INSTRUCTIONS FOR COMPLETION OF FORMS TO DETERMINE HOGGING AND SAGGING NUMERALS
1. Sheet 81E is the form for computing longitudinal bending stress numerals. The resulting numeral should not exceed 100.
2. The weights entered on Sheets 81B, 81C, and 81D, divided by 100 and as applicable, are entered in the “Tons/100” column of
Sheet 81E for departure and arrival conditions. Multiply the “Tons/100” by the Hogging and Sagging Factors for all weights
entered in lines 1-27 and enter totals on line 28, “Total Deadweight.”
3. Line 29 gives the light ship value for “Tons/100” and the associated hogging and sagging numerals. The light ship value
includes weights for spare tailshaft and stowage as given on Sheet 81B ([1282 + 29]/100 = 128.50). Add lines 28 and 29 to
obtain line 30 displacement and hogging and sagging numerals for departure and arrival conditions.
4. Enter the “Tons/100” deadweight from line 28 in line 31 “Numeral” columns for both hogging and sagging, and subtract from
line 30. The resulting values in line 32 must not exceed 100.
