The Racer’s Corner – The Start and On the Beat

So you didn’t do as well as you wanted to in the first race of the season. This month we will review some tips that are sure to improve your ranking in the next race, the Huddleston Cup, July 24 & 25.
Tip Number One: The Start
The start is the most important part of any race and many novice sailors do not understand the significance of the start in relation to the rest of the race and this is where they go wrong.
The start is the single most important part of the race for most sailors as if they are only moderately skilled, a bad start will break them. Only very skilled and experienced sailors can claw back to the top from a bad start.I am expecting you to be quite good, but always coming between last and middle place. You want to start to get some wins under your belt.
Well look no further, the start is the most important part of the race.
Here is a list of strategies that you should use on the line if you want to have a good start and a potentially good race:
• Get a stop watch! – All serious sailing racers need a stop watch in order to start on time and in the right place without being caught unawares
• Learn the Flag types – The flags are there to tell you what is going on in a race. So not knowing them is hardly going to help you understand what is going on in the race. It is highly advisable to find a good rulebook from your national sailing organization or the ISAF (International Sailing Federation) and learn all the flag types that will be shown at any given race. Preparation make Perfect!
• Learn where the marks are – If you are thinking of club racing regularly, then you should learn where the common marks that are used for racing actually are so that when the committee boat shows the marks you don’t have to glance at a map constantly during the race.
• Do a Transit – This little known tactic is a very useful technique in order to have a good start. A transit is where you put the boat between the committee boat and the pin buoy and look for a recognizable object on the other side of the pin. This tells you exactly where the starting line is and if there is a black flag shown, you will know whether you are over the line or not.
• Find out if there is a bias – A biased line is one in which a certain tack is favoured. To find out if there is a port bias, a starboard bias or if it is square (no bias), you can do it accurately or roughly. Doing it accurately requires a compass. Go along your transit and note the compass bearing. Then add 90 degrees to that bearing and turn to that heading. If the boat tacks then the current tack is the favoured tack and the bias. If the boat doesn’t tack then the current tack is the favoured tack and the bias. If the boat goes head to wind then there is no bias and it is a square line. You can roughly do this by seeing if you are beating up one end of the line and broad reaching down the other end. If it is a square line then you should be beam reaching from one end to the other
Starting Position – This is also highly important for competitive racing. If there is a bias then most of the boats will be there. If you don’t want to be in a scrum and get a rubbish start, then start slightly lower than the bias end or start on the opposite tack and then tack on to the biased tack after horn goes off. By doing this you will have your own unique heading and start.
If you can master most of those tactics, then your starts will become better and better. Make sure that you go over the line on the horn and at full speed as well as using the above tips.
So now the boat has crossed the line. You are on the beat! Tip Number Two: The Beat
This is the hardest point of sailing to master and this is also where the fleet spreads out with the well trimmed and faster boats at the front while the untrimmed and slower boats lag at the back.
Here are some great tactics to try and improve your position on the beat.
• Keep the boat flat! – Another incredibly common past time that I see on the race course is boats heeling constantly though out the race. This is terrible for boat speed as the sail is pulled away from the wind. Make sure that the boat is flat at all times. To actually achieve this make make sure boat crew members are hiking out of the boat in a comfortable position. If this doesn’t help then let out some main sail and pinch (go further up wind), this should bring down the heel. the moment this happens pull the main sheet back in so that when the boat is flat the mainsail is fully in. This has the effect of a massive pump on the boat, which causes a burst of acceleration. Continue to do this throughout the beat and you will find yourself overtaking everyone who is heeling constantly, greatly improving your position. You can also use the kicker and cunningham in especially high winds to depower the sail and keep the boat flat, but you must remember to remove the kicker and cunningham when the wind dies down or there is a lull.
• Sit forward in the boat – When the boat is not heeling your crew should be sitting on the centreboard and you should be sitting up against the shroud. If you both sit forward the stern comes out of the water and the boat is no longer hampered by an extra dead weight in the water.
• Make sure that the slot is trimmed – The slot is the distance between the Genoa and the mainsail. If the slot is too small the airflow becomes constricted and the front bottom of the mainsail begins to luff. If the slot is too large the Genoa begins to luff. The slot must be trimmed correctly so that the Genoa is about one and a half inches off the leeward shroud so as to provide optimal airflow. This slot distance changes with wind speed so it must be constantly watched by the crew.
• Take lifts and avoid headers – Lifts and headers are where the wind changes direction. If the change is more to windward, it is called a lift and if the the change is more to leeward it is called a header. You should always take lifts and avoid headers by changing the boat’s direction. In a lift turn windward and in a header bear away. In big lifts you should always expect a large header, which could make you tack so be careful about overshooting and taking the lift too far. Lifts are useful by taking you more windward of your opponent, which means closer to the windward mark.
Follow these tips and you are sure to improve your position
Remember that a season champion for both Cruiser and Dinghy class racers will be awarded at the end of the season. The top scores for each skipper for 50% of the races in the 2010 season will count toward the calculation for the season championship in each class.

