The previous post has much good advice. I used Interlux one-part for above the toerail, Toplac for white and Brightside for non-skid. But your note seems to be asking about the hull, the bottom and the sides(topsides).
The topsides(waterline to toerail) are gelcoat or paint. And Awlgrip is the best but there are many options. The waterline is usually a black or offsetting color, almost always a paint. Below that bottom-paint.
I took the bottom of my boat down to the original white gelcoat to check for blisters. Then I applied five coats of Interlux 2000E barrier-coat, a 2-part. Over that goes the anti-fouling, in my case Trinidad SR.
Besides the manufacturer''s site there is excellent info here on Sailnet. Do an Article Search for "paint".
