A. Type of Propulsion: (IN, O/B, I/O, etc.)
B. Number of engines
C. Type of hull (Displacement vs planning)
D. Trim tabs
E. Vessel loading
F. Operation of electronics
G. Maximum and economic speeds
A. Maximum sea conditions
B. Restricted Visibility (Need for RADAR)
C. Maximum range at various speeds
D. Fuel on Board
E. Crew Requirement (Is minimum okay?)
F. Maximum load capacity
A. Wind effects (High cabin or fly-bridge)
B. Deep draft more effected by current
C. Right or left hand propeller
D. Type of throttle and shift controls
E. Any obstructions on boat
F. What is the effect of trim tabs
Examples of “Close Quarter Maneuvers:
B. Recovery of objects
C. Maneuvering close to another boat
B.Know the limits of the boat
C.Know the limits of the crew
D.Reach crew fatigue limits quicker
A.Use no high speeds in high density areas
B.Adjust speed for conditions
C.Lack of knowledge from other boaters
D.Set the example
A.Slow in or near shoal waters
B.Refer to charts and chart plotter
C.Know your draft
D.Raise lower units on I/O and O/B
E.If in question, Stay out
F.Use the proper facility for the job
SINGLE R/H SCREW – BACKING
A.Apply full right rudder
B.Quick burst astern
C.Reduce power & steer w/rudder
D.Increase power gradually if needed
SINGLE R/H SCREW – BACKING
E.If stern swings to port give shot of forward
F.Stop and repeat if needed
G.Trim tab effect and use
TWIN SCREW – BACKING
A.Apply power evenly on both screws
B.Increase power slightly on opposite engine to turn (Increase power on port to back to starboard, or on starboard to back to port)
D.Effects of Trim tabs
O/B & I/O - BACKING
A.Steer with the helm
C.Trim Tab effect
A.Normally use helm
B.Use of twin engines
HEAVY WEATHER TURN(CAN BE HARD ON TRANSMISSION)
A.Put helm hard over (port turn)
B.Bring port engine to neutral
C.Pause then shift to reverse
D.Give short burst of speed on port engine
HEAVY WEATHER TURN
E.Bring port engine to neutral
G.Return port engine to forward
H.PRACTICE IN CALM SEAS AT LOW SPEED
A.Determine set and drift (Direction & speed)
B.Determine safe maneuvering zone
(Define zone by distance, position, &
C.Determine optimum position (Define)
D.Determine Danger Zone (define)
E.Get and keep the big picture
F.Any obstructions (rocks, anchor line, etc.)
G.Assign crew to watch obstructions and traffic in the area
H.Avoid outriggers, floating lines, etc.
CLOSE ENOUGH TO COMPLETE JOB
BUT FAR ENOUGH TO KEEP SAFE
A. Use your eye to determine distance
B. Use keys references such as your length,
width, and points on your boat.
C. Position: The angle from the object to
your boat or the reciprocal.
D. Aspect: Your relative position to the
object, Bow to, stern to, etc.
Make your vessel open and close on the object
at various angles, both leeward and to weather.
You only need to compensate for the fore and
aft drift rate and to maintain a steady heading
when the object is on the bow or stern. The
more difficult scenario is opening or closing
A.Use reasonable limits and stay within them.
B.Remember to account for the pivot point when moving the bow or stern
C.Use a combination of control and environmental forces: side force, ahead, astern thrust, rudder force, leeway, current drift
(CAUTION: Watch for anchor line and boat swinging with wind or current)
A.Know the limits of vessel and crew.
B.If in doubt, DON’T
C.Learn the motions your boat makes w/seas
D.Develop techniques to minimize your boat’s motion
E.Keep crew weight centered on small boats
F.Pitching (fore & aft) is easier on crew than rolling side to side.
G.Observe before you act. Understand your responsibilities
H. Know when to end an evolution
I. Perform as a team. Team is eyes & ears.
J. One hand for the boat and one hand for you!
over or through a crest.
K. Keep a slight bow up angle.
L. Keep the boat in the water (prop & rudder)
M. Stay calm and don’t panic.
N.Don’t go where Angels fear to tread. You do have to come back. We don’t need a second SAR case!
A.2 Facilities, 1 disabled, 1 Response
B.D/V vessel on open water drifting
C.Response makes approach crossing the “T” (with respect to prevailing forces)
position for several minutes and practices holding optimal position using opening and closing maneuvers.
E. Change coxswains and repeat above
Same as Exercise #1 except:
Response boat throws a heaving line to D/V
from optimal position. Crews of both vessels
lightly hold heaving line while coxswain holds
in optimal position. (Crew should keep the
heaving line in the water but tend away from the
