wraps and displaying of brands really doent matter, I come from motocross background and people have been doing it for years and years, displaying brands on their bikes and graphics for local races, just trying to show loyalty to the brands they like even if they don't get any sponsorship from them, so I say if you want to wrap your boat to advertise for a brand like hummingbird or lowrance or abu Garcia , the go for it, cause more than likely its your money that paid for the wrap and all thet stuff anyway
