RYA LEVEL 1 & 2 Theory ...

Rigging A Boat

  • Make sure your boat is pointing into the wind.
    Otherwise it will try and sail across the land causing damage the hull and anything else in its way. If its not pointing into the wind on a double hander, when pulling up the sail you will rip it on the spreaders.

    launching & Recovery

    • Handling boats ashore

    Most the damage that happens to boats occurs while the boat is on the shore or being taken too or from the water. A boat must fit the trolley it is on. It must be straight on the trolley and secured to the trolley to prevent it accidentally falling off.
    Other hazards to boats on shore are overhead and seabed cables, As well as leaving your trolley above the line where the tide will come into.

    • Returning to the shore

    • Storing Equipment

    The stowage of all the boats equipment is very important. First of all you should to a basic check for and worn out equipment and either mend it or report it to an apropiate person. This is so it wont spoil the next time the boat is used.
    Sails should be dried if wet then stored in a dry warm place so they don?t grow mould. The average sail costs £200 +. Sails need to be rolled.

    Single hander sails on a freestanding mast are normally just wound round and round the mast

    Single hander sail wrapped up

    Double handers have two sails the jib and the main sail.

    The jib has wire sewn into the sail along the leading edge.
    Starting at the top of the sail, coil the jib along the wire until you end up with a tube then roll the jib along the tube so that the ropes stick out the end, then secure the ropes round the cloth to make into a neat bundle.

    The jib wrapped up

    The main sail is normally wrapped round the boom in training boats. The main sail isn't a flat triangle of cloth, it is a 3D curve, therefore it won't just wrap round the boom. You have to take a tuck up to the first batten then roll it. Securing it into place with the main sheet.

    Sailing Techniques & Manoeuvres
    • Stopping
    A boat has no 'Breaks'. To stop the boat moving forward you have to de-power it. You do this by 'loosing' the wind out of the sails. The way to do this is to make sure the boat is pointing across the wind then letting go of all the sails. This is called a 'Basic hove too position.' To start the boat moving again it is simply a case of pulling in the sails.

    • Getting out of irons
    When a boat is pointing in the wind the sails wont fill and will flap around above your head, we call this 'In Irons' or Head to wind. To start the boat sailing again we need to point it away from the wind. On a double hander we can hold the jib out one side and the boat will turn. In a single hander which has no jib we push the main sail out away from you then pull the tiller towards you. You may hear this called the 'push push pull pull ' technique.
    • The Five essentials

    For a boat to sail as fast as it is able too the sailor must be applying the five essentials. The five essentials are

    1. Sail setting
    2. Balance
    3. Trim
    4. Centreboard
    5. Course made good

    Sail setting
    This is as it sounds. If your sails aren't pulled in and are flapping then they are not driving the boat forward so you aren't sailing as fast as possible

    Balance


    This is the side to side movement of the boat. A boat is designed to be sailed with the mast pointing upwards like the middle picture. This is achieved by moving your weight around inside the boat. In the worst case of the boat being unbalanced the boat will capsize.

    Trim
    Trim is the back and front movement of the boat. If you sit right at the back of your boat the nose will lift up but the back will drag along in the water, likewise if you sit too far forward then the front will nosedive and dig in and slow you down. You need to sit as near to the centreboard as possible

    Centreboard
    The centreboard is there to stop the boat getting blown sideways. So when the boat is sailing towards the wind the wind has the greatest sideways force so we need the centreboard all the way down. When we go across the wind we only have 1/2 the sideways force so we only need 1/2 the centreboard down. When we go downwind the wind is behind you pushing you forward so you don?t need it to stop you going sideways so you can lift it all the way up.

    Course Made Good
    Basically means sailing the quickest route from A to B. Normally a straight line unless going to windward where you do 'zigzags'.

    • Man Over Board (MOB)

    This is one of the most testing skills of sailing. Proberlly because it is most likely to happen when it is really windy.

    Sailing Theory and Background
    • Rules of the Road - RIGHTS OF WAY
    • Rule 1 - Avoid Collisions

    Despite the many rules defined in the "International Regulations for Prevention of Collisions at sea" there will be time when you find yourself on a collision course with another boat which is not giving way as it should. 'Take early evasive action to avoid damage or injury which might result from a collision'.

    • Rule 2 - Power Gives Way to Sail

    All power craft are supposed to give way to boats under sail, and most do. However, some power craft are restricted in their ability to manoeuvre, and you should show courtesy to the power craft by allowing them sea room whenever possible.

    • Rule 3 - Small Boats Give way to Large Boats

    The larger the large boat, the more true this is! For example, the crew of an oil tanker may not see a small sailing dinghy in its path. Even if sighted, the tanker would take a considerable time to turn or stop. It may be in a narrow deep water channel and unable to take avoiding action without running aground. The rules (and common sense) says keep clear.

