not sure if those are splashes. there are several cat manufacturers up in that area that seem to have an intertwined history togather. if its not an original it may be a derivitive from an involvement with ocean express, thats just a guess though. one thing i have heard is Sparkey (owns Viscous) has a pretty good reputation for quality. they build some pretty solid boats up in them thar' parts .
just curious, why do you ask?
