Description

Merchant Ship Stability presents the theory and application of methods for maintaining ship stability. It serves as a textbook for deck officers and first year degree students.

The book discusses the methods of Simpson's rules for measuring ship form, the principle of floatation, finding the position of the center of gravity, and the effect of the center of gravity of the vessel not being on the centerline, the effect of having liquids within the vessel which are free to move and the effect of suspending weights. Topics on the assessment of stability of large angles of heel, regulations about merchant vessel stability, and dry docking and grounding are provided as well.

Deck officers and merchant marine students will find the book very useful.
