Vessel handling Flashcards
How many vessels are in a group for beaching operations
6-8 vessels
A vessel can often be turned in BLANK its length by kicking the stern
Twice
What is propeller pitch
The amount of time and distance traveled for one full roatation of the propeller
What is one of the fundamental principles of vessel handling
Using sudden thrusts of power to kick (move) the stern
What factor determines the amount of craft in a wave
landing plan
What craft are stationed on the port and starboard flanks
and in the rear
Control craft
Salvage and maintenance craft
When leaving the rendezvous point what formation do the vessels form
After leaving transport area
Into a column first
Wedge odd numbers starboard, even to port
What formation is formed when leaving LOD (line of departure)
What is the distance between boats
Abreast
50 Yards
What are the four different types of formations
Closed V
Open V
Line abreast
Straight column
What are the distances for the open v formation
each craft is 50 yards astern and 100 yards abeam of the craft ahead
When do you use a straight colum
leaving the beach,
when in a rendezvous area,
or when operating in a noncombat situation
What is advance and transfer
distance gained in direction of original course once turned 90 degrees
What is tactical diameter
Distance gained right or left once turned 180 degrees
Where is the pivot point commonly
If a ships is going ahead, about 1/3 going aft from bow
How are engine orders given
- Engine
- Direction
- Speed
How are rudder directions given
- Direction
- Rudder Angle
How do you use bank cushion to your advantage
Steer slightly toward the bank and effect will keep you in deepest part of channel
What does bank suction do
Do to effect of the screws will suck stern into the bank
What is casting
without making way forward or back, turn around.
Forward on one back on other manipluate rudder to move stern
most effective way for a ship to back
Both engines back
If experiecing high winds in a narrow channel what should you do
steer into wind
Left wind steer right
Right wind steer left
5 steps to ships handling
Learn the vessel
Learn the environment
Learn if assistance is available
Learn communications
Know the task (job)
How does a deeply laiden vessel respond to rudder commands
Slowly
What gives shiphandlers the most trouble
Commands and orders
