Coxswain Flashcards
false alarm
14usc88 - case where subject reported to be in distress is confirmed not to be in distress and not to be in need of assistance. In false alert cases, the reporting sources either misjudged a situation or inadvertently activated a distress signal/beacon resulting in erroneous request for help, but did not deliberately act to deceive.
hoax
a case where info is conveyed with intent to deceive
class D felony-10 years prison
subject to civil penalty of not more than $5000
liable for all cost of the CG
This does not change the policy that until determined other wise the CG units shall appropriately respond with out delay to any notification of distress, even if suggested to be a false alert or hoax.
surface swimmer
normally deployed only to assist in MOB situations. THEY SHALL NOT ENTER CAPSIZED VESSELS. The coxswain will designate one of the crew a simmer, a swimmer should only be used when absolutely necessary because when a crew member goes over to assist it means additional person has to be picked up from the water. Another crew member must tend the line attached to the swimmer at all times
general salvage other than towing
CG units should only engage in salvage other than towing when limited operations can prevent a worsening situation or complete loss of a vessel. ANY salvage operations shall be performed at the discretion of the units OIC/Co
ex allowing next tide to come in to refloat, helping set anchors, evacuating passengers, helping determine seaworthiness.
CG fire fighting policy
CG primary mission is to save lives then property. The CG will only engage in fire fighting operations :
In support of fire fighting agency, under supervision of qualified fire marshal/officer. except to save the life in early stages of fire to avert significant threat with out undue risk
CG renders assistance based on level of personnel training and adequacy of equipment
CG shall be prepared for and respond to fires onboard CG vessels
SAR assistance policy
the MSAP is result of an effort by congress in 1982. It directed the commandant to review CG policies and procedures for towing and salvage disabled vessels in order to further minimize the possibility of CG competition or interference with commercial enterprise.
flare response policy
reporting sightings of red/orange flares must be treated as distress situations unless sufficient available information indicates no distress exists.
issue MARB
the sighting information shall be recorded in an appropriate log where it will be available in the event that additional information becomes available that a distress incident may have occurred in the area near the time of the sighting.
SAR agreements
are formal written documents used to resolve coordination problems, such as guidance for entering another’s AOR or providing SRUS
SAR program objectives
- minimize loss of life, injury, and property loss and damage in the maritime environment.
- Minimize crew risk during mission
- Optimize use of resources in conducting SAR
- Maintain a world leadership position in maritime SAR
definition of SAR
prevent death or injury to persons and loss or damage to property in the maritime environment.
2 SAR program goals
- prevent death/injury
2. prevent loss/damage to property
coxswains responsibilities

coxswain authority
USCG regulations 1992 5000.3
subject to articles 88-91 of UMCJ
The coxswain is a direct representative of the CO or OIC and as such has authority and responsibility which are independent of rank or seniority in relation to other personnel embarked. The coxswain authority and responsibility only exist on a specific sortie or mission.
coxswain relief

SAR legal 2 times held liable
- USCG acted in a reckless and wanton manner
2. USCG engaged in negligent conduct that WORSENED THE POSTION OF THE VICTIM.
coxswains ability to leave boat
while completing the mission is secondary to ensuring the safety of the crew and passengers and boat, the coxswain may leave the boat if:
- in the coxswains judgment and after careful consideration of the remaining crew members experience, the operational benefits clearly out weight the risk of leaving the boat without a qualified coxswain
- when time permits every effort is made by the coxswain to receive the concurrence of the CO.
commercial assistance on scene
when commercial salvers are on scene performing salvage, CG units may assist them with in the units capabilities, if the salvers request
emergency phases of SAR UNCERTAINITY
phase exist where 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(DOUBT)
emergency phases of SAR ALERT
phase exist when a craft or person is experiencing some difficultly and may need assistance, but is not in immediate danger or in need of immediate response (APPREHENSION) is usually associated with the alert phase
emergency phases of SAR DISTRESS
phase exist when grave or immanent danger requiring immediate response. (DANGER)
sector watch structure (SC) SAR Coordinator
has overall responsibility for establishing, staffing, equipping, and managing the SAR system.
Primary responsibility- have over all responsibility for establishing rescue coordination centers as necessary and for providing or arranging for SAR services with in US search and rescue regions
(DISTRICT)
sector watch structure (SMC) SAR Missions Coordinator
designated to manage each SAR mission and coordinate resources.
Primary responsibility- is designated to manage each SAR mission and to coordinate resources
(SECTOR COMMANDER) *never below sector level
sector watch structure (OSC) on scene coordinator
designated to coordinate SAR operations within a specified area
- most capable person available
- 2 or more SRU’s are on scene
sector watch structure (SRU) search and rescue units
a unit composed of trained personnel and provided with equipment suitable for the conduct of SAR operations
- trained personnel
- provided with suitable equipment
- for the expeditions of conducting SAR(crew/assets)
MARB policy 1st step
- notify the mariner that unless a specific request is made for alternate assistance, the mariner must accept either the alternative of letting the CG make a MARB, or the mariner can arrange for assistance
MARB policy 2nd step
if MARB is declined, the SMC may monitor the condition, but need to take no further action unless requested or the situation deteriorates.
