Im a student and I use solidworks periodically but this is my first attempt at surfacing ive pretty much just watched a bunch of youtube videos to get to this point..

Im modeling a hovercraft and im having trouble with the surface that goes from the passenger compartment to the fan intake (I’ve tried to isolate it in my model so you can see what I’m referring to)

I’m not sure how best to create the surface so that it has a smoother transition. should i break it up in to a few boundry surfaces or just one?

Any help would be great!

(I know the model is kind of sloppy unorganized but I've just been figuring it out as I go..sorry)
