There is also another difference between Professor Hovgaard's method of 

 figuring the trim and the method employed here. 



In figuring the maximum trim which will exist when either the entire forward 

 or aft part of the ship is bilged, Professor Hovgaard considers the stability moment 

 of the reduced water plane —

In calculations employed in this paper the stability moment of the original 

 water plane is considered —

 axis of the original plane —
