It's one of the four bonus boats. You can only unlock them to get Tinytanic if you unlock the bonus tracks by winning all three hard tracks. Tinytanic is one of the coolest speedboats in the game. You can race it on any of thirteen tracks. If the Tinytanic collects the boost the fourth funnel in the back bends down and shots out a jet flame so it will zoom super fast like the other speed boats. Tinytanic is a cool Titanic speedboat in Hydro Thunder. You would want to use it in any boat race.
