I'm trying to take pictures of wakeboarding.

1/2000 automatic Fstop ISO 100

They all came out dark like this. I'm riding in a boat, could the speed of the boat be causing something?

PS - the camera is a digital Rebel XT with a 75-300mm lense in the Tv mode set to 2000 and/or 1000 (but all the pics came out the same) ..... like dark blue instead of nice and bright

Unless you have your camera set for spot metering, it averages the esposure based on the meter readings from several locations in the frame. In this case, you should have used exposure compensation of at least +2.0ev.

I'd never rely on Auto white balance even though most digitals do a great job. For outdoor shooting, pick the appropriate preset wb setting for the conditions.

Here is a quick edit of your image to demonstrate what it should look like.

Closest thing Canon offers for spot metering in the RebelXT and 20D is called partial metering and it covers 9% of the viewfinder, usually not even close for spot metering :?. So you should go with the exposure comp method, or use a hand held spot meter :-) .
The 1d series cameras have a real spot metering mode that covers 2.4% of the viewfinder.

It is what Rodney was talking about.

When shooting a scene with large areas of light in them you set your exposure compensation dial to a +ev value 1,2 sometimes 3 stops for very bright things like sunlit snow fields or bright beaches. You go the other way if there are large areas that are dark.

Your cameras meter is trying hard to turn everything into 18% gray, including the white snow fields/bright beaches, using exposure comp moves the bright/white back to being bright/white, instead of the dull gray that the default setting would have produced.

The exposure stuff in the previous posts was not about a white balance issue.

Auto white balance usually guesses close if you don't wnat to figure out the real color temperature of your light source.
