SLIFF AOS03 BARGING AT THE START


[MUSIC] Welcome to the SLIFF Sailing School in the
Skagway Sim at Blake Passage. This is our third video dealing with Right of Way during
the start. We are going to take the basic rules and show how they apply during the start
with a special emphasis on barging. This includes some interesting video and I hope you enjoy
it. Lets continue removing the mystery of the
Art of the Start [MUSIC] Because of the starboard tack right of way,
almost all boats on a start will be approaching the start line on starboard tack. The starboard end of the start line is shown by the green triangle. You can see that the wind
is set perpendicular to the start line. Boats can cross the start line anywhere along
its length. Depending on the wind, most of the courses sailed at SLIFF generally favor
starting as close as possible to this green buoy and this is called the favored end. The green dashed lines are called starboard
lay lines and approximate the course that a boat would approach the start line sailing
close to the wind or close-hauled. These lines approximate a 45 degree angle to the true
wind. They will shift in either direction as the wind changes from perpendicular to
the start line. Boats sailing in the green area and sailing
close-hauled will have tracks that parallel the lay lines. All three boats are sailing
a close-hauled course to the start line. Boats approaching the start line from the
yellow area are also on starboard tack. I use yellow to mark this area because these
boats have to be cautious about barging. The definition of barging is approaching
the start line at a wind angle greater than closed-hauled, which really means sailing
off the wind from a close hauled point of sail. Sailing parallel to the start line gives
you the most boat speed but also the most exposure to right of way problems. This right of way exposure goes back to the
original Leeward Boat Right of Way and Overlap. Let’s look at this from the position of
the yellow boat. The left side of the yellow boat is leeward. From our definition of overlap
you can see the entire fleet is forward of the line perpendicular to the stern of the
yellow boat. The yellow boat is overlapped to leeward by the entire fleet and is required
to yield right of way to every one of them. The orange boat is not in a much better position. Approaching the start line from a high wind
angle, though barging, is not necessarily illegal or a bad thing. You see boats start
like this all the time in Second Life sailing. It only becomes a problem when somebody gets
in the way. Let’s look at what the yellow boat and orange boat are trying to do. Both boats plan to pass in front of the white
boat. All three boats are aiming for the same spot. That is a lot of hardware converging
on the same spot and the boat with all the right of way is the white boat. The white boat is planning on shutting off the start line from the barging zone. If the two barging boats continue and either
cause contact with the white boat or force it to change track to avoid contact, they
have committed the foul of barging. Remember, neither of the two
non right of way boats are entitled to room at the start mark. It is one thing to create diagrams and possible
situations. It is another to see it occur and capture it on video. You see this type of start all the time in
Second Life. The wind is perpendicular to the start line. The fleet gathers off to the
west so it can come racing down on starboard tack and on a beam reach. Once the boats turn inbound they are going about
as fast as the boat will sail. They bunch up, bow to stern. Maybe an overlap or two thrown
in to make it more interesting. This type of start only works when no one
gets in the way. This is the boat to watch because she is going
to get in the way and do so will all the right of way in the world. The intent of the racer
is to turn up the starboard lay line and cut the fleet off from the line. There is no right
to room at the mark during the start. She times this start perfectly. An interesting video and it is happening very
quickly. I doubt any of these racers have seen this before. Let’s go through the final
stages of this start. Four seconds to the horn, this boat has the
right of way. These two boats, especially the lead boat
is in a bad situation. Neither boat can pass cleanly in front of
the ROW boat and because of the speed, the lead boat is too close to pass behind.
The only choice is to break off and miss the start. The second boat can still fall off and go
behind the right of way boat. At the horn, the lead boat can still veer off,
miss the start and avoid contact with the ROW boat. It is more difficult because now the second
boat has overlapped to windward by the trailing boat. He does have right of way but must maneuver to give the trailing boat time to respond. The trailing boat can not go behind and must
veer off and miss the start. Now the right of way boat has to take action.
Once it sees the other boats are not complying with the rules, it should turn to avoid contact. The boat needs to protest and hope the Race
Director is watching. We have covered a lot today. If you can, visit
us down at the Skagway Sim. We are a friendly bunch with a passion for sailing,
a passion for racing and a passion for the Bandit IF. Enough work, let’s GO SAIL
