Q: What are the 4 forces affecting docking?
- Prop Wash
- Prop Wash
- Wind Answer:
- Current
Q: 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.
Q: 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.
Q: How does Current affect boat speed and orientation?
Answer: Cross current sets ENTIRE boat down current.
Q: Backing out of slip what to consider?
Answer: Wind direction
Q: 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
Q: 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
Q: 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.
Q: 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.
Q: 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 Have 2 crew handling the bow lines and forward spring line while you back into the slip, they loop this 3 lines over the outer slip piling on each side as the stern reaches the piling, and then walk the lines forward as the boat backs deeper into the slip. The bow lines are used to center the boat and the forward spring line keep the stern from hitting the dock and gets eventually fastende to midship cleat Last priority at the end fasten the 2 stern lines
No standing turn possible to help align stern with slip. Therefore everything has to be done at higher speed and the turn angle is bigger, nearly 90 degrees. Again if wind from ahead in fairway, travel past the slip before turning, turn rudder left, short kick ahead then astern etc If wind from astern you have to approach farther away from the slip and basically do a 300 degree turn...
Q: Wind blowing INTO slip: port side approach considerations?
Answer: Small oscillations can blow bow left or right while backing in. Compensate with steering/throttle.
Q: Wind blowing OUT OF slip: port side approach considerations?
Answer: That is helpful. Wind assists while backing in
Q: Heading bow into slip: considerations and preparations?
Answer:
- essential to get a line from the windward bow to the deck. Maybe have a dock person help
- bow crew relays distance to dock to helms person to not ram the dock
- in a crosswind make a WIDE turn to the WINDWARD side of the slip BEFORE entering since the bow will be blown downwind.
- with wind from ASTERN blowing into the slip boat speed will be greater. Use of spring line to the midship is essential to stop the boat
- with wind from AHEAD blowing out of the slip it will be more difficult to control the bow since slight wind shifts can make the bow fall off to one side or the other
Q: Parallel docking lines?
Answer: 1 Bow, 1 stern, 2 spring on dock side. If strong winds anchor out windwards in addition to hold boat away from dock.
Q: Parallel docking: leeward dock how to?
Q: 3 knots for mooring?
Answer: Cleat hitch, bowline, round turn with half hitches
Q: What are breast lines?
Answer: Mooring lines extending laterally out from boat like bow and stern lines.
Q: What means to belay a line?
Answer: To fasten a line to a stationary object
Q: What is the bitter end?
Answer:
Inboard end of a line
Q: What does it mean to bend a line?
Answer: Less then a full turn around a stationary object
Q: What does it mean to turn a line?
Answer: To wrap a line around a stationary object. For example one wrap completely around a pile or cleat is considered a single turn
Q: What are warps?
Answer: Lines used to move a boat within a docking area
Q: Definition spring line?
Answer:
Q: Making Way means?
Answer: A boat moving through the water
Q: Underway means
Answer: A boat adrift
Q: If you are making way ahead, right rudder will move the stern?
Answer: Move stern to left
Q: If you are dead stopped in the water, forward power and left rudder will move
boat ahead, and? Answer: Move the stern right