* If MARBs are declined in a non-distress situation, the CG has no further obligation to monitor or respond unless boaters change their mind or the situation deteriorates. The burden lies solely on the boater
MARB policy 3rd step
if requested- solicit voluntary response of anyone who can assist- include general location- must be worded carefully(so not obliged to pay)-10 minute recommended before CG or AUX respond- SMC will determine reasonable period of time and circumstances- not exceed 1 hour. monitor response shall give CG ETA- notifies other mariners no further assistance needed. Maintain comms until requester establishes comms with responder
If declined issue anther MARB provide sailors # CG will not be underway unless situation deteriorates
refloating
CO/OIC approval
CG is capable of rendering assistance
owner request the assistance and agrees to specific effort to be made
CG personnel are not unduly hazard
*operator insistence -cg no obligation to request or demand , if decision to comply should be made, clear that operator is assuming risk, the fact that the action is undertaken at operators request and is against CG advice should be logged
Searches for bodies 3.4.7
if established by time or circumstance the person is dead the CG is not required to search for bodies, may assist other agencies such as police and military commands as along as they don’t interfere with the units primary duties
*use CG assets as support platform to use their equipment
disoriented vessel/ escorting vessel 4.5
the responsibility for safety and navigation of a vessel rest with the vessels operator not the CG. Units may pass printed info from current updated NOAA,LNM, light list, coast pilot. Info passes is prudent based on facts not opinion. The CG shall not provide course to steer, all info pass shall be logged. If there is any doubt of individuals safety, it shall be treated as SAR. I+
*Info we may pass: characteristics of lights, magnetic or true bearings between charted objects, charted range bearings, charted traffic separation scheme bearings, charted depths of water, charted hazards, radio beacon frequencies, charted buoy frequencies, LAT/LONG charted objects
D13 vessel/dingy adrift policy
will be initially treated as possible distress. A boat or aircraft will normally be dispatch to investigate and conduct an initial search area. Treat as PIW unless investigate efforts indicate to be an unlikely scenario. IT is not necessary to launch helo except when it will take more than a hour for a boat to be on scene or the investigation indicates the likelihood of a person overboard.
Case treatment- determined non distress remove vessel. attempt to locate owner by registration or HIN notify AOLE
uncorrelated distress
is a distress broadcast that does not include positon or identification info sufficient to generate a search
- treat as distress
- issue UMIB= the SMC will with the position at least an hour at 15 min intervals
- when sufficient info exists to establish search are, SMC will launch assets
- Direction finder

trackline search TSR
follows a vessels intended route
return- off set 1/2 track spacing form trackline of datum. Runs one sided down then other
parallel search PS
search legs align with major axis to cover large area. Uniform coverage is desired target. Could be anywhere in search area. Multi unit offset half track spacing
expanding square SS
Used to search small area when some doubt exist about the distress location. More coverage than VS. Use when confident datum is close limits.
All courses 90* to the right
2nd unit 45* to the right
creeping line search CS
search legs align with minor axis, uniform coverage.
EX. debris was found on one end. Higher probability the search object is at the end of the search area
sector search VS
used when location of object is well known
1st leg of search is the direction of drift. 120* turns to the right, all legs equal to the radius.
2nd pattern starts 30* to the right
multi
units 90* to the left
PIW track spacing and speed
.1 (200 yards) 6kts
3 min and 6 min rule
3 min - distance traveled in yards in 3 min given ships speed times or divide by 100
ex D=10000 yds
S=100kts
6 min- distance traveled in NM in 6 min given ship speed times or divide by 10
ex D=7NM
S-7kts
time/speed/distance
time in minutes speed in kts distance in NM 60 to ensure that time is calculated in min 60 S + T D
safe haven
considered a place that can accommodate a will except the safe mooring of the vessel and has available means of communication
relief of tow
SMC and coxswain of the assisting vessel determined that a hand-off can be carried out safely
Alternative assistance is desired and arranged by the operator of vessel being assisted
operational commander has a higher need for the CG resource or AUX.
datum
the most probable location of the search object corrected for movement over time
MAYDAY
distress call of highest priority, spoken 3 times on channel 16 or 2182kHZ. person boat or aircraft is threatened by grave imminent danger and requires immediate assistance. Don’t switch channel until enough info( pos, nature of distress, ect) Priority over all other missions.
