I have a black and red boat. You need to wash and wax it on a regular basis. Very hard to keep clean. I would say it looks great when it is clean, and everyone knows me because I have a black boat.

Would I get a black boat again??? Hell no, to much work. At least if white is chaulky you can't see it as much. All the blemishes stick out much more, and the boat is hot all the time.

I know from living in Jersey that dark colors aren't as much a problem as they are here in Florida.
An all black hull would be hot enough to fry steaks on down here.
My interior has some teal vinyl sections and nobody can walk on them after being in the sun.

Had black once......royal pain the azz to keep clean. Never again. Looked beautiful when it was clean, and starting looking like crap as soon as the first splash of water hit it.
