Theory
Reference: Chapter 13 pages 80 - 83
- P-Effect
- Majority of boats will turn towards port because they have right hand propellers
- Port - Right (clockwise)
- Starboard - Left (counter clockwise)
- Right - pushes stern out right, causing boat to go left
- negligible with small outboard, notices more with inboard engines
- Wake
- Make note of your wake at various speeds
- why?
- so you are not causing damage to other boats when going into/out of harbour
- so when you pass canoes / kayaks you don't swamp them
- You are responsible for your wake!
- Discuss effects of wind and current
Activity
- Two complete circles port and starboard, forward and reverse (low speed, tiller only)
- Make note of wakes
- Make note of turning radius (both forward and reverse)
- Make note of which way to turn the tiller (banana theory)
- Notice which circle is tighter (clockwise indicates left)
- Try forward circles at full speed, notice greater diameter an heel
- Stopping distance, get boat to full speed then stop engine
- Note how long it takes for boat to come to a complete stop
- How can we make the boat stop faster (try using reverse to stop boat)
- Reverse in straight line
- Approaching mark - approach mark with no speed when mark is abeam
- safe way to practice coming along side