PAN-PAN
channel 16 or 2182kHZ 3 repetitions. stations has very urgent message to transmit concerning the safety of a ship, aircraft, vehicle, or person
SECURITE
channel 16 or 2182kHZ 3 repetitions indicates messages concerning safety of navigation, or important weather warnings will be transmitted on 2670kHZ or channel 22A
types of hulls
displacement- pushes away water allowing hull to settle down in water
planning- sits on top of water
semi- combo of both
pitch
distance a propeller advances in one revolution with no slip.
slip
distance lost from pitch
side force
the way water comes off propeller after rotation creates side force which pushes vessel in opposite direction
displacement
the heavier the load the lower it sits in the water, the displacement or displacement tonnage of a ship is the ships weight
cavitation
formation of a partial vacuum around the propeller blades. Cause: propeller rotates at high speed, rapid ahead to astern, aerated water
stability
ability of a vessel to return to an upright position after being heeled over
buoyancy
upward force of water displaced by the hull. the force of buoyancy keeps the boat afloat, however, it may be overcome if to much weight is added
equilibrium
when a boat is at rest, the center of buoyancy acting upwards is below center of gravity acting downwards. it is at this point that a boat is considered to be in equilibrium. effected by movement of center gravity or center of buoyancy or by some outside forces
righting movement
the force causing the vessel to react against a roll in return to a even keel
45 RBM stability
one compartment damage stability criteria. any single compartment in the hull can be flooded and the RBM will have sufficient damage stability
25 RBS stability
fuel tank- water tight-not part of hull structure
water tight frame 3 to main transom aft of frame 9. 2 pressure tested air tight compartment are located between frame 3 and the bow, and aft engine well compartment which is welded behind main transom
capsizing
less likely to capsize in deep open water. escape check need survival equip, activate personal marker light, PFDs may be removed to escape. best swimmer 1st with line for others to follow. no line best swimmer 1st, worse swimmer then last is second best
towing hookups
Penang -used to reduce wear of towline
Bridal- both legs exert equal pull, for HWX legs long enough angles less than 30*
Skiff hook- like with snaphook that connects to trailer eyebolt
distressed vessel stability
righting moment, freeboard, listing, yawing, pitch, roll, deck fitting, sheen
gear adrift in water
decide whether to remove crew, put BCM onboard, transfer equipment if necessary
pre towing procedure and towing comms
remove all personnel from distressed boat when necessary, safe or practical. All personnel must wear PFD. Provide ETA ask about deck fittings and backing plates, deck layout. If anything changed since 1st contact. Offer line of communication. talk to marina keep peace if left overnight call in AM
inertia
tendency for a vessel at rest to stay at rest. Static force cause towed vessel to resist motion. Inertia is one property that causes resistance in towing vessels, other is moment of inertia
moment of inertia
occurs when a towed vessel resists effort to turn about a vertical axis to change heading. Unless necessary- DONT attempt to tow distressed vessel ahead and change its heading at the same time, less stress for both vessels when two forces are conquered individually
opening and closing
opening by pivoting or backing
closing by backing
momentum
anticipate how momentum will affect the towed vessels motion and apply an offsetting force early and gradually
shock loading
rapid, extreme increase in tension on the towline, which transfers through the tow rig and fittings to both vessels. Could damage fittings, part tow line, cause momentary loss of directional control by either vessel and could capsize small vessels. Puts strain on engine loads.
PREVENT- reduce speed, get boats in step, lengthen towline(catenary and more stretch) set course to lessen effect of seas, deploy drogue
frictional resistance
water molecules friction cause the layers of water close to the hull to try to drag along. This attempt to drag water alongside takes energy, As speed increase , this action becomes “turbulent”- takes additional energy and more speed requires even more power
in step
climb and descend waves together, gain and lose momentum at the same time, to get vessels in step lengthen towline rather than shorten if possible. minimizes shock loading
yaw
veers to one side then the other. cause by trim, may cause 1 or both vessels to capsize if severe. ways to reduce or minimize- change towline scope, adjust trim, decrease speed or alter course to reduce effect of wave or winds. deploy drogue, use a bridle
drogue use
used to minimize yawing, used to slow rate of movement. Prevent rapidly accelerating down a face of wave
safe towing speed
1.34 x square root of LW-10% ex 36 ft at water line 1.34x square root 36 1.34x6=8 8-10%(8)=7.2
tow watch
critical responsibility- assign crew member, vessel in tow and towline must be constantly watched.
report signs of yawing, listing, boat in step, towed boat overtaking due to sudden reduction in speed, position of towed boats crew, slack in towline/prevent fouled prop
sinking tows
cut towline, note vessels position by GPS or radar fix- recue crew,
Marking wreck- floatable object should be tied to towline so it is visible will mark sunken vessel for salvage later as well as recovery for towing equipment
helo ops
direct- lowered directly to deck
indirect- trailine
clear deck for operations, dead mans stick PPE-goggles helmet ear pro
DANGER- blue lights go to starboard (covered in brief)
anchoring
check charts for danger areas, approach into winds or current.
scope 5:1,7:1 HWX 10:1
anchor watch every 15 minutes
drop point on plotter, check swing circle ( look for other vessels on radar)
set anchor alarm
set EBL and VRM to see if drifting