    • Rule 4 - Port gives way to Starboard

    A sailing boat is on a PORT TACK when the wind blows over the LEFT side of the boat (looking forward) causing the sails to set on the RIGHT side. The opposite is called a STARBOARD TACK. You may find it helpful to remember this expression

    There's some red port left over

    Red is the colour associated with the port side (channel marks, navigation lights etc.) The drink port is also red in colour. "Left over" refers to the wind blowing over the left side of the boat.

    • Rule 5 - Windward gives way to Leeward

    When two boats are on the same tack (both on port or both on starboard) the one nearest the source of wind must give way to the one furthest away.

    • Rule 6 - Overtaking boat keeps clear

    This rule belongs to racing rules, but as courtesy, keep clear when overtaking a slower boat

    • Rule 7 - Still Avoid Collisions

    Not everyone may know the rules governing the rights of way, although they should! Allow for ignorance, inexperienced and downright rudeness (sadly this sometimes happens) and leave yourself an escape route. Aim for the gap which is opening, rather than the one which is closing!

    • Points of Sail

    • Buoyage

    If you are sailing in coastal waters you are likely to see many different floating marks and coloured posts. As a dinghy sailor you only need to know about a few of them so as to make an educated guess where other bigger craft are going.

    Red cans. These are port markers and mark the left hand side of the deep channel going into a port

    Green cones. Mark the starboard side of the channel going into a port.

    Yellow buoys are generally racing marks and sometimes have a cross on them

    Meteorology

    It is important to get a forecast before you go out in a boat so you know what to expect while you are out there. It?s the difference between an enjoyable cruise or an expensive salvage claim, between getting a suntan or being freezing cold and wet.

    Where can we get a weather forecast from ?

    • Radio

    Radio 4 broadcasts the shipping report 4 times a day and gale warnings are broadcast as soon as they are received. Inshore weather reports can be heard twice a day on Radio 3, and local radio stations are probally the most useful for dinghy sailors.

    • Television

    Most ITV and BBC channels provide weather reports around news time. There is also Navtex which is available to everyone who has teletex on their TV. A general overall picture can be seen as well as specific areas.

    • Fax / phone

    Forecasts and up to date weather reports are available for all sea areas by phoning either marine call or weather fax. These reports are very detailed and accurate but all calls cost 50p a minute and the reports on the phone are read out at normal speed and it is very difficult to write down all the details
    Two separate services are provided on these lines, you can either get a 24 hour one or a 2-5 day report. These maps are drawn from the data collected from over 60 weather stations around the UK.
    In edition to this anyone with a mobile can get the weather via a text message to their handset.

    • Internet

    There are hundreds of sites that provide weather. The main one is the met office at Bracknell, where up to date reports and charts are provided free for anyone with the right equipment to download.

    • Newspaper

    All national papers carry weather charts but these are normally out of date as they were printed at least 24 hours ago.

    • Harbour master / coastguard

    The harbour masters office will have a board outside where they will post the latest weather report. If you have a VHF radio you can call up the coastguard and ask for a weather report but they do broadcast them at regular intervals and wont be amused if you ask for a report 5 mins after they have just given one.

    Capsize Recovery

    Why we capsize

    • Boat is unbalanced
    • Uncontrolled Gybing
    • Broaches when the spinnaker is set on a broad reach
    • Squall catching the boat
    • Gust catching the boat with the crew unaware
    • Heavy rolling downwind
    • Crew does not get in quickly enough after a gust
    • Over sheeted during a gust
    • Crew comes in too late from the trapeze

    Righting Technique

    Stage 1

      • Crew and helm swim to the stern to check the rudder is secure and that all members of the boat are accounted for.
      • Helm finds the mainsheet and uses it as a lifeline to swim around the boat to the centreboard.
      • Crew swims along inside the boat to the centreboard case

    Stage 2

      • Crew checks the centreboard is fully down

    Stage 3

      • Crew finds the top jibsheet and throws it over to the helmsman who is warned of it coming.

    Stage 4

      • Crew lies in the water by the hull facing forwards above the side deck making sure not to hang on.

    Stage 5

      • Helmsman lies back straight in the water with his feet on the bottom of the baot and pulls on the jibsheet.
      • Alternatively the helmsman climbs onto the centreboard keeping his weight as close to the hull as possible to avoid breaking the board.
      • Once there he then hauls on the jib sheet to right the dinghy and at the same time "scoops" up the crew.

    Stage 6

      • With the dinghy facing into the wind the crew helps the helmsman aboard.

    Things to Remember

      • Make sure that if you capsize to windward be careful when righting the boat because it could flip the other way.
      • If you can rotate the bow head to wind
      • Communication is important to ensure that stages are done correctly
      • The dinghy will be easier to right if the person hauling up keeps their legs and back straight
