The Rules in Context
Knowing the rules alone will not win races May avoid losing some!
The rules need to be used together with tactics and
execution skills

Focus on Part 2What do the rules (when boats meet) actually
require a boat to do?

The Red Light (Keep Clear) Rules
Between any two boats, one must ‘keep clear’
Imagine, that boat has its red light on
The red light switches instantly as the keep clear boat (and hence right-of-way) changes
10 - Port/Starboard
11 - Windward/Leeward
12 - Astern/Ahead
13 - Tacking
19.2(c) Continuing Obstructions
21 - Returning to start,
Penalties,
Backwards

But this can lead to a problem!
As the right-of-way changes instantly, a new give-way boat can find herself in an impossible situation.
This is solved in the rules, by introducing the concept of ‘room’.
However, when a boat is entitled to room, there is no change of right of way - the red light stays where it is.

The Amber Light (Give Room) Rules
Sometimes a boat must give room
Imagine that boat has a Amber light on
The Amber light only stays on for a limited time.

The Need to Give Room
In each of these cases, the right-of-way boat must give (mark) room, but the right-of-way does not change - the red light is not switched.

Summary So Far
First, we use the keep clear (red light) rules to determine which boat has right-of-way.
Then, we use the give room (amber light) rules to determine if a boat must give room.
Keep these two steps separate and in order
Just because a boat is entitled to room, she does not have right-of-way.

The zone is 3 hull lengths (unless changed in SI)
Applies as first boat enters the zone

Mark- Room
Mark Room (Definition) - 2 phases.Room to sail to the mark (seamanlike direct course to the mark)Room to sail her proper course while at the mark (including tacking, gybing)

Rule 18 - Marks
If you are the outside boat you must give room unless:
You were ahead at the three length zone (when about to round), have not sailed out of the zone, and neither boat has passed head to wind [18.2(b & c)]
Yellow is not entitled to room as she was clear astern when Blue entered the zone.

Rule 18 - Marks
If you are the outside boat you must give room unless:
You were ahead at the three length zone (when about to round), have not sailed out of the zone, and neither boat has passed head to wind [18.2(b & c)]
Yellow is entitled to room inside Red because Red sailed out of the zone and Yellow was overlapped when she re-entered

Rule 18 - Marks
If you are the outside boat you must give room unless:
You were ahead at the three length zone (when about to round), have not sailed out of the zone, and neither boat has passed head to wind [18.2(b & c)]
Blue looses all entitlement to room as soon as she passes head to wind.
She must keep clear while tacking.

Rule 18 - Marks
If you are the outside boat you must give room unless:
You were unable to give room from the time the overlap began [18.2(e)]
Yellow is fast and establishes on overlap on Blue before the zone.
However, Blue is unable to give the room and so Yellow is not entitled to room.

Rule 18 - Marks
If you are the outside boat you must give room unless:
You were the inside boat when you entered the zone and have not sailed out of the zone [18.2(b & c)]
Blue was outside when Yellow entered the zone, so she is not entitled to mark-room.
Yellow may risk breaking rule 18.4.

Rule 18 - MarksThere are times when rule 18 does not apply, so, an outside boat does not have to give room.
You are on opposite tacks on a beat [18.1(a)]
Yellow is not entitled to room. This is just a port-starboard situation.

Even if the boats have over-stood the mark so they are no longer on a beat, Yellow is still not entitled to room

Rule 18 - MarksThere are times when rule 18 does not apply, so, an outside boat does not have to give room.
You are approaching a starting mark surrounded by navigable water, to start [Section C - preamble]
Approaching the line to start, Yellow is not entitled to room to pass the committee boat starting mark.

Rule 18 - Marks - Summary
You were ahead at the three length zone (when about to round).
You were unable to give room from the time the overlap began.
You were the inside boat when you entered the zone and have not sailed out of the zone.
If you are the outside boat you must give room unless:
You are on opposite tacks on a beat
You are opposite tack and one, but not both boats must tack to round the mark
You are approaching the starting line to start.

Rule 18.3
Rule 18.3 - Tacking at marks, is affected by the 3LZ but also now applies when the tacking boat changes tack in the zone. (Used to be completes her tack)
Fetching -
A boat is fetching a mark when she is in a position to pass to windward of it and leave it on the required side without changing tack.

Rule 18.3
Rule 18.3 - Tacking at marks, is affected by the 3LZ but also now applies when the tacking boat changes tack in the zone. (Used to be completes her tack)
Even though Blue tacked well clear of Yellow, she broke rule 18.3 when she caused Yellow to sail above close-hauled.

Rule 19 - ObstructionsIf you are the outside boat you must give room unless:
You were unable to give room from the time the overlap began [19.2(b)]
Blue has just established an overlap. Yellow only has to give room if she is now able to do so.
There is no zone at obstructions

Rule 19 - Obstructions
If you are the outside boat you must give room unless:
You are on opposite tacks and sailing less than ninety degrees from the wind [Definition of Overlap]
Blue is sailing less than 90 deg to the true wind, so is not entitled to room.

Rule 19 - ObstructionsIf you are the outside boat you must give room unless:
Passing a continuous obstruction and the boat astern established the overlap when there was no room to pass in safety [19.2(c).
When Blue established the overlap there was no room for her to pass in safety.
She is not entitled to room and remains the boat required to keep clear

Position at closest point Select the most useful (two) positions before the closest point.
Positions as right-of-way changes or first boat enters the zone, for example Position soon after
Which Rules Apply - At each step1. Identify which boats have to Keep Clear at each position2. Do any of the Give Room rules apply?3. Do either of the Proper Course rules apply?4. Has there been any Interference or Contact?
Has a rule been broken - test questions: 1. has the boat required to keep clear, caused the ROW to alter course or collide?2. has a boat required to give room failed to do so?3. has a restricted boat sailed above her proper course?4. has a boat interfered or had contact that could have been avoided?
• Should any boat be exonerated? rule 18.5 or 64.1(c)• Did contact result in damage or injury? rule 14
