Ok, so I'm chipping an scrapin an hatin every minute. Is it naive to hope there might be a yellow peril to take the slog out of it?
Is there a karcher jet man enough to really strip antifoul?

I feel your pain. I have just finished removing the antifouling from a small boat. RemoveAll 220 paintstripper softened it enough for a chisel to work reasonably well, but the pressure washer had hardly any effect on the paint, though I used it to remove the remaining stripper.

Apart from the drudge and muscle pain, it's the papa smurff blue facial and hair do that really does my head in! And why do family happily turn up to sail, but vanish like snow off a dyke when there's antifoul scraping to be done. Well, at least they're not stoopid!

The Marina petrol driven washer doesn't remove the AF, except a few loose bits, so any Karcher that you would want to afford won't touch it, get scraping. :ambivalence:

Yes.
Your only hope of remission is a 'soda blasting rig'. I know- I've been there, done that, etc....
Oh, and I know a forumite who owns such a rig.... and he's presently at a loose end.

Are you at liberty to divulge his name and whereabouts, please?
ps I could probably throw some work his way fairly imminently if he were willing to venture out east.

My petrol driven Karcher will only remove the flaky bits and barnacles so the hobby ones have no chance.

Actually the reality is more about venturing out west... Thare be dragons in them thar waters out west...

No....My boat is ashore at Fambridge (definitely east coast, not west), and I've recently asked for some quotes to get the antifouling off.
If there's a forumite at a loose end, it'd be great to be able to put the cash in their pocket.

A few years back I had to take a Sigma 41 back to tell coat, removing several layers of hard racing antifoul.
A bosche electric scraper, with the the sharp corners filed down proved very efficient. Almost impossible by hand!

I finished my 28 foot bildge keeler a few weeks ago and am still feeling the pain! However applying the antifoul was a joy 
Next time I am saving up my beer tokens and getting it done professionally.

A Bahco scraper will strip a 38' boat of 10 or 12 coats of old antifoul in 2 8 hour days. Hard work but effective.

Sounds good. Did you have any worries about stripping the gelcoat as well?

That's less than 3000psi at slightly over 3 gallons a minute. The pressure is not really the e issue as that is created by the restriction, Once the water has left the nozzle on the lance it as at atmospheric pressure but has vlecity.
It's the velocity, fan shape and volume that are important. I've had pumps giving 3000psi at 6 gallons a minute for general drain and surface cleaning work, but to cut into hard materials we would hire in skid mounted pumps giving 10,000 psi at 30 or more gallons a minute.
Sort of like this
The systems using a mild abrasive are more effective.

We used one of them to clean scale from the cooling water tunnels in a steel mill, really powerful tool, done the job well, but scary in a small tunnel.

My club has a really nasty three phase jet washer that will remove most of the antifoul ,usually not intentionally ,but last time I used it myself and got most off on purpose.

If you've pressure-washed off all the flaky bits and the remaining antifoul is hard enough to resist further abrasion then why bother scraping the rest off?
Slap on another coat or two and launch!

Couple of years of that and it'll end up like a relief map of the moon. That's usually the point I buy the boat :ambivalence:
