Alarming Statistics
“…the fatality rate on fishing vessels [in Canada] between 15 and 150 tonne (classed as small fishing vessels) is 32 per 100,000 fishers per year”
NL Tragedies
•NL Statistics:• 1999 until 2008 ….32 fatalities
•Many attributed to stability issues
Introduction to Basic Stability Principles
Basic stability concepts as it applies to fishing vessels – Practical application --
Buoyancy, Gravity and GZ
Lightship Curve
Weight Creep
Improper Ballasting
Port Departure Condition
Arrival at Grounds – 75% Consumables
Catch on Deck and Towing
Gear Hooked Bottom
E – Simulator Demo Video
E – Simulator Program
• Interactive features• Multimedia - DVD and
web based • Promote awareness and
understanding• Realistic experience in
safe learning environment
E – Simulator Program
• Program in Modular format• Introduction/Orientation • Module I: Why the Vessel Floats: Basic Concepts• Module II: Vessel Behaviour: Core Concepts• Module III: Seamanship and Stability and
Stability: Operating Safely• Module IV: Keeping Stable: How Changes to the
Vessel Affect Stability• Module V: Ensuring a Stable Vessel:
Construction and Regulation• Module VI: Managing Stability: Stability Booklet
and Conditions of Load
