43
Center of gravity
Weight of boat acting vertically down
44
buoyancy
Upward force of water displaced by the hull
45
Equilibrium
buoyancy = gravity
46
Rolling
Downward force of gravity is offset by upward force of buoyancy
47
Heeling
Center of gravity is no longer in line with the center of buoyancy.
Temporary listing
48
Listing
Center of gravity not on centerline. Will heel until equilibrium is reached
49
Types of stability
Longitudinal (fore and aft prevents pitching)
Transverse (Athwartships, keeps from rolling)
50
Types of forces
Static (internal. Weight in hull)

71
Keel and 2 types
Backbone of the boat
Bar keel: vertical stiffeners protect bottom of boat but draw more water
Flat keel: I beam built into hull. Less protection but draws less.
72
Cavitation
Partial vacuum of air around prop blades
73
Free surface effect
Water that is free to move inside an compartment and can shift from side to side (ie fuel tank)
74
Free communication with the sea
Movement of water in and out of the vessel through an opening in the hull.
75
Down flooding
Introduction of water or fluid through an opening in the vessel (ie rain water with hatch open)
76
Things that effect vessel stability
```
Size and shape of hull
Draft
Trim
Displacement
Freeboard
Superstructure
```
77
Disabling casualty
Make the boat not serviceable.
Eg: engine problems/damage, fuel leak, no bilge
Uw: go to safest mooring if possible.
At station: Charlie status until fixed.
78
Restrictive discrepancy
Restrict the operations of the boat such that it can perform some missions, but not all missions safely.
Eg: engine system outside of normal range
Can operate with Operational Commander waiver.
