Fish Safe
Stability I: Know your center of gravity
Stability and watertight integrity are the two most important requirements of safe boating and fishing. Many capsizing tragedies are preventable. Understanding the vessel’s center of gravity and careful planning of stowage and added superstructures can reduce the risk of capsize. ...continued
Stability II: gravity vs. buoyancy centers
As we saw in the first installment in this series on stability, the center of gravity is a downward force that appears to be exerted from a single point or center. Now, let’s look at the center of buoyancy and how it relates to the center of gravity in various situations. ...continued
Stability III: Heeling and righting moments
In the last installment of this ongoing series on stability, we explored the relationship between the center of gravity and the center of buoyancy. ...continued
Stability IV: Flooding not the only cause of capsize
In the third installment of our series on stability, we discussed heeling and righting moments. One reader pointed out that in a capsize event the center of gravity (COG) would move to the side of the vessel because of a shifting load.
