COLREGS QUIZ 1 MIDTERM

When two sailing vessels are approaching with risk of collision, the vessel with the wind on the port side shall:

• maintain her course and speed

• keep out of the way of the other vessel

• turn to starboard immediately
  

• signal the other vessel to alter course

If two sailing vessels have the wind on different sides, the vessel with the wind on the port side must:

• turn away from the wind direction

• continue on her present course
  

• keep out of the way of the other vessel

• sound a warning to the other vessel

The vessel that is to leeward is required to:

• maintain her course and speed
  

• keep out of the way of the windward vessel

• turn toward the wind direction

• signal for a change of heading

A vessel is considered overtaking when she approaches another from a direction:

• from a position showing both sidelights clearly visible

• less than 22.5° forward of the beam of that vessel
  

• directly abeam of the other vessel’s midship section

• more than 22.5° abaft the beam of that vessel

At night, an overtaking vessel would be able to see:

• only the port sidelight of the vessel ahead
  

• only the sternlight of the vessel ahead

• both sidelights of the vessel ahead

• the masthead light and sternlight together

If a vessel is unsure whether she is overtaking another, she should:

• assume she is overtaking and act accordingly
  

• maintain speed until visibility improves

• signal the other vessel for confirmation

• turn away to test the relative bearing

When overtaking another vessel, the overtaking vessel must:

• alter course toward the overtaken vessel’s beam

• maintain her course and speed at all times

• keep out of the way of the vessel being overtaken

• signal for the overtaken vessel to give way

The overtaking vessel remains responsible for keeping clear until she is:

• in visual contact with the sidelights of the other
  

• abeam of the overtaken vessel’s beam
  

• one cable length ahead of the overtaken vessel

• finally past and clear of the overtaken vessel

When two power-driven vessels are meeting on reciprocal or nearly reciprocal courses, each shall:

• alter her course to starboard to pass port to port
  

• alter her course to port to pass starboard to starboard

• maintain her course and speed until close quarters

• signal the other vessel before altering course

A head-on situation exists when a vessel sees the other:

• on her starboard bow at a wide angle

• directly ahead or nearly ahead of her position

• abaft her beam and closing in fast
  

• crossing from her port quarter direction
