ASA 103By the lee - ANSWERS-Sailing on a run with the wind on the same side as the
mainsail.
Nautical mile - ANSWERS-6,076 feet. A knot is one nautical mile per hour.
Interestingly, and for comparison's sake, a mile is 5,280 feet, meaning wind speed
measured in knots is 15% greater than measured in miles per hour.
Heaving to - ANSWERS-To set the sails in opposition so the jib is on one side and
the mainsail on the other. This is achieved most often by tacking and leaving the
jib sheet cleated on the new tack. Adjust mainsheet so boat is on a close reach.
Adjust helm as needed and lash wheel so it can't move.
Navigation Rules 16,17 and 2. - ANSWERS-These are all related. Rule 16 states the
give way vessel must take early and substantial action to keep well clear of the
stand on vessel. Rule 17 requires the stand on vessel to maintain course and
speed. Rule 2 overrides these if a collision is imminent, requiring vessels to take
whatever action necessary to avoid a collision.
Navigation Rule 5 - ANSWERS-The Lookout Rule. This rule requires all vessels to
maintain a proper lookout by sight and sound and all means available, at all times.
Navigation Rule 12 (Sailing Vessels Only) - ANSWERS-Starboard tack has right of
way. The position of the main boom determines which tack you are on. If it is on
,the port, even if you are sailing by the lee, you are on starboard tack. The other
rule is windward/leeward. For boats on the same tack converging, the boat to
windward is the give-way vessel, and would most often alter course to pass astern
of the stand-on vessel.
Rule 13: Overtaking - ANSWERS-The overtaking vessel must give way. A vessel is
considered overtaking if it is within an arc 22.5 degrees aft of your beam. The
overtaking rule applies whether under sail or power.
Rule 14: Head-on situation - ANSWERS-Both boats turn to starboard
Rule 18: Responsibilities between vessels - ANSWERS-Establishes a hierarchy of
privilege as follows:
1. Boat not under command, unable to maneuver
2. Restricted in ability to maneuver, such as dredges, tugboats towing another
vessel. They are required to display special shapes or lights to advise other vessels
of their status.
3. Constrained by draft: such as large container ships
4. Engaged in fishing
5. Under sail
6. Under power. This includes sailboats under power even if sails are up.
Rule 9 - ANSWERS-Narrow channels: A vessel less than 20 meters in length shall
not impede the passage of any other vessel navigating within aa narrow channel
or fairway.
, Security Zones - ANSWERS-Do not approach within 100 yards of a naval vessel
longer than 100 feet.
Rule 10 - ANSWERS-Traffic separation schemes: A vessel operating in a traffic
separation scheme is required to use the lane designated for its direction of
travel--In most of the world, that means keep to the right and slower vessels to
the right in that lane.
Rule 10 requires crossing a traffic lane at a right angle.
Sailboats are not required to use the separation scheme if an inshore zone is
available. But if are using one, use appropriate lane and act as if you are in a
narrow channel.
Danger Signal - ANSWERS-Under International and US Inland Rules, five short
blasts mean, "I am unsure of your intent."
Action Signals - ANSWERS-Under both rules, three short blasts means I am
operating stern propulsion. One short blast means, under International Rules, I
am altering course to starboard; under Inland Rules, it means I intend to leave you
to port. Two short blasts means (International Rules) am altering course to port,
and (US Inland Rules) I intend to leave you on my starboard side.
Channel 13 on VHF - ANSWERS-The channel used by most commercial vessels to
communicate bridge to bridge.
