Daily License Questions about Ship Stability and Trim: I just think people need to have some knowledge in their heads, professional or otherwise. After 2007 our world has changed due to the advent of Smart Phones. Retaining knowledge is like being able to play a musical instrument, if you do not use it you will lose it! The questions I post with will hopefully help you keep what you already know or remind you of what you should know. William E. George
Bodily sinkage = w / TPI
ReplyDeleteBodily sinkage = 1360tons / (152tons/inches)
Bodily sinkage = 8,947 inches ≅ 9 inches
New mean draft = 29'-07'' + 00'-09''
New mean draft = 30'-04''
C. is the best answer
