I used to Jet Ski in Margate about 10 years ago on  a borrowed Kawasaki 500cc Jet Bike.  That was a baby compared to this 700cc monster. 

I haven't been near the sea let alone on a Jet Bike for years and the first day I went out the sea was like glass and it was an exhilarating experience - enough to get me back into it. But not adrenalin pumping or taxing enough - so I waited till the sea was 'rough', (a four day wait), before I went out again.

It was 'awesome' crashing into the waves, getting enough lift to raise the whole bike 5-10ft out of the water and then crashing back down onto the next wave (this is like hitting concrete at 30 mph) and just generally zooming around - ye ha I was in heaven.
