I think you'll find most Jet Ski-ers are pretty well clued up about the rules of the water and know what all the flags/regs are:
Diver down flag = slalom pole
Fishing boat = something to go up to and do a big turn
Swimming area = drag strip
Moorings = good place to tow a fellow tosser in a rubber ring

I hate jet ski's with a passion

They are all driven by the same type of chav scum bag with enough cash to go out and be annoying.

I once came up dead in the middle of the wake of jet ski - i was only a few meters from the rocks and miles away from where they launch. I didn't hear it coming and the first I heard of it was the noise of it going away. You won't hear or see the one that hits you.

Yesterday a boat came within 5m of me despite having a float. This was on a supposedly quite stretch of coast. I few minuits later a gin palace towing a banana passed my buddy too close for comfort. Had to hug the rocks in the end where there were no fish. Discretion is the better part of valour though - 'he had the correct flag up' is of little comfort chiseled on a toombstone.

I am generally agains't excess rules and regs but in the case of Jet-ski's and clueless pleasure craft I'm all for it. They should all have to pass a proper test - i wonder how many people will have to be killed or seriously injured before it happens though...
