Various scrapers are out there, Pull scrapers, Bosch electric, etc, which do we think best for removing old antifouling?
Thanks.

Scrapers
I think that the pull scraper(are they made by Bahco?) are the best. My electric scraper, which admittedly isn't a Bosch but the Lidl £15 quid equivalent is OK if there is a thick edge to work against, but on thinner stuff it's no good. I don't know of an easy way to remove anti fouling.

Sandvik with the 2inch blade. These blades are made of tungsten. You need to blunt the two corners otherwise it will dig in very easily.
Tungsten blade stays sharp for a long time and is good enough to shave gelcoat if you want to.
Alternative if you have a really thick layer - Bosch electric scraper - but you will spend some time sharpening the blade

I found a sharp 2" wood chisel and a Sandvik pull scraper a good combination. You can alternate between the two when your shoulders get tired. A sharp triangular scraper is also effective.
I bought a Harris wallpaper scraper which is cheaper than the Sandvik one, but accepts the expensive Sandvik blades. This tool is the nearest I can find to the much missed Skarsten scraper.

You may find that you need a different tool in different places.
I very much liked the Sandvik, or is it called Bahco now ?
I found that a heavy 2" chisel ground down to a square end worked well in places. It also has a nice bit of weight which seems to help.
I found 3 hour sessions were plenty enough for this job. Took me about 7 sessions to do it and still have my back the next day.
Best of luck.And think of that nice slinky bottom you will have gliding through the sea this season.

Pull Scraper
I have been using various Skarsten scrapers for very many years and find them good. They can be easly sharpened. There are two types of blades, straight and serated. The latter good on thick paint and varnish. It is important to round off the corners when sharpening.

You are right up there now !
Whilst I remember,you may wish to consider the poor old hands in this weather. I am writing this in the hope that I will also remember.
The cracking and the splitting of the fingers is something I suffer more as one matures. Would be nice to wear gloves if you remember.
I have found a cream called "LOTIL" which is brilliant and quick acting for split fingers. Cost £3.19 at the chemists for 50ml. You don't need much either.

Angle grinder?
Pete knows what he's talking about - he spent most of last year trying to remove about 20 layers of anti-fouling from the bottom of his boat. I know - I removed a few square feet for him!
Mind, his boat is now several cwt lighter!

Paint scraper
I just came back from B&Q. They do 2 pull scrapers, Hamilton & Harris. I bought the Hamilton because they used to make paint brushes near where I used to work and those were reckoned to be classy brushes. They both have Tungsten carbide blades but Hamilton is slightly lighter and more comfortable handle. Cost about a tenner with a spare blade (so 4 edges altogether). Harris was slightly more expensive.
One stroke with brand new scraper and blade most impressive but I will have a go at the sharp corners with my diamond sharpener thingy. Don't suppose an ordinary grinding wheel will be much good.

Another vote for the Hamilton because it is cheap, readily available (B&Q) and does the job. The two blades (double sided) were enough to scrape the hull on my 26 footer then lend the tool to someone else. The corners definitely must be ground off before use.
I'm sure the Sandvik will be better but it is more expensive.

A/f removal.. it must be the time of year...
Anyway, I can only comment on removing hard, Trilux, about 5 years worth.
Screwfix Heavy Duty Scraper.. about £6-7.. took a while, but wasnt hard labour, by any means.
Didnt have my Lidl jobbie with me on the day , but I have so many chines I m not sure I'd have used it. I did later try in on the stern, and it was dead easy.

Pull scrapers
One thing we found with the pull scrapers is to keep a sharp blade, the antifouling will come off so much quicker. It can be tempting to soldier on with a blunt blade because of the cost (which isn't that much really) and because the degradation is subtle, but a sharp blade makes the stuff come off much more easily. So get a few spare blades, we found about 4-5 hours of scraping was about the limit before it a new blade was needed.
If you can stand it, do wear a dust mask, the antifouling can do nasty things to you.

Only one scraper is worth the bother.
Google " Linbide Scraper"
Used by painters at work they are so effective that burning off paint has not been done for years.
The corners are sharp and some care is needed but this sharp edge is part of what makes them so effective.
Buy one and try
