define uncertainty
there is knowledge of a situation that may need to
be monitored, or to have more information gathered, but that does not require moving
resources.
Define Alert
when a craft or person is experiencing some difficulty and may
need assistance, but is not in immediate danger or in need of immediate response.
Define Distress
when grave or imminent danger requiring immediate
response to the distress scene threatens a craft or person
MARB
Marine Assistance Request Broadcast
Prudent Actions (non-distress):
1: wait for tide to refloat vessel
2: Helping mariner set anchor
3: Evac passangers
4: helping mariner determine seaworthiness
MEDICO
Passing medical information via radio
MEDIVAC
Evacuating persons under guidance of flight surgeon
Primary Concern of CG
To provide timely and effective assistance.
What does a vessel need to assist mariners for compensation
Commercial Operations License
If MARB and Assistance is declined
The Coast Guard has no further obligation to respond or monitor unless the boater changes their mind or the decision deteriorates.
Relief Of Tow
-SMC and CXN determine that handoff would be safe
-Alternative assistance is requested and arranged by the vessel operator
-OPCON has a higher need of the CG asset.
two types of Search patterns
Drifting and Non drifting patterns
Drifting Patterns
V/S and Expanding Square
Non-Drifting Patterns
Tracklines, Creep, Parallel.
MSAP
Maritime SAR Assistance Policy
MSAP Guidelines
CG cannot interfere with commercial providers.
Vessels NOT in Distress cannot rely on the coast guard for assistance and must be referred to Sector for a MARB.
