In 2008 Scott Fratcher sat for his MEC3 marine engineer exams. He quickly
realized that even with 20 years in the field experience and doing his
engineering part in setting the "Round the world speedboat"
record the algebra portion of the exam was a killer!
What was needed was an alternative method of answering the exam questions
that did not revolve around algebra, but still answered the exam questions.
Scott found almost every question could be answered through
and a few specialty methods developed just for the tests.
Using these techniques Scott Fratcher finished his two hour exam in
under 45 minutes being the first candidate to leave the marine exam
room. Using these techniques Scott Fratcher scored 95% on his exam when
he only needed 60% for a passing score.
Scott put the systems used to pass the marine engineer exam together
into a new book that has helped engineers just like you to pass their
exams first time!
Scott Fratcher also covers how to get your first job and getting through
the STCW courses.
The questions listed here are of a general nature. They come from classes,
study groups, Internet searches and just about any other place where
a student can scrape together engineers test questions.
It should be noted that each test is different and each test is written
by a different examiner. The test is written from the syllabus and this
means anything could be asked in a test.
Still you should have a pretty good idea how to solve each of these
problems as they are straight out of the syllabus.
Remember to look at each question and in your practice answer-
make sure you answered the question and
found the trap.
Of course not every question has a trap, but most have at least one.
Remember these questions can be worked out as a group. Once you have
worked out a problem change the numbers and values just a bit and work
the problem again. Compare each others answers till you have a clear
method of arriving at the same answers.

I found your info online and was hoping that with all your expertise
you could help me, I am also downloading your book
I was wondering if you could help me with the following.
I am a New Zealander currently employed as Chief Engineer on a big
yacht. I am going through the process of gaining my MCA Y4 chief engineers
ticket. From what I have gathered from others my Y4 ticket will not
be recognized outside Europe.
I was talking to another Chief Engineer last week and he was going
through the same issues and also looking into the possibility of doing
the NZ Engineering MEC3 ticket which he thought was not only
accepted but cross referenced to a relvent class with the MCA
What would your recommendations be considering that I will be coming
back to NZ to settle and would rather take the courses that make the
most sense for my future, although they need to be relevant to what
am doing over here at the same time ,
A ny ideas or help would be greatly appreciated.
I look forward to your response
Toby-This is a no brainier - Go to Auckland and take
the MEC3 course.
First being Kiwi you get reduced rates at class and can qualify for
Second and much more important, the MEC3 allows all the Y4 options
all types of ships (cargo, processing, tankers, coastal freighters,
and a heap of other options that a Y4 simply does not include.
Consider, your into yachts right now, and that's good. Me too, I'm
captain of charter cat in the Pacific, but what if you get tired of
yachts, or the yacht market crashes? With an MEC3 you still have a heap
of options in the Marine world, while the Y4 guys will have to sell
their limited services to whatever yachts are still hiring.
Third- If you keep climbing the ladder of engineer certificates you'll
max out at Y1 in the yacht world, but an MEC1 has another level above
MEC1. I think it's called "ships supervisor", so if you find
you enjoy the classes you can continue to study for a long time.
Forth- Once you leave Europe the term Y4 engineer gets a lot of blank
stares. "A what?" I often hear. Same with an MEC3 in the yacht
world, but an MEC3 is an official STCW qualification. In other words
it's the lowest world wide accepted engineer's license (certificate).
If an employer does not recognize MEC3 simply use the STCW term of,
... don't quote me but I think it's iii/3. That is a world wide accepted
Last piece of advice - While your back getting your MEC3 take your
Yachtmaster Ocean course also. It allows you to be mate on the same
boats you engineer on and opens other options for you. The cat I'm on
now needed an engineer more than a captain as it's a highly technical
vessel, but if I did not have my Yachtmaster Ocean the insurance company
would have balked.
Working in Alaska we always took the engineers that had a deck license
first. Just in case we lost a deck officer we could switch crew and
keep the boat going till we could find a new mate.
Tip-On your next ocean passage have the mate pull out his sextant
and take a set of running sun sights and a sunrise compass course. Keep
careful notes and save the calculations. Make sure you get the ships
stamp on the pages. This will qualify for the "Ocean Sights"
part of your Ocean ticket meaning you'll only have to take the five
day course and your Yachtmaster Offshore will be quickly upgraded to
Hope this helped.
Thanks for asking and downloading the engineer exam book.
