Thanks, Sprout

To be fair, looking at os' starting post, I cheated slightly, as I did have some idea of what I was doing.
Short version: stick your camera in aperture priority mode, set ISO and autofocus point selection to manual (manual focus isn't my thing), and off you go.
Longer version:
- I used a long-ish telephoto zoom (70-300 mm) to get as close to the action as I could without crossing over into the fenced-off areas by the bank of the course.
- Vibration reduction (a handy feature, designed to minimise the effects of camera shake) on the lens was handy - as I had to do some running to get shots of one boat in particular - but not really essential.
- It was a sunny day, so I could use the 'f/8 and be there' rule - most lenses tend to be at their sharpest between f/8 and f/11, apparently - which works best on sunny days like this one.
- High shutter speeds to catch the action best - 1/1000th of a second and up should do the trick.
- Another benefit of very sunny days is that you can set ISO fairly low (I used ISO 200/400 all day). The higher the ISO, the grainier the image, but the faster the shutter speed you can use, so you can get higher shutter speeds in lower light by bumping ISO up.
- Metering modes - how the camera picks a suitable shutter speed in semi-automatic mode - count. I used centre-weighted metering to expose for the bits I was generally aiming for, as the light bouncing off the subjects kept changing depending on where they were on the course. Spot metering would have meant too many blown out backgrounds, and matrix metering would have exposed for the brightest bits of the image.
- Manual autofocus point selection - pick a particular focus point in your viewfinder, make sure this point covers over the thing you're interested in most, focus, take the shot.
Good post, toor.

Thanks.
I'm a lazy bugger, so I just set mine to auto contrast and take my piccies. Although, I often apply the last tip you listed (i.e. manual autofocus point selection).
Just one more tip to add to your list (although not a camera feature): Make sure the horizon is perfectly horizontal. Some cameras have a grid that you can bring up. This helps.
