Unlock All
Start a new game and race one of the Beginner tracks. You must place well enough to enter your initials in to the high score listing. Enter "?PB" (without quotes) and you will unlock every track, and every boat in the game!! (this includes the Tiny Titanic, Blowfish Armed Response, and Chumdinger)

Quick Start
Hold L during the pre-race countdown. Release L and hold R when the countdown reaches "3". Release R and hold L when the countdown reaches "2". Release L and hold R when the countdown reaches "1". If done correctly, your boat will get a faster start and a four-second boost.

Shortcuts
Far East - After the Blue Boost that's hanging out in the air, you'll hit a bunch of small waterfalls followed by a Tunnel. If you jump on top of the Tunnel, you'll cut you're time in half for that section. Ship Graveyard - After the gigantic fall after the tunnel there will be sharks in the water and a waterfall on the right. If you take the shortcut there will be 1 red boost and 1 blue boost and you can use boost to boost into 6th or 5th depending on where you were before the waterfall. Venice Canals - Towards the beginning of the level, after the second checkpoint, there is a wall with a red arrow pointing left. Usually you would turn a sharp left, then a sharp right (a full 180 degrees) slowing you down and causing you to bump into the walls. But instead of turning that sharp left, just hydro jump over the wall. It will cut about 6 or 7 seconds off of your time and you will end up in 4th or 5th place. Venice Canals #2 - Towards the beginning of this stage there is a wall that has poles coming out of the water and there is a board going across the top of it. Do a hydro jump off that wall and to cut off a lot of time from your race.

Unlock secret boat
In Lake Powell on the starting gate turn right to see a a patch of light brown rocks bump into them and pause and restart the race do this 13 times and go back to the boat selection and there will be ANOTHER BOAT! This may not work if you do not do it correctly, so do not panic.
