Course contents

Course Heading 2013/14 :

1.- Boat terminolgy :

      main components : hull - propulsion  system (sails-engine)- stearing system (rudder- stick-wheel)

1.1.- hull: types-equipments-masts . fixed rigging ("static"): shrouds-stays- barrens- set up-"winds"- bobstays. Mobile rigging : ("dynamic"): halyards

      -sheets- vang- hoist - masts and crosstrees

1.2.- Sail terminology : hoist-plank-base

1.3.- Sail types . spanker Marconi (bermoudian)-fore and aft sail- jib-spinnaker-genoas-gennaker -windsurf sail- classic rigging-modern rigging

1.4.- boat drift : bayonet-weighing

1.5.- rudder control : rudder effects on the boat (manouevre curve)

1.6.- boat masts : masthead-base- partners-step - crosstrees; functions;  boom- bowsprit

1.7.- boat equipments : characteristics of : blocks-bollards-cleats-hoist-winch

1.8.- Main knots : reef knot-lover's loop- Savoia- Mooring knot-flag knot- -fishermann's bend; characteristics

 

2.- Technical informations about the sail

2.1.- boat trim; definitions: fin-drift centre-sail centre

2.2.- boat stability : weight-shape-diaghrams

2.3.- trim : trend moving to the right/left- trend luffing r/l

2.4.- transverse trim

2.5.- longitudinal trim

2.6.- control by rudder

2.7.- control by mobile fin

 

3.- Practice informations

3.1. directions (diaghram) : bow directions (narrow/large bow); bearing directions (amidship- bearing- astern)

3.2.- wind effects against sails

3.3.- manouvering: windward-lee-side- ship's side r/l; to luff /to move to the r/l -tacking /turn

3.4.- Practice at sea : circuit ("stick")- triangle -tacking (zigzag)

4.- Approaches avoidance at sea

4.1.- precedences for sailboat and motorboat - special events

4.2.- special signs : daily-nightly

4.3.- collision danger : avoidance method

4.4.- the "Safe Navigation" poetry

5.- Weather  Forecast for boats

5.1.- Atmosphere constitution (diaghram of Temperature/natural effects); weather  parametres and changes; Temperature-Pressure-Umidity; measure

       instruments

5.2..- isobars; high/low pressure areas; barometric gradient

5.3.- Wind; Buy-Ballot Law; wind arising; day and night

5.4.- Relative wind; breezes; gradient winds

5.5.- general flow of the air on the earth

5.6.- wind measure- instruments

5.7.- characteristics of winds into the Mediterranea basin: special notices for "italian"winds (Adriatic-Jonian, Tyrrenian. Ligurian Sea)

5.8.- wind effects on the sails

5.9.- Sea State (waves and scales : Beaufort-Douglas)- fetch- "dead/alive" sea

5.10.- suggests  due to presence of sea /earth wind

5.11.- Pressure configurations : H/L pressure zones-air-pockets- promontory-slope-cold/hot forehaead -occluded forehead

5.12 : clouds : types-categories- constitution; the "cumulus-nymbus"analysis

5.13.- stormyweather  : risks; tornado danger, marine  tornado; the fog (how to defeat on the boat)

5.14.- short data  about marine currents and tidal

 

6.- Safety and Rescue onboard

6.1.- Check of safety equipments onboard

6.2.- Man over Board (MOB) : method and manouvres

6.3.- towing the boat

6.4.- Upsetting of the boat;: types, actions for rescue

6.5.- straightening the boat

6.6.- Methods -technics

6.7.- Notices about stranding-getting afloat-fire, leak

6.8.- Sailor dresses (characteristics)-safety equipments (individual life-buoy; life-jacket)

 

7.- sport practrice

7.1.- Circuit training-"stations" concepts

7.2.- body positions onboard

7.3.- gymnic exercises (30 descriptions)
