INSTRUCTIONS REGARDING 

 THE DOCKING REPORT 



As shown in the introduction, the extent of 

 fouling is dependent on the areas in which a ship 

 has operated, the time of year when it visited 

 these areas, the total period out of dock, and 

 the percentage of days when the ship was moored. 

 Without this information, there is no way to 

 estimate the severity of the conditions to which 

 a ship has been exposed, which is the basis upon 

 which to measure the effectiveness of the paints. 



Some of these data for the docking report must 

 be obtained from the commanding officer of the 

 ship. The first page of the form (N.B . S. 223a) , 

 which has been printed to simplify the gathering 

 of this information, is reproduced on the oppo- 

 site page. The material on the reverse of this 

 form is quoted below. 



Other data required in the docking report will 

 be found in the report of the previous docking. 

 In case the ship was last docked at another yard, 

 the above form will indicate whether a report of 

 this docking is available in the ship's files. 



MOORING AREAS 



"Absolute precision in this part of the report 

 is unnecessary as the Bureau of Ships simply 

 wishes to learn whether the paint on the ship's 

 bottom has been exposed to virulent conditions 

 of fouling.

 areas, each of which is reported to have distinc-
