1. To use a GPS receiver to produce a speed curve you should:
a) Produce a "measured mile" by plotting two WPTs 1 mile apart
b) Prepare a speed curve by using a constant RPM and running the measured mile both ways while recording the time taken.
c) Record Speed each way S=60 X D)/t (S==knots, D=dist in nautical miles and t=time in minutes)
d) All of the above are necessary
Answer:

2.The GPS can be used to adjust trim tabs or stern-drive trim angles by:
a) Recording COG while adjusting the trim tabs
b) Recording the SOG while adjusting the trim tabs
c) Recording the SOG while changing the RPM of the engine
d) Adjusting the RPM while recording the COG
Answer:

3. By checking the boat speed at fixed RPM settings one can:
a) Determine engine efficiency
b) Determine engine efficiency only if previous records are available for comparison
c) Determine the speed of the current
d) None of the above
Answer:

4. The speed of current in a river can be calculated by:
a) Checking the speed of a carefully calibrated knotmeter
b) Checking the speed as indicated by the GPS receiver
c) By comparing the speed as indicated by a calibrated knotmeter with the speed as indicated by the GPS
d) None of the above
Answer:

5. Your compass can be checked for deviation by:
a) Comparing the magnetic heading given by the GPS with the compass heading
b) By comparing the true heading given by the GPS with the compass heading
c) By looking at the variation as given by the compass rose
d) None of these methods are suitable
Answer:

6. Proper sail trim can be selected by:
a) Changing headings for each different sail trimming adjustment
b) Maintaining a constant heading while adjusting sail trim for optimum speed
c) By looking at the variation as given by the compass rose
d) Any of these methods are suitable
e) None of these methods are suitable
Answer:

7. When sailing in tidal currents staying on-course can be achieved by:
a) Comparing the Course Made Good (CMG) with the cross-track error
b) Adjusting for best SOG
c) Adjusting for zero XTE
d) None of these will help
Answer:

8. By logging the actual sailboat's leeway in slack water (no current) under various points of sail a detailed picture of the boat's performance can be achieved:
a) Noting the measured leeway when sailing in tidal currents
b) Only if the strength of wind is known
c) Only if the conditions in a) and b) are considered
d) None of the above methods
Answer:

9. The GPS computer can help determine the optimal time to tack, in order to reach a given goal by:
a) Tacking when the WPT (goal) bears less than 45 deg. relative to the current.
b) Tacking when the WPT bears more than 45 deg. relative to the current
c) Tacking when the WPT bears more than 45 deg. relative to the apparent wind.
d) None of the above.
Answer:

10. The difference between heading and COG to a WPT is:
a) The cross-track error
b) The leeway or windage
c) How far the vessel is from the intended track.
d) The VMG of your vessel.
Answer:

11. The VMG to a certain mark on a sailing vessel is:
a) Good if the actual SOG is higher.
b) May even be a negative value even though the SOG is increasing
c) Good if the speed through the water is increasing
d) All of the above are correct.
Answer:

12. When sailing towards a specific destination, the object is to:
a) Attain the maximum value of VMG.
b) Attain the maximum value for speed through the water.
c) Attain the maximum value of SOG.
d) None of the above.
Answer:

13. Which of the following is true about the value of GPS receivers.
a) GPS receivers do not work well in wet, rainy conditions
b) GPS receiver may have an error called deviation which is different on each heading
c) GPS receivers may have an error called variation which is due to the electrical and magnetic effects of the ship.
d) GPS receivers are basically not affected by fog.
