Flashcards in Coast Guard VI Boat Handling Deck (23):
1

Where does rudder turn boat?

if rudder port, will turn bow port (BUT tiller is opposite!)

2

bank cushion? bank suction?

-moving forward narrow canal, bow creates wedge, moves bow away -suction from engine causes to move stern towards edge in sum this may jerk boat to other side suddenly (especially with steep bank)

3

bow cushion? stern suction?

think two boats meeting (like bank shit) -as you start passing bow cushion pushes bow away (good), but then stern suction sucks in so gotta correct -*slow down*!

4

where is current strongest in a bend?

outside of the bend! and where it's steepest bank

5

squat? rough speed for 1 knot

increase engine speed in shallow water, engine lowers even more, may be bad....hit ground! 1 knot: 100 feet a minute

6

most important first docking line coming alongside

bow after spring line

7

tips for backing slip

have rudder slightly opposite the prop walk (to offset the walk) before you turn make sure you got enough room to swing stern or bow!

8

pitch vs roll vs heave

pitch is up and down motion bow/stern roll: side to side heave: vertical motion of entire boat

9

advance vs transfer

when turning, advance distance you move where you want, transfer is lateral movement

10

what is leeway

lateral movement downwind of your intended course

11

COB Williamson vs Anderson

Williamson: dark/fog, go 60 degrees then reciprocal...allows you to retrace your step Anderson: need multihull basically quickstop

12

With Range Towers 1) Both under 2) Top is to left 3) Top is to the right

-middle of channel -you're to the left of the channel -you're to the right of the channel

more light

equal light/dark

combo

-all else

group flash

16

what is period?

mooring buoy?

length between cycles 

white with blue band

Travel/Cruising Guide

meridien vs parallel

confusing but large scale= small areas, small scale=large areas!

Coast Pilot (international: Sailing Directions)

meridien=longitude

parallel=latitude 

1:2500 is large scale (for small area)

1:600,000 is small scale (for huge area) 

20

Rough guide: 40 foot boat, weight of anchor?

Anatomy of an anchor (4 parts) 

18 pounds

Accuracy GPS

DGPS

Radar Min/Max range

20 meters

1-5 meters!

RADAR min: 20-50 yards, max: line of sight (so below horizon screwed)

23

Importance of transducer and depth meter

3 surfaces on bottom and correlated image

need to know where it is and account for it! also, add draft of boat to get actual depth

sharp=clear, fuzzy=muddy, jagged= rocky