Revised Racing Schedule – Notice Changed Dates

Mother Nature has thrown a wrench into the racing schedule for the summer of 2010.  The lake is still 20 feet above summer pool.  This has the ramp turn around and the dock anchors under water.  We cannot reattach the dock until the lake level is below the anchors and the ground around them dries out.  We would also be wise to not get to much weight on the asphalt part of the drive, until the ground under it has had a chance to dry out.  Therefore, we are going to postpone the first two races of the season and begin the season with the Yankee Doodle on Sunday July 4.  We will again this year have a catered meal of bar-b-qued pork and the fixings.  Registration for the Yankee Doodle is $25, which includes a dinner for the captain.  Additional meals are $8 per person.  Come out and join the fun.

The revised race schedule will be as follows:

Yankee Doodle – July 4

Huddleston Cup – July 24 & 25

The Karl Millen – August 7

The Jolly Roger (Long Distance Race) – August 28

The Dixie Cup – September 5

The Great Minnow – October 2

The Great Minnow is a one day race this year.  So if fear of committing to two days has held you back in the past come on out this year and join in the fun.

The Racing Corner – The Start by Doug Roberts

The Start
The start of a sailboat race is one of the most exciting and demanding moments in a sailboat race. A good finish requires a good start. A good start requires judgment, timing, teamwork, and full understanding of how your boat will react in the existing wind conditions. It requires an understanding of wind and weather; and knowledge of strategy, tactics, and rules. Starts demand dexterity at close quarters, maneuvering and the ability to stay cool and concentrate in an environment packed with distractions. One of the keys to a good start is to ensure it sets you up well for the first leg of the race. Think through your strategy to rounding the first mark.
There are two basic approaches, follow the fleet or take a contrarian course.
1. Following the fleet you will ensure that you receive the same advantages of wind puffs and disadvantages of the lulls as the rest of the fleet. You will also have to guard against being in the wind shadow of another boat when following the fleet. Most of the times the fleet will start on a starboard tack which gives each of them the right of way over those on the contrarian start tack.
2. The contrarian start generally will start on a port tack and place you on a tack for a longer run before you tack, and that may mean a longer distance to the first mark. You will be dependent on a different set of advantages of wind puffs and disadvantages of the lulls as the rest of the fleet, which may or may not favor you. You are generally not affected by the wind shadow of other boats on this start. It could set you up for a longer run on a starboard tack with more speed as you approach the first mark.

Rounding the mark
It is often better to come into the mark wide and exit the mark tight. Remember if you are overlapped by a boat on your inside in the three length zone around the mark, you must give room to that boat to round the mark. Likewise if you are coming in wide and fast it is very possible that you can overlap a boat and cause that boat to alter its course to allow you room on the inside.

There are several copies of a Racing Tactics DVD in the shed at the club. You are welcome to borrow a copy of the DVD, but please be kind and return it within two weeks.

To help racing sailors get familiar with the Racing Rules of Sailing, UK-Halsey Sailmakers presents a series of animated race course situations http://www.ukhalsey.com/RulesQuiz/quiz_list.asp

A new regatta is added to the schedule this year. A long distance race will be held on June 19. This will be a little more relaxed race with longer legs of the race. Come out and join the fun.

The Challenge of Racing – by Doug Roberts, Racing Chairman

Racing Corner Month 5
The challenge of sailing is to get your boat to go from point A to point B, even when the wind will not cooperate. Racing helps force you to learn how to get your boat from point A to point B to point C in as short of a period possible. The fastest way to learn new skills is by following a better racer (and it is great way to place in the race). These guys are often better for a reason, and there is much to learn. Follow them, figure out why they went the way they did, or why they didn’t do what you would have done. If you can’t figure it out on your own, ask them after the race. Most of the club members are happy to share tips with more than just a quick answer. Many times, when a person begins to race, they will follow a faster boat and finish second or third. However, for some reason this stops, and they drop back in the fleet. It may be that “beginner’s luck” runs out. But, more than likely, they just stop following faster racers.

More definitions

Finish – A boat finishes when any part of her hull, or crew or equipment in normal position, crosses the finishing line in the direction from the last mark either for the first time or, if she takes a penalty, after complying with rule 31.2 or rule 44.2.

