In UK waters the shutter speed is largely irrelevant once you stop down. There isn't enough light to give an exposure except at extremely long shutter speeds. The flash exposure is very short (thousands of a second) and this will stop any motion more effectively than short shutter speeds.

I know what you are saying Ken, but both photos shown are at close range, so you could up the shutter speed and close the aperture and let the flash do all the lighting. I think you can see the difference a higher shutter speed makes if you look at my 2 threads on St Abbs last August, on the second trip I was using a much higher speed for close-up work and it made a world of difference (can't remember who on here pointed it out to me). Admittedly if you have fish and reef then it's a different matter in UK/NZ waters.
