Define “underway”

A

means vessel is not at anchor, or made fast by shore or aground

M Maneuverability of the vessel
L any lights or background scatter
W weather, sea and wind state

Q

Rule 9 Narrow channels

A

Always lay out Base rule first!!!!!!Ask if vessel is under 20m and if you can only safely navigate in Narrow Channel!

  • vessel less than 20m and sailing vessel shall not impede passage of power driven vessel which can ONLY SAFELY navigate in Chanel
  • fishing vessel shall not impede passage of any vessel navigating in narrow Chanel
    vessel shall not cross narrow channel if that impedes passage of vessel which can ONLY SAFELY navigate in channel
  • avoid anchoring
  • when overtaking must ask for permission if not enough space
30
Q

Rule 10 TSS

A

Always lay out Base rule first!!!!!! Ask if vessel is under 20m

  • proceed in appropriate traffic lane
  • join or leave at terminations or at small angle to general direction of traffic flow
  • cross at 90 degrees heading to general direction of traffic
  • unless for danger, do not exit TSS and traffic separating zone
  • vessel less than 20m and sailing vessel shall not impede power driver vessel navigating in TSS
  • fishing vessel shall not impede any vessel navigating in TSS
  • avoid anchoring
  • vessel less than 20m and sailing vessel shall use inshore traffic zone
  • vessel going to and from port or to pilot station can also use inshore traffic zone
  • navigate with extreme caution near terminations
  • RAM not to comply
31
Q

Learn Rule 8 Action to Avoid Collision

A
  • Action to avoid collision collision shall be positive, ample and with due regard to good seamanship
    any alteration of course shall be large enough to be readily apparent to other vessel
  • alteration of course may be most sufficient
  • vessel required not to impede shall take early and action to allow sufficient sea room for the safe passage of the other vessel

when the wind is on different sides, the vessel which has the wind on her port shall keep clear

when the wind is on the same, the vessel which has is windward shall keep out of the way
