PSP#2 Flashcards
Which vessels do the navigation safety regulations apply to?
Self Propelled vessels of 1600 or more gross tons and towing vessels of 12 meters or more when operation in navigable waters of the U.S. (With some exceptions)
What exemptions are there for warships or government vessels of 1600 or more gross tons?
Warships or government vessels equipped with approved electronic navigation systems do not have to comply with the chart, position fixing or ais requirements of this part.
What exemptions are there for foreign vessels of more than 1600 or more gross tons?
Except for the requirements for ARPA, AIS and tanker steering gear, this part does not apply to foreign vessels.
Not destined for or departing from a port in the U.S if in innocent passage through territorial sea; or transit through the US waters that form part of an international straight.
What exemptions are there for towing vessels of 12 meters or more?
Exempt from 164.72 (Nav- safety equipment, charts or maps and publications if:
1. Used solely within a limited geographical area
2. Used solely for assistance towing
3. Used solely for pollution response
What must be used when fixing the vessels position on a chart?
- Electronic and other navigation equipment
- External fixed aids to navigation
- Geographic reference points
- Hydrographic contours
Other than for tankers when is an AB required to be at the wheel of a U. S. Vessel
On a US vessel of 100 GRT or more in narrow or crowded waters during low visibility
-Note: In all other circumstances there must be someone competent to steer the vessel in the wheelhouse at all times
What information must the person directing the movement of the vessel be provided with (Not the pilot)
- Vessels position each time a fix is plotted on the chart
- The evaluation of each closing visual or radar contact.
- Magnetic variation, deviation and gyro compass error
- Current, tides and predicted set and drift
What information must the pilot be informed of?
- Vessels draft
- Maneuvering characteristics
- Peculiarities of the Vessel
- Any abnormal circumstances that might affect the safe navigation
What factor must the pilot consider when setting the vessels speed?
- Visibility and weather
- Proximity of shore and marine structures
- UKC and Squat
- Proportions of the vessel compared to the channel
- Traffic density
- Vessels wake
- Current
- Speed limits
What are the licensed officer manning requirements on tankers or ITB/ATBs?
At least one engineer on watch in the engine room or ECR
At least two deck officers on watch, one of whom may be the pilot.
Under what conditions may an ATB/ITB use an autopilot?
If the autopilot is IMO approved and there is a helmsman present at the helm.
-except when operation in:
1. TSS
2. Safety Fairway
3. Anchorage ground or within .5 nm of the shoreline
When can a tanker or ITB/ATB use an autopilot with an INS?
Same as for autopilot without INS except:
Allowed in Traffic separation scheme and safety fairway if documentation shows accuracy and there is an immediate override control.
What are the bridge visibility requirements ahead from the conning station?
View of the sea surface ahead of 2 ship lengths or 500m whichever is less from dead ahead to 10 degrees on either side(5 degree obstruction limit)

What are the visibility requirement’s from the bridge wings?
Vision must extend at least 45 degrees on the opposite bow and through dead ahead to at least dead astern.
What are the visibility requirement’s from the main steering position?
From dead ahead to at least 60 degrees on both sides
What are the requirements for vessel at anchor?

2. Detect dragging anchor
3. Take the following action the prevent or stop dragging
- veer chain
-use second anchor
- get underway
What tests must be conducted no more than 12 hours before entering or getting underway?
- Primary and secondary steering
- All internal vessel control comes and alarms
3.Emergency generator - Storage batteries
- Propulsion ahead/astern
When must emergency steering be tested?
Within g48 hours prior to entry unless tested on a regular basis at least every 3 months
What charts and publications are required?
- Marine charts of suitable scale
- US coast pilot
- Coast Gaurd Light List
- Tide Tables
- Tide current table
- Must be currently corrected
What equipment is required for all vessels?
- Radar
- Magnetic steering compass
- Current and deviation table or graph
- Gyro compass with repeater at the steering stand
