I'm going to disagree with this for the sake of future OCs who might be reading and might get the impression that moboards should be a breeze. A lot of people struggle with moboards; I've seen some very bright people struggle with them and some not-so-bright people get them very easily. About 20% of a class (or more!) will fail their NOS exam and have to retake it. Moboards might not be hard, but learning them at the same time as navigation and ORLP is not easy.
When I attended, the only people who failed moboards were SWOs with borderline pre-Navy credentials. It's not hard to draw a few straight lines using a ruler and measure the distance of the resultant vector with a compass and compare it to the scale. Also, IIRC the instructions on how to do it are ON THE MOBOARD PAPER.
And thanks to this invention called RADAR, you can be assured that skillset is about as useful as being able to pat your head while rubbing your belly.
I had to admit that it was odd how SWO centric the whole program was when a minority of the OCs are going to be SWOs. You'd hear things like "Naval officer first" (as if moboards are more officer-like) or "Hey aviators, If you're ever the CO of a big deck you'll need this!" or even "Aviators? You mean future SWOs!" Don't get me wrong, I really liked most of the instructors and class Os from my time there, but there were just two aviators working there if I recall, and only one was an instructor. Some aviation stuff came up in engineering and weapons, and we had to aircraft and their weapons for ORLP just the same as the surface and sub side of things. If you were going to tailor the program to the majority of OCs, it would have a much stronger aviation focus.
The impression I get from this site is that SWOs can't figure out their follow-on training or if they even want to keep it. It keeps bouncing around from SWOS after commissioning to SWOS before the pin. So they do a lot of SWO-centric stuff because until very recently, that was the extent of their formal training before they got thrown to the wolves.
Also, not every class makeup is the same. We had more SWOs/sub/suppos than aviators.
And if someone thinks that an aviator is going to remember doing moboards for 4 days after 16+ YCS, he's smoking some goooood crack. I caught a bit of crap for not knowing what a bollard was when practicing unassisted landings in a trainer, and that was less than 2 years out of OCS seamanship, so you can see how well that gets retained.
