Can anyone advise me on the best way to remove completely (to bare wood) years of antifoul?

Lots of hard work and a good scraper. Sandvik tools make a scraper with a tungston carbide blade well worth the investment I have used one before to clean antifouling off a clinker hull it made a hard job a lot easier but be careful when useing it or you could gouge the wood. Always wear respiratory protection when scraping antifouling
I would rather be afloat than ashore.

Agree with the above. I did it this spring on a 38 footer; took several Sandvik blades and respirator filters, but it got done. The Sandvik scraper is much the best tool for the job.

I agree with the other correspondents, although I use a random orbital sander with a vacuum cleaner attached to the dust outlet. There is simply no way to make this job easy. DO NOT use any kind of heating appliance such as heat gun, blow torch, etc., as the vapours from the antifouling will simply kill you.

Re: antifoul scrapers
Have you tried an old 1" file with the end ground at 45%, also round off the corners you cand go wider if you like but the effort is increased, cover up well and use a mask, and drink lots of tea, and promise yourself that what you are doing will be a benifit in the long run.

Yes, I have
a pretty good set of ex-file scrapers, dating from the days when I kept the decks bare teak, so I have some with the tang bent over and sharpened for seam raking, some with the flat end bent over and sharpened as you describe for cleaning off.
They are excellent because of the weight and solidity, but, for a really big antifouling removal job, I got fed up with re-sharpening. That is where the Sandvik tungsten carbide tipped blade scores high marks, and, like a file, it is quite solid and beefy and does not chatter on the surface.

Weigh up cost, the difference between tungsten scrapers and tea and milk for labourers (slaves)

Farrow system, wet blasting, quick effiecient and clean. Costs a bit, but in the long run easier than DIY, thoroughly reccomended, leaves a surface you can prime staright away. I wish it were available in Spain!

Re: antifoul scrapers
About three boats in our marina have had antifoul removed recently by sand blasting,generaly all agree first class job,boats were sheeted from deck down and ground sheets so marina manager could not cpmplain,there is probably a company that does it in your area.
Cost was £12 PER/FT, but 30-35 FT boats easily done in a day,all boats were GRP.
It may be expensive but its quick and efficient with good results.
My surveyor told me years ago he sees more boats with damaged hulls from scrapers than anything,scrap off the flake,sand it, paint it, I use International Prima Con first (painted with brush) then two top coats anti foul, boat in water for two years no problem
Have a nice day antifouling you don need to go to a gym!
Happy sailing
