26092011(day skipper - day 1)

We had the day skipper today. Brett was our day tutor and his pronounce is different from Chris’s. Getting used to Chris’s voice, I felt slightly harder to understand than Chris’s class. We got a book ‘Day Skipper Theory’ published by coastguard and have to get it back to school.

- The sidelights on the port side are red, whereas they are green on the starboard side.(an unbroken light from right ahead to 22.5 degree abaft the beam on its respective side.)
- Most of cases, boats have the right way to starboard.
- Usually, the boat having the wind on starboard has the right way (stand-on), except they are heading same direction.
- bearing through an object (relative velocity - use something fixed on board (ex. Stanchion))
- speed (under 5 knots 200m from shore)
- safety distance 50m (at least)
- an overtaking vessel
- a crossing vessel
- blue peter(a flag for indicating there are divers below it) - within 200m from it, speed down under 5 knots
- the right hand rule(?)
- rescue chopper
- leaving ramp(?)
- The tropic of Cancer
- The tropic of Capricorn
- oscillate
- latitudes (every one of them has different length)
- longitudes (every one of them has the same length – 10800 nmile) we can use this(y-axis) on the chart when we measure the distance between two spot
- New Zealand is in far east ocean because the sun rises earliest ( east 177 something)
- Mercator’s chart (extend the actual size of a slice on the sphere into a rectangular piece)
- horizon – about 7.5 nmile
- VHF (Very High Frequency) international channel - #16
- magnetic polar (slightly different from the due polar and changes every year with 6~8 year period, so map changes every year. If vessels don’t go far away from shore, ignore)
- geomagnetic coordinate system
- magnetic field variation
- deviation
- magnetic compass has to be isolated from electric or magnetic facilities (otherwise it malfunctions)
- engulf
- magnetic variation 19 degree E (variation east compass least – minus 19 from what compass says
- outhaul
- fire
- communication & navigation
- safety
- weather
- barnacle (sea acorn) – prevent them by using toxic paint on hull(still legal)
- anchoring is the best way to avoid further disaster when vessels are on an emergency situation and helps the vessels turn into wave
- turn into wave (more stable) – head sea > beam sea > quarter sea
- when a vessel jump over the crest and rush to the wave hallow, it is likely to be yawning which is very dangerous (lost manoeuvrablity), broaching
- a rope on the stern
- when outboard immersed one time, it would lost power
- when anchoring the vessel, it is not good of the sides towards shore
- 2 minutes form ( where you intend to go? where you launch from? People on boat? When plan to be back? Give to trusted person – contact info of boat party, registration number, contact details for local authorities, boat colour, boat name, size, etc.)
- distress signal (flare ex> red flare parachute)
- sailing on a port tack – give way
- sailing on a starboard tack – has the right of way
- windward boat – give way
- leeward boat – has the right of way
- neap tides VS spring tides
- datum plane
- chart datum – lowest part when low tides
- charted depth – always immersed
- drying height – (?)
- no wet
- wind (from), tidal stream (to)
- ship speed and tidal stream speed are given draw vector lines and assume the distance and the time
- lulls, gusts
- lake – sometimes the weather changes in an hour
- 3 by 5, 5 by 5 ( the clarity of the sensibility of VHF or something)
- channel #16 (call up channel, emergency channel)
- the actual condition is prevailing (?)
- not a problem

It was really hard class for me to follow, because the things that we learned today were mostly in high school (or college) and they are quite hard to be understood with the second language. There were heaps stuffs(mostly details) but I didn’t get much of them. Bugger…With hindsight, I should have had sailing before.
