Hint: 180 or better:
Hold Left or Right off a ramp. You can also go to the secret area in Dolphin Park. Charge the wave with turbo and hold Down. Pull back to get some hang time then hold Left or Right.

Hint: Triple Backflip:
Note: This is a sort of glitch so it will not work all of the time. It works off your landing. If you land hard enough at the correct angle, the upward buoyant force of the water on the Jet Ski will cause you to do a third Backflip. Go to free roam mode and then highlight either Nigel Carver or Serena Del Mar. Press Z and move the first green dot three slots away from the acceleration side. Then, move the second green dot one slot away from the tight side. Press A and go to Dolphin Park. Once there, go moderately fast (about 105km/h) and hit a double sided jump. Then, do a Double Backflip (follow the Double Backflip hint, but do not hold B) but keep holding Back. If you are lucky, when you land you will do sort of a bounce and do another flip. Release after your first flip or else you will fall. It is possible to do two extra flips in a row (four flips total).

Hint: Flatspin:
Turn while on a ramp. While you are turning, try to do a back flip at the same time.

Hint: Arctic Bay: Shortcut:
After passing three icebergs and the long right turn, before the ramp, at around 2 o'clock you will se a discoloration in the mountain side. Run into that discoloration and it will open up the underground penguin lair. Bear right and you will see a reunion with all the penguins and a ramp. There are two shortcut options. Either go onto that ramp and dive, which uncovers one shortcut; or go straight, which uncovers a different shortcut.

Hint: Dolphin Park: Hidden area:
In free roam mode, aim for the island in the background when you first start. Just before you hit the "out of bounds" markers, hit the turbo. If done correctly, you will see a second area. Head for that area and when you can hit the turbo a second time, do so to reach it. This may require more than one attempt. This new area has monster waves that you can do any trick on.

Note: Choose a character that has an even, but high, acceleration and top speed.

Hint: Dolphin Park: Jump over small cave:
In free roam mode, go to the small cave "hallway". Stop at the little ramp. Go forward to the last ramp of the set of three that is lined up. Move and hold B until you hit turbo. This should be between the first and second ramps. Then, you pull back on the Analog-stick and you will jump and ride on it as if you were doing a little wheelie.
Frank Keyes.

Hint: Dolphin Park: Jump over archway:
Select free roam mode. Choose Nigel Carver and press Z. Put the first green dot three spaces away from acceleration. Then, move down and put the second green dot one space away from tight. Then, press A. And then select Nigel Carver. Once you have done that, go to Dolphin Park. Go near the three jumps that are near you when you first start. Go over by the piers and do a 180. Next, start driving towards the farthest jump, holding B the entire time. When you get about three quarters of a second away from the jump, press Z and while holding B try to do a Backflip (Up, Down). If done correctly, you should land on or jump completely over the archway.

Hint: La Razza Canal: Shortcut:
Select a character in free roam mode and go to La Razza Canal. From the starting line, go straight then take a right. Next, turn left, then right, then make a U-turn. Once you get out of the narrow alleyway go straight. You will then turn left, go under the two bridges, and go straight. Next, take a U-turn to the right. There will now be two ways to go. Take the left way and go through an alleyway. Take a right and you will see a set of doors. Break through them. There should be a turn and then a ramp. Do not be surprised if you use a turbo.
Ethan and Erica Mayes.

Hint: Lost Temple Lagoon: Shortcut:
Towards the end of the track, as you are on the big turn, is a big brick wall. Run into the wall with your Jet Ski and it will break, giving you an advantage on the race. You can do this in any game mode.
SAFranky.

In hard mode, around the middle is a small brick wall you can break through. Inside is what appears to be an ancient temple. If you go to the other side, you can get out with a commanding lead.
Ricky Stevenson.

Hint: Ocean City Harbor: Shortcut:
After the third jump (ramp), immediately before the fourth jump make a sharp right so that you can see a red gate guarding a tunnel. Go through the gate, which opens a very nice shortcut.
SAFranky.

Hint: Southern Island: Shortcut:
After the shipwreck there is a wall to the left. In the middle of the wall is a hole. Dive to break the bars on the hole and go through it.
Daniel Stubbs.

Hint: Strongwater Keep: Shortcut:
On the second lap after the seventh or so buoy a gate will open up as you pass by. Dart into it, follow the short tunnel, then break the glass at the other end to get out.

After the large jump over the rocks, follow the right wall and find the patch of different colored wall, Break through it to reveal a tight S-curve short cut. Note: You will miss three buoys by taking this shortcut.

Hint: Free roam: Buoys:
Select free roam mode and choose the Fatty and the Dolphin Park track. Go towards the mountain and you will see a ring of buoys. You may need someone fast, as it as hard to get to.

Hint: 1080 Snowboarding reference:
Two of the wave riders are actually snowboarders from the Nintendo 64 game 1080 Snowboarding. They are Ricky Winterborne and Rob Heywood.
