Do you have any idea of what you would like to do after you graduate. Are you looking at coastal structures (break waters, jetties piers), underwater vechicles (AUV, ...), offshore structures (Oil rigs), corrosion or naval engineering. I know that Florida Tech had a very strong costal and offshore program, while FAU had a very strong underwater vechical program. I don't know too much about Hawaii, but I believe that they had a strong program in offshore structures. All three are fine schools. I suggest that you look at the courses that they offer, and the area of research that the professors are into. Then base you decision on where your intrests lie. And don't forget that Texas A&M has a very strong prtogram in offshore structures. Hope this helps.
