Coxswain Flashcards
Rule 1
Application
Rule 2
Responsibility
Nothing in these rules shall exonerate any vessel from the consequences of any neglect to comply with these rules
Rule 3
General definitions
Rule 4
Application (any condition of visibility)
Rule 5
Look out
Every vessel shall at all times maintain a proper lookout
Rule 6
Safe speed
Every vessel shall at all times proceed at a safe speed so that she can take a proper and effective action to avoid collision and be stopped within a distance appropriate to the prevailing circumstances and conditions
Rule 7
Risk of collision
Every vessel shall use all available means to determine if risk of collision exist. If there is any doubt then risk of collision is deemed to exist. Proper use of radar shall be used including long range scanning. Such risk shall be deemed to exist if the compass bearing of an approaching vessel does not change.
Rule 8
Action to avoid collision
Any action taken to avoid collision shall be taken, be positive and made in ample time and with due regard to good seamanship. Altercation of course shall be large enough to be readily apparent to another vessel.
Rule 9
Narrow channels
A vessel of less than 20 meters in length or a sailing vessel shall not impede the passage of a vessel which can safely navigate only within a narrow channel or fairway.
Rule 10
Traffic separation
Vessel using a traffic separation scheme shall: proceed in the proper traffic lane, keep clear of a traffic separation line, at as small an angle to the general direction of traffic, a vessel shall so far as practicable avoid crossing traffic lanes but cross at a right angle if so.
Rule 11
Application- in sight of one another
Rule 12
Sailing vessels
Rule 13
Overtaking- any vessel overtaking any other shall keep out of the way of the vessel being overtaken
A vessel shall be deemed overtaking when 22.5 degrees abaft her beam.
Rule 14
Head on situation- two power driven vessels are in sight and are on a reciprocal course or nearly reciprocal courses to involve risk of collision shall alter her course
Rule 15
Crossing situation- two power driven vessels are crossing so as to involve risk of collision, the vessel which has the other to her own starboard side shall keep out of the way and avoid crossing ahead.
Rule 16
Action by the giveaway vessel shall take early and substantial action to keep well clear.
Rule 17
Action by the stand on vessel- shall keep her course and speed. May take action to avoid collision as soon as it becomes apparent to her that the vessel is not taking appropriate action. Collision cannot be avoided by the give way vessel alone she shall take such actions as will best aid to avoid collision.
Rule 18
Responsibilities between vessels- pecking order
Non rates can fool senior people sometimes wow

14 USC 102
Primary duties
The primary document that regulates CG responsibility to maintain SAR
The coast guard shall develop, establish, maintain and operate SAR facilities.
SAR program
USCG shall develop, establish, maintain, and operate SAR facilities and may render aid to distressed persons and protect and save property on and under the high seas and waters subject to the jurisdiction of the United States. Contained in title 14 sections 2, 88 and 141 of the US code
SAR agreements
Search and rescue agreements are formal written documents used to resolve coordination problems (for example: guidance for entering another AOR or providing SRU’s to assist another agency or country)
Distress beacons
Operates on 406 MHZ. Reports of audible and visual beacons should be treated the same as a report of an orange or red flare.
Flare response policy
Red and orange flares are recognized as marine and aviation signals. Reports of red and orange flares shall be treated as a distress situation. On going red and orange flare sightings require a first light search
False alarm
When someone or something reported to be in distress is confirmed not to be and is not in need of assistance. The reporting source misjudged the situation or accidentally activated a distress beacon.
Hoax
A case where information is reported with the intent to deceive
MSAP
The MSAP is the result of an effort enacted by Congress in 1982. It directed the Commandant to “review Coast Guard policies and procedures for towing and salvage of disabled vessels in order to further minimize the possibility of Coast Guard competition or interference with commercial enterprise.
General salvage other than towing
When no commercial salvage facilities are on scene units should only engage in salvage other than towing when limited salvage ops can prevent a worsening situation or complete loss of the vessel. Examples: ungrounding small rec boats, dewatering, general damage control. Salvage ops are performed at the discretion of the unit OIC
Firefighting policy
CG will only engage in fire operations when
- supporting a regular firefighting agency
- under supervision of a qualified fire officer
- to save a life or in the early stages of fire tho avert significant threat without undue risk
Trapped in capsized vessel
Keep in contact with the people, stabilize the hull, estimate the amount of air remaining, swimmers may attempt rescue but shall not dive under or enter the vessel, may consider rerighting the vessel
STAAR
Spread out
Transfer
Avoid
Accept
Reduce
Track line search
Follows a vessels intended route.
Parallel search
Used when the search area is large and there is equal probability of the target being anywhere in the search area
Expanding square
Used when the last known position of a search object has a high degree of accuracy, the search area is small, and a concentrated search is desired
Creeping line search
Used when the estimated location of the search object has been determined to be more likely at one end of the search than the other
Sector search VS
Used when location of object is well known
1st leg is in direction of drift. 120 degrees to the right
PIW track spacing and speed
.1 NM (200 yds) 6 kts
Safe haven
A place that can accommodate and will accept the safe mooring of a vessel and has available means of communication
Relief of tow
SMC and coxswain determine that a hand off can be carried out safely
Alternative assistance is desired and arranged by the vessel being assisted
Operational commander has higher need for CG resource
Datum
The most probable location of the search object corrected for movement over time
PAN-PAN
Urgent message concerning the safety of a ship, aircraft, vehicle or person
Securite
Messages concerning safety of navigation or important weather warnings
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
Cavitation
Formation of a partial vacuum around the propeller blades. Cause: prop rotates at high speed, rapid ahead to rapid astern, aerated water
Stability
Ability of a vessel to return to an upright position after being heeled over
Equilibrium
When a boat is at rest, the center of buoyancy acting upwards is below center of gravity acting downwards.
Righting moment
The force causing the vessel to react against a roll in return to an even keel
Safe towing speed formula
1.34 x square root of LW - 10%
29 cruising speed
25 kts at 3250 rpm
Bilge pumps
2000 GPH (33 GPM)
2 bilge pumps- aft bilge pump located port and stbd of keel near transom.
Discharge 1 1/8 thru hull fitting
Sump pump 800 GPH
Disabling casualties
Casualties that make boat unserviceable.
Restrictive casualties
Boat can perform some missions but not all
Warranted risk
Balance gains with risk operation, damage to or sacrifice boat is acceptable when defending the USA, it’s citizens and or instillations, probability of saving human life warrants maximum effort when no suitable alternative exists and has reasonable chance of success risk of damage or abuse is acceptable.
Saving a human life warrants damaging our boat.
