Animated movie late 90's to early 2000's
Hey cannot remember the title of a movie I used to watch when I was small on sky movies, I can remember it was set underwater or in the sky (not on land) it was about a matey who has to go activate a ancient underwater machine/contraption but he has to find it first. During the movie he learns to fly/pilot sci-fi like underwater ships ( and there's one part where there's mad music in the background with him flying this ship with alloud of luminous ghost like stingrays following/chasing him , I can also remember the main character always wore a white tank top and had light hair (blonde) I think . The movie is similar too disney's atlantis but isn't! Lol
It was mainly 2d animation with the odd computer 3d animation sequence for da ships and stuff