Obstruction – An object that a boat could not pass without changing course substantially, if she were sailing directly toward it and one of her hull lengths from it. An object that can be safely passed on only one side and an area so designated by the sailing instructions are also obstructions. However, a boat racing is not an obstruction to other boats unless they are required to keep clear of her or give her room.

Proper Course – A “proper course” is one the boat would sail to finish as quickly as possible. Since different sailors often have different ideas of the quickest route to get to the finish line there can be more than one proper course for a boat at any particular point in time. Thus, two boats sailing side by side may have different proper courses because of differing views on how best to get to the finish line as quickly as possible.

A boat has right of way when another boat is required to keep clear. The following rules cover some special situations where a boat must keep clear.

  • If you cross the starting line too soon before the start, you have to go back behind the line and start again. While going back, you have to keep clear of all boats that have started (Racing Rule 20).
  • If you hit a mark while racing, you must take a penalty as soon as possible by doing one 360-degree circle (Racing Rule 31). While doing your penalty circle, you must stay clear of all other boats.
  • If you foul another boat while racing, you must take a penalty as soon as possible by doing two 360-degree circles, or turning 720 degrees (Racing Rule 44). While doing your two penalty circles, you must stay clear of all other boats.

Racing Rule 14 – Avoiding Contact You must avoid contact with other boats if possible. Even if your boat has right of way you must avoid contact, but you don’t need to act until it becomes obvious that the other boat is not going to keep clear.

POYC Racing Rule 2010 – Have fun and learn while racing. This is the year to commit to having fun with your boat or one of the club boats and race. Club racing is meant to be fun and help develop skills and that will be the focus of the race program this year. If you don’t feel comfortable racing your own boat, come on out to the club on race day. Many racers are always glad to have crew aboard on race day. Come out to the club on race morning and it is guaranteed you will be asked to either crew on a boat or work the committee boat.

Now you are ready to start racing. But if you want that extra little boost of confidence, come out for the introduction to sailboat racing class May 13.  We will talk about the rules, the marks, as well as racing strategies and tactics with some of the best racers in the club. In the mean time here is a great link to learn more about racing http://www.racing.sailingcourse.com/index.html

Racing Corner – Month 4 Taxonomy of the Race Course by Doug Roberts

Taxonomy of a Race Course

Here are some of the terms you may hear when people talk about race courses.
Committee Boat: The end of the starting line marked by the Race Committee boat.
Usually the starboard end of the line when facing upwind. The Committee Boat flies the flags and sounds the horns to signal the racers and records start and finish times.
Pin: The end of the starting line marked by a buoy. Usually the port end of the line when facing upwind.
Open Line: Racers are allowed to cross the start/finish line during the race. This is the case unless the Sailing Instructions say otherwise.
Closed Line: Racers are not allowed to cross the start/finish line while racing except while starting or finishing their race. This is sometimes called a Closed Gate.
Weather Mark (or Windward Mark): The mark buoy that is the most upwind.
Lee Mark: The mark buoy that is the most downwind.
Gybe Mark: The second mark on a triangle course, where you have to gybe to stay on the course.
Windward Leg: A leg of the race where you must sail closehauled and tack to reach the next mark.
Reaching Leg: A leg where you can sail on a reach and do not need to tack or gybe to reach the next mark.
Downwind Leg: A leg where you must sail more or less straight downwind to reach the next mark and you may need to gybe one or more times.
Marks Left to Port: When you round a mark, you pass it so that the mark stays on the left side of your boat. Most fleet racing courses are designed this way, particularly for the first windward mark.
Marks to Starboard: When you round a mark, you pass it so that the mark stays on your right side. Match race courses are designed this way, particularly the America’s Cup.

2010 Port Oliver Yacht Club Race Instructions
These instructions are intended to provide information necessary to coordinate and participate in the POYC racing program. A good understanding of these instructions will help prevent some conflicts during the season.

A. A race should be fair and sporting for all competitors. Good sportsmanship is expected from all participants.
B. All boats entered into a race shall be subject to the direction of the Race Committee (RC). However, it shall be the sole responsibility of each skipper to decide whether or not to START or CONTINUE a race.
C. All races will be conducted under The Racing Rules of Sailing (RRS), the class rules, and rules modifications as determined by the POYC Race Committee.
D. All required safety equipment shall be carried aboard all boats participating in a race. Each skipper is responsible for the safety of his/her crew and boat. If the Race Committee determines that conditions require the use of life preservers, it shall hoist the Y flag or a life preserver/vest.
E. Races shall be sailed back-to-back each racing day.
F. A minimum of four boats are required to form an official race class.
G. P.O.Y.C. Race Courses are typically windward/ leeward or triangle courses. If other course configurations are used, the configurations must be explained in the skippers meeting before the race.
H. Starting signals shall be covered in the skippers meeting. The starting signals usually consist of a combination of Class flags, a Preparatory (P) flag, and sounds. The sounds are optional.
The class flags are as follows:
a. Red flag – Cruiser
b. Blue flag – Dinghy
c. Yellow flag – Multi-hulls

