Advanced Questions: 

1A.  You are planning to charter a sailboat.  The boat has the following specifications: 

 Using the calculators in this website you predict:   

        

The boat slow in light winds but  is very stable.
Stability is NOT predicted by the Capsize Screening Formula
       but the boat is fast in light winds.
Stability is predicted by the Capsize Screening Formula but the boat is slow in light winds.
It has a theoretical hull speed of over 8 knots.

2A.  What is the estimated Angle of Ultimate Stability for this boat: 

  117 degrees
  127 degrees
  136 degrees
  142 degrees
  149 degrees

3A.  You are off shore in a sailboat in a Strong Gale, what would you consider to be the most valuable ?

  To be in a boat which has shown to be stable by the screening stability equation.
  To be in a boat with a high angle ( greater than 140 degrees ) of vanishing stability.
  To be in a boat with an experienced crew and the avoidance of extreme breaking waves.

4A.  Your sailboat is in a storm with 28k winds.    Your jib's sail area is 250 sq feet.    You have a winch with a 5:1 gear ratio and a 4 inch diameter drum and a 10 inch winch handle.  What is the total force on the sail and the force on the winch handle needed to trim the sail ?          

  422.5 lbs. of force on the jib with a winch force of 17 lbs.
  845 lbs. of force on the jib with a winch force of 34 lbs.
  1690 lbs. of force on the jib with a winch force of 68 lbs.
  3380 lbs. of force on the jib with a winch force of 54 lbs.
  6760 lbs. of force on the jib with a winch force of  68 lbs.

5A.  The wind is starting to blow stronger and you are seeing frequent white caps with some spray.  The following statement is TRUE?

  All sailboats, no matter how large will require placement of a single reefing.
  The wind velocity is probably above 15 knots and one should consider reefing.
  The wind is not strong enough to consider reefing in sailboats larger that a dingy.
  The sailing conditions are perfect for the beginner learning to sail.

6A. Which statement is FALSE regarding changing sail shape ?

  Setting the Cunningham will depower and flatten the mainsail.
  Tightening the outhaul will depower and flatten the lower 1/3 of the mainsail.
  Tightening the boom vang will raise the back of the boom and let out the top of the mainsail.
  Tightening the backstay will straighten the luff (front edge) of the jib.
  Moving the fair lead forward will tighten the jib's leech as the jib's working sheet is trimmed.

7A. Which statement is TRUE regarding navigational aids in the United States ?

When going upriver or into port one should have red buoys on the port side of the boat.
When going south on the North Carolina intracoastal waterway, red daymarks should be on the starboard side of the boat.
  One may go between two buoys or daymarks of the same color.
  It is allowed to tie up to a buoy or daymark.
  Red buoys are called cans and have flat tops.
  Red daymarks have a triangle with an odd number.

8A. Which line adjustment will place a twist in the mainsail to compensate for higher winds aloft ?

  Tightening the boom vang
  Tightening the outhaul
  Loosening the backstay
  Loosening the boom vang
  Loosening the outhaul

9A.  The top of the jib is luffing, but the bottom tell-tales are streaming backward.  To trim the top portion of the sail you should:

Tighten the jib's halyard and adjust the jib's sheet
Tighten the boom vang and adjust the jib's sheet
Move the fair lead forward and adjust the jib's sheet
Loosen the jib's sheet and adjust the jib's sheet
Move the fair lead aft and adjust the jib's sheet

10A.  All of the following are used to adjust the Jib's shape and trim EXCEPT :

  Jib's Sheet
  Jib's Halyard
  Backstay
  Fair Lead
  Boom Vang

11A.  You are sailing at 5 knots across a strait.   You encounter a 3 knot head-current develops which is 30 deg off your bow   How many degrees towards the current (Course to Steer) do you have to change your course to maintain your Course to Make Good. 

  8 degrees 
  12 degrees 
  15 degrees 
  17.5 degrees 
  20.5 degrees 

12A  Your eye level is 12 feet above the water.  At what distance, on a clear night, will you see a 76 foot lighthouse (assume ample lumificaton)?   

  10 nautical miles
  11 nautical miles
  12 nautical miles
  13 nautical miles
  14 nautical miles

13A  Which of the following will let out the main with the least change in sail shape ?   

  Traveler
  Mainsail's Sheet
  Boom Vang
  Outhaul
  Boom Topping Lift

14A   You have a nautical chart from the US west coast.  The soundings on the chart are most commonly measured using:
(Always know the units and significance of the soundings on any nautical chart you use !!)

  The lowest possible water level.
  The average of the lower tide levels (the lowest of the two daily tides).
  The average depth of all the low tide levels.
  The mean water level.
  The average of the all the high tide levels.
  The average of the highest tide level (the highest of the two daily tides).

15A  The telltale on the leeward side of the sail is luffing, the telltale on the windward side is streaming straight back.  To trim the sail you should do the following:

Sheet in the Jib.
Move the fairlead forward.
Turn the boat towards the wind.
Move the fair lead backward.
