Seems I haven't stopped learnign since I bought my 350D in November. And I still haven't used the Manual exposure option.
This last weekend I took a number of shots down a jetty in bright sunlight.
I used the aperture-priority mode to set the aperture to f/22 because I wanted the full length of the jetty to be in focus, and took my shots. The 1/60 shutter-speed chosen by the camera resulted in washed out colour with a blue hue.
So, what should I have done? Is this the kind of circumstance in which I should move to M and set both the aperture and shutter-speed? Or should I have used a different light metering?
Most other shots work okay.

It might help us answer your question if you could post some pics....
Maybe you had the wrong white balance.

I suspect your metering picked up something that was fairly dark, perhaps the surface of the jetty? The dark surface biased the exposure positive, because the metering system always tries to put the metered area at mid-gray.

Unfortunately I can't upload any shots. I'm typing from work and the pictures are on my home PC.
If I'm following what you're saying is that if I want a large DOF than the camera should work out the correct shutter-speed to maintain the colours.
The white balance is set to auto. I did take a similar shot with mode P where the colours came out fine (although the DOF was too shallow).
The jetty was unpainted, weathered grey wood; kind of dark. At the end of the jetty there was a green building. Does this help any?

Paul, exposure is quite complicated in high contraast settings like you are explaining. I can only suggest you start looking for info on histograms. Histograms tell you how the light is distributed over the exposure range of the camera. That said, any spike on either end of the histogram will mean blown highlights ot lost detail in shadows. If you go to M, you can tweak either the Aperture or Shutter Speed to get the histogram in a good location, helping you achieve a better exposure. I'd also suggest bracketing for such high-contrast settings.
As far as the blue hue goes. I'd suspect it was either WB being off or UV haze. Don't rely on your camera to get WB right, set it for the appropriate type of light.
And, invest in a UV Haze filter. Not only do they keep UV light entering the sensor to a minimal, but they also protect your precious lens from knicks and scratches.

Thanks all.
Seems I need to continue reading, shooting, and learning.
