Navigation Rules Flashcards
Rule 5
The Lookout Rule:
Every vessel shall at all times maintain a proper lookout by sight and hearing as well as by all means available appropriate in the prevailing circumstances and conditions so a s to make a full appraisal of the situation and of the risk of collision.
Rule 12: Sailing vessels with the wind on different sides (port tack/starboard tack)
The vessel on a starboard tack is the stand-on vessel and the that on a port tack is the give-way vessel. The Give-way vessel should make their maneuver early so the stand-on vessel understands their intentions.
Rule 12: Sailing vessels with the wind on same side (leeward/windward)
The boat to windward is the giveaway vessel, the vessel to leeward is the stand-on vessel. The windward boat would most often alter course to pass astern of the stand-on vessel.
Rule 12: Sailing vessel on port tack cannot determine windward sailing vessel’s tack
If a sailboat on port tack sights another sailboat approaching from windward an cannot determine the approaching vessel’s tack, it should keep clear.
Rule 13: Overtaking
When one vessel is overtaking another, the overtaking vessel must keep out of the way of the vessel being overtaken. The is one of the few instances in which a port-driven vessel is not the give-way vessel with respect to a sailing vessel. A sailboat under sail must keep clear when overtaking a power-driven vessel. A vessel is considered to be overtaking you if it is approaching within an arc between your stern and 22.5 degrees aft of your beam on either side.
Rule 14: Power-driven vessels approaching each other head-on
Both vessels turn starboard and pass each other port side to port side.
Rule 15: Power-driven vessel with another power-driven vessel on starboard side
When two power-driven vessels are crossing, the one that has the other vessel on its starboard side gives way.
Describe appropriate actions to be taken when sailing in the vicinity of commercial traffic, including responding to a danger signal.
Some areas impose security zones around large commercial vessels and vulnerable shore establishments. Try to give a wide berth to commercial traffic and stay 500ft away from Naval vessels. Pay attention to danger signal, 5 short blasts. It means a vessel is unsure of the intentions of another or is in doubt whether sufficient action is being taken to avoid a collision.

Describe the purpose of a float plan.
The purpose of a float plan is to provide information that will be helpful to authorities and others in the event you get into difficulties. The more detailed and specific information it contains, the more useful it will be.
What information should be included in a float plan?
Planned itinerary, a description of the boat, the number of people on board and their names, and your cell phone information. Set a time at which this contact should begin to make calls and to whom if you haven’t checked in. Be sure to contact your shore person as soon as you have completed your journey or if you make any change in plan.
Who should a float plan be submitted to?
Designate someone to be your shoreside contact. Don’t try to give to the USCG; it doesn’t accept them.
What do red lateral aides to navigation indicate?
Red, right, returning! Red marks indicate right hand side of a channel when you are returning from the sea or moving away from a large body of water to a smaller body of water.
What do green lateral aides to navigation indicate?
Green marks indicate the left-hand side of a channel when you are returning from the sea.
