Q

Weather helm versus Lee helm

A

If you have a tiller, weather helm is when you have to pull the tiller to weather (toward the wind) in order to keep the boat going in a straight line. Lee helm is when you push the tiller to lee (downwind) in order to keep the boat going in a straight line.

Q

what is “rounding up”

A

Rounding-up is a phenomenon that occurs in sailing when the helmsman (or tiller-handler) is no longer able to control the direction of the boat and it heads up (or “rounds up”) into the wind, causing the boat to slow down, stall out, or tack.

Q

What are the responsibilities of a ‘Stand On’ vessel?

A

The ‘Stand On’ vessel is required to maintain its course and speed in order to allow the ‘Give
Way’ vessel the opportunity to alter its course and avoid a possible collision. If it becomes
apparent that the ‘Give Way’ vessel is unable or has not taken the appropriate evasive action, the
‘Stand On’ vessel must then take action to avoid a collision.

Q

You are entering a channel and see a Red and White buoy. What kind of buoy
is this and what does it mean? 21

A

Safewater or Mid-Channel Buoys indicate that there is safe water in all directions around
the buoy. They are typically used to mark the entrance to channels or the centerline of channels.
Fairway buoys, when marking the centerline of channels, should always be kept to port.

Q

What is a bifurcation buoy? What colors are associated with a bifurcation buoy?

which channel do you take if the top color is red?

which channel do you take if the top color is green?

A

Bifurcation Buoys can be found where one channel branches off into two channels or where
one channel meets another. The bifurcation buoy marks the preferred channel (typically deeper
and wider).
A red over green bifurcation buoy: the preferred channel can be taken by leaving
the bifurcation buoy to the starboard side of your boat. therefore you must take the channel to the left (port).
A green over red bifurcation buoy: the preferred channel keeps the buoy to the port side of the boat, you take the
channel to the right (starboard).

24
Q

describe shape, color and numbers (even or odd) of channel markers)

A

Aside from color, the shape, number and appearance of a buoy is very important in identifying
the type of buoy. All green lights or buoys are numbered with an odd number and all red lights or
buoys are numbered with an even number.

The shape of a buoy can be cylindrical (called a ‘can’ because of its shape), conical (cone), spar
and pillar.
Green lights or buoys will have a flat top – can, spar or top mark. Red lights or buoys will have a
pointed top – cone, spar or top mark.

25
Q

List 3 characteristics of a Port channel buoy.

A

green

26
Q

What should you do in conditions of poor visibility? 46

A

 slow down
 put on PFD’s and safety harnesses (while on deck)

 assign additional ‘lookouts’ with a ‘lookout’ posted near the bow
 instruct your ‘lookouts’ to look and listen
 record your position on the chart and update your position frequently
 turn on your running (navigation) lights
 make appropriate sound signals  attach a radar reflector
 turn on radar set for a range of 3 miles
 stay out of shipping lanes
 idle so you can hear better
 listen to channel 16 on your radio

27
Q

What sort of weather would you expect to find with cumulonimbus clouds?

A

 strong, shifty winds;
 rain;
 thunder and lightening

28
Q

There is no ‘Stand On’ vessel when two _________?

A

When power driven vessels are meeting
head on or near head on, each vessel must
alter their course to starboard. This means
that each vessel will pass the other port
side to port side. In this situation there is
no ‘stand on’ vessel, each must stay clear
of the other.

29
Q

Describe symptoms of mild hypothermia.

A

 uncontrollable shivering
 numbness in the hands and feet
 impaired judgment
 fatigue, loss of co-ordination, weakness

30
Q

What is the risk of sailing by ‘the lee’? 11

A

Accidental jibe

31
Q

Water depth is 12ft., height of bow above water is 4 ft., wind conditions are moderate
and you wish to anchor to overnight – how much anchor rode do you need?

A

 overnight anchoring in moderate conditions – you will need a 5:1 scope. (5 X 16 = 80);
 you will need 80 ft. of anchor rode

32
Q

What is the benefit of having a small section of heavy chain at the end of the anchor
rode? 48

A

 the chain prevents chafing (a nylon line attached directly to the anchor would
easily chafe on the bottom and break)
 the chain causes the anchor to lie more horizontal for a better bite
 the chain acts as a shock absorber – when the boat pulls on its rode, it has to lift
the heavy gauge chain which takes up some of the shock before the strain reaches
the anchor

33
Q
Which tack (Port or Starboard) is the preferred tack to be in a ‘hove to’ position and
why?
A

When a boat is Hove To, it is still considered to be underway according to the Colregs and
therefore, it is best to end up hove to on a starboard tack. In this position, all sailing vessels on
a port tack must give way.

34
Q

You see a vessel approaching on a collision course – what sound signal should you
make?

A

Five short horn blasts - danger

35
Q

46 You are sailing a 27 ft. boat and it is now after dusk. Using the

diagram, draw the arc for each light you will have on and specify
the color of the light. Answer #46

A

 Red Port;
 Green Starboard;
 White Stern;
 White Masthead

36
Q

You are sailing on a starboard tack. Sailboat ‘A’ is upwind from your sailboat and is
sailing downwind on a converging course with your sailboat. You are unable to
determine which tack sailboat ‘A’ is on. Are you the ‘Stand On’ or ‘Give Way’ boat?

what if it is the same situation, but you are on a port tack 14

A

You are the ‘stand on’ vessel and vessel ‘A’ is the ‘give way’ vessel. Vessel ‘A’ is either
on a starboard or port tack. Since you are on a starboard tack, vessel ‘A’ must give way
because if vessel ‘A’ is on a port tack then the rule ‘port gives way to starboard’ applies.
If vessel ‘A’ is on the same tack, then the upwind vessel (vessel ‘A’) must give way to
the leeward vessel.

