Coast Guard I Flashcards
What’s a vessel not under command
a vessel through some exceptional circumstance is unable to maneuver or keep out of the way
Narrow Channel vessel passes to other vessel’s port sound?
two long two short response: long short long short
Narrow Channel Vessel passes to other vessel’s starboard sound….
long long short response: long short long short
Approaching bend?
1 long blast
definition overtaking (light degrees)
when direction 22.5 degrees abaft only see stern light and no sidelighs
in head on situation how do you alter?
both to starboard (so pass port to port)
when crossing who has right of way?
vessel that has other on her starboard side needs to move **weird so if you see a boat to your port side you’re actually cool! **
the give way vessel ironically turns to starboard in order to get it lined up and be like two way traffic (crossing port to port)
difference between underway and making way and
underway= not tied up making way= moving
pecking order (knowing that narrow channel, traffic separation and overtaking takes precedence)
not under command>restricted>constrained by draft (intl)>fishing+trawling>sailing>power>seaplane
if using radar you see vessel forward you do.. if you see vessel aside you (port or starboard) COMMON SENSE
for forward: turn starboard for abeam or abaft your port: turn starboard for abeam or abaft your starboard: turn port
masthead light definition
light at fore and aft centerline, unbroken light 225 degrees, right ahead to 22.5 degrees abaft
sidelight
unbroken 112.5, right ahead to 22.5 abaft
stern light
unbroken light 135 degrees, 67.5 each side
tow light
yellow and same as stern
flashing light how many?
120 flashes a minute
for boat 50 meters, what’s light range?
masthead 6 miles sidelight 3 miles stern 3 miles towing 3 miles
for boat <50 meters but greater 12m
masthead 5 miles (if less than 20 meters, 3 miles) sidelight: 2 miles stern: 2 miles towing 2 miles
boat less than 12m
masthead 2 miles sidelight 1 mile stern: 2 miles towing: 2 miles

What is vessel RAM (6)
-engaged in laying, servicing, or picking up a navigational mark, submarine cable or pipeline; -engaged in dredging, surveying or underwater operations -engaged in replenishment or transferring persons, provisions or cargo while underway; -engaged in the launching or recovery of aircraft; -engaged in mine clearance operations; -engaged in a towing operation such as severely restricts the towing vessel and her tow in their ability to deviate from their course.
submarine?
yellow flashing light 3 seconds on and off
fishing trolling vs trawling
troll—–with line trawl—-with net (troll—-NO RIGHTS, trawl treated special)
underway vs making way
underway: free (could be dead in water) making way: actually moving
when overtaking (degree and lights)
only see stern, 22.5 degrees abaft
Using Radar and can’t see ship visualluy, how do you alter course?
