It's from the States but the diver is using a wide scraper blade to clean the hull and it appears to remove very little (precious and pricey) antifoul. Being time poor I do get a diver in to do my hull sometimes but I fear they are using a brush or similar and removing too much ablative. Any divers in Sydney use this technique?
I reckon that is hard antifoul. From memory you have ablative. I wouldnt use metal scrapers on ablative.
We had our hull cleaned once last year. I actually bought some cheap dive gear (second hand from local dive shop) so I could give it a go myself. Watch this space.
Just had it re-antifouled.
We used ablative on the hull (No5) and semi hard stuff (Petite Vivid) on the rudder as the ablative just got washed off.
Would have to be very hard antifoul, as I cannot see any of the blue in the water as he scrapes. Where he knocks off the shell it is going to foul rapidly (unless he paints it later in the vid).

Hi Yara Further into the vid (4.28min) he uses a brush to show the amount of antifoul that is removed. I'm guessing it's ablative. If so, this is a remarkable technique and i need to find someone that uses it!!
Ive been using a similar scraper around the waterline with ablative and you only need a light touch so doesnt remove much paint if any. I also use a standard paint scraper(a new sharp one) to remove a thin layer of old antifoul when on the slip. It works well on ablative when wet and is easier than sanding. Leaves a nice smooth surface too.
A renders/ concreters pointed trowel, does the job you Beauty ! Pointy bit for pokin around / square ends for back hand hacking and two flat sides for sweeping and the way the tool has to be held your knuckles are protected, imho it's the tool for the job

That is a 10 or 12 inc broad knife (plasterers- drywall tool) in the video. they have a lot softer(more flexibility) blade that might be part of the reason he is getting such a nice finish.
That paint in the video is well and truly spent. Would only get another week or so before it needed another rub down. I presumed the diver was removing shell in preparation of going on the slips. Surprised by the amount of shell on the prop that had been coated with propspeed.
Unless you are removing shelled animals or other 3-dimensional growth, a scraper (metal or otherwise) is not an appropriate tool for everyday, all over hull cleaning. Not only does a scraper not really clean well, it will remove or damage anti fouling paint unnecessarily. Here's how boat bottoms should be cleaned:

I shave with a razor(when I'm bothered) I scrap the fuzz off my boat with a stainless brordknife. But I spend a lot of time with a stainless brordknife. And I spend a lot of money at proplaster.
My boat is Quakers Hat Bay and I am told that generally not safe to go in the water there or anywhere in middle harbour. As I have my diving certs can anyone tell me where its is relatively safe and ok to clean my hull?
