9 second booster in Lost Island: 
Enter the first waterfall that appears in the Lost Island track. Jump over the 
lava spout to get a 9 second booster. The waterfalls are the best place to 
find shortcuts and secrets. The best boat to use, once unlocked, is the Tidal 
Blade. It has great maneuverability.

The only way to complete Venice Canals: 
The following steps will help you complete Venice Canals, the hardest level 
(next to Nile Adventure) in the game in the only way possible. First, you must 
get a large amount of boost. A fast boat like the RaD HaZarD is recommended, 
if your good at turning. You must use your hydro jump to jump onto and over 
grass. This will get you ahead of a few racers. Then, you will reach a room 
with swinging chandeliers You have to hydro jump at just the right moment on 
the second chandeliers (there are a total of three). You will get a 9 second 
boost. Use it wisely to win and complete the level.
