TABLE OF CONTENTS In 1968, Captain D.R. Derrett wrote the highly acclaimed standard textbook Ship Stability for Masters and Mates . In 1999, for the Fifth edition, I revised several areas of the Fourth edition (1984) book and introduced new topics that were in keeping with examinations and developments within the shipping industry.
In 2004, the SQA/MCA made major changes to the syllabuses for the STCW 95 Chief Mate/Master Reg. 11/2 (Unlimited) Ship Stability course. Changes were also made to the STCW 95 Officer in Charge of Navigational Watch <500gt Reg. 11/3 (Near Coastal) General Ship Knowledge and Operations syllabus.
Other key changes since the Fifth (1999) edition and this Sixth edition include the following:
IMO Grain Rules and angle of list
Floodable and permissible length curves
Icing allowances effects on trim and stability
A Trim and Stability pro-forma sheet
Tabular and assigned freeboard values
Load lines and freeboard marks
Effects of side winds on stability wind levers and wind moments
The calibration book
Update of research into squat and interaction
Air draft considerations
Draft Surveys procedures and calculations
Synchronous rolling of ships and associated dangers
Parametric rolling of ships and associated dangers
Timber ship freeboard marks
Trimming moments about the aft perpendicular
Changes in lightweight and its KG over a period of time
Recent SQA/MCA examination questions.
My main aims and objectives for this Sixth edition...
