SADDLEBACK COLLEGE
ADV. SAILING/CRUISING, MST. 214B
Hughston/ Howe, Spring 2008 Name
SECOND MIDTERM
[All questions worth 2 pts. unless valued otherwise]
1. What underlying principle normally ensures that an anchor won't break free of the bottom?
[Hints: If you do x the anchor will dig in; if you do y it will break free; proper scope is not an underlying principle.]
Horizontal pull
2. What is the anchor rode?
The rope and chain that connects to your anchor.
3. How would you get your anchor loose from a snag in rocks?
Jiggle it loose.
4. [6 pts.] Name, sketch, and describe the characteristics of two types of anchors.
Plow anchor; heavy, good all round in different kinds of bottom conditions including kelp.
Danforth type (lightweight): half the weight of a plow, very good in sand or mud but not so good in hard bottom, rocky or kelpie bottom conditions.
5. In a meeting (head on) situation between two sailboats under power, what is the procedure?
Both boats keep to the right and pass port to port.
6. What must a stand on vessel do when on a collision course with another boat?
Maintain course and speed until collision is imminent.
7. A sailboat has the right of way over power in most cases. Give four exceptions to this.
1. towing or fishing 2. overtaking
3. large vessel in tight quarters 4. minesweeper sweeping for mines
8. You are approaching an unfamiliar harbor and see red and green flashing lights ahead. How should you enter the harbor?
Keep the red one on the right and /or the green one on the left.
9. [3 pts.] What do the following symbols on a navigational chart mean?
1. Teardrop shape: 2. Diamond shape: 3. Star/asterisk: *
Beacon buoy boat eating rock
10. [4 pts.] You are on a starboard beam reach and
another sailing vessel to your left
is on a collision course with you.
Draw a picture showing who has the
right of way and why?
[wind from the top of page]
11. How would you interpret the min. depth of water in feet for anchoring in a cove if the tide table predicted a low tide of +2ft and the chart showed a depth of 10 ft? (ie. how low can it go?)
10 plus 2 equals 12
12. What is meant by "twist" in a sail?
Top of the sail is trimmed out more than the bottom; top luffs more than the bottom.
13. Under what conditions could twisting a sail be useful? How so?
Spilling wind from the top of the sail to reduce heel during strong wind conditions.
14. What makes an intentional gybe safer than an accidental gybe?
Control.
15. If you depart Dana Harbor for Catalina at a speed of 5.5 knots, how far will you have gone in two hours?
5.5 times 2 equals 11
16. [3 pts.] What are the three most important characteristics that make a working jib [or storm jib] more appropriate than a Genoa for stronger winds?
Smaller size, heavier material, flatter shape.
17. How do you avoid tangling your anchor with the chain when anchoring?
Be sure you are going backwards when paying out bow rode (or forward for stern).
18. When is a boomvang important?
Sailing downwind.
19. What will be the effect on weather helm if you move weight forward in your boat?
Increase. Same as moving CE aft.
20. [4 pts.] Give two effects (results) of reefing the main as each pertain to helm balance and control.
[First give the effect and then state how it pertains to helm]
What reefing the main does Helm balance and control
a. moves CE forward reduces weather helm increasing control
b. reduces heel reduces weather helm increasing control
21. Whats the significance of a red bouy with letters painted on it?
Danger buoy; the letters signify the danger.
22. Whats the difference between heaving to and lying ahull?
Heaving to is parking the boat with the sails up; lying a'hull the sails are down.
23. What happens when temperature drops to the dew point?
Condensation.
24. Which of the heavy weather survival techniques are you actually sailing?
There are four techniques; when running you are sailing.
25. What does a wind shift backing to the south [SE to SW locally] predict weatherwise?
Cold wet storm approaching.
26. What very dry weather condition can result in dense fog and how does it happen?
Santa Ana is dry because of high pressure. At the end of the Santana the pressure drops and the humidity rises to the dewpoint creating fog.
27. What use can you think of for a rolling hitch to get you out of trouble?
Taking the load off of a jammed line to get it unjammed. (changing lead position, anchor rode position, etc.)
28. How does moving the jib lead forward affect the twist of the jib?
Reduces twist by pulling down on the clew to flatten the leech.
29-32. [2 pts.each] Tie any 4 of the following knots:
double bowline rolling hitch flying bowline anchor bend
double sheet bend clove hitch flying sheetbend
Extra credit [4 pts.] tie a double flying sheet bend without coaching. |

These are the answers to the 2nd midterm.
You won't have your actual results until the night of the final unless you let me know how you want to pick it up early.
I will post a crude copy of this in case anybody has trouble downloading the file. |

Study guide for those who are making up the 2nd Midterm exam on Monday.
Since those on the cruise are going over many of the practical aspects included on the written midterm, this discussion is offered so that you will have a better idea of what to study.
Anchoring:
More detail based on our discussions in class; lots of questions. Read your notes carefully.
Rules of the Road:
Be prepared to draw diagrams showing sailboats on collision course and who has the right of way.
Aids to navigation; chart symbols and chart reading:
Depth determination based on the tide table readings, significance of danger buoys with letters painted on them, other chart symbols.
Sail shape, twist, CE/CLR, onboard sailing equipment (gizmos).
Relationship of temperature, pressure, and relative humidity in weather observations and predictions.
Examples of local weather systems -- page in class syllabus.
Heavy weather sailing:
Run; heave to; lie a'hull; sea anchor.
Don't forget to study the knot tying links.
Key points!
The key to breaking an anchor loose is not force.
The key to gybing is control.
The key to an anchor digging in: horizontal pull versus vertical for breaking loose.
The key to reducing weather helm is location of CE and heeling angle.
The key to storm sails is their small size, flat shape and heavy cloth material. |

As I was preparing for a class tonight I happened to look at the calendar and noticed that there is no class tonight.
I might expect there would be others of you who make the same mistake. We switched the schedule because of a number of factors including: its the day after Easter and some have vacations this week, and that was the only way to have the schedule come out right at the end.
In any event, this will alert some of you and for the rest, I will meet you down there tonight to let you know. :-) |

West Marine / Port Supply Discount Notice No. 2
I have constructed the new discount flyer with everyone's name on it to comply with West Marine's request, and they have approved it. If you want one before next class meeting, email me. I can arrange for you to pick it up from me, from Mark Howe, or at the College.

West Marine / Port Supply Discount Notice
Earlier I posted a flyer and handed the same out at class - a flyer that entitles you to wholesale pricing courtesy of our friends at West Marine. I have had to delete this flyer from the board and change the procedure at West Marine's request. The reason is that someone got alarmed at West Marine when they learned, via a purchaser, that this flyer could be downloaded, apparently for anyone to use. Here is how to make it work now:
1. You must use an original flyer with my original signature, no photocopies or computer printouts. I think that means you must hang on to the one you WILL get if you plan to use it more than once.
2. Ian tells me they will ask for your ID and your name must be on the flyer - that is the new one that I WILL hand to you.
3. It has to be you doing the buying, and not your friends and relatives.
4. This is only good now in Dana Point (2 stores) and Newport Beach.
5. I will have new flyers that comply with West Marine's request at the next class meeting, and those will have all of your names on them. Use the one you get at the next class meeting to make your purchases.
West Marine and Port Supply must be pouring a lot of money into Iraq because I can see how they might be concerned about giving up a few dollars to the odd purchaser from Dubai who found the flyer I posted, and is using it to outfit his Dhow for the local beer can races in the Gulf. |
