Re: ASA Coastal Nav Exam - HELP

I learned it (and practice it) as JackDale describes. Advance the initial LOP based on time and course traveled between the 2 LOPs.

Re: ASA Coastal Nav Exam - HELP

I used the Tools in OpenCPN and Elements to show my plotting. That special purpose buoy is not shown in this chart, so I used its lat and long



Be careful with labelling as well. In Sail Canada (CYA) plotting and labeling is worth marks. Is that also true in ASA?

I have just done a cross over from Sail Canada to ASA. I have to do 214 (catamaran) separately, so I am going to Sausalito next week. So I am also studying. Any advise would be gratefully accepted.

Re: ASA Coastal Nav Exam - HELP

Thanks jackdale!

While very similar to what I did, it was not the same. I forget this stuff!

Based on your notes, here is my solution to the problem;
Step 0: Plot the intended course & danger bearing;
Step 1: Establish LOP on known object;

Step 2; Maintain course and heading for specific time, and establish second LOP on the same object;

Step 3; Advance LOP from first bearing by the distance traveled using 60 * D = S T;

Step 4: Running Fix is where the two lines cross. Plot Course Made Good (CMG);

Re: ASA Coastal Nav Exam - HELP

Next steps:

- plot original DR position anticipated at 1620
- compare 1620 running fix to 1620 DR and calculate set and drift
- apply set and drift to DR course out of 1620 running fix or, better still, recommend course change out of 1620 running fix to compensate for set/drift and still avoid being run up on the lee shore of Pt Judith Neck.

Your plotting looks good. Check the labeling. I forgot to to label the course line. It should also have one arrow on it.

C 354_____>_________
S 4.0


The CMG line should have two arrows.

You need a departure time from the buoy to get a DR.

Exactly.

I was also taught to put hash marks in a danger bearing line and label as either NLT or NMT

Re: ASA Coastal Nav Exam - HELP

The course line should have the course in true on top and the speed (from the knotmeter) on the bottom.

I pulled up a copy of the 1210tr chart from Ocean Graphics;http://www.oceangrafix.com/chart/zoom?chart=1210TR .

Not sure.... IIRC, ASA only looked at the fill_in_the_dots answer sheet.

I'd love to help, but I'm having enough trouble with one hull. Good luck on the test!