The starting process is as follows:

d. 5 minutes before the start, the class flag is raised and a warning signal may be sounded.

e. 4 minutes before the start, the P flag (blue with a white square in the middle) is raised and a warning signal may be sounded.

f. 1 minute before the start, the P flag is lowered and a long warning signal may be sounded.

g. The class flag is lowered to signal the start the race. A warning signal may be sounded.

I. The RC will hail early starters, but the burden of a proper start is the responsibility of the skipper.

J. The RC may score all boats remaining on the course 20 minutes after the first boat of the class crosses the finish line as DNF (Did Not Finish) and recall the boats to prepare for the start of the next race.

K. The handicap factors used will be the Portsmouth Yardstick, D-PN factors. No penalty for under-crewed boats. If your boat has modification factors, please indicate on the registration form.

L. Awards will be given for individual races as well as a season champion for both Cruiser and Dinghy class racers. Multi Hulls awards will be available for individual races, when a class exists.

M. The top scores for each skipper for 50% of the races in the 2010 season will count toward the calculation for the season championship in each class. Season points shall be awarded for each race of the day as follows:

a. 1st place = 1 point
b. 2nd place = 2 points
c. 3rd place = 3 points
d. So on through all boats placing.
e. DNF shall be awarded the number of boats finishing + 1

If there is a tie between two or more boats, each boat’s race scores shall be listed in order of best to worst, and at the first point(s) where there is a difference the tie shall be broken in favor of the boat(s) with the best score(s). No excluded scores shall be used. If a tie remains between two or more boats, they shall be ranked in order of their scores in the last race. Any remaining ties shall be broken by using the tied boats’ scores in the next-to-last race and so on until all ties are broken. These scores shall be used even if some of them are excluded scores.

N. Protests may be filed with the RC at the conclusion of each race. Hearing of protests will be held at the end of the race day. Please keep in mind rule 14 “You must avoid contact with other boats if possible.” Intentional violation of this rule will disqualify you from filing a protest.

Committee boat

The challenge of sailing is to get your boat to go from point A to point B, even when the wind will not cooperate. Racing helps force you to learn how to get your boat from point A to point B to point C in as short of a period possible. The fastest way to learn new skills is by following a better racer (and it is great way to place in the race). These guys are often better for a reason, and there is much to learn.

The Racing Corner – Part Two

Racing Corner Month 2 by Doug Roberts – POYC Racing Chair

Why we race sailboats.

It’s about being with people who share our interests. It’s about being with friends and making new friends. It’s about adding meaningful memories that will last a lifetime. Our sport is about respect for the rules, respect for fellow competitors and respect for traditions. Sailboat racing is a shared experience. The bonds created on the course outlast the day of competition. Make a commitment to yourself to join this great sport this year.

Rounding Marks

Room at the Mark!!!! You will hear this on the race course. Giving room is one of the areas where it seems sailors have little room for forgiveness. Room is the space needed by a boat in the existing conditions to perform a particular maneuver promptly and in a seaman-like way.

Of all the racing maneuvers you should practice, rounding the marks is where you should definitely sharpen your skills, because many gains and losses are made at mark roundings. Often a pack of boats will approach the mark, basically tied with each other. Because of the nature of the rounding, someone will come out on top, and depending on the number of boats and the skill of the skippers, the last boat could end up 20 boat lengths behind.

There are three “maneuvers” for which room may be required:

(1) keeping clear of a right-of-way boat,
(2) passing a mark or obstruction or
(3) tacking to avoid an obstruction.

There are several important elements within the definition of “room.”

· One element is “existing conditions,” so that the space required for a particular maneuver will vary depending on what conditions (wind and sea) exist at the time (and may also vary depending on the size and type of boats involved).

· A second element to “room” is “seaman-like way”. A boat will only be entitled to enough room to complete a particular maneuver properly (and will not be entitled to the room necessary to “mess up” the maneuver).

· A third element is “promptly,” so a boat is only entitled to the space to make a particular maneuver “promptly” and may not delay in making a particular maneuver if that causes her to take more room than she would have needed if she had acted promptly.

