40 THE DESIGN AND NEW CONSTRUCTION 



In the condition calling for actual weights of load, the coal, reserve feed water, and potable water 

 should be in accordance with actual stowage capacities, and the supplies and accounts' stores should be 

 worked up for the design period from the schedule furnished with Bureau's letter No. 409-A-175; 

 13181-A-195, of June 2, 1910. If the actual weights of the remaining stores are not available, the 

 design weights may be used. 



Sheet 12. — A note should be added on the curves of transverse metacenter and center of buoyancy, 

 indicating the reference line through which the curves are read. The reference point for curve of center 

 of gravity of water-line should be stated. The scale for curve of addition to displacement for one foot 

 change of trim by stem should read "|-inch equals one ton." 



3. Booklet of inclining experiment data, referred to, is returned under separate cover for revision in 

 accordance with the foregoing.

Instruction No. 3. S. & C. Branch, November 16, 1911. 



Method of Checking Re-Measurement of Coal Bunkers. 

 Calculations made in accordance with Weight Classification, Supplement No. i. 



Sheet I.^ — Check computations on this sheet. See if the "Additions" and "Deductions" are correctly 

 brought forward from Sheet II. The capacities of telescoping coal chutes when in stowage position and the 

 capacities of escape trunks should be included in the total capacity, but should be stated separately, in order 

 that it may be readily deducted when they are not filled. (See 1603-A-18; 3037-A; 13181-A-180, March 

 31, 1 910.) If there is a sloping protective deck, note to what line the " Deductions to bottom of beam" are 

 made. Compare with sister ships if available. 



Sheet II. — See if the items and totals look reasonable. 



Sheet III. — See if gauge marks are at the 100 or 200 cu. ft. levels and that they do not fall within 6 

 inches of each other. Check several of the distances from reference points. There should be a sheet for 

 each bunker. Note how the top gauge capacity agrees with the capacity given in Sheet I and whether the 

 tanks are included in gauge capacity. 



Sheet IV. — See if capacities in cu. ft. are correctly transferred from Sheet I and that the reductions 

 to tons at 43 cu. ft. are correct. Check the addition of column for official capacity. See if the other ton 

 items look rational. 



Note if the Constructor states, in the letter forwarding the calculation, that the Commander-in-Chief 

 and the vessel have been furnished copies. 



Check from the tracing which should be furnished the Bureau. 



If the calculation is found to be correct, date and initial and have a blue-print made of Sheet IV for 

 "Ships Information" before filing. 



If the corrections are necessary or if not in the form required, the calculation should be returned for
