Welcome to the boards
As Pblais has already said, you will found out about stuff that you never know existed and of course never knew you really needed.
Just another tip, get used to the term 'Boat Units'
This is a very handy term when trying to justify to the Admiral, why you really really need this gadget...See Honey, its only 10 Boat Units...
This is the start of a neverending journey.
