38 THE DESIGN AND NEW CONSTRUCTION 



S. & C. Branch, Nov. 14, 1911. 

 INSTRUCTION NO. i. 



Procedure for Checking Inclining Experiments. 



I. Go through entire experiment roughly. 

 Has it the required conditions, 



displacement sheet, 



cross curve sheet, 



statical stability sheet? 

 3. In case of new ships compare light conditions with similar condition worked up from returned weights. 



3. Latest inclining experiment of sister ship. 



Compare G. Ms., trims, displacements with. 

 Compare with previous experiment for ship. 



4. Go carefully through experiment data item by item. 



Sheet No. i — Check general dimensions with Chief's report or booklet. 

 In new ships check designed data. 

 Note position of base line for draught marks. 

 Sheet No. 2 — Look into question of free water. 

 Density of water. 

 Is trim excessive? 

 Sheet No. 3 — Method of handling weights. 



Check through one complete operation and compare with others. 

 Sheet No. 5 — General location and amounts of weights. 

 Water in boilers, coal and feed water. 

 Are inclining weights included in weights to deduct? 

 Sheet No. 6 — Check carefully, item by item, through Condition II, using Bureau's displacement. 

 Special attention should be paid to longitudinal C. B. Condition I. In case 

 trim of Condition I is excessive special calculations should be made for longi- 

 tudinal C. B. 

 Sheets No. 7 and 1 1 — If Condition II has been found to be correct, compare weights and locations 

 of same with designed figures on file in Bureau; also see if variations in trim 

 and G. M. appear logical. If Condition II be incorrect, check only weights 

 and locations. 

 Sheet No. 12. — See if results are rational. 

 Sheet No. 13— Check with Bureau's displacement sheet one spot on every curve. 



Is reference line for longitudinal C. B. located relative to midship frame? 

 Examine location of base line. 

 Sheets 13 and 14 — Compare with those on file at Bureau for this ship. 

 Compare with those on file at Bm-eau for sister ship. 



Conditions Rbquired: 



I — EKporimental condition. 

 II — I.ight condition. 



Ill and IV — Designed normal and full load. (This primarily for new ships for comparative purposes.) 

 V and VI — Same as III and IV, except actual instead of designed loads. 



VII — A possible condition of loading tending to materially decrease the metacentric height from that 

 in normal condition. 



(This condition may be omitted for ships without upper bunkers). 



Sheet giving effects on metacentric height for loads on various decks under varying conditions of load. 



VIII — Damaged stability condition.
