I second getting rid of the mari star decal and maybe even the mastercraft one toward the stern, tint the windows and you're set, i think the single axle trailer takes away from the overall style but it'll look great in the water even if you left it as is.
Maybe get a custom sticker mfg. to make you a cool design for the sides like the mastercraft x logo, or just primer the whole thing black and go murdered out
Boating is less about looks and more about fun had with friends and family on the water, you can be in an aluminum fishing boat with good company or an xstar with some douches and I'd take the fishing boat any day...
