Your probably correct, before there were tools like ours, scraping the barnacles of the blades and attempting to acheive a smooth surface finish was entirely manual. But bear in mind that only in the past 25 years (since computers) was any serious study made to calculate the effect that surface smoothness has on the prop dynamics.
How much does one make doing this. doing this under water is so much more effective then grinding away at it in drydock, plus you get a better overall look.
Divers make a decent wage for their efforts. The pay is very good per day (2-400 usd), but the work is never steady. Averaged out over the year, it's probably about what a good plumber would earn. We just have more free time between jobs.....
And with all due respect to you sir, look at the surface condition of the propeller in the areas the diver has not polished. All the deep scratches and gouges in the surface were made in the shipyard by so-called propeller experts. Rule of Thumb: If you can see a clear reflection in the blade after polishing you have achieved a Rupert scale "A" finish. For your further information, this video shows only the first stage of polishing and was posted to display the machine's capability only.
Could the props not be PTFE coated to make it impossible for barnacles to stick to them?

just curious.....before they had tools like this, was propeller polishing/refinishing all done by hand?
