Sailorwest is entirely correct. Your time on board a ship as a MESO will be very busy. You will sail lots and when your particular ship isn't sailing, be prepared to perhaps join another ship that is because they are likely short MESOs as well, although this is mostly at the B-ticket (Engineering Officer-of-the-Watch) level.
earlier quote:
"In relation for to one of my other questions, after you do MESO QL1, QL2 is OJT experience (4-6 months). It says that OJT can be tailored around the member's schedule. Would I be able to, for example, do four months (120 days) over 60 weekends on the MCDVs? (The idea behind this is I'm thinking of doing a degree in Mechanical Engineering and thought that being a MESO would be the most relevant naval reserves occupation but this obviously puts strain on time especially because the University of Victoria has a mandatory Co-op program.)"
Kratz's advice here is sound. Your 4-6 months of OJT being "tailored" around an individual's schedule has limits. Weekends will be a no-go, in addition to the cost that Kratz outlined. Weekends are one of the few periods when the ship ISN'T sailing - it will likely be alongside home or foreign port - either way, no training is going on. You need 4-6 months of sea-time (mostly) to gain experience conducting drills and whatnot. The number of requirements to complete combined with the number of hours you must stand (sea going in addition to harbour-watch hours - the exact number escapes me) requires you to spend much time at sea. And it really does take 4-6 months - this is the barrier for Class A (part-time) MESOs who simply cannot get that much time off from their civilian employers. So, a schedule "tailored" around your schedule implies blocks of time - weeks (preferably months) at a time.
