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.
