Sahara Movie---what's that yacht?

For any of you who have watched the exciting movie "Sahara", you probably noticed the nice little pleasure yacht they utilized in their voyage. I know it's not a megayacht, but I figured you would be a knowledgable source. I have searched and searched and searched and cannot locate the type of boat that was. Some of my close guesses were Formula Boats (400 SS model) and then maybe a sunseeker performance yacht. But these aren't the boats, they just look like the one in the movie kinda. Does anyone have any intel on what yacht they used to make that movie? Thanks.
