Rules of the Road In All Cases Flashcards
THE 72 COLREGS
1972 Collision Regulations
How many feet in a meter
3.3’
Passes on the which side of the vessel
Right side
1 meter is how many inches
39 inches
Who do the International Rules apply to?
All vessels on high seas and in all waters connected therewith navigable by seagoing vessels
International Rules shall not interfere with
species rules made by an appropriate authority for example in the U.S. the Coast Guard made the Inland Navigation Rules Act of 1980 or just “Inland Rules”
The rule of good Seamanship and the GENERAL PRUDENTIAL RULE.
Nothing in these rules shall exonerate any vessel, owner, captain or crew from penalty for the neglect of complain with the rules, or by the ordinary practice of good seamanship or by the SPECIAL CIRCUMSTANCES of the case
What are Special Circumstances for the International rules
Special circumstance is considered a situation not covered by the rules. Since meeting (now called head-on), crossing and overtaking rules are designed for only two vessels interacting, three vessels coming together is considered a Special Circumstance and is not covered by any rule but this.
In following the rules, due regard shall be given to
all dangers of navigation and collision and to any Special Circumstance which may make a DEPARTURE from these rules necessary TO AVOID IMMEDIATE DANGER
A Vessel is
every description of water craft used or capable of being used as a means of transportation on water.
Examples are Hovercraft, Hydrofoils, Seaplanes, barges, canoes, bass-boats and even a manned tube being towed.
Powerboat
“Poer-driven vessel” mens any vessel propelled by machinery. Oars and sails are not considered machinery.
Sailboat
A “Sailing Vessel” is any vessel under sail provided that propelling machinery, if fitted, is NOT being used
Engaged in Fishing
any boat fishing with nets, lines, trawls or other apparatus that restricts maneuverability. A fishing boat using an anchor to hold position over. fishing hole is considered fishing.
Is a boat trolling for fish considered engaged in fishing?
No because it is felt that it can maneuver well.
Does Engaged in Fishing distinguish between commercial and recreation fishing
it does not. A sport fishing boat with a fish on the long is considered a fishing vessel, maybe a boat trolling for fish is as well.
Vessel Not Under Command
a vessel which through some EXCEPTIONAL CIRCUMSTANCE is unable to maneuver as required by the rules and is therefore unable to keep out of the way of another vessel. This is usually a mechanical or operational breakdown or defect from maneuvering or operation as an approaching vessel, unarmed of the problem, might expect. Vessels Not Under Command has right of way in most circumstances.
RAM
Restricted in Ability to Maneuver. A vessel, is unable to keep out of the way of another vessel because of the NATURE OF HER WORK.
Engaged in underwater dredging or surveying, laying cable or pipe, vessel working on Aids to Navigation, transferring cargo underway, military vessels launching planes or underwater operations.
Towing, BUT ONLY when it restricts ability to deviate from course.
CBD
Constrained by Draft. A power driven vessel which, because of her draft in relation to the depth of the water, cannot maneuver from the course she is following. Usually referring to a loaded tanker coming in or out of port. It is a temporary situation that may go away as the vessel reaches deeper water.
This definition is not used in Inland Rules due to, in part, the potential misuse by pleasure boats traveling the shallow road of the Intracoastal Waterways
Underway
Not at anchor or made fast to the shore or aground. A vessel dragging an anchor is under, as is a vessel being towed.
A vessel tied to a vessel that is docked is not underway. A vessel tied to an offshore mooring buoy is not underway.
There are two types Underway Making Way and Underway Not Making Way
Underway Not Making Way
becalmed, dead in the way, adrift, sinking or burning. Not making wake.
Underway Making Way
Moving with power through the water
Visual means
eyeballs, eyeglasses and binoculars only
Restricted Visibility
Any condition in which visibility is restricted by fog, mist, falling snow, heavy rainstorms, more or similar causes. This can happen on the brightest day or darkest night. Vessels close together in restricted visibility may still have visual contact. Captian’s call. Not fully defined for all conditions.
Conducts of Vessels apply to _______ conditions of visibility
Any
Look-Out
Every vessel is required to maintain a proper look-out AT ALL TIMES using eyes/ears and any other means available. This includes radar if you have one, and when it is in working condition.
Look outs must be well trained, rested, positioned, able to report quickly with no other duties.
A look-out is a person assigned to do nothing except be an extra set of eyes and ears for the captain. Chipping paint on the bow should not be considered as part of the duties of a look-out.
This rule does not require that every boat have a second person aboard or, if others are aboard that someone be assigned specifically to be a look-out. However, in the event of an accident the captain may be held negligent for not having posted a look-out.
SAFE SPEED
A safe speed is defined as one in which a vessel can take proper action to avoid a collision and TO BE STOPPED IN AN APPROPRIATE DISTANCE.
In determining what a safe speed would be, some of the considerations should be: state of the sea (including effect of current), traffic density, maneuverability, state of the visibility, and interference by BACKGROUND lights. Background lights refers to lights along the shoreline which may confuse the vessel or navigation lights you may be looking for.
Background Lights
Lights along the shoreline which may confuse the vessel or navigation lights you may be looking for.
Risk of Collision
Use all available means, including radar and lookout to help determine if there is a risk of collision. Any doubt, then there probably is. If there was a collision, there must have been a risk.
A risk exists if the bearing of an approaching vessel DOES NOT APPRECIABLY CHANGE.
In cases of large vessels, or vessels close by, even a large bearing change DOES NOT GUARANTEE that there’s no risk of collision.
CBDR
Constant Bearing - Decreasing Range
ACTION TO AVOID COLLISION
- Shall be positive and made with ample time.
- Must not result in another close quarters situation.
- If necessary to avoid collision OR ALLOW MORE TIME TO ASSESS THE SITUATION, a vessel SHALL slacken her speed or take all way off by stopping or backing her means of propulsion.
A vessel in a narrow channel or fairway shall keep to the _______ _______ side
Extreme starboard
A vessel of less than 20 meters in length, or a sailing vessel (of any size) shall not impede the passage of a vessel which
can safely navigate only within a narrow channel or fairway. (Also this is the big boats have the right-of-way rule)
________ vessels shall not impede any vessels in a channel.
Fishing (Engaged in Fishing)
A vessel shall not cross a narrow channel or fairway if such crossing
impedes the passage of vessels which can safely navigate only within such channel or fairway.
To avoid collisions you turn
right
As you pass, which side does the other boat pass on
port
Head on
you see both side lights of the approaching vessl
Side lights can overlap how many degrees?
6 degrees
If you only see one side light you are a ____ vessel
Crossing
When can you pass starboard to starboard?
When neither vessel needs to turn and there is amble space
Nearing a bend or an area of a narrow channel where other vessels maybe obscured by an intervening obstruction,
a vessel SHALL move with caution and sound one prolonged blast. Any vessel around the obstruction shall also give a prolonged blast.
Vessel shall avoid ________ in a narrow channel
Anchoring
Traffic Separation Scheme
- Pecking order goes away
- Stay in the proper lane
- Cross at right angles
- Enter and leave at small angles
