all I can present is how I did it. My personal experience.
In order to sit for the U.S.C.G Captains License ( merchant marine
capt ) I had to have 720 days at sea documented time.
It took me five years working as a sailing, and motor
vessel instructor, and taking out charters.
I renewed it every five years thru sea time and or testing. On the fifth issue The U.S.C.G. upgraded my license it to 500 tons ( limited to near coastal ). That was an adendum ( see revers) on the back of the 100 ton certificate.
I had all of my paper work in order, and my long list of the vessels that I had sailed as " Crew", I could not list them as captain
Name of the vessel, type, CF or Documentaiion number, length of the vessel and area sailed.
Also, I had the endorsement of the Newport
Sailing Club, and my own log book. They had all of my time on the computer .
Actual event at the U.S.C.G. testing office. The U.S.C.G. is a United States of America military organization. I was a veteran ( U.S Naval air-Vietnam) and understood military bearing. And, being 100% organized.
A showed up at the U.S.C.G testing office Long Beach, Calif. groomed, clean shaven, dressed in pressed pants and a shirt and nice sweater. I reported 15 minutes early just like you do when relieving a watch.
I was standing there, when a burly, unshaven , hair amess, and dirty clothes, applicant butted in line ahead of me. I kept my mouth shut.
The USCG Lt. asked him what he needed. He was there to take his captains test. The Lt took is paper work and looked up something in his own paperworkd and said "you are late ". Well the applicant made some excuse, that did not work.
the LT handed the applicant back his paper work and told him to call on the phone
, and make another appointment.
Now , I walked up, the LT looked over my paper work, that was organized and had all of the required documentation, and said,
" You want to go for your 100 ton ? "
" Yes sir, I would. "
The testing began in another room. There are several different sections to the exam. You take the first section, 90% to pass. If you fail any section, you stop and return the next day. I just kept on going. l Most of the sections required a 90%, some were 70%. It took me all day to go through all of those sections, which do have time limits. If you fail the same section again, then you went home and studied up and could return in 30 days.
The next day, I came back for the Navigation
part. 90% required to pass.
That took 3 hours. And you could not be more than a lead pencil point off.
Passed, and the Testing Office typed up my 1st issue of the 100 ton lic.
What really helped was not only my 5 yeas of experience and attaining those 720 days sea time, was attending a U.S.C.G License Preparitory Class.
Well, I thought I was pretty knowledgeable, but I learned so much in that class that was taught in an interesting and simple way, that I actually passed on that easy to learn knowledge to my students.
So, the above is actual fact of how I attained my license and continued on for 25 years.
It was necessary for me to work for compensation to have the U.S.C.G Captains License. All seven of our instructors went thru the same prep class and all passed the exams. We just happened to take them on different days.
As to the six pack, I have no idea as to if the test is the same as the 100 ton, but i took the testing very seriously, but also was excited about learning
every thing that I could to be a professional capt, and impart that knowledge to our member
Hope this helps.