Definitions

· Three-length zone – The three-length zone is an area that extends from a mark or obstruction on the race course that is equal to three boat lengths. The radius of the Zone is equal to three boat lengths.

· Mark – A mark is any object that according to the sailing instructions must be passed on a particular side, including the marks which indicate the ends of the starting and finishing lines. The anchor line of a buoy that is a mark (similarly, the underwater area around an island that is a mark) is not considered part of the mark. So if the island is a mark and you run aground, you do not need to serve the penalty for hitting a mark (unless of course you run aground so hard you hit dry land).

Three More Rules

* When you’re tacking, you must keep clear of all other boats from the time your boat passes head to wind until it is on a close-hauled course (Racing Rule 13). Look around before you tack to make sure you don’t tack in the way of another boat.

* Whenever you are the right-of-way boat and want to turn, you must give the other boat a chance to keep clear (Racing Rule 16). You cannot make an abrupt turn that allows no opportunity for the other boat to stay out of your way.

* When a boat reaches the three-length zone from a mark or obstruction, it has to give boats overlapped inside it room to round or pass the obstruction (Racing Rule 18). The outer edge of this zone is three boat lengths from the mark. This Rule is switched off at starting marks, and between boats on opposite tacks at the windward mark.

In the newsletter next month we will cover finishing the race, avoiding obstructions, and sailing a proper course. See you at the March meeting and work party.

Racing Corner #1 by Doug Roberts

Racing Corner Month 1 by Doug Roberts – POYC Racing Chair

This is a year to commit to having fun with your boat or one of the club boats by racing it. Club racing is meant to be fun and help develop skills and that will be the focus of the race program this year. When a sailor begins to race, many questions come up, such as, “How do the sails work,” “Why do I always get passed rounding the mark,” and “What is rounding the mark?” This section of the newsletter over the next few months should provide some quick answers to basic questions in a relatively painless and comprehensive way. Once you look behind the curtain, you will find that sailboat racing is not all that mysterious and you can have great fun.

Let’s start with some definitions.
· Tack, Starboard or Port – Simply a boat is on a tack which is opposite of the side its main boom is on. If the main boom is on the port (left) side the boat is on a starboard tack. If the main boom is on the starboard (right) side the boat is on a port tack
· Leeward and Windward – A boat’s leeward side is the side that is away from the wind. However, when sailing downwind, her leeward side is the side on which her mainsail lies. The windward side is the side that the wind hits first or when sailing downwind it is the side opposite of the main boom. When two boats on the same tack overlap, the one on the leeward side of the other is the leeward boat. The other is the windward boat
· Keep Clear – One boat keeps clear of another if the other can sail her course with no need to take avoiding action and, when the boats are overlapped on the same tack, if the leeward boat can change course in both directions without immediately making contact with the windward boat

· Overlap, Clear Astern and Clear Ahead – One boat is clear astern of another when her hull and equipment in normal position are behind the aftermost point of the other boat’s hull and equipment in normal position. The other boat is clear ahead. Boats overlap when neither is clear astern.

Rules of Sailboat Racing:

There are three guiding principles that underlie the Racing Rules. All competitors are expected to compete within the framework of sportsmanship, fair sailing and helping those in danger. If you’re new to racing, you only need to know a few basic rules to handle most situations you’ll encounter on the race course. As you gain more experience, you’ll learn more about the subtleties and limitations of these and other rules.

Racing Rule 14 – Avoiding Contact

You must avoid contact with other boats if possible. Even if your boat has right of way you must avoid contact, but you don’t need to act until it becomes obvious that the other boat is not going to keep clear.

Three of the basic rules of the road for sailing also apply to racing.

These rules are:
* When boats approach each other on opposite tacks (one starboard tack and one port tack), the boat on port tack shall keep clear of the boat on starboard tack (Racing Rule 10). The port-tack boat keeps clear, if the starboard-tack boat does not have to change course to avoid a collision. (Just like driving an automobile you yield to the right – yield to the boat whose boom is on its starboard (right) side)

* When boats are on the same tack and overlap each other, the windward boat shall keep clear of the leeward boat (Racing Rule 11). If your boom is on the side toward the other boat, you are the windward boat. Don’t run your boom into another boat.

* When boats are on the same tack and don’t overlap each other, a boat that is overtaking from behind shall keep clear of the boat that is clear ahead (Racing Rule 12). The overtaking boat must change course to avoid running into the back of the other boat. If the boat from behind continues to overtake the other boat and they become overlapped then the windward-leeward rule (Racing Rule 11) applies – the windward boat must keep clear of the leeward boat. If you are overlapped and your boom is pointing toward the side the boat is overtaking you, you must keep clear.
