I seem to recall the 800 I've sailed had quite light load on the jib sheet due to some multi-purchase tackle on it? As much to get fine control as to give power? Maybe check the rigging guide?

The swivel is knackered. Either buy a new one or try tightening the rivet-like thing which is the swivel axis. I think we had a Holt-Allen fitting, which survived as much inept abuse as we could muster. But check the hole spacings before buying one.

I've never had this issue in the 49er or 29er which has similar cleats and sheet loads.  

For reference, the sheet is pretty loaded. The last bit of sheet is squeezed on using a straight arm and my legs. No way I could produce that force above my head with an out stretched arm any other way than shocking the line like in the video. 

Watch dylan here, at 1:40, he's using the same technique as me to flick the rope up. 

Sorry, that last post came across a bit condescending, it was not meant that way.... 

As you say it's pretty impossible to unload the sheet with your arm above your head. Are the sheet loads particularly high on the 800? I know I'm always telling my Spice crews to pull and lift, upwind jib sheet loads are pretty high on the Spice (I don't rig them 2:1) but the cleats are not on a swivel so don't move around. Those Spinlock cleats are brilliant and the Ronstan swivel GRF suggests is a good bit of kit too.

What cleat is it on the swivel, is it as big as a Harken 150.
If it isn't the fact that the swival head (that holds the cleat is moving around) is the diam of the sheet close to the upper limit of the cleat. This can make it hard to "snatch" the sheet out of the cleat.
Is there a fair lead over the top of the cleat, might be worth this being an extreme hi angle one if you can, give the sheet as much room as possible

I'm not surprised you are having trouble. The way a cam cleat works is that the more load on the sheet the harder it grips. Flicking it up will only work if the load is extremely low. To release pull the sheet in to take off the load and lift at the same time.

What's wrong in using British made kit and supporting the British Marine industry?

If it is the right stuff well yes of course ... but would you go for it if it was wrong or just because had a union flag sticker on it ?  Surely not ....

It sounds like Dan has it pretty much right, the bearing is a captive steel plate. The boat is 8 years old, and the cleat could be just as old.
 
Speaking to a few 800 sailors the Harken fitting is fine when new, so it's not an issue as they come out of the factory. However, people often try to bend them (instead of fitting wedges) which splays the captives plates apart introducing a load of play. That or they get stood on or kicked. 

Here's a little video of the issue i'm having. I can generally get if after a few flicks of the sheet when reasonably high wiring. But that's no use when you're sailing past the windward mark, struggling to duck a transom, or being hit by a gust. I'm also having to put so much effort in to uncleating I'm wobbling around with the steering too. 

Anyway, I'm getting a replacement Harken one. A new one should fix the issue. This has done eight years, which is a fair service. If I still have the problem I'll look at other solutions.

What happens if you're not sitting on the windward side?

With my K1 Jib sheet I just use an ordinary fixed cam cleat with an “after” fairlead and this works just fine. Probably not an option in the 800 as you would be too far forward at times for it to work properly?

When I sailed a Contender it was interesting to see how many of the fleet had modified the standard centre mainsheet jammers. I remember we got very paranoid about a mm or so up or down
