This number depends on the skill level you've chosen. The Championship and Slalom modes are only accessible after you've completed certain other parts of the game. And again, winning the various championships will give you even more options to choose from. The big bonus is a whole new set of powerboats to choose amongst. There are two types, monohulls and catamarans.
Catamarans are faster and have more horsepower than monohulls, thus they are much harder to control.
A catamaran also has two hulls, as opposed to a monohull. The different skill levels have great influence on the speed and horsepower of your vessel. Prepare for long hours of trial and error, as the toughest skill level is frightfully difficult. We find ourselves quite comfortable with Powerboat Racing 's carefree gameplay. Like in any other arcade game, the real fun lies in challenging friends in beating each other's best times.
