Fair enough. Like I thought you could say do civil engineering and go into marine engineering as a MSc and specialise in ship structures or say mechanical and go into the systems that ships use.(Original post by trapking)
It depends on what the OP finds interesting to study and his career goals but I wouldn't say it would restrict you that much. For example, my project supervisor in my third year (who is a head of automotive engineering research at my last university) did his undergrad in Marine Engineering (at Newcastle as well funnily enough) then did a PhD in Engineering at Bristol. He teaches all the systems engineering modules as well as all the advanced mechanical dynamics modules.
Just shows you/puts into perspective how interlinked a lot of the engineering disciplines actually are despite their names.
Would you pay less for a humanities degree?