STARBOARD TACK AND DOWNWIND HAVE ROW

PORT TACK AND UPWIND GIVE WAY

FOR POWER BOATS, VESSEL ON THE PORT SIDE GIVES WAY

 If you were on a port tack, the situation would be completely different and you would
‘give way’

37
Q

47 Using the same diagram, it is after dusk, you have been sailing but

now the wind has dropped so you decide to motor sail. What lights
will you have on – draw the arc(s) and specify the color.
Answer #47

A

 Red Port;
 Green Starboard;
 White Stern;
 White Masthead

38
Q

48 You reach your overnight location and drop anchor. What light(s)

will you have on – draw the arc and specify the color.
Answer #48

A

 White All-round

39
Q

How many flares and type are required for a 30 ft. sailboat?

A

A minimum of three signals are required for day use and three signals for night use. Some flares
meet both day and night use requirements.

40
Q

You have a 30 foot sailboat with a diesel motor and cooking facilities – what USCG
safety equipment are you required to have?

A

 sunscreen

42
Q

You are at the helm of a 30 ft. sailboat when you feel the keel start to touch the bottom.
What immediate course of action should you take?

A

You will need to change the course of the boat immediately because you headed into shallow
water. If you are sailing upwind, tack immediately. If you are sailing downwind, head up
immediately.

43
Q

The Aft spring line stops the boat from?

The breast lines prevent the _____ and ______ from moving outwards from the dock.

A

The Aft spring line stops the boat from moving forward when tied to a dock.

The breast lines prevent the Bow and Stern from moving outwards from the dock.

44
Q

Sails are trimmed based on: A. The Apparent Wind

B. The True Wind

A

Sails are trimmed based on apparent wind direction. (Points of sail are determined by
boat angle to the true wind.)

45
Q

LIST ALL PRECAUTIONS WHEN FUELING

A

Safe Refueling Procedures – Gasoline & Diesel
Many boat fires are caused as a result of failing to follow safe refueling procedures.
1) Secure the boat to the fuel dock.
2) Have all passengers and crew leave the boat and wait on the refueling dock.
3) Turn off the motor.
4) Electrical equipment should be turned off.
5) Do not use the stove.
6) Make sure you have a fire extinguisher readily available in the event of a fire.
7) Remove all portable gas tanks from the boat – never fill a portable gas tank while it is
on the boat.
8) Close all hatches, portholes and the companionway to prevent any gasoline or diesel
fumes from entering the cabin area.
9) Make sure that the fuel is going to be pumped into the fuel tank and not into the water
tank. On some boats the water tank filler cap and the fuel tank filler cap look similar.
10) Make sure the correct fuel is going to be pumped into your fuel tank.
11) Do not smoke and make sure that no one around you is smoking.
12) Initially ground the fuel pump nozzle against the filler pipe rim. Pump the fuel with the
fuel pump nozzle pressed against the filler pipe rim in order to keep it grounded. Static
electricity can easily ignite gasoline fumes.
13) Do not leave the fuel pump unattended while pumping fuel.
14) Do not overfill the tank. You should roughly know how much fuel your boat will take
so you should anticipate when the tank is near full.
15) Immediately wipe up any fuel spills. Spilling fuel into the water is an environmental
hazard and subject to severe penalties.
16) When you have finished refueling, replace the fuel filler cap.
17) Ventilate – this is very important. Most refueling fires occur as a result of improper
ventilation after refueling. Ventilate means opening all hatches, portholes, companion
way entrance and turning the blower on (if you have one). You should ventilate the
boat for at least five minutes before starting the engine. After 5 minutes has elapsed
‘sniff’ the boat. This means walking through the boat and checking the bilge and any
closed in areas for the smell of fuel. If you detect any odor of fuel, continue to ventilate
the boat.
18) Check the boat for any signs of a fuel leak.
19) Have your passengers and crew return to the boat when it is safe to do so.

46
Q

what are the responsibilities of the give way vessel?

A

The ‘Give Way’ vessel must take early and substantial action to keep clear of the ‘Stand On’
vessel. This means that the ‘Give Way’ vessel must make its intentions clear by making a
noticeable alteration in its course or speed. This will put the ‘Stand On’ vessel on notice that the
‘Give Way’ vessel is taking evasive action.

47
Q

Power Driven Vessels Crossing who has Row?

A

When power driven vessels are on
converging paths, so that one must pass
in front of the other, the vessel that has
the other vessel on its starboard side
must stay clear of the starboard vessel
and allow it to pass in front.

48
Q

THREE BASIC RULES FOR ROW:

STARBOARD v PORT

UPWIND v DOWNWIND

POWER VESSELS CROSSING

A

STARBOARD TACK HAS ROW

PORT TACK GIVES WAY

DOWNWIND HAS ROW*

UPWIND GIVES WAY

FOR POWER BOATS, VESSEL ON THE PORT SIDE GIVES WAY,

VESSEL ON THE STARBOARD SIDE HAS ROW

* downwind vessel on a port tack gives way

49
Q

Isolated Danger Buoys

appearance?

A

mark areas of isolated danger. Isolated danger buoys are characterized by flashing white lights (if lighted) and black, red, black (BRB) horizontal lines. The top mark on an isolated danger buoy consist of two balls or discs,
one over the other.

50
Q

sounds for a sailboat to make with the boat horn in fog or poor vizibility

powerboat?

A

Sailboats – one long blast and two short blasts no longer than two minutes apart
Power Boats – one long blast no longer than two minutes apart

51
Q

how calculate anchor rode?

A

To determine how much anchor rode you
will need, you take the height of the bow off
the surface of the water (waterline) and add
the water depth. multipy times appropriate factor
