How to watch a hydroplane race
Before the start of each race there is a 5 minute warm up period. This period allows the drivers to take different points of reference on the racecourse before the start as well as to warm the engine oil. At this time it is the green flag that allows drivers to know that they are still in the warm up period.
The white flag is waved a minute before the start. Drivers must set up in their assigned lane and get ready for the start.
A clock is displayed in front of the spectators to show how much time is left in the warm up period.
When the clock arrives at 00:00 the drivers can cross the start line legally. If one of the boats passes the starting point (marked by buoys) before the start of the race it gets an automatic penalty.
Exception Grand Prix class only does 4 laps , drivers must complete 5 laps. A checkered flag is waved to mark the winner’s victory. The racecourse is 1 mile.
