the responses will vary . . . based on individual's wants and desires.
like yourself, i'm former sailor and learned propulsion systems.
so, i'm a ME. myself, & several classmates, despised electrical engr classes - too many "loose electron" professors. probably should not have written the previous sentence, but studying electrical matters was not easy at the time for me. not easy to understand.
however, the more involved i became in project engineering roles, i began to learn and understand I/E details, needs, etc. i've enjoyed relations with the I/E engrs over the years.
perhaps this may help you. i, for one, need to understand the physical nature of objects and how they work, interact with other components, and their impacts. so, for me, ME was an easy choice.
life is a continuous learning experience, so you may end up changing your profession after graduation. several of my classmates did not pursue mechanical engineering roles.
regardless, good luck and have fun!
