are
constants) are fitted to the scantling tables (applicable to vessels 50'
and above) available from U.S. A., Newfoundland, Denmark, France
and Scotland and they are found to represent the regulations accurately.
These Jines are corrected for standard frame and beam spacings
and moulded/sided dimensions to bring them on a common basis for
comparison and minimum scantling lines for the main structural
members are derived. These lines are extended to cover the range
30' to 501 which is generally outside the range of the above
regulations.
