DOCKING CLINIC ASA QUESTIONS WITH PASSED ANSWERS!!
What are the 4 forces affecting docking? - (answer)1. Prop Wash
2. Prop Wash
3. Wind
4. Current
How does Prop Walk affect boat speed and orientation? - (answer)In reverse gear Prop Walk moves the
stern to the LEFT (for right handed propeller). More speed reverse, more the stern turns left.
How does Wind affect boat speed and orientation? - (answer)In a cross wind the bow turns downwind
faster then the stern. Cross wind blows bow downwind.
How does Current affect boat speed and orientation? - (answer)Cross current sets ENTIRE boat down
current.
Backing out of slip what to consider? - (answer)Wind direction
Considerations and Procedure Backing out of slip with wind from ahead and cross? (Blowing straight out
of slip or cross wind) - (answer)- Consider that wind threatens to blow bow into piling as you turn while
backing out
- Use a doubled over midship spring line on the lee side to turn/pivot the boat while backing out
- or alternatively use a doubled-over bow line windwards to control the bow
Consideration and Procedure Backing out of slip with wind from astern and cross? (Wind blows into the
slip) - (answer)- This is called turning to windward: consider that cross wind blowing into the fairway or
wind blow into the slip may may prevent boat while turning to clear the end piling
- back away as far as possible before going into forward gear
Heading bow first out of a slip with wind from across - wind blowing against intended exit direction-
heading out with opposing wind? - (answer)Consider: Turning into fairway will be harder. Wind pushes
bow against opposite docks.
, DOCKING CLINIC ASA QUESTIONS WITH PASSED ANSWERS!!
Use a midship spring line windward to help turn the boat sooner (pivot) to avoid striking the slips across
the fairway.
Parallel undocking when easy and when harder? - (answer)Windward dock easy, lee dock hard. Also,
boats in front or aft can make it harder.
Parallel docking departure with wind blowing away from the dock - procedure? - (answer)Release lines
and let wind blow you away from dock while gently engage and disengage engine
Parallel docking departure from lee, wind blowing onto the dock-procedure? - (answer)- Stern out
preferable over bow out
- Springing stern off dock by turning rudder slightly towards dock (prop wash helps) and power stern
away while using doubled over spring line at the bow and a handheld fender at the bow
- Springing bow off dock by powering (forward) away from the dock in reverse gear while doubled over
spring line at the stern pivots boat. Use a manual fender stern to protect boat. Rudder is ineffective
here. When boat turned away from dock, then turn rudder away from dock and power forward.
Backing into slip-Port side approach- What is easier? - (answer)It is easier to approach the slip to your
left, port side approach since you can do right side standing turn to the right to align stern with slip.
Backing into slip-Port side approach, no wind: what to prep? - (answer)2 bow lines, 1 forward spring
line, 2 stern lines
Tie bow line loops on shore ends on all of them
Bitter ends cleated to cleats stern and bow end. Loops under lifeline and above back into boat ready to
go bow lines and spring line loosely coiled with loop on top.
Fenders tied to stanchions
Approach port side to dock (escape possible with right standing turn around)
Slow speed. Come to a complete stop when 90 degree before slip, before short kick with right rudder
making the boat turn approx 45 degrees to the slip, then short kick reverse to slow forward
momentum(dont't change rudder) then slow reverse to line up stern with slip entrance
